Release: WSJT-X 2.3.0-rc3

Jan 6, 2021

|
|
|
-------------------------
|
|
|
|
|
|
|
|
|
|
|
|
WSJT-X 2.3.0 Release Candidate 3 adds an improved FST4W decoder and
|
|
|
|
|
|
fixes several defects and regressions discovered since the second
|
|
|
|
|
|
release candidate.
|
|
|
|
|
|
|
|
|
|
|
|
- FST4W: Improve FST4W decoder sensitivity on fading channels and
|
|
|
|
|
|
decrease false decode rate.
|
|
|
|
|
|
|
|
|
|
|
|
FST4W uses 50-bit messages and a 24-bit CRC. The 74-bit
|
|
|
|
|
|
message+CRC is encoded into a 240-bit codeword. Received messages
|
|
|
|
|
|
are decoded by two different decoders: (i) a “belief propagation”
|
|
|
|
|
|
(BP) decoder and (ii) an ordered statistics decoder (OSD). The
|
|
|
|
|
|
ordered statistics decoder has a knob that allows any or all CRC
|
|
|
|
|
|
bits to be treated as additional parity bits rather than as part of
|
|
|
|
|
|
the message+CRC field. Thus, the OSD decoder can decode the
|
|
|
|
|
|
received message as a (240,50+Nc) code, where Nc is any integer
|
|
|
|
|
|
between 0 and 24. In the RC1 and RC2 releases the OSD decoding
|
|
|
|
|
|
attempt treated the code as a (240,64) code (14-bit CRC). This
|
|
|
|
|
|
release uses 2 OSD decoding attempts that treat the received word
|
|
|
|
|
|
as (i) a (240,66) code with 16-bit CRC and code rate 0.308 and (ii)
|
|
|
|
|
|
a (240,50) code with no CRC and code rate 0.208. Codewords returned
|
|
|
|
|
|
by the (240,50) CRC-less decoding attempt are unpacked and the
|
|
|
|
|
|
decode is printed only if it contains a callsign/grid pair that
|
|
|
|
|
|
have been previously decoded by the belief propagation decoder
|
|
|
|
|
|
(which treats the code as a (240,74) code with 24-bit CRC) or the
|
|
|
|
|
|
ordered statistics decoder configured for (240,66) (16-bit
|
|
|
|
|
|
CRC). The callsign/grid memory is stored in file “fst4w_calls.txt”
|
|
|
|
|
|
which resides in the data directory.
|
|
|
|
|
|
|
|
|
|
|
|
- FT8: Fixed a crash triggered by double clicking on the waterfall to
|
|
|
|
|
|
invoke a decode of a signal in the preceding T/R interval.
|
|
|
|
|
|
|
|
|
|
|
|
- FST4W: Do not save .c2 files.
|
|
|
|
|
|
|
|
|
|
|
|
- FST4W: Correct a bug that could cause incorrect operation when
|
|
|
|
|
|
using negative noise blanker (NB) percentage to trigger looping
|
|
|
|
|
|
over a range of NB percentages.
|
|
|
|
|
|
|
|
|
|
|
|
- fst4sim: Added simulation of Lorentzian fading spectrum, invoked by
|
|
|
|
|
|
negative fspread values.
|
|
|
|
|
|
|
|
|
|

Release: WSJT-X 2.3.0-rc2
|
|
|
|
|
|
Nov 16, 2020
|
|
|
|
|
|
-------------------------
|
|
|
|
|
|
|
|
|
|
|
|
WSJT-X 2.3.0 Release Candidate 2 fixes issues found in RC1 and
|
|
|
|
|
|
includes some new functionality that missed the RC1 cut off deadline.
|
|
|
|
|
|
|
|
|
|
|
|
- Dropped audio samples message box removed, warnings and errors for
|
|
|
|
|
|
these are now sent to the WSJT-X system log.
|
|
|
|
|
|
|
|
|
|
|
|
- FST4W spots to WSPRNet.org will be augmented such that the server
|
|
|
|
|
|
can distinguish the mode being spotted. Spots to WSPRNet.org will
|
|
|
|
|
|
no longer be restricted to WSPR sub-bands.
|
|
|
|
|
|
|
|
|
|
|
|
- A new internal system and data logging facility used to provide
|
|
|
|
|
|
trace, debug, information, warning, error, and fatal error
|
|
|
|
|
|
messages. The verbosity and filtering of messages is user definable
|
|
|
|
|
|
via a configuration file. Without a configuration file a basic log
|
|
|
|
|
|
is written with information, warning and error messages only. Log
|
|
|
|
|
|
files are automatically rotated to limit disk usage.
|
|
|
|
|
|
|
|
|
|
|
|
- Due to some users using inappropriate multicast IP addresses for
|
|
|
|
|
|
their interoperating severs the default behaviour now is to only
|
|
|
|
|
|
send multicast UDP datagrams to the loop-back network interface.
|
|
|
|
|
|
Users who require WSJT-X UDP Message Protocol datagrams to reach
|
|
|
|
|
|
other hosts will now have to configure WSJT-X to send on an
|
|
|
|
|
|
appropriate network interface, and use an appropriately scoped
|
|
|
|
|
|
multicast group address for their server applications. If you are
|
|
|
|
|
|
not sure then 224.0.0.1 (or ff02::1 if IPv6 is desired) is a safe
|
|
|
|
|
|
choice.

|
|
|
|
WSJT-X 2.3.0 is a program upgrade offering two new modes designed
|
|
|
|
|
|
especially for use on the LF and MF bands. FST4 is for 2-way QSOs,
|
2020-09-26 11:02:02 -04:00
|
|
|
|
and FST4W is for WSPR-like transmissions. Both modes offer a range of
|
2020-09-26 20:26:36 -04:00
|
|
|
|
options for T/R sequence lengths and threshold decoding sensitivities
|
|
|
|
|
|
extending well into the -40 dB range. Early tests have shown these
|
2020-09-26 11:02:02 -04:00
|
|
|
|
modes frequently spanning intercontinental distances on the 2200 m and
|
2020-09-26 20:26:36 -04:00
|
|
|
|
630 m bands. Further details and operating hints can be found in the
|
2020-09-26 11:02:02 -04:00

Release: WSJT-X 2.2.2
|
|
|
|
|
|
June 22, 2020
|
|
|
|
|
|
---------------------
|
|
|
|
|
|
|
|
|
|
|
|
WSJT-X v2.2.2 is a bug fix release, mainly to incorporate the new RAC
|
|
|
|
|
|
section PE into the FT8/FT4/MSK144 Contest Mode for Field Day.
|
|
|
|
|
|
|
|
|
|
|
|
- Stations intending to operate in Field Day (FD) are urged to
|
|
|
|
|
|
upgrade to this release, without it you cannot set your section to
|
|
|
|
|
|
PE, and of equal importance you cannot decode contest messages from
|
|
|
|
|
|
stations who are operating from PE without this upgrade.
|
|
|
|
|
|
|
|
|
|
|
|
- FT8 decoder speeded up in Normal and Fast modes. This change gives
|
|
|
|
|
|
a speed of decoding closer to that of v2.1.2 without compromising
|
|
|
|
|
|
the number of decodes. It is particularly targeted for slower
|
2020-06-21 18:25:45 -04:00
|
|
|
|
single board computer users such as the Raspberry Pi Model 3 or
|
2020-06-21 18:24:05 -04:00
|
|
|
|
similar.
|
|
|
|
|
|
|
|
|
|
|
|
- Thanks to our user interface language translation contributors for
|
|
|
|
|
|
many improvements to the translated strings.
|
|
|
|
|
|
|
|
|
|
|
|
- The DX Grid field is now cleared automatically when the DX Call
|
|
|
|
|
|
field is changed. Care should be taken to complete entry of a
|
|
|
|
|
|
callsign before entering a grid square.

WSJT-X v2.2.1 is a bug fix release that fixes regressions found in the
|
|
|
|
|
|
prior v2.2.0 release. Here is a brief summary;
|
|
|
|
|
|
|
|
|
|
|
|
- Incorporate a revised Hamlib version the address a regression in
|
|
|
|
|
|
rig control of some rigs including the Yaesu FT-991 and FT-891.
|
|
|
|
|
|
|
|
|
|
|
|
- Repair a defect in 6 character gridsquare lookup from the CALL3.TXT
|
|
|
|
|
|
database, and improve "Lookup" button processing.
|
|
|
|
|
|
|
|
|
|
|
|
- Repair a defect with selecting Wide Graph 2D spectrum types in
|
|
|
|
|
|
translated UIs.
|
|
|
|
|
|
|
|
|
|
|
|
- Repair a regression that blocked the Highlight Callsign UDP request
|
|
|
|
|
|
from highlighting terms including a '+' character.
|
|
|
|
|
|
|
2020-06-06 10:15:21 -04:00
|
|
|
|
- Repair a defect that caused hash code lookups of one's own call to
|
|
|
|
|
|
fail after an extended period of inactivity, when operating with a
|
|
|
|
|
|
non-standard callsign.
|
|
|
|
|
|
|
2020-06-05 18:34:57 -04:00
|
|
|
|
- Repair a regression where occasional Highlight Callsign UDP
|
|
|
|
|
|
requests with the 'Highlight last' parameter as true highlighted a
|
|
|
|
|
|
match in a prior period. This fix include a performance improvement
|
|
|
|
|
|
when processing any Highlight Callsign request with 'Highlight
|
|
|
|
|
|
last' as true.
|
|
|
|
|
|
|
|
|
|
|
|
- Include support for the Yaesu FT-920 when controlled by Ham Radio
|
|
|

Release: WSJT-X 2.2
|
|
|
|
|
|
June 2, 2020
|
|
|
|
|
|
-------------------
|
|
|
|
|
|
|
|
|
|
|
|
WSJT-X 2.2 is a program upgrade that provides a number of new features
|
|
|
|
|
|
and capabilities. Here is a brief summary; for further details see
|
|
|
|
|
|
the notes for candidate releases 2.2.0-rc1, -rc2, and -rc3, below, and
|
|
|
|
|
|
of course the updated WSJT-X 2.2 User Guide.
|
|
|
|
|
|
|
|
|
|
|
|
- Significant improvements to the decoders for FT4, FT8, JT4, JT65,
|
|
|
|
|
|
and WSPR.
|
|
|
|
|
|
|
|
|
|
|
|
- New format for "EU VHF Contest" Tx2 and Tx3 messages
|
|
|
|
|
|
|
|
|
|
|
|
When "EU VHF Contest" is selected, the Tx2 and Tx3 messages (those
|
|
|
|
|
|
conveying signal report, serial number, and 6-character locator)
|
|
|
|
|
|
now use hashcodes for both callsigns. This change is NOT backward
|
|
|
|
|
|
compatible with earlier versions of _WSJT-X_, so all users of EU
|
|
|
|
|
|
VHF Contest messages should be sure to upgrade to version 2.2.0.
|
|
|
|
|
|
|
|
|
|
|
|
- Accessibility
|
|
|
|
|
|
|
|
|
|
|
|
Keyboard shortcuts have been added as an aid to accessibility:
|
|
|
|
|
|
Alt+R sets Tx4 message to RR73, Ctrl+R sets it to RRR.
|
|
|
|
|
|
|
|
|
|
|
|
As an aid for partial color-blindness, the "inverted goal posts"
|
|
|
|
|
|
marking Rx frequency on the Wide Graph's frequency scale are now
|
|
|
|
|
|
rendered in a darker shade of green.
|
|
|
|
|
|
|
|
|
|
|
|
- User Interface Translations have been enabled. Translations are
|
|
|
|
|
|
now available for Catalan, Spanish, Japanese, Chinese, and Hong
|
|
|
|
|
|
Kong Chinese. Additiional languages will follow, when available.
|
|
|
|
|
|
|
|
|
|
|
|
Note that UI translation is automatic, based on your system primary
|
|
|
|
|
|
language. If you do not want the WSJT-X UI translated to your local
|
|
|
|
|
|
language then start WSJT-X with the '--language=en' command line
|
|
|
|
|
|
option:
|
|
|
|
|
|
|
|
|
|
|
|
wsjtx --language=en
|
|
|
|
|
|
|
|
|
|
|
|

|
|
|
|
|
|
|
|
|
|
|
|
- Minor enhancements and bug fixes
|
|
|
|
|
|
|
|
|
|
|
|
"Save None" now writes no .wav files to disk, even temporarily.
|
|
|
|
|
|
|
|
|
|
|
|
An explicit entry for "WW Digi Contest" has been added to
|
|
|
|
|
|
"Special operating activities" on the "Settings | Advanced" tab.
|
|
|
|
|
|
|
|
|
|
|
|
Contest mode FT4 now always uses RR73 for the Tx4 message.
|
|
|
|
|
|
|
|
|
|
|
|
The Status bar now displays the number of decodes found in the
|
|
|
|
|
|
most recent Rx sequence.
|
|
|
|
|
|
|
|
|
|
|
|
The "Highlight Callsign" UDP message has been enhanced to allow
|
|
|
|
|
|
clearing of old highlighting for a specified callsign. Please note
|
|
|
|
|
|
a recommended restriction on the use of this message in the
|

Release: WSJT-X 2.2.0-rc3
|
|
|
|
|
|
May 30, 2020
|
|
|
|
|
|
-------------------------
|
|
|
|
|
|
|
|
|
|
|
|
WSJT-X 2.2.0-rc3 is the third release candidate for WSJT-X 2.2.0.
|
|
|
|
|
|
|
|
|
|
|
|
The most important differences from the -rc2 version are the
|
|
|
|
|
|
correction of regressions in hamlib code that affected particular
|
|
|
|
|
|
radios and PTT keying by means of DTR or RTS on a COM port.
|
|
|
|
|
|
|
|
|
|
|
|
In addition, RC3 has the following enhancements and minor bug fixes:
|
|
|
|
|
|
|
|
|
|
|
|
- Updates to Catalan translation of the UI (thanks to EA3W)
|
|
|
|
|
|
- Spanish translation of the UI (EA3W)
|
|
|
|
|
|
- Load language translations only when matching primary language
|
|
|
|
|
|
- Minor corrections to User Guide
|
|
|
|
|
|
- Increased FT8 sync threshold in "Normal" and "Fast" decoding
|
|
|
|
|
|
- Corrected the code that restores the WideGraph, EchoGraph, and
|
|
|
|
|
|
FastGraph windows to normal view after they have been minimized.
|
|
|
|
|
|
- Don't allow restart with "ISCAT B" mode label unless VHF features
|
|
|
|
|
|
are enabled.
|
|
|
|
|
|
- Repair regression defect in WSPR power combo box items

Release: WSJT-X 2.2.0-rc2
|
|
|
|
|
|
May 25, 2020
|
|
|
|
|
|
-------------------------
|
|
|
|
|
|
|
|
|
|
|
|
WSJT-X 2.2.0-rc2 is a release candidate for WSJT-X 2.2.0. The
|
|
|
|
|
|
following bugs present in the -rc1 version have been fixed:
|
|
|
|
|
|
|
|
|
|
|
|
- Missing blank line between some decode sequences.
|
|
|
|
|
|
- Improper functioning of "Start new period decodes at top".
|
|
|
|
|
|
- Font selection caused crash on some macOS systems.
|
|
|
|
|
|
- Mouse action in band selector box not right in some macOS systems.
|
|
|
|
|
|
- Incorrect recall of Tx power setting in WSPR mode.
|
|
|
|
|
|
- Many fixes to hamlib library and executables (rigctld, etc.).
|
|
|
|
|
|
- Some regional settings did not allow WSJT-X to start.
|
|
|
|
|
|
- Main window "looked like old Windows" in macOS.
|
|
|
|
|
|
- Crash when "Ref Spec" is selected and no refspec.dat available.
|
|
|
|
|
|
- Improper decoding of some FT4 messages with hashed "MyCall".
|
|
|
|
|
|
- Crash after warning message about double-clicking in ISCAT mode.
|
|
|
|
|
|
|
|
|
|
|
|
In addition, we have made the following improvements:
|
|
|
|
|
|
|
|
|
|
|
|
- Updated some figures and text in User Guide.
|
|
|
|
|
|
- Corrected some formatting issues in the pdf version of User Guide.
|
|
|
|
|
|
- Added some new sample files.
|
|
|
|
|
|
- Improved shape and position of "green goal post" in Wide Graph.
|
|
|
|
|
|
- Significantly reduced the rate of false decodes in FT4 and FT8.
|
|
|
|
|
|
- Allow FT4 to use NA VHF Contest message formats.
|
|
|
|
|
|
- Hold Tx frequency no longer cleared when switching between modes.
|
|
|
|
|
|
- Added capability for translations of the user interface into
|
|
|
|
|
|
languages other than English. First working example (special
|
|
|
|
|
|
thanks to Xavi Perez, EA3W!), is Catalan. Spanish will be next.
|
|
|
|
|
|
- Performance improvements to decode highlighting via UDP messages.
|
|
|
|
|
|
|
|
|
|
|
|
And finally:
|
|
|
|
|
|
|
|
|
|
|
|
Increasing FT8 usage on the popular bands 40, 30, and 20m means that
|
|
|
|
|
|
the default 3 kHz sub-bands are often wall-to-wall with signals.
|
|
|
|
|
|
Overcrowding encourages some to turn on their amplifiers, which only
|
|
|
|
|
|
makes things worse. We are trying to coordinate the suggested
|
|
|
|
|
|
frequencies in WSJT-X with updated band plans being considered by
|
|
|
|
|
|
IARU, ARRL, and other amateur radio societies.
|
|
|
|
|
|
|
|
|
|
|
|
On a trial basis, and in response to numerous suggestions from around
|
|
|
|
|
|
the world, we have added a second set of suggested dial frequencies
|
|
|
|
|
|
for FT8 on three HF bands and also on 6 meters. The new suggested dial
|
|
|
|
|
|
frequencies are 7.071, 10.133, 14.071, and 50.310 MHz. These
|
|
|
|
|
|
frequencies will appear in your drop-down band-selector list after you
|
|
|
|
|
|
go to the "Settings | Frequencies" tab, right-click on the frequency
|
|
|
|
|
|
table, and select "Reset". Alternatively, you can add the new FT8
|
|
|
|
|
|
frequencies manually.
|
|
|
|
|
|
|
|
|
|
|
|
When the conventional FT8 sub-band on 6, 20, 30, or 40 m seems too
|
|
|
|
|
|
full, please try moving your dial frequency down 3 kHz! Be aware that
|
|
|
|
|
|
as currently implemented, WSJT-X will set your dial to the lowest
|
|
|
|
|
|
frequency for the selected mode and band, when you switch bands.
|
|
|
|
|
|
|
|
|
|
|
|

Release: WSJT-X 2.2.0-rc1
|
|
|
|
|
|
May 10, 2020
|
|
|
|
|
|
-------------------------
|
|
|
|
|
|
|
|
|
|
|
|
WSJT-X 2.2.0-rc1 is a beta-quality release candidate for a program
|
|
|
|
|
|
upgrade that provides a number of new features and capabilities. These
|
|
|
|
|
|
include:
|
|
|
|
|
|
|
|
|
|
|
|
- Improvements to the decoders for five modes:
|
|
|
|
|
|
|
|
|
|
|
|
FT4: Corrected bugs that prevented AP decoding and/or multi-pass
|
|
|
|
|
|
decoding in some circumstances. The algorithm for AP
|
|
|
|
|
|
decoding has been improved and extended.
|
|
|
|
|
|
|
|
|
|
|
|
FT8: Decoding is now spread over three intervals. The first
|
|
|
|
|
|
starts at t = 11.8 s into an Rx sequence and typically yields
|
|
|
|
|
|
around 85% of the possible decodes for the sequence. You
|
|
|
|
|
|
therefore see most decodes much earlier than before. A second
|
|
|
|
|
|
processing step starts at 13.5 s, and the final one at 14.7 s.
|
|
|
|
|
|
Overall decoding yield on crowded bands is improved by 10% or
|
|
|
|
|
|
more. (Systems with receive latency greater than 0.2 s will see
|
|
|
|
|
|
smaller improvements, but will still see many decodes earlier
|
|
|
|
|
|
than before.)
|
|
|
|
|
|
|
|
|
|
|
|
JT4: Formatting and display of Averaged and Deep Search decodes
|
|
|
|
|
|
has been cleaned up and made consistent with other modes.
|
|
|
|
|
|
Together with JT65 and QRA64, JT4 remains one of the digital
|
|
|
|
|
|
modes widely for EME and other extreme weak-signal work on
|
|
|
|
|
|
microwave bands.
|
|
|
|
|
|
|
|
|
|
|
|
JT65: Many improvements for Averaged and Deep Search decodes and
|
|
|
|
|
|
their display to the user. These improvements are particularly
|
|
|
|
|
|
important for EME on VHF and UHF bands.
|
|
|
|
|
|
|
|
|
|
|
|
WSPR: Significant improvements have been made to the WSPR
|
|
|
|
|
|
decoder's sensitivity, its ability to cope with many signals in
|
|
|
|
|
|
a crowded sub-band, and its rate of undetected false decodes.
|
|
|
|
|
|
We now use up to three decoding passes. Passes 1 and 2 use
|
|
|
|
|
|
noncoherent demodulation of single symbols and allow for
|
|
|
|
|
|
frequency drifts up to ±4 Hz in a transmission. Pass 3 assumes
|
|
|
|
|
|
no drift and does coherent block detection of up to three
|
|
|
|
|
|
symbols. It also applies bit-by-bit normalization of the
|
|
|
|
|
|
single-symbol bit metrics, a technique that has proven helpful
|
|
|
|
|
|
for signals corrupted by artifacts of the subtraction of
|
|
|
|
|
|
stronger signals and also for LF/MF signals heavily contaminated
|
|
|
|
|
|
by lightning transients. With these improvements the number of
|
|
|
|
|
|
decodes in a crowded WSPR sub-band typically increases by 10 to
|
|
|
|
|
|
15%.
|
|
|
|
|
|
|
|
|
|
|
|
- New format for "EU VHF Contest" Tx2 and Tx3 messages
|
|
|
|
|
|
|
|
|
|
|
|
When "EU VHF Contest" is selected, the Tx2 and Tx3 messages
|
|
|
|
|
|
(those conveying signal report, serial number, and 6-character
|
|
|
|
|
|
locator) now use hashcodes for both callsigns. This change is
|
|
|
|
|
|
NOT backward compatible with earlier versions of _WSJT-X_, so
|
|
|
|
|
|
all users of EU VHF Contest messages should be sure to upgrade
|
|
|
|
|
|
to versiion 2.2.0.
|
|
|
|
|
|
|
|
|
|
|
|
- Accessibility
|
|
|
|
|
|
|
|
|
|
|
|
Keyboard shortcuts have been added as an aid to accessibility:
|
|
|
|
|
|
Alt+R sets Tx4 message to RR73, Ctrl+R sets it to RRR.
|
|
|
|
|
|
|
|
|
|
|
|
As an aid for partial color-blindness, the "inverted goal posts"
|
|
|
|
|
|
marking Rx frequency on the Wide Graph's frequency scale are now
|
|
|
|
|
|
rendered in a darker shade of green.
|
|
|
|
|
|
|
|
|
|
|
|
- Minor enhancements and bug fixes
|
|
|
|
|
|
|
|
|
|
|
|
"Save None" now writes no .wav files to disk, even temporarily.
|
|
|
|
|
|
|
|
|
|
|
|
An explicit entry for "WW Digi Contest" has been added to
|
|
|
|
|
|
"Special operating activities" on the "Settings | Advanced" tab.
|
|
|
|
|
|
|
|
|
|
|
|
Contest mode FT4 now always uses RR73 for the Tx4 message.
|
|
|
|
|
|
|
|
|
|
|
|
The Status bar now displays the number of decodes found in the
|
|
|
|
|
|
most recent Rx sequence.
|
|
|
|
|
|
|
|
|
|
|
|
Release candidate WSJT-X 2.2.0-rc1 will be available for beta-testing
|
|
|
|
|
|
for one month starting on May 10, 2020. We currently plan a General
|
|
|
|
|
|
Availability (GA) release of WSJT-X 2.2.0 on June 1, 2020.
|
|
|
|
|
|
|
|
|
|
|
|
For those looking even farther ahead: We are well along in the
|
|
|
|
|
|
development of two new modes designed for the LF and MF bands. One
|
|
|
|
|
|
mode is for WSPR-like activity and one for making 2-way QSOs. Both
|
|
|
|
|
|
use Low-density Parity Check (LDPC) codes, 4-GFSK modulation, and
|
|
|
|
|
|
two-minute T/R sequences. The QSO mode reaches threshold SNR
|
|
|
|
|
|
sensitivity around -31 dB on the AWGN channel, and the WSPR-like mode
|
|
|
|
|
|
better than -32 dB.

Release: WSJT-X 2.0
|
|
|
|
|
|
December 10, 2018
|
|
|
|
|
|
-----------------------
|
2019-02-24 22:07:51 -05:00
|
|
|
|
|
|
|
|
|
|
WSJT-X 2.0 is a major update that introduces new protocols for FT8 and
|
|
|
|
|
|
MSK144. The new protocols become the world-wide standards on December
|
|
|
|
|
|
10, 2018.
|
|
|
|
|
|
|
|
|
|
|
|
WSJT-X 2.0 cannot communicate in these modes with other stations using
|
|
|
|
|
|
WSJT-X v1.9.1 or earlier.
|
|
|
|
|
|
|
|
|
|
|
|
Please help by urging everyone to upgrade no later than January 1, 2019.
|
|
|
|
|
|
|
|
|
|
|
|
New features since WSJT-X v1.9.1:
|
|
|
|
|
|
|
|
|
|
|
|
1. Compound and nonstandard callsigns are automatically recognized and
|
|
|
|
|
|
handled using new message formats.
|
|
|
|
|
|
|
|
|
|
|
|
2. The new FT8 protocol provides optimized message formats for North
|
|
|
|
|
|
American VHF contests, European VHF contests, ARRL Field Day, and ARRL
|
|
|
|
|
|
RTTY Roundup. Similarly, the new MSK144 protocol provides optimized
|
|
|
|
|
|
message formats for North American VHF and European VHF contests.
|
|
|
|
|
|
Full support is provided for "/R" and "/P" calls in the relevant
|
|
|
|
|
|
contests.
|
|
|
|
|
|
|
|
|
|
|
|
3. The new protocols provide nearly equal (or better) sensitivity
|
|
|
|
|
|
compared to the old ones, and lower false decode rates.
|
|
|
|
|
|
|
|
|
|
|
|
4. New logging features are provided for contesting and for "Fox"
|
|
|
|
|
|
(DXpedition) mode. Logging is optionally integrated with N1MM Logger+
|
|
|
|
|
|
and WriteLog.
|
|
|
|
|
|
|
|
|
|
|
|
5. Color highlighting of decoded messages provides worked-before
|
|
|
|
|
|
status for callsigns, grid locators, DXCC entities, continents, CQ
|
|
|
|
|
|
Zones, and ITU zones on a “by band” and “by mode” basis, and for
|
|
|
|
|
|
stations that have uploaded their logs to Logbook of the World (LoTW)
|
|
|
|
|
|
within a specified time interval.
|
|
|
|
|
|
|
|
|
|
|
|
6. The WSPR decoder now achieves decodes down to S/N = -31 dB. For
|
|
|
|
|
|
the particular benefit of LF/MF users, an option "No own call decodes"
|
|
|
|
|
|
has been added.
|
|
|
|
|
|
|
|
|
|
|
|
7. The UDP messages sent to companion programs have been expanded and
|
|
|
|
|
|
improved.
|
|
|
|
|
|
|
|
|
|
|
|
Some details of changes since WSJT-X-rc5 include the following:
|
|
|
|
|
|
|
|
|
|
|
|
- Initial load of ADIF log in background
|
|
|
|
|
|
- Correct the UTC displayed in Fox/Contest log
|
|
|
|
|
|

|
|
|
|
|
|
- Fix improper truncation of some non-FT8 messages in ALL.TXT
|
|
|
|
|
|
- Various minor bug fixes and code cleanup
|
|
|
|
|
|
- Update the WSJT-X User Guide to v2.0 (more to come...)
|
|
|
|

|
|
|
|
|
|
Release Candidate 5 ("RC5") is stable, works well, and fixes the known
|
|
|
|
|
|
problems in RC4. It is likely that the General Availability (GA)
|
|
|
|
|
|
release of WSJT-X 2.0 will be nearly identical to RC5.
|
|
|
|
|
|
|
|
|
|
|
|
Changes from WSJT-X 2.0-rc4 include the following:
|
|
|
|
|
|
|
|
|
|
|
|
- Make the "Auto Seq" checkbox sticky, again
|
|
|
|
|
|
- Remove the 5-minute mouse timer
|
|
|
|
|
|
- Correct the "worked before" logic for color highlighting
|
|
|
|
|
|
- Add "No own call decodes" checkbox in WSPR mode
|
|
|
|
|
|
- Display and log UTC (not local time) in contest operations
|
|
|
|
|
|
- Validate contest QSO details before allowing logging
|
|
|
|
|
|
- Force Aqua theme on macOS to avoid issues with Mojave dark theme
|
|
|
|
|
|

|
|
|
|
|
|
- Improve layout of Working Frequencies and Station Information tables
|
|
|
|
|
|
- Allow deletes and editing in Fox and Contest log windows
|
|
|
|
|
|
- Add Tool Tips for Fox and Contest log windows
|
|
|
|
|
|
- Fix a bug causing false AP decodes in JT65 VHF+ operation
|
|
|
|
|
|
- Fix a bug that could switch unexpectedly from JT65 to JT9 mode
|
|
|
|
|
|
|
|
|
|
|
|
PLEASE NOTE: As far as WSJT-X 2.0 (RC4, RC5, and GA releases) are
|
|
|
|
|
|
concerned, signals using the old FT8 protocol are undecodable
|
|
|
|
|
|
interference. This means that regenerated replicas cannot be
|
|
|
|
|
|
subtracted from received data, and consequently second- and third-pass
|
|
|
|
|
|
decodes may be impeded. Full performance of the 77-bit decoder will
|
|
|
|
|
|
not be realized until most signals on a crowded band are using the
|
|
|
|
|
|
new FT8 protocol.

- Corrected a flaw that encoded a message's first callsign as
|
|
|
|
|
|
hexadecimal telemetry data if the call consisted only of letters
|
|
|
|
|
|
A-F and digits 0-9.
|
|
|
|
|
|
|
|
|
|
|
|
- Corrected program logic that failed to identify certain callsigns
|
|
|
|
|
|
as "nonstandard".
|
|
|
|
|
|
|
|
|
|
|
|
- Fixed a bug that color-highlighted bare CQ messages (no grid
|
|
|
|
|
|
locator) as "New DXCC".
|
|
|
|
|
|
|
|
|
|
|
|
- Fixed a bug that failed to log Report Sent if MyCall is a
|
|
|
|
|
|
nonstandard call.
|
|
|
|
|
|
|
|
|
|
|
|
- Fixed a bug that generated incorrect MSK144 tones for certain
|
|
|
|
|
|
messages and caused a "memory" effect on stations receiving the
|
|
|
|
|
|
incorrect tones.
|
|
|
|
|
|
|
|
|
|
|
|
- Fixed several bugs that could cause certain Tx messages to crash
|
|
|
|
|
|
the program.
|
|
|
|
|
|
|
|
|
|
|
|
- Suppressed the display of certain illogical false decodes.

This is the full General Availability release of WSJT-X Version 1.8.0.
|
|
|
|
|
|
|
|
|
|
|
|
Changes from WSJT-X Version 1.8.0-rc3 are very minor:
|
|
|
|
|
|
|
|
|
|
|
|
- Right-click on the Wide Graph now pops up a Context Menu. Select
|
|
|
|
|
|
the item *Set Rx & Tx Offset* to complete a one-handed setting of
|
|
|
|
|
|
both red and green frequency markers.
|
|
|
|
|
|
|
|
|
|
|
|
- Several clarifications and additions to Tool Tips and the User Guide.
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
We recommend that all users should upgrade to WSJT-X Version 1.8.0.
|
|
|
|
|
|
|
|
|
|
|
|
If you upgrade from v1.8.0-rc1 it may be necessary to do a one-time
|
|
|
|
|
|
reset of the default list of suggested operating frequencies. Go to
|
|
|
|
|
|
*File->Settings->Frequencies*, right click on the table and select
|
|
|
|
|
|
*Reset*.

Release: WSJT-X Version 1.8.0-rc3
|
|
|
|
|
|
October 16, 2017

|
---------------------------------
|
2018-06-22 08:19:05 -04:00
|
|
|
|
|
|
|
|
|
|
Most (but not all) changes since Version 1.8.0-rc2 involve user
|
|
|
|
|
|
control of the increasingly popular FT8 mode. The "RC3" release also
|
|
|
|
|
|
includes minor bug fixes and updates to the WSJT-X User Guide.
|
|
|
|
|
|
|
|
|
|
|
|
The following list includes all of the more important changes:
|
|
|
|
|
|
|
|
|
|
|
|
- New optimization of GUI for simplex and split behavior in FT8 mode.
|
|
|
|
|
|
|
|
|
|
|
|
1. Checkbox "Lock Tx Freq" on main window is relabeled "Hold Tx Freq".
|
|
|
|
|
|
|
|
|
|
|
|
2. Double-clicking on decoded messages that do not contain your own
|
|
|
|
|
|
call moves both Rx and Tx frequencies. If the first callsign is
|
|
|
|
|
|
your own call, only Rx freq moves.
|
|
|
|
|
|
|
|
|
|
|
|
3. Double-clicking on decoded messages moves the Rx frequency. If
|
|
|
|
|
|
"Hold Tx Freq" is checked, Tx frequency is moved only if CTRL was
|
|
|
|
|
|
held down.
|
|
|
|
|
|
|
|
|
|
|
|
4. Clicking on the waterfall moves Rx and Tx frequencies as
|
|
|
|
|
|
before: Rx only on a simple click, Tx only on SHIFT-click, and
|
|
|
|
|
|
both on CTRL-click. This happens even if "Hold Tx Freq" is
|
|
|
|
|
|
checked.
|
|
|
|
|
|
|
|
|
|
|
|
- Add a semi-automated "FreqCal" procedure: see *Solve for calibration
|
|
|
|
|
|
parameters* on the Tools menu.
|
|
|
|
|
|
|
|
|
|
|
|
- Improv auto-sequencing behavior: stop and on-frequency
|
|
|
|
|
|
transmission if a called station comes back to someone else.
|
|
|
|
|
|
|
|
|
|
|
|
- Improve S/N estimation in some situations involving QRM.
|
|
|
|
|
|
|
|
|
|
|
|
- Fix an initialization issue with user-modified application fonts.
|
|
|
|
|
|
|
|
|
|
|
|
- Fix an issue with Tx5 message generation with Type 2 compound calls.
|
|
|
|
|
|
|
|
|
|
|
|
- Enhance and improve the ADIF parser of logbook records. Update
|
|
|
|
|
|
the band limits as per ADIF 3.0.6 specification.
|
|
|
|
|
|
|
|
|
|
|
|
- Increase the FT8 DT range to +/- 2.5 s.
|
|
|
|
|
|
|
|
|
|
|
|
- Do not allow window manager events to close the astronomical data
|
|
|
|
|
|
window.
|
|
|
|
|
|
|
|
|
|
|
|
- Add an "Erase" item to the context (right-click) menu for decoded
|
|
|
|
|
|
text.
|
|
|
|
|
|
|
|
|
|
|
|
- Extend UDP messages with an "off air" boolean field indicating that
|
|
|
|
|
|
the decode was derived from a .WAV file playback rather than an on air
|
|
|
|
|
|
reception.
|
|
|
|
|
|
|
|
|
|
|
|
- Extend reference applications to use the new off air decode message
|
|
|
|
|
|
field.
|
|
|
|
|
|
|
|
|
|
|
|
- Improve performance of FT8 decoder, especially for overlapping
|
|
|
|
|
|
signals.
|
|
|
|
|
|
|
|
|
|
|
|
- Allow specialized use of "x2 Tone Spacing" in FT8 and slow JT9
|
|
|
|
|
|
modes.
|
|
|
|
|
|
|
|
|
|
|
|
- Move "NA VHF Contest Mode" checkbox to main screen. Query the
|
|
|
|
|
|
operator if d > 10000 km.
|
|
|
|
|
|
|
|
|
|
|
|
- Adjust UI to improve portability with font size changes and between
|
|
|
|
|
|
platforms.
|
|
|
|
|
|
|
|
|
|
|
|
- Extend UDP Reply message to support keyboard modifiers. This allows
|
|
|
|
|
|
UDP servers to emulate keyboard modified double-clicks on decoded
|
|
|
|
|
|
messages, e.g. ALT+double-click for replying to a CQ or QRZ call
|
|
|
|
|
|
without changing ones Tx frequency offset.
|
|
|
|
|
|
|
|
|
|
|
|
- Update the cty.dat file (21st Sept 2017).
|
|
|
|
|
|
|
|
|
|
|
|
- Ensure that Fast Graph is properly initialized.
|
|
|
|
|
|
|
|
|
|
|
|
- Better handling of worked before and country name display. Appended
|
|
|
|
|
|
text is added at a fixed column unless the message overlaps in which
|
|
|
|
|
|
case the appended information floats to the right.
|
|
|
|
|
|
|
|

|
|
|
|
|
|
|
|
|
Implementation of FT8 and its auto-sequencing feature is now more
|
|
|
|
|
|
capable and more polished. The decoder is faster and better: it now
|
|
|
|
|
|
includes signal subtraction, multi-pass decoding, and the use of
|
|
|
|
|
|
accumulated "a priori" information as a QSO progresses. Sensitivity
|
|
|
|
|
|
extends downward as far as -24 dB in some circumstances. Overlapping
|
|
|
|
|
|
signals 2 and 3 deep are frequently decoded at essentially the same
|
|
|
|
|
|
frequency. On a crowded band we sometimes see more than 30 decodes in
|
|
|
|
|
|
a single 15-second interval, over a 2 kHz window. The North American
|
|
|
|
|
|
VHF Contesting Mode has been extended to include both FT8 and MSK144
|
|
|
|
|
|
modes.
|
|
|
|
|
|
|
|
|
|
|
|
The "RC2" release also includes many minor bug fixes and an
|
|
|
|
|
|
extensively updated WSJT-X User Guide.
|
|
|
|
|
|
|
|
|
|
|
|
Depending on what code revision you upgrade from, it may be necessary
|
|
|
|
|
|
to do a one-time reset of the default list of suggested operating
|
|
|
|
|
|
frequencies. Go to *File->Settings->Frequencies*, right click on
|
|
|
|
|
|
the table and select *Reset*.

Brief Description of the FT8 Protocol
|
|
|
|
|
|
-------------------------------------
|
2018-06-22 08:19:05 -04:00
|
|
|
|
|
|
|
|
|
|
WSJT-X Version 1.8.0 includes a new mode called FT8, developed by K9AN
|
|
|
|
|
|
and K1JT. The mode name "FT8" stands for "Franke and Taylor, 8-FSK
|
|
|
|
|
|
modulation". FT8 uses 15-second T/R sequences and provides 50% or
|
|
|
|
|
|
better decoding probability down to -20 dB on an AWGN channel. An
|
|
|
|
|
|
auto-sequencing facility includes an option to respond automatically
|
|
|
|
|
|
to the first decoded reply to your CQ. FT8 QSOs are 4 times faster
|
|
|
|
|
|
than those made with JT65 or JT9. FT8 is an excellent mode for HF
|
|
|
|
|
|
DXing and for situations like multi-hop E_s on 6 meters, where deep
|
|
|
|
|
|
QSB may make fast and reliable completion of QSOs desirable.
|
|
|
|
|
|
|
|
|
|
|
|
Some important characteristics of FT8:
|
|
|
|
|
|
|
|
|
|
|
|
- T/R sequence length: 15 s
|
|
|
|
|
|
- Message length: 75 bits + 12-bit CRC
|
|
|
|
|
|
- FEC code: LDPC(174,87)
|
|
|
|
|
|
- Modulation: 8-FSK, tone spacing 6.25 Hz
|
|
|
|
|
|
- Constant-envelope waveform
|
|
|
|
|
|
- Occupied bandwidth: 50 Hz
|
|
|
|
|
|
- Synchronization: 7x7 Costas arrays at start, middle, and end
|
|
|
|
|
|
- Transmission duration: 79*1920/12000 = 12.64 s
|
|
|
|
|
|
- Decoding threshold: -20 dB; several dB lower with AP decoding
|
|
|
|
|
|
- Multi-decoder finds and decodes all FT8 signals in passband
|
|
|
|
|
|
- Optional auto-sequencing and auto-reply to a CQ response
|
|
|
|
|
|
- Operational behavior similar to JT9, JT65
|
|
|
|
|
|
|
|
|
|
|
|
We plan to implement signal subtraction, two-pass decoding, and use of
|
|
|
|
|
|
a priori (AP) information in the decoder. These features are not yet
|
|
|
|
|
|
activated in v1.8.0.
|
|
|
|
|
|
|
|
|
|
|
|
We haven't yet finalized what the three extra bits in the message
|
|
|
|
|
|
payload will be used for. Suggestions are welcome!

WSJT-X v1.6.0 Release Notice
|
|
|
|
|
|
============================
|
|
|
|
|

New Features
|
|
|
|
|
|
------------
|
|
|
|
|
|
|
|
|
|
|
|
WSPR mode, including coordinated automatic band-hopping and a new
|
|
|
|
|
|
two-pass decoder that can decode overlapping signals.
|
|
|
|
|
|
|
|
|
|
|
|
EME-motivated features including JT4 (submodes A-G), Echo mode, and
|
|
|
|
|
|
automatic Doppler tracking. The JT4 decoder is more sensitive than
|
|
|
|
|
|
that in the latest WSJT, and message averaging is fully automated.
|
|
|
|
|
|
(Note that submodes JT65B and JT65C are also present in Version 1.6,
|
|
|
|
|
|
but the high-sensitivity decoder required for EME with JT65 is not yet
|
|
|
|
|
|
included.)
|
|
|
|
|
|
|
|
|
|
|
|
Tools for accurate frequency calibration of your radio, so you can be
|
|
|
|
|
|
always on-frequency to within about 1 Hz.
|
|
|
|
|
|
|
|
|
|
|
|
Mode-specific standard working frequencies accessible from the
|
|
|
|
|
|
drop-down band selector.

Maintenance
|
|
|
|
|
|
-----------
|
|
|
|
|
|
|
|
|
|
|
|
A number of corrections to the Hamlib library, fixing balky
|
|
|
|
|
|
rig-control features. A few unreliable features peculiar to
|
|
|
|
|
|
particular radios have been removed.

WSJT-X v1.5.0 Release Notice

============================

|
|
|
Decoder Performance Improvements
|
|
|
|
|
|
--------------------------------
|
|
|
|
|
|
|
|
|
|
|
|
The most notable change in v1.5.0 is improved speed and quality of the
|
|
|
|
|
|
JT9 and JT65 decoders. Algorithms have been fine-tuned, and advantage
|
|
|
|
|
|
is taken of the multiple CPUs found on most modern computers. Overall
|
|
|
|
|
|
speedup factors of three or more have been attained since the v1.4.0
|
|
|
|
|
|
release and more signals are being successfully decoded as well.
|
|
|
|
|
|
|
|
|
|
|
|
For those interested, here's a summary of speed tests of three
|
|
|
|
|
|
benchmark versions of WSJT-X, based on reading and decoding an
|
|
|
|
|
|
identical set of 10,682 *.wav files. The files were recorded on
|
|
|
|
|
|
various bands from 160 m to 10 m; the number of decodable JT65 signals
|
|
|
|
|
|
is typically about 5 times the number of JT9 signals. For each test
|
|
|
|
|
|
the program was set to "JT9+JT65" mode with "Deepest" selected on the
|
|
|
|
|
|
*Decode* menu. Other setup parameters were identical in all cases.
|
|
|
|
|
|
The test computer runs Windows 7 and has an Intel i5-2500 processor
|
|
|
|
|
|
with 4 CPUs.
|
|
|
|
|
|
|
|
|
|
|
|
Columns labeled "JT9" and "JT65" in the following table give the
|
|
|
|
|
|
number of decoded signals in each mode. Numbers in the "Time" column
|
|
|
|
|
|
are total processing time in seconds, and columns labaled "Factor"
|
|
|
|
|
|
give ratios of the corresponding numbers, relative to WSJT-X v1.3.
|
|
|
|
|
|
|
|
|
|
|
|
Program Version JT9 Factor JT65 Factor Time Factor
|
|
|
|
|
|
-------------------------------------------------------
|
|
|
|
|
|
v1.3 r3673 7691 1.000 40831 1.000 14061 1.00
|
|
|
|
|
|
v1.4.0 7693 1.000 41796 1.024 13320 1.06
|
|
|
|
|
|
v1.5.0-rc1 8024 1.043 43946 1.076 4224 3.32
|
|
|
|
|
|
|
|
|
|
|
|
On the benchmark computer the decoder in v1.5.0-rc1 is more than 3
|
|
|
|
|
|
times faster than the ones in program releases v1.3 r3673 and v1.4.0.
|
|
|
|
|
|
At the same time, the number of decoded signals has increased by as
|
|
|
|
|
|
much as 7.6%.
|
|
|
|
|
|
|
|
|
|
|
|
Users will notice another consequence of taking advantage of multiple
|
|
|
|
|
|
CPUs. JT65 and JT9 decodes in dual "JT9+JT65" mode are now done in
|
|
|
|
|
|
parallel, so decodes are delivered to the Rx activity window as they
|
|
|
|
|
|
are decoded rather than finishing the current mode before starting the
|
|
|
|
|
|
other mode. Decoding at the QSO frequency is still given priority,
|
|
|
|
|
|
but it may not be the first decode displayed because the first decodes
|
|
|
|
|
|
of the other mode may be produced more quickly. Dual mode decodes are
|
|
|
|
|
|
now interleaved in the Rx activity window.
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
UDP Broadcast
|
|
|
|
|
|
-------------
|
|
|
|
|
|
|
|
|
|
|
|
WSJT-X v1.5.0 introduces a new facility that broadcasts status, decode
|
|
|
|
|
|
and logged QSO information via the network. Although this facility
|
|
|
|
|
|
gives no obvious change to the application other than a few new
|
|
|
|
|
|
settings options, it should allow cooperating applications to interact
|
|
|
|
|
|
with WSJT-X far more smoothly than the current file based mechanism
|
|
|
|
|
|
which is prone to contention. The file access contention can be
|
|
|
|
|
|
detrimental to both WSJT-X and the cooperating application whereas the
|
|
|
|
|
|
new broadcast mechanism will not.
|
|
|
|
|
|
|
|
|
|
|
|
Currently the only only cooperating application we know of is JTAlertX
|
|
|
|
|
|
by Laurie VK3AMA and that currently uses the file based mechanism. We
|
|
|
|
|
|
hope that Laurie will try the new mechanism but we will continue to
|
|
|
|
|
|
provide the file based mechanism as well. We also know of at least one
|
|
|
|
|
|
other application in development for the Apple Mac platform to provide
|
|
|
|
|
|
similar features to JTAlertX. A contribution for Linux would also be
|
|
|
|
|
|
most welcome.

|

|
Rig Control
|
|
|
|
|
|
-----------
|
|
|
|
|
|
|
|
|
|
|
|
This continues to be an area of development. There are still many
|
|
|
|
|
|
untested combinations of equipment since we have to wait until a user
|
|
|
|
|
|
tries WSJT-X for the first time with each combination before we can be
|
|
|
|
|
|
sure that any defects have been removed. Hundreds of hours of testing
|
|
|
|
|
|
have been done and we thank those who have reported issues and offered
|
|
|
|
|
|
their time to test fixes where necessary.

FlexRadio & HPSDR Users
|
|
|
|
|
|
-----------------------
|
|
|
|
|
|
|
|
|
|
|
|
Currently the Hamlib library that we use for direct CAT control of
|
|
|
|
|
|
your rigs does not provide a fully functioning driver for these
|
|
|
|
|
|
radios. Instead the TS-2000 emulation mode of these SDRs must be used
|
|
|
|
|
|
as the Hamlib driver for this has tweaks added to cooperate correctly
|
|
|
|
|
|
with SDRs. Version v1.4 of WSJT-X did not work with these radios in
|
|
|
|
|
|
TS-2000 emulation mode and at the time we were not informed of that,
|
|
|
|
|
|
it appears to have become common knowledge that using the TS-480
|
|
|
|
|
|
emulation mode was the correct procedure, this is incorrect although
|
|
|
|
|
|
it did work at the time. The TS-480 emulation may cease to work in a
|
|
|
|
|
|
future version because it is due to a defect in Hamlib that it works
|
|
|
|
|
|
at all. The TS-2000 emulation mode is the correct selection and should
|
|
|
|
|
|
be used with these radios.
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
Generated Messages for Type 1 and Type 2 Compound Callsigns
|
|
|
|
|
|
-----------------------------------------------------------
|
|
|
|
|
|
|
|
|
|
|
|
This is a complex area because it requires special action by both
|
|
|
|
|
|
parties in a QSO since the automatically generated standard messages
|
|
|
|
|
|
are not always suitable. We have tried to improve the standard message
|
|
|
|
|
|
generation and recognition along with better recognition of own call
|
|
|
|
|
|
messages. As before it is imperative that operators take note of their
|
|
|
|
|
|
QSO partners responses and be prepared to manually edit replies when
|
|
|
|
|
|
communicating with compound callsign stations.

WSJT-X v1.4.0 Release Notice
|
|
|
|
|
|
============================
|
|
|
|
|
|
|
|
|
|
|
|
Migration of User Files
|
|
|
|
|
|
-----------------------
|
|
|
|
|
|
|
|
|
|
|
|
This release includes a new install mechanism that separates user
|
|
|
|
|
|
files from installation and program files. This means that going
|
|
|
|
|
|
forward upgrades will be seamless with user files preserved and
|
|
|
|
|
|
automatically carried forward without user intervention. For this
|
|
|
|
|
|
release only it is necessary to move your user files manually if you
|
|
|
|
|
|
wish to preserve them. The locations of user files have changed and
|
|
|
|
|
|
now vary depending on the installation platform. The following notes
|
|
|
|
|
|
are intended to guide you in moving your user files, this is a one
|
|
|
|
|
|
time action.
|
|
|
|
|
|
|
|
|
|
|
|
On Microsoft Windows:
|
|
|
|
|
|
|
|
|
|
|
|
The new location for user files is %LOCALAPPDATA% which is an
|
|
|
|
|
|
environment variable defined automatically by Windows, you may use the
|
|
|
|
|
|
environment variable any place where a file path would normally be
|
|
|
|
|
|
used e.g. in the location entry bar in Windows File Explorer or in
|
|
|
|
|
|
arguments to command line programs from a Command Prompt window.
|
|
|
|
|
|
|
|
|
|
|
|
On Linux and other Unix systems:
|
|
|
|
|
|
|
|
|
|
|
|
The new location for user files ~/.local/share
|
|
|
|
|
|
|
|
|
|
|
|
On Mac:
|
|
|
|
|
|
|
|
|
|
|
|
The new location for user files is ~/Library/Application\ Support
|
|
|
|
|
|
|
|
|
|
|
|
In all cases the files are stored in a subdirectory which by default
|
|
|
|
|
|
is WSJT-X
|
|
|
|
|
|
|
|
|
|
|
|
In the case of users who run multiple instances of WSJT-X on a single
|
|
|
|
|
|
computer there are different user file locations for each
|
|
|
|
|
|
instance. The non-default locations are in sibling subdirectories each
|
|
|
|
|
|
suffixed by the rig name argument passed to WSJT-X at startup (See
|
|
|
|
|
|
Running Multiple Instances below).
|
|
|
|
|
|
|
|
|
|
|
|
The user files that you may wish to migrate from older versions of
|
|
|
|
|
|
WSJT-X are:
|
|
|
|
|
|
|
|
|
|
|
|
ALL.TXT
|
|
|
|
|
|
CALL3.TXT
|
|
|
|
|
|
wsjtx.log
|
|
|
|
|
|
wsjtx_log.adi
|
|
|
|
|
|
|
|
|
|
|
|
The format of each of these files is unchanged in WSJT-X v1.4 so all
|
|
|
|
|
|
that is needed is to copy them to the new location.
|
|
|
|
|
|
|
|
|
|
|
|
For example on Microsoft Windows assuming a WSJT-X v1.3 installation
|
|
|
|
|
|
in C:\WSJT\wsjtx-1.3, using a command prompt window:
|
|
|
|
|
|
|
|
|
|
|
|
copy C:\WSJT\wsjtx-1.3\ALL.TXT %LOCALAPPDATA%\WSJT-X\
|
|
|
|
|
|
copy C:\WSJT\wsjtx-1.3\CALL3.TXT %LOCALAPPDATA%\WSJT-X\
|
|
|
|
|
|
copy C:\WSJT\wsjtx-1.3\wsjtx.log %LOCALAPPDATA%\WSJT-X\
|
|
|
|
|
|
copy C:\WSJT\wsjtx-1.3\wsjtx_log.adi %LOCALAPPDATA%\WSJT-X\
|
|
|
|
|
|
|
|
|
|
|
|
On Linux:
|
|
|
|
|
|
|
|
|
|
|
|
cp ~/wsjtx-1.3/ALL.TXT ~/.local/share/WSJT-X/
|
|
|
|
|
|
cp ~/wsjtx-1.3/CALL3.TXT ~/.local/share/WSJT-X/
|
|
|
|
|
|
cp ~/wsjtx-1.3/wsjtx.log ~/.local/share/WSJT-X/
|
|
|
|
|
|
cp ~/wsjtx-1.3/wsjtx_log.adi ~/.local/share/WSJT-X/
|
|
|
|
|
|
|
|
|
|
|
|
On Mac:
|
|
|
|
|
|
|
|
|
|
|
|
cp ~/wsjtx-1.3/ALL.TXT ~/Library/Application\ Support/WSJT-X/
|
|
|
|
|
|
cp ~/wsjtx-1.3/CALL3.TXT ~/Library/Application\ Support/WSJT-X/
|
|
|
|
|
|
cp ~/wsjtx-1.3/wsjtx.log ~/Library/Application\ Support/WSJT-X/
|
|
|
|
|
|
cp ~/wsjtx-1.3/wsjtx_log.adi ~/Library/Application\ Support/WSJT-X/
|
|
|
|
|
|
|
|
|
|
|
|
If you have a customized cty.dat file installed, then that too should
|
|
|
|
|
|
be copied to the new directory.
|
|
|
|
|
|
|
|
|
|
|
|

Settings
|
|
|
|
|
|
--------
|
|
|
|
|
|
|
|
|
|
|
|
WSJT-X v1.4 introduces a new settings regime. There is no facility to
|
|
|
|
|
|
migrate settings from prior versions and copying the wsjtx.ini
|
|
|
|
|
|
settings file to the new user files location will not carry over any
|
|
|
|
|
|
useful information. The new settings dialog is very different from
|
|
|
|
|
|
prior versions but it is intuitive and will not take long to configure
|
|
|
|
|
|
for you equipment and preferences.
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
Running Multiple Instances
|
|
|
|
|
|
--------------------------
|
|
|
|
|
|
|
|
|
|
|
|
For users with multiple radios or multi-receiver SDRs WSJT-X offers
|
|
|
|
|
|
multiple instance support. Prior to WSJT-X v1.4 this involved
|
|
|
|
|
|
installing the application multiple times in separate locations, this
|
|
|
|
|
|
is no longer necessary and multiple instances MUST be run from a
|
|
|
|
|
|
single installation. This is possible as user and other writable data
|
|
|
|
|
|
files are stored in a unique location for each instance.
|
|
|
|
|
|
|
|
|
|
|
|
WSJT-X has a new command line option that coordinates multiple
|
|
|
|
|
|
instances called --rig-name (-r for short) which allow you to specify
|
|
|
|
|
|
a unique key for each instance. If no --rig-name option is supplied a
|
|
|
|
|
|
default location is used for writable files as specified in the
|
|
|
|
|
|
Migrating of User Files section above. If a key is provided then the
|
|
|
|
|
|
same key must be used every time that instance is started so as to
|
|
|
|
|
|
associate it with the correct data files.
|
|
|
|
|
|
|
|
|
|
|
|
If the unique key were ft-857 then you must start WSJT-X using that
|
|
|
|
|
|
key e.g.
|
|
|
|
|
|
|
|
|
|
|
|
wsjtx --rig-name=ft-857
|
|
|
|
|
|
|
|
|
|
|
|
and the data files will be stored in a directory "WSJT-X - ft-857" for
|
|
|
|
|
|
example on Windows:
|
|
|
|
|
|
|
|
|
|
|
|
"%LOCALAPPDATA%\WSJT-X - ft-857\"
|
|
|
|
|
|
|
|
|
|
|
|
Multiple instance support may also be used if more than one operator
|
|
|
|
|
|
uses the same computer with their own call signs, or a single operator
|
|
|
|
|
|
who operates in multiple locations with different call signs or
|
|
|
|
|
|
wishing to maintain separate log files for each location.
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
Known Issues
|
|
|
|
|
|
------------
|
|
|
|
|
|
|
|
|
|
|
|
Editing station details in the frequencies tab of the settings window
|
|
|
|
|
|
may not save the changes to the settings file. Updates will show in
|
|
|
|
|
|
the settings tables until application exit but may not be used by the
|
|
|
|
|
|
application. A workaround is available, delete the whole row and
|
|
|
|
|
|
re-enter the details rather than editing individual fields. This
|
|
|
|
|
|
defect is resolved in the next release (v1.5).

October 7, 2013: Version 1.2.1, r3590
|
|
|
|
|
|
|
|
|
|
|
|
Windows Vista has a broken rate converter which gets invoked when an
|
|
|
|
|
|
input audio stream at 48kHz sample rate is requested. To correct this
|
|
|
|
|
|
problem, WSJT-X revision 3590 reverts to input sampling at 12000 Hz by
|
|
|
|
|
|
default when run under Vista. All other platforms use 48000 Hz sample
|
|
|
|
|
|
rate for both input and output.
|
|
|
|
|
|
|
|
|
|
|
|

|
|
|
|
|
|
|
|
|
|
3. Clear the logbook "Name" field after logging a QSO.
|
|
|
|
|
|
|
|
|
|
|
|
4. Add tuning paramegters for better audio performance on some machines.
|
|
|
|
|
|
|
|
|
|
|
|
5. Improved handling of displayed text when larger fonts are used.
|
|
|
|
|
|
|
|
|
|
|
|
6. Fix message truncation when a callsign is unexpectedly long.
|
|
|
|
|
|
|
|
|
|
|
|
7. Fix the "stuck decode" bug experienced by some users.
|
|
|
|
|
|
|
|
|
|
|
|
8. Remove the bogus error message sometimes printed upon program exit.
|
|
|
|
|
|
|
|
|
|
|
|

|
|
|
|
|
August 17, 2013: Version 1.2, r3563
|
|
|
|
|
|
------------------------------------
|
|
|
|
|
|
Changes since revision 3556 include the following:
|
|
|
|
|
|
|
|
|
|
|
|
1. Fix bug preventing program restart with "+2 kHz" already set.
|
|
|
|
|
|
|
|
|
|
|
|
2. Fix bug causing problems if program is installed in a directory
|
|
|
|
|
|
with embedded space(s) in the name.
|
|
|
|
|
|
|
|
|
|
|
|
3. Fixed an audio input problem (seen on some computers) by moving
|
|
|
|
|
|
audio input to the audio thread, running at High Priority.
|
|
|
|
|
|
|
|
|
|
|
|
4. Re-enabled the capability for running multiple instances.
|
|
|
|
|
|
|
|
|
|
|
|
August 16, 2013: Version 1.2, r3556
|
|
|
|
|
|
------------------------------------
|
|
|
|
|
|
Changes since code revision 3520 include the following:
|
|
|
|
|
|
|
|
|
|
|
|
1. Audio I/O now uses Qt's built-in multimedia library inatead of
|
|
|
|
|
|
PortAudio. User options are provided for input (mono/left/right) and
|
|
|
|
|
|
output (mono/left/right/both), and a digital attenuation slider to
|
|
|
|
|
|
control Tx audio level. In "Split Tx" mode, Tx signals are now
|
|
|
|
|
|
cleaner because Tx audio is constrained to the range 1500 - 2000 Hz.
|
|
|
|
|
|
|
|
|
|
|
|
2. Windows reports to PSKReporter now use our own code, rather than
|
|
|
|
|
|
PSKReporter.dll.
|
|
|
|
|
|
|
|
|
|
|
|
3. Many new optional palettes for waterfall colors, selectable from a
|
|
|
|
|
|
drop-down list on the Wide Graph window.
|
|
|
|
|
|
|
|
|
|
|
|
4. Fixed bug causing misalignment of Cumulative spectrum when start
|
|
|
|
|
|
frequency is not 0. Decoding begins at start frequency rather than
|
|
|
|
|
|
0 Hz.
|
|
|
|
|
|
|
|
|
|
|
|
5. Tx message #6 is now selected at program startup.
|
|
|
|
|
|
|
|
|
|
|
|
6. Faster logbook lookup when "Show DXCC entity and worked B4 status"
|
|
|
|
|
|
is selected. Also better ADIF compatibility and better text alignment
|
|
|
|
|
|
in left and right text windows.
|
|
|
|
|
|
|
|
|
|
|
|
7. Improved Tool Tips for on-screen controls.
|
|
|
|
|
|
|
|
|
|
|
|
8. Various other code changes for uniformity across platforms, ease of
|
|
|
|
|
|
maintenance, and good programming practice. (Most of these will be
|
|
|
|
|
|
invisible to users.)
|
|
|
|
|
|
|
|
|
|
|
|
9. Program is now built with the latest Qt, version 5.1.
|
|
|
|
|
|
|
|
|
|
|
|
10. Updates to User's Guide.
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
August 2, 2013: Version 1.1.1, r3520
|
|
|
|
|
|
------------------------------------
|
|
|
|
|
|
Improvements since Version 1.1, r3496 include the following:
|
|
|
|
|
|
|
|
|
|
|
|
1. New organization of the "Band Settings" tab on the configuration
|
|
|
|
|
|
screen, including antenna descriptions for PSK Reporter on a "per
|
|
|
|
|
|
band" basis.
|
|
|
|
|
|
|
|
|
|
|
|
2. Full control is provided for DTR and RTS lines on the serial port
|
|
|
|
|
|
used for CAT control.
|
|
|
|
|
|
|
|
|
|
|
|
3. Optional user control of font sizes. Use a text editor to create a
|
|
|
|
|
|
file "fonts.txt" in the WSJT-X installation directory. It should have
|
|
|
|
|
|
four numbers on a single line. The first two are point size and
|
|
|
|
|
|
weight (0-100 scale) for GUI labels, the next two are point size and
|
|
|
|
|
|
weight for the decoded text windows. For example, try "9 50 12 100".
|
|
|
|
|
|
|
|
|
|
|
|
4. New user control at bottom of Wide Graph window sets the start
|
|
|
|
|
|
frequency of the waterfall scale.
|
|
|
|
|
|
|
|
|
|
|
|
5. New optional palette "gray1" for the waterfall.
|
|
|
|
|
|
|
|
|
|
|
|
6. The small colored button just right of the "+2 kHz" checkbox now
|
|
|
|
|
|
shows the letter "S" if "Split Tx" has been checked.
|
|
|
|
|
|
|
|
|
|
|
|
7. New user option appends DXCC country name and "QSO B4" status to
|
|
|
|
|
|
decoded CQ messages.
|
|
|
|
|
|
|
|
|
|
|
|
8. Setting of dial frequencies through Commander should should now
|
|
|
|
|
|
be aware of local convention for decimal separator.
|
|
|
|
|
|
|
|
|
|
|
|
9. Several minor bug fixes.
|
|
|
|
|
|
|
|
|
|
|
|
10. Refactoring of code to move audio input.output into the GUI thread.
|
|
|
|
|
|
(Should be invisible to users).
|
|
|
|
|
|
|
|
|
|
|
|
11. Updated credits displayed in the "About" window.
|
|
|
|
|
|
|
|
|

July 19, 2013: Version 1.1, r3496
|
|
|
|
|
|
---------------------------------
|
|
|
|
|
|
This is a full release of WSJT-X Version 1.1. It provides an easy way
|
|
|
|
|
|
to make QSOs in both JT65 and JT9 modes.
|
|
|
|
|
|
|
|
|
|
|
|
Changes from the most recent beta release, r3487, include the
|
|
|
|
|
|
following:
|
|
|
|
|
|
|
|
|
|
|
|
1. Significant optimizations of the JT9 decoder, providing speed
|
|
|
|
|
|
improvements up to 5 times.
|
|
|
|
|
|
|
|
|
|
|
|
2. Frequency-setting through DX Lab Commander now works properly at
|
|
|
|
|
|
non-integral kHz frequencies.
|
|
|
|
|
|
|
|
|
|
|
|
3. A new meter widget has been added (thanks to PY2SDR).
|
|
|
|
|
|
|
|
|
|
|
|
4. Implementation of "multiple instances" has been completed and
|
|
|
|
|
|
tested (thanks to KK1D).
|
|
|
|
|
|
|
|
|
|
|
|
5. Several minor bug fixes.
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
July 15, 2013: Version 1.1 Beta Release, r3487
|
|
|
|
|
|
----------------------------------------------
|
|
|
|
|
|
|
|
|
|
|
|
Version 1.1 of WSJT-X is "bi-lingual" -- it transmits and receives
|
|
|
|
|
|
both JT9 and JT65 signals, switching between modes automatically as
|
|
|
|
|
|
needed. The maximum displayed bandwidth has been increased from 1 to
|
|
|
|
|
|
5 kHz. If your receiver has an upper-sideband filter at least 4 kHz
|
|
|
|
|
|
wide, on most bands you can have all the JT65 *and* all the JT9
|
|
|
|
|
|
activity on screen at once, available for making QSOs.
|
|
|
|
|
|
|
|
|
|
|
|
Other improvements since v1.0, r3323 include the following:
|
|
|
|
|
|
|
|
|
|
|
|
1. CAT control via DxLab Commander.
|
|
|
|
|
|
|
|
|
|
|
|
2. Improved GUI appearance, especially on Linux and OS X.
|
|
|
|
|
|
|
|
|
|
|
|
3. Compilable with Qt5 as well as Qt4.
|
|
|
|
|
|
|
|
|
|
|
|
4. Fixed occasional program crashes caused by receiving a message in
|
|
|
|
|
|
the form "call1 call2" (with no grid, report, etc.).
|
|
|
|
|
|
|
|
|
|
|
|
5. Improved handling of audio device selection in Linux.
|
|
|
|
|
|
|
|
|
|
|
|
6. Log QSO frequency, instead of dial frequency only.
|
|
|
|
|
|
|
|
|
|
|
|
7. Added Tx Power to ADIF log information.
|
|
|
|
|
|
|
|
|
|
|
|
8. Added option to retain between QSOs the Power and Comments fields
|
|
|
|
|
|
for ADIF and wsjtx logs.
|
|
|
|
|
|
|
|
|
|
|
|
9. Added optional antenna description for PSK Reporter.
|
|
|
|
|
|
|
|
|
|
|
|
10 Fixed a bug in handling of logged grid locator when none was
|
|
|
|
|
|
available on the double-clicked line.
|
|
|
|
|
|
|
|
|
|
|
|
11. Fixed a bug that caused small differences in the lengths of
|
|
|
|
|
|
transmitted symbols. This leads to improved decoding.
|
|
|
|
|
|
|
|
|
|
|
|
12. Tx message (highlighted in yellow) now includes a mode flag and
|
|
|
|
|
|
the audio offset from dial frequency.
|
|
|
|
|
|
|
|
|
|
|
|
13. Added a spinner control for Rx Freq.
|
|
|
|
|
|
|
|
|
|
|
|
14. New on-screen button "Lock Tx=Rx" locks Tx and Rx frequencies
|
|
|
|
|
|
together.
|
|
|
|
|
|
|
|
|
|
|
|
15. Allow Windows COM port number greater than 9.
|
|
|
|
|
|
|
|
|
|
|
|
16. Don't clear DxGrid when user double-clicks on a message with no
|
|
|
|
|
|
grid, if the message's Tx call is same as DxCall.
|
|
|
|
|
|
|
|
|
|
|
|
17. Double-click on yellow Tx message now sets frequency, but does
|
|
|
|
|
|
nothing else.
|
|
|
|
|
|
|
|
|
|
|
|
18. Rationalized the logic of the CAT control indicator button. Now
|
|
|
|
|
|
colored grey/green/orange/red -- see User's Guide.
|
|
|
|
|
|
|
|
|
|
|
|
19. Operating in "Split Tx" mode is optional (but with most radios is
|
|
|
|
|
|
necessary if you will transmit at more than 2.7 kHz above dial
|
|
|
|
|
|
frequency).
|
|
|
|
|
|
|
|
|
|
|
|
20. The correct TxMode label now appears on program startup.
|
|
|
|
|
|
|
|
|
|
|
|
21. "Transmitting..." message in ALL.TXT now has the correct TxMode.
|
|
|
|
|
|
|
|
|
|
|
|
22. File wsjt_status.txt includes TxMode.
|
|
|
|
|
|
|
|
|
|
|
|
23. F4 clears Az, Dist, and the Tx message boxes.
|
|
|
|
|
|
|
|
|
|
|
|
24. You can decode JT9 signals in the JT65 frequency range, and
|
|
|
|
|
|
vice-versa, by double-clicking the signal in the waterfall.
|
|
|
|
|
|
|
|
|
|
|
|
25. Better logic for enabling/disabling the TestPTT button.
|
|
|
|
|
|
|
|
|
|
|
|
26. Do not call getFreq() when the TestPTT button is clicked and
|
|
|
|
|
|
PTTmethod is via CAT control.
|
|
|
|
|
|
|
|
|
|
|
|
27. New cold-start default frequencies are set at reasonable values
|
|
|
|
|
|
for JT65. A "+2 kHz" checkbox is provided for quick setup in JT9-only
|
|
|
|
|
|
mode.
|
|
|
|
|
|
|
|
|
|
|
|
28. Default macros added as simple examples.
|
|
|
|
|
|
|
|
|
|
|
|
In case you wondered about r3482, which was posted for a few hours
|
|
|
|
|
|
only...
|
|
|
|
|
|
|
|
|
|
|
|
It was repleced by r3487 in order to fix two bugs. Revision 3487
|
|
|
|
|
|
uses more sensible logic for what to do when the "DX Grid" entry is
|
|
|
|
|
|
edited, and it fixes a bug that could prevent program restart if
|
|
|
|
|
|
you had exited the program with "+2 kHz" checked.
|
|
|
|
|
|
|
|
|

|
May 30, 2013: Version 1.0, r3323
|
|
|
|
|
|
--------------------------------
|
|
|
|
|
|
|
|
|
|
|
|
With this release of WSJT-X Version 1.0 we include a few (relatively
|
|
|
|
|
|
minor) enhancements in response to user requests, as well as some
|
|
|
|
|
|
program polishing and cleanup. Active program development will
|
|
|
|
|
|
continue, but new releases will become less frequent.
|
|
|
|
|
|
|
|
|
|
|
|
1. New option on the Setup menu: "Tx freq locked to Rx freq".
|
|
|
|
|
|
|
|
|
|
|
|
2. Double-click on a decoded "73" message now sets Tx5, rather than Tx6.
|
|
|
|
|
|
|
|
|
|
|
|
3. New keyboard shortcuts: Alt+1 through Alt+6 set the next Tx message
|
|
|
|
|
|
at the corresponding number.
|
|
|
|
|
|
|
|
|
|
|
|
4. PTT control via Ham Radio Deluxe has been imnplemented and tested.
|
|
|
|
|
|
|
|
|
|
|
|
5. "Tool Tips" are now provided for most on-screen controls.
|
|
|
|
|
|
|
|
|
|
|
|
6. Under Linux and OS X, listings of available audio devices and APIs
|
|
|
|
|
|
have been corrected.
|
|
|
|
|
|
|
|
|
|
|
|
7. Tab order among GUI controls has been cleaned up.
|
|
|
|
|
|
|
|
|
|
|
|
8. Updates to the WSJT-X User's Guide.
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
May 22, 2013: v0.99, r3297
|
|
|
|
|
|
--------------------------
|
|
|
|
|
|
|
|
|
|
|
|
1. CAT control via Ham Radio Deluxe is now available. For setup
|
|
|
|
|
|
details see item #5 at the top of page 6 of the updated WSJT-X
|
|
|
|
|
|
User's Guide.
|
|
|
|
|
|
|
|
|
|
|
|
2. Submodes JT9-5, JT8-10, JT9-30 have been de-activated. (As far as I
|
|
|
|
|
|
know, nobody was using them.) This action makes the program smaller
|
|
|
|
|
|
by some 150 MB and able to run effectively on some older computers.
|
|
|
|
|
|
|
|
|
|
|
|
3. Bizarre ordering of COM port numbers on the drop-down list has been
|
|
|
|
|
|
corrected, and suitable serial ports added to the list displayed in
|
|
|
|
|
|
Linux.
|
|
|
|
|
|
|
|
|
|
|
|
4. Gray bar between decoding periods now contains a dashed line.
|
|
|
|
|
|
|
|
|
|
|
|
5. Corrected a bug that prevented use of Setup | Configuration with
|
|
|
|
|
|
no existing wsjtx.ini file.
|
|
|
|
|
|
|
|
|
|
|
|
May 17, 2013: v0.95, r3278
|
|
|
|
|
|
--------------------------
|
|
|
|
|
|
1. Double-clicking on a decoded text line in "Band Activity" window
|
|
|
|
|
|
now copies the line into the "QSO Frequency" window if it was not
|
|
|
|
|
|
already there.
|
|
|
|
|
|
|
|
|
|
|
|
2. Option "Color highlighting in left window" removed from Setup
|
|
|
|
|
|
menu. Highlighting is now always done.
|
|
|
|
|
|
|
|
|
|
|
|
3. Positions of "QSO Frequency" and "Band Activity" windows have been
|
|
|
|
|
|
swapped.
|
|
|
|
|
|
|
|
|
|
|
|
4. F4 was restored to its previous use; F5 is now used to display
|
|
|
|
|
|
Special Mouse Commands
|
|
|
|
|
|
|
|
|
|
|
|
5. Small square between Band selector and Frequency readout was made
|
|
|
|
|
|
a control button. Orange indicates one-way CAT control from
|
|
|
|
|
|
program to radio, red indicates bi-directional control. Clicking
|
|
|
|
|
|
the orange button causes a one-time readout of dial frequency.
|
|
|
|
|
|
|
|
|
|
|
|
6. If Save=None, the last recorded file is deleted on program exit.
|
|
|
|
|
|
This prevents unwanted accumulation of files in the Save
|
|
|
|
|
|
directory.
|
|
|
|
|
|
|
|
|
|
|
|
7. Status-bar messages were re-arranged in a more logical order.
|
|
|
|
|
|
|
|
|
|
|
|
8. Tx signal report was added to wsjtx_status.txt (for JT-Alert)
|
|
|
|
|
|
|
|
|
|
|
|
9. More informative labels were placed on the "Tab 2" GUI controls.
|
|
|
|
|
|
|
|
|
|
|
|
10. Better default scaling for the "Cumulative" spectrum.
|
|
|
|
|
|
|
|
|
|
|
|
11. New algorithm for identifying JT9 signals to send to decoder,
|
|
|
|
|
|
resulting major improvements in decoder speed.
|
|
|
|
|
|
|
|
|
|
|
|
12. Bug fixes:
|
|
|
|
|
|
- Incorrect displayed frequencies for JT9-2 signals
|
|
|
|
|
|
- Infinitely repeated "Error rigOpen -1" messages
|
|
|
|
|
|
- User tries to open CAT control using busy or nonexistent serial port
|
|
|
|
|
|
|
|
|
|
|
|
13. Many updates to the User's Guide
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
May 2, 2013: v0.95, r3251
|
|
|
|
|
|
-------------------------
|
|
|
|
|
|
|
|
|
|
|
|
1. The "band change" function is executed whenever the Band combobox
|
|
|
|
|
|
is activated, even if the selected band has not changed.
|
|
|
|
|
|
|
|
|
|
|
|
2. The program does not set rig mode. That task is left to the user.
|
|
|
|
|
|
|
|
|
|
|
|
3. Time interval for polling rig frequency is now a user parameter on
|
|
|
|
|
|
the setup screen. I set mine to 1 second, which works fine with
|
|
|
|
|
|
the Kenwood TS-2000. Set it to 0 if you want no polling for
|
|
|
|
|
|
frequency (which means unidirectional CAT control from program to
|
|
|
|
|
|
radio). Choose something like 10 s for the K3.
|
|
|
|
|
|
|
|
|
|
|
|
4. Much new work on the WSJT-X User's Guide, which is approaching its
|
|
|
|
|
|
final form for Version 1.0. Please read it and tell us about
|
|
|
|
|
|
anything you find unclear or missing!
|
|
|
|
|
|
|
|
|
|
|
|
These changes address nearly all of the CAT issues found by a few
|
|
|
|
|
|
users -- those with K3, IC-746, IC-706, in particular.
|
|
|
|
|
|
|
|
|
|
|
|
One additional piece of advice when running WSJT-X in Windows: connect
|
|
|
|
|
|
and turn on the radio and any interface equipment before starting
|
|
|
|
|
|
WSJT-X, and exit the program before turning such equipment off.

April 29, 2013: v0.95, r3243
|
|
|
|
|
|
----------------------------
|
|
|
|
|
|
|
|
|
|
|
|
1. Now has bi-directionsl CAT control using direct calls to hamlib
|
|
|
|
|
|
functions. Highlights displayed dial frequency with red background
|
|
|
|
|
|
if frequency differs from nominal for the selected band by more
|
|
|
|
|
|
than 100 kHz. (Is there a more useful or logical condition to
|
|
|
|
|
|
flag?) Small red square between Band selector and Dial Frequency
|
|
|
|
|
|
display to indicate that CAT control is active. Mode is set to USB
|
|
|
|
|
|
on startup. (Note: CAT control diagnostics are presently rather
|
|
|
|
|
|
rudimentary, we're still working on this. Feedback is welcome!)
|
|
|
|
|
|
|
|
|
|
|
|
2. New controls on Setup | Configuration screen:
|
|
|
|
|
|
- RTS/DTR OFF -- needed by K2 and maybe other radios
|
|
|
|
|
|
- Data / Mic -- select CAT-control PTT type
|
|
|
|
|
|
- Test CAT Control -- try settings before returning to main screen
|
|
|
|
|
|
- Test PTT -- try settings for toggling PTT On/Off
|
|
|
|
|
|
|
|
|
|
|
|
3. Help menu now provides displays of Keyboard Shortcuts (quick access
|
|
|
|
|
|
via F3) and Special Mouse Commands (F4).
|
|
|
|
|
|
|
|
|
|
|
|
4. Option "Setup | Advanced | Allow multiple instances" enables the
|
|
|
|
|
|
use of more than one instance of WSJT-X for special applications.
|
|
|
|
|
|
(The program must be copied into and run from different
|
|
|
|
|
|
directories.)
|
|
|
|
|
|
|
|
|
|
|
|
5. No posts to PSK Reporter if band was changed during the reception
|
|
|
|
|
|
period.
|
|
|
|
|
|
|
|
|
|
|
|
6. Improved behavior of Tune button.
|
|
|
|
|
|
|
|
|
|
|
|
7. Improved inter-process communication between WSJT-X and JT-Alert-X.
|
|
|
|
|
|
|
|
|
|
|
|
8. Better interaction between "Report" spinner control and Tx messages.
|
|
|
|
|
|
|
|
|
|
|
|
9. Removed the NB checkbox and slider. (Has anyone found these useful?)
|
|
|
|
|
|
|
|
|
|
|
|
10. New buttons on main window: "Tx=Rx" sets Tx frequency to current
|
|
|
|
|
|
Rx frequency; "Rx=Tx" does the opposite.
|
|
|
|
|
|
|
|
|
|
|
|
11. Log QSO confirmation window is now "non-modal": you can keep it
|
|
|
|
|
|
open and still access controls on the main window.
|
|
|
|
|
|
|
|
|
|
|
|
12. Tab-order has been rationalized on most screens.
|
|
|
|
|
|
|
|
|
|
|
|
13. Dial frequency and mode written to file ALL.TXT.
|
|
|
|
|
|
|
|
|
|
|
|
14. Double-click on decoded line sets Tx message #3 if message has
|
|
|
|
|
|
the form "MyCall Call2 rpt".
|
|
|
|
|
|
|
|
|
|
|
|
15. Bug causing occasional, seemingly unpredictable program crashes
|
|
|
|
|
|
has been fixed.
|
|
|
|
|
|
|
|
|
|
|
|
16. The WSJT-X User's Guide is somewhat closer to being complete. User
|
|
|
|
|
|
feedback on the Guide will be most welcome. What is unclear? What
|
|
|
|
|
|
is missing?

April 17, 2013: v0.9, r3195
|
|
|
|
|
|
---------------------------
|
|
|
|
|
|
1. Sorry, the CAT control changes in r3187/3188 were a dismal failure
|
|
|
|
|
|
in many stations, and they introduced other bugs as well. This revision
|
|
|
|
|
|
goes back to uni-directional CAT control: the program can set the
|
|
|
|
|
|
radio's dial frequency and do T/R switching, but that's all. The band
|
|
|
|
|
|
setting is not reset on program startup.
|
|
|
|
|
|
|
|
|
|
|
|
2. Logic for the Tune button has been corrected.
|
|
|
|
|
|
|
|
|
|
|
|
3. For Linux compile-it-yourself enthusiasts: the interface to
|
|
|
|
|
|
PSK Reporter is now working undel Linux.
|
|
|
|
|
|
|
|
|
|
|
|
April 16, 2013: v0.9, r3188
|
|
|
|
|
|
---------------------------
|
|
|
|
|
|
|
|
|
|
|
|
1. CAT control now reads and follows changes in radio's dial
|
|
|
|
|
|
frequency. Readout gets red highlighting if radio is on wrong band.
|
|
|
|
|
|
On program restart, band is reset to the last selected band.
|
|
|
|
|
|
|
|
|
|
|
|
2. New "Tune" button generates an unmodulated carrier. Toggle button
|
|
|
|
|
|
a second time to turn Tx off.
|
|
|
|
|
|
|
|
|
|
|
|
3. Added labels at top of "Tab 2" and enlarged the text entry fields.
|
|
|
|
|
|
|
|
|
|
|
|
4. Fixed the broken logic for "Runaway Tx watchdog".
|
|
|
|
|
|
|
|
|
|
|
|
5. Fixed "Prompt me to log QSO" so that it no longer requires also
|
|
|
|
|
|
setting "ID after 73".
|
|
|
|
|
|
|
|
|
|
|
|
6. Additional changes of (eventual) interest to Linux users. Code for
|
|
|
|
|
|
sending spots to PSK Reporter now in place.

This version of WSJT-X has a number of significant changes. Please
|
|
|
|
|
|
read the following notes carefully. Also -- even if you are already
|
|
|
|
|
|
familiar with WSJT-X -- be sure to read the updated WSJT-X User's
|
|
|
|
|
|
Guide at
|
|
|
|
|
|
http://www.physics.princeton.edu/pulsar/K1JT/WSJT-X_Users_Guide.pdf ,
|
|
|
|
|
|
especially pages 3 and 4.
|
|
|
|
|
|
|
|
|
|
|
|
Changes since v0.8 r3118 include the following:
|
|
|
|
|
|
|
|
|
|
|
|
1. There are now two scrolling windows for decoded text. The left
|
|
|
|
|
|
window contains decodes only from close to the designated QSO
|
|
|
|
|
|
frequency. The right window includes signals over the full decoding
|
|
|
|
|
|
range.
|
|
|
|
|
|
|
|
|
|
|
|
2. An alternative set of controls is now available for generating and
|
|
|
|
|
|
selecting Tx messages. Some may find these more convenient to use
|
|
|
|
|
|
than the Tx1 through Tx6 message boxes.
|
|
|
|
|
|
|
|
|
|
|
|
3. A number of new user options are available on the Setup menu:
|
|
|
|
|
|
- Blank line between decoding periods (right window only)
|
|
|
|
|
|
- Clear DX Call and DX Grid after logging QSO
|
|
|
|
|
|
- Display distances in miles
|
|
|
|
|
|
- Runaway Tx watchdog
|
|
|
|
|
|
- Background colors for left window
|
|
|
|
|
|
- Double-click on decoded message sets Tx Enable
|
|
|
|
|
|
|
|
|
|
|
|
4. New or changed on-screen features
|
|
|
|
|
|
- "Tol" replaced by fMin and fMax on waterfall screen (see User's Guide)
|
|
|
|
|
|
- Spinner control for signal report
|
|
|
|
|
|
- On waterfall scale: green marker for Rx freq, red for Tx. blue
|
|
|
|
|
|
for decoding range
|
|
|
|
|
|
|
|
|
|
|
|
5. New behavior
|
|
|
|
|
|
- "CQ DX" is now treated properly when decoded line is double-clicked
|
|
|
|
|
|
- Message formate for compound callsigns (e.g., PJ4/K1ABC, G4XYZ/P)
|
|
|
|
|
|
are now handled correctly. (Some restrictions apply, and will
|
|
|
|
|
|
be spelled out in the completed User's Guide.)
|
|
|
|
|
|
- Decode button now causes a decode only at the specified Rx frequency.
|
|
|
|
|
|
- Click on waterfall spectrum sets Rx freq; double-click also invokes
|
|
|
|
|
|
decoder (as though Decode button had been clicked). CTRL-click moves
|
|
|
|
|
|
both Rx and Tx freqs.
|
|
|
|
|
|
- Amplitude at end of transmission is ramped down to prevent a final
|
|
|
|
|
|
key click.
|
|
|
|
|
|
|
|
|
|
|
|
6. The following bugs have been fixed:
|
|
|
|
|
|
- Logic error in decoder
|
|
|
|
|
|
- Certain non-standard Tx messages could cause a program crash.
|
|
|
|
|
|
- Certain (rarely used) messages did not pack/unpack correctly
|
|
|
|

|
|
|
|
|
|
--------------------------
|
|
|
|
|
|
1. Improved interface to program JT-Alert, by VK3AMA.
|
|
|
|
|
|
|
|
|
|
|
|
2. The LogQSO confirmation dialog no longer blocks the GUI updating
|
|
|
|
|
|
process.
|
|
|
|
|
|
|
|
|
|
|
|
3. A blank line with gray background separates the decoded text lines for
|
|
|
|
|
|
each new invocation of the decoder.
|
|
|
|
|
|
|
|
|
|
|
|
4. New suggested default frequencies: 5.357, 18.104, and 24.918 MHz.
|
|
|
|
|
|
Be sure to edit these entries on the 'Default Frequencies' tab of the
|
|
|
|
|
|
Setup screen. (When you have done this once, the new values will be
|
|
|
|
|
|
remembered.)
|
|
|
|
|
|
|
|
|
|
|
|
5. The LogQSO button now does nothing is the 'DX call' entry field is
|
|
|
|
|
|
blank.
|
|
|
|
|
|
|
|
|
|
|
|

|
|
|
|
|
|
|
|
|
|
|
|

|
|
|
|
|
|
|
|
3. Added an instruction on the Log QSO confirmation screen.
|
|
|
|
|
|
|
|
|
|
|
|

|
|
Edson Pereira, PY2SDR, recently became an active contributor to this
|
|
|
|
|
|
open-source project. Edson and I have been very busy over the past
|
|
|
|
|
|
few days! WSJT-X revision 3112 has many changes and new features.
|
|
|
|
|
|
|
|
|
|
|
|
1. The GUI layout has been adjusted and optimized.
|
|
|
|
|
|
|
|
|
|
|
|
2. CAT control is now operational, offering optional control of your
|
|
|
|
|
|
radio's dial frequency and T/R status. Go to the Setup | Options
|
|
|
|
|
|
window to select the necessary parameters.
|
|
|
|
|
|
|
|
|
|
|
|
3. CW ID has been implemented. You can have your ID sent after a fixed
|
|
|
|
|
|
time interval, or automatically when you transmit a "73" or free
|
|
|
|
|
|
text message.
|
|
|
|
|
|
|
|
|
|
|
|
4. Default dial frequencies are available for each band on a new tab
|
|
|
|
|
|
on the Setup | Options window. Please note: some of these
|
|
|
|
|
|
frequencies are probably wrong! You can edit them as needed.
|
|
|
|
|
|
(Please let us know if the original values are inconsistent with
|
|
|
|
|
|
actual practice on any band.)
|
|
|
|
|
|
|
|
|
|
|
|
5. Several new options appear on the Setup menu. Try them!
|
|
|
|
|
|
|
|
|
|
|
|
6. Azimuth and Distance information is displayed whenever a valid grid
|
|
|
|
|
|
locator appears in the "Dx Grid" box.
|
|
|
|
|
|
|
|
|
|
|
|
7. The decoder has again been adjusted for better compromise between
|
|
|
|
|
|
sensitivity and decoding time.
|
|
|
|
|
|
|
|
|
|
|
|
8. The User's Guide is out of date, and needs work. We hope to get to
|
|
|
|
|
|
that task soon.
|
|
|
|
|
|
|
|
|
|
|
|
9. Very important for some would-be users: WSJT-X now runs properly
|
|
|
|
|
|
under Linux. We haven't made a package yet, so for now you must
|
|
|
|
|
|
compile your own. If you don't know how, we hope to be set up
|
|
|
|
|
|
to make packages before too long.
|
|
|
|
|
|
|
|
|
|
|
|
10. If you know someone who might be interested in contributing to the
|
|
|
|
|
|
development of WSJT-X and related projects, please send him/her
|
|
|
|
|
|
our way! We're especially looking for someone interested in
|
|
|
|
|
|
producing packaged Linux distributions -- for example, *.deb or
|
|
|
|
|
|
*.rpm packages, but other programming help is also wanted.
|
|
|
|
|
|
|
|
|
|
|
|
As always: please report bugs, and don't be bashful about sending us
|
|
|
|
|
|
your feature requests!

|
|
|
|
|
|
---------------------------
|
|
|
|
|
|
1. Correct a bug that (still) allowed display of previous decodes
|
|
|
|
|
|
when nothing new was decoded.
|
|
|
|
|
|
|
|
|
|
|
|
2. Add a user confirmation screen activated when you click Log QSO.
|
|
|
|
|
|
This lets you edit or add information before it is written to the
|
|
|
|
|
|
ADIF file.
|
|
|
|
|
|
|
|
|
|
|
|
3. Tx message macros and now available. Configure them on the Setup
|
|
|
|
|
|
window. They are invoked as a pop-up menu by right-clicking on the
|
|
|
|
|
|
Tx5 message window; then select the desired message by left-clicking
|
|
|
|
|
|
on the desired message.
|
|
|
|
|
|
|
|
|
|
|
|
March 20, 2013: v0.7, r3063
|
|
|
|
|
|
---------------------------
|
|
|
|
|
|
1. Add Frequency to the generated ADIF records.
|
|
|
|
|
|
|
|
|
|
|
|
2. Correct a decoder bug that led to duplication of previous output
|
|
|
|
|
|
when nothing new was decoded.
|
|
|
|
|
|
|
|
|
|
|
|
March 19, 2013: v0.7, r3061
|
|
|
|
|
|
---------------------------
|
|
|
|
|
|
1. Allow Windows COM port numbers up to 99.
|
|
|
|
|
|
|
|
|
|
|
|
2. Replace status files wsjtx_qrg.txt and wsjtx_txcall.txt with
|
|
|
|
|
|
a single file, wsjtx_status.txt.
|
|
|
|
|
|
|
|
|
|
|
|
3. Combine wsjtx_rx.log and wsjtx_tx.log into a single file ALL.TXT.
|
|
|
|
|
|
|
|
|
|
|
|
4. "Log QSO" now writes a file in ADIF format.
|
|
|
|
|
|
|
|
|
|
|
|
5. Starting to implement popup macros for Tx message #5.
|
|
|
|
|
|
|
|
|
|
|
|
6. Big improvement in decoding speed.
|
|
|
|
|
|
|
|
|
|
|
|
*** More changes to come! Please report any problems, especially
|
|
|
|
|
|
*** with the ADIF-format log.
|
|
|
|
|
|
|
|
|
|
|
|
March 12, 2013: v0.6, r3046
|
|
|
|
|
|
---------------------------
|
|
|
|
|
|
1. Decoded calls can now be uploaded to the PSK Reporter web site.
|
|
|
|
|
|
Check the box "Enable PSK Reporter" on the Setup screen, and go to
|
|
|
|
|
|
http://pskreporter.info/pskmap.html to see the spots. Be sure to
|
|
|
|
|
|
enter your "Dial Frequency (MHz)" at lower right of the Wide Graph
|
|
|
|
|
|
window. (Rig control features are yet to come...)
|
|
|
|
|
|
|
|
|
|
|
|
2. Added some interfaces to permit use with the program JT-Alert,
|
|
|
|
|
|
by VK3AMA. Look for this capability in the near future.
|
|
|
|
|
|
|
|
|
|
|
|
March 6, 2013: v0.5, r3038
|
|
|
|
|
|
--------------------------
|
|
|
|
|
|
1. Selection of Current/Cumulative/JT9Sync for the 2d spectral display
|
|
|
|
|
|
changed to a combobox.
|
|
|
|
|
|
|
|
|
|
|
|
2. Double-click on decoded text does not change frequency settings
|
|
|
|
|
|
if first decoded call is MyCall.
|
|
|
|
|
|
|
|
|
|
|
|
March 1, 2013: v0.5, r3026
|
|
|
|
|
|
--------------------------
|
|
|
|
|
|
1. The horizontal scale of 2d spectra (e.g., the "red curve") is now
|
|
|
|
|
|
correct when the user has selected FFT Bins/Pixel > 1.
|
|
|
|
|
|
|
|
|
|
|
|
2. Double-clicking on a decoded text line now selects the second
|
|
|
|
|
|
callsign independent of exactly where one has clicked on the line.
|
|
|
|
|
|
In addition, it sets the selected frequencies (both Tx and Rx) to
|
|
|
|
|
|
the frequency of the decoded transmission.
|
|
|
|
|
|
|
|
|
|
|
|
December 11, 2012: v0.5, r2791
|
|
|
|
|
|
------------------------------
|
|
|
|
|
|
1. Messages of the form "CQ DX K1ABC" are now supported.
|
|
|
|
|
|
|
|
|
|
|
|
November 30, 2012: v0.5, r2788
|
|
|
|
|
|
------------------------------
|
|
|
|
|
|
1. A bug was introduced when support for positive signal reports was
|
|
|
|
|
|
added. It could cause a program crash when certain free-text messages
|
|
|
|
|
|
were composed for transmission. The bug has been fixed.
|
|
|
|
|
|
|
|
|
|
|
|
2. In the slower JT9 sub-modes, the UTC listed on decoded text lines
|
|
|
|
|
|
has been changed to the start time of the Rx sequence, rather than the
|
|
|
|
|
|
time of the final minute.
|
|
|
|
|
|
|
|
|
|
|
|
3. The waterfall's "Auto Zero" button had no function, and has been
|
|
|
|
|
|
removed.
|
|
|
|
|
|
|
|
|
|
|
|
4. In previous revisions the installer put a number of DLLs into
|
|
|
|
|
|
the Windows system directory, normally C:\Windows\System32. This
|
|
|
|
|
|
revision installs the DLLs to the WSJT-X installation directory.

|
|
------------------------------
|
|
|
|
|
|
1. In r2783, the companion program jt9.exe (started automatically when
|
|
|
|
|
|
you start WSJT-X) was a CPU hog for no good reason. This was an
|
|
|
|
|
|
oversight on my part, and the bug has been corrected.
|
|
|
|
|
|
|
|
|
|
|
|
2. The program should now run correctly if installed in a directory
|
|
|
|
|
|
whose name contains embedded spaces. (Under Vista and Win7, however,
|
|
|
|
|
|
it's still not a good idea to install WSJT-X into C:\Program Files,
|
|
|
|
|
|
because of restricted write permissions there.)
|
|
|
|
|
|
|
|
|
|
|
|
3. In r2783 and earlier, stopping a transmission by toggling to "Auto
|
|
|
|
|
|
OFF" would terminate Tx audio and release PTT almost simultaneously,
|
|
|
|
|
|
possibly hot-switching your T/R relay(s). This has been corrected so
|
|
|
|
|
|
that proper sequencing takes place.

November 28, 2012: v0.5, r2783
|
|
|
|
|
|
------------------------------
|
|
|
|
|
|
This revision has an unusually large number of changes relative to the
|
|
|
|
|
|
previous release, v0.4 r2746. These changes include:
|
|
|
|
|
|
|
|
|
|
|
|
1. PTT control via COM ports COM10 and higher is enabled.
|
|
|
|
|
|
|
|
|
|
|
|
2. Improved decoder performance: higher speed as well as better
|
|
|
|
|
|
chances of success. Moderate amounts of frequency drift are detected
|
|
|
|
|
|
and compensated. Computed S/N values are more reliable. Time offsets
|
|
|
|
|
|
from -2.5 to +5 s are now supported, which makes JT9 usable for EME.
|
|
|
|
|
|
(EME tests on 144 MHz have been successful, and performance on that
|
|
|
|
|
|
propagation mode appears to be good.)
|
|
|
|
|
|
|
|
|
|
|
|
3. Tx Frequency now tracks the selected QSO Frequency (unless you hold
|
|
|
|
|
|
down the CTRL key when setting QSO Frequency via mouse-clicks or the
|
|
|
|
|
|
F11/F12 keys).
|
|
|
|
|
|
|
|
|
|
|
|
4. Decoded text containing "CQ " is highlighted with green background;
|
|
|
|
|
|
text including "MyCall" is highlighted in red.
|
|
|
|
|
|
|
|
|
|
|
|
5. In previous versions, signal reports were required to be in the
|
|
|
|
|
|
range -30 to -01 dB. In v0.5 r2782 the range has been extended to -50
|
|
|
|
|
|
to +49 dB. There is backward compatibility for the range -30 to -01,
|
|
|
|
|
|
but reports in the range -50 to -31 and 0 to +49 will NOT be decoded
|
|
|
|
|
|
correctly by previous program versions. It is important to upgrade!
|
|
|
|
|
|
|
|
|
|
|
|
6. Items "Save Synced" and "Save Decoded" are now implemented.
|
|
|
|
|
|
|
|
|
|
|
|
7. UTC Date, JT9 submode, and a parameter related to the decoding
|
|
|
|
|
|
procedure are now included in file wsjtx_rx.log.
|
|
|
|
|
|
|
|
|
|
|
|
8. Editing of Tx messages (in any of the six Tx message boxes) is
|
|
|
|
|
|
complete when you hit "Tab" or "Return". The message is then parsed
|
|
|
|
|
|
and converted to the form in which it will be displayed if decoding is
|
|
|
|
|
|
successful. Free-text messages are trimmed to 13 characters and
|
|
|
|
|
|
highlighted with a pink background.
|
|
|
|
|
|
|
|
|
|
|
|
9. The most recent transmitted message is displayed in the right-most
|
|
|
|
|
|
label on the status bar. This can be useful if you have lost track of
|
|
|
|
|
|
where you were in a QSO.
|
|
|
|
|
|
|
|
|
|
|
|
10. By default, the program now starts with Monitor ON. An option on
|
|
|
|
|
|
the Setup menu allows you to select "Monitor OFF at startup".
|
|
|
|
|
|
|
|
|
|
|
|
11. Better scaling is provided for the red "JT9 Sync" curve. Note
|
|
|
|
|
|
that JT9 signals in the active sub-mode should appear in this plot as
|
|
|
|
|
|
a bump of width equal to the total signal bandwidth, with a narrow and
|
|
|
|
|
|
slightly higher bump at the left edge. The narrow bump is the
|
|
|
|
|
|
frequency of the Sync tone, which is defined as the nominal frequency
|
|
|
|
|
|
of the JT9 signal.
|
|
|
|
|
|
|
|
|
|
|
|
12. Basic QSO information is now written to file wsjt.log when you
|
|
|
|
|
|
click the "Log QSO" button.
|
|
|
|
|
|
|
|
|
|
|
|
13. The WSJT-X User's Guide has been updated.
|
|
|
|
|
|
|
|
|
|
|
|
14. Other known bugs have been fixed. There will probably be new
|
|
|
|
|
|
ones! When you find one, or if you know of any old ones that have NOT
|
|
|
|
|
|
been fixed, please send me email.

Summary of Present Status
|
|
|
|
|
|
----------------------------------------------------------------------
|
|
|
|
|
|
I believe that WSJT-X is now a stable and very usable program. Many
|
|
|
|
|
|
thousands of QSOs have been made with JT9-1, mostly at HF -- I have
|
|
|
|
|
|
made nearly 100, myself. Also a number of QSOs have also been
|
|
|
|
|
|
completed at MF, and successful tests have been made on 2m EME, etc.
|
|
|
|
|
|
A number of QSOs have also been made with JT9-2.
|
|
|
|
|
|
|
|
|
|
|
|
As far as I know the slower modes (JT9-5, JT9-10, and JT9-30) also
|
|
|
|
|
|
work correctly. (Certainly they do in my laboratory test setup.)
|
|
|
|
|
|
Most people will find these modes too slow for "everyday" use, and
|
|
|
|
|
|
they require high frequency stability. It remains to be seen whether
|
|
|
|
|
|
they will be widely used.
|
|
|
|
|
|
|
|
|
|
|
|
An alternative approach to obtaining improved sensitivity would be to
|
|
|
|
|
|
give the decoder an ability to average over several successive
|
|
|
|
|
|
transmissions. For example, the average of five JT9-1 transmissions
|
|
|
|
|
|
could reach a decoding threshold around -32 dB, only 2 dB worse than a
|
|
|
|
|
|
single JT9-5 transmission. Because of QSB, the shorter transmissions
|
|
|
|
|
|
may actually succeed in less total time. Stability requirements would
|
|
|
|
|
|
be those of JT9-1, much less stringent than those of JT9-5.
|
|
|
|
|
|
|
|
|
|
|
|
Program development is not finished, by any means. I will be grateful
|
|
|
|
|
|
for your feedback on performance issues, as well as your "wish-list"
|
|
|
|
|
|
of features to be added. As always, example recordings of files that
|
|
|
|
|
|
you think should have decoded, but did not, will be much appreciated.

November 16, 2012: v0.4, r2746
|
|
|
|
|
|
------------------------------
|
|
|
|
|
|
|
|
|
|
|
|
Changes from v0.4 r2731 include the following:
|
|
|
|
|
|
|
|
|
|
|
|
1. Valid signal reports are now generated by double-clicking on a
|
|
|
|
|
|
callsign in the decoded text window.
|
|
|
|
|
|
|
|
|
|
|
|
2. Consecutive spaces in a Tx message are now collapsed into a single
|
|
|
|
|
|
space.
|
|
|
|
|
|
|
|
|
|
|
|
3. Decoding speed is much improved, especially when strong (possibly
|
|
|
|
|
|
non-JT9) signals are present and "Tol" is set to a relatively large
|
|
|
|
|
|
value.
|
|
|
|
|
|
|
|
|
|
|
|
4. Scaling of the "JT9 Sync" plot (red curve) is more reasonable.
|
|
|
|
|
|
|
|
|
|
|
|
5. Layout of widgets on the main window has been improved.
|
|
|
|
|
|
|
|
|
|
|
|
6. Several minor bug fixes.
|
|
|
|
|
|
|
|
|
|
|
|
November 14, 2012: v0.4, r2731
|
|
|
|
|
|
------------------------------
|
|
|
|
|
|
|
|
|
|
|
|
A number of known bugs have been fixed, and the JT9 decoder is
|
|
|
|
|
|
significantly improved. Among other improvements, the program is now
|
|
|
|
|
|
much less fussy about timing issues.
|
|
|
|
|
|
|
|
|
|
|
|
November 6, 2012: v0.3, r2717
|
|
|
|
|
|
------------------------------
|
|
|
|
|
|
|
|
|
|
|
|
Changes from r2713 include the following:
|
|
|
|
|
|
|
|
|
|
|
|
1. A bug in the decoder that led to erratic behavior (failed decodes)
|
|
|
|
|
|
under certain conditions has been corrected. Decoding is now much
|
|
|
|
|
|
more reliable.
|
|
|
|
|
|
|
|
|
|
|
|
2. A valid algorithm is now used to calculate S/N values for received
|
|
|
|
|
|
JT9 signals.
|
|
|
|
|
|
|
|
|
|
|
|
3. The header format of recorded *.wav files has been corrected.
|
|
|
|
|
|
These files will now play correctly in Windows programs that expect
|
|
|
|
|
|
the standard header.
|
|
|
|
|
|
|
|
|
|
|
|
November 6, 2012: v0.2, r2713
|
|
|
|
|
|
------------------------------
|
|
|
|
|
|
|
|
|
|
|
|
Changes from r2711 include the following:
|
|
|
|
|
|
|
|
|
|
|
|
1. Updates to the Quick-Start User's Guide,
|
|
|
|
|
|
http://www.physics.princeton.edu/pulsar/K1JT/WSJT-X_Users_Guide.pdf
|
|
|
|
|
|
|
|
|
|
|
|
2. Double-click on waterfall now sets Tol to a reduced
|
|
|
|
|
|
(mode-dependent) value.
|
|
|
|
|
|
|
|
|
|
|
|
3. Tol is saved and restored on program restart.
|
|
|
|
|
|
|
|
|
|
|
|
4. A "digital gain" slider was added next to the green-bar audio level
|
|
|
|
|
|
indicator. With the slider at mid-range, the scale reads correctly in
|
|
|
|
|
|
dB above the least significant bit of 16-bit audio data.
|
|
|
|
|
|
|
|
|
|
|
|
5. There is now a test that rejects at least one type of data that is
|
|
|
|
|
|
sufficiently corrupt to cause Eddie's best friend, the message
|
|
|
|
|
|
"15P6715P67WCV".
|
|
|
|
|
|
|
|
|
|
|
|
6. Several minor tweaks to improve decoder performance.
|
|
|
|
|
|
|
|
|
|
|
|
7. The program now starts with Monitor OFF. You must click Monitor to
|
|
|
|
|
|
start accepting audio. For some types of testing, this may be an
|
|
|
|
|
|
advantage. This startup condition may be changed again, in the
|
|
|
|
|
|
future.
|
|
|
|
|
|
|
|
|
|
|
|
October 31, 2012: v0.2, r2711
|
|
|
|
|
|
-----------------------------
|
|
|
|
|
|
|
|
|
|
|
|
Three significant changes since r2706:
|
|
|
|
|
|
|
|
|
|
|
|
1. Three options are now provided on the "Decode" menu, controlling
|
|
|
|
|
|
the "depth" of the decoding process. For most purposes I suggest you
|
|
|
|
|
|
should use "Normal", but feel free to experiment with the others.
|
|
|
|
|
|
|
|
|
|
|
|
2. Decoding of multiple signals in one Rx interval has been improved.
|
|
|
|
|
|
|
|
|
|
|
|
3. Handling of strong signals has been improved.
|
|
|
|
|
|
|
|
|
|
|
|
October 309, 2012: v0.2, r2706
|
|
|
|
|
|
------------------------------
|
|
|
|
|
|
|
|
|
|
|
|
Changes since r2702 include the following:
|
|
|
|
|
|
|
|
|
|
|
|
1. The problem with "ghost" signals is fixed.
|
|
|
|
|
|
|
|
|
|
|
|
2. A problem causing very long decode times under certain
|
|
|
|
|
|
circumstances has been fixed. Please note: decode times on any recent
|
|
|
|
|
|
PC should no more than a few seconds!
|
|
|
|
|
|
|
|
|
|
|
|
3. I have re-directed the program's fatal error messages so they will
|
|
|
|
|
|
be sent to the command-prompt window from which you started the
|
|
|
|
|
|
program. Please send me full reports on any such messages you observe,
|
|
|
|
|
|
preferably with details on how to reproduce the problem.

#########################################################################
|
|
|
|
|
|
|
|
|
|
|
|
Some additional information ...
|
|
|
|
|
|
|
|
|
|
|
|
1. Yes, the JT9 modes require good stability in all system
|
|
|
|
|
|
oscillators. The present JT9 bdecoder does not attempt to track
|
|
|
|
|
|
frequency drifts. Such capability will be added, however. We have
|
|
|
|
|
|
been using digital modes for EME for nearly ten years now, at 144 MHz
|
|
|
|
|
|
and higher. There are more than 1000 WSJT users on EME, using all
|
|
|
|
|
|
kinds of rige. We have learned how to deal with reasonable rates of
|
|
|
|
|
|
drift. Surely if we can do these things at VHF, we can do them much
|
|
|
|
|
|
more easily at MF and LF.
|
|
|
|
|
|
|
|
|
|
|
|
2. If you're sure that you have seen degraded JT9 performance because
|
|
|
|
|
|
of frequency stability issues, don't just complain on the LF
|
|
|
|
|
|
reflector. Document your case and send me an example file with a
|
|
|
|
|
|
drifting JT9 signal. Making WSJT-X and JT9 better is partly YOUR
|
|
|
|
|
|
responsibility!
|
|
|
|
|
|
|
|
|
|
|
|
3. In other ways as well, test files are needed. I can make many
|
|
|
|
|
|
tests myself, but I can't foresee all the problems others will have.
|
|
|
|
|
|
That's what the "Save All" function is for! In these early tests,
|
|
|
|
|
|
always run with "Save All" checked, just in case you will want to
|
|
|
|
|
|
refer back to something that happened. You may want to send me the
|
|
|
|
|
|
file in question. You can always clean out your "Save" directory by
|
|
|
|
|
|
using "File | Delete all *.wav files in SaveDir". I need good
|
|
|
|
|
|
examples of signals that fail to decode for any unknown reason. Also
|
|
|
|
|
|
some good examples of atmospheric or other impulsive noise, for
|
|
|
|
|
|
testing the noise blanker.
|
|
|
|
|
|
|
|
|
|
|
|
4. I have added a page of "Hints for New Users" to the online WSJT-X
|
|
|
|
|
|
User's Guide,
|
|
|
|
|
|
http://www.physics.princeton.edu/pulsar/K1JT/WSJT-X_Users_Guide.pdf .
|
|
|
|
|
|
Please read it! ... and let me know if you find other operational
|
|
|
|
|
|
details of WSJT-X that need explanation. This will likely be
|
|
|
|
|
|
especially true for those not already familiar with older versions of
|
|
|
|
|
|
WSJT.
|
|
|
|
|
|
|
|
|
|
|
|
5. An operational suggestion: In many ways the different JT9 submodes
|
|
|
|
|
|
are treated as distinct modes. If you receive a JT9-x signal in a
|
|
|
|
|
|
different submode than the one you have selected, you won't decode
|
|
|
|
|
|
it. For this reason, if JT9 is to become popular we'll probably need
|
|
|
|
|
|
to choose one or two of the submodes for general use, and perhaps
|
|
|
|
|
|
assign a narrow slice of the band to each one. Note that "message
|
|
|
|
|
|
averaging" in the Rx software can make two or three JT9-2
|
|
|
|
|
|
transmissions as good as one JT9-5 transmission, with the advantage
|
|
|
|
|
|
that you will copy sooner if signals are better than required for
|
|
|
|
|
|
JT9-5. Message averaging is not yet present in the JT9 decoder... but
|
|
|
|
|
|
in future it can be. Again, we have dealt with such issues very
|
|
|
|
|
|
effectively on EME -- and can do so at MF/LF, for sure.
|
|
|
|
|
|
|
|
|
|
|
|
6. On the topic of CW, Beacons, WSPR, JT9, etc. I really don't
|
|
|
|
|
|
understand what all the fuss is about. Surely there is room for
|
|
|
|
|
|
everybody? Maybe I'm just too new here to understand? (Mal, is this
|
|
|
|
|
|
mostly just a matter of "Mal being Mal"???)
|
|
|
|
|
|
|
|
|
|
|
|
On the HF bands, the WSPR sub-band is just 200 Hz wide. If we did the
|
|
|
|
|
|
same on 630 m, the WSPR sub-band would take up less than 3% of the 7
|
|
|
|
|
|
kHz band. If that's too much, we could cut it in half, or even less,
|
|
|
|
|
|
and still have enough WSPR space. Moreover, a "slow WSPR", if
|
|
|
|
|
|
warranted, would require even less bandwidth. Similar comments apply
|
|
|
|
|
|
to JT9. The bandwidth of JT9 signals is significantly less than that
|
|
|
|
|
|
of CW, for comparable information rates. There should be enough
|
|
|
|
|
|
spectrum for both, even in our narrow MF and LF bands.
|
|
|
|
|
|
|
|
|
|
|
|
7. As for performance comparisons between JT9 and WSPR: WSPR is a
|
|
|
|
|
|
mature program, and its decoder has been optimized and tweaked over a
|
|
|
|

October 29, 2012: v0.2, r2702
|
|
|
|
|
|
-----------------------------
|
|
|
|
|
|
Changes since version 0.1, r2696 include the following:
|
|
|
|
|
|
|
|
|
|
|
|
1. Sample rate for audio output has been changed from 12000 to 48000
|
|
|
|
|
|
Hz. Tx audio may now be generated at any frequency from 500 to 20000
|
|
|
|
|
|
Hz.
|
|
|
|
|
|
|
|
|
|
|
|
2. The Decoder now tries to decode all synchronizable signals in the
|
|
|
|
|
|
"green zone", that is, within "Tol" Hz of the selected QSO
|
|
|
|
|
|
frequency. (Before, by default it decoded only the signal producing
|
|
|
|
|
|
the highest "sync" value. Other signals could be decoded by manually
|
|
|
|
|
|
setting the QSO frequency and reducing Tol as needed.)
|
|
|
|
|
|
|
|
|
|
|
|
3. The user's selected QSO Frequency is now saved and restored on
|
|
|
|
|
|
program restart.
|
|
|
|
|
|
|
|
|
|
|
|
4. The problem with re-initialization after changing sub-modes has
|
|
|
|
|
|
been fixed.
|
|
|
|
|
|
|
|
|
|
|
|
5. The problem (for some users) of not releasing PTT after end of a
|
|
|
|
|
|
transmission has been fixed.
|
|
|
|
|
|
|
|
|
|
|
|
6. The program now writes a log of all decodes to a file wsjtx_rx.log
|
|
|
|
|
|
in the wsjtx directory.
|
|
|
