Release: WSJT-X 2.0
|
|
December 10, 2018
|
|
-----------------------
|
|
|
|
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
|
|
- Faster entry and correct scrolling for Fox/Contest log
|
|
- Add contest exchanges and contest type to UDP logged QSO message
|
|
- Fix a bug that suppressed decodes with negative DT.
|
|
- AK and HI are DXCCs, not states, for RTTY Roundup
|
|
- 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...)
|
|
- Update cty.dat
|
|
|
|
Release: WSJT-X 2.0-rc5
|
|
November 26, 2018
|
|
-----------------------
|
|
|
|
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
|
|
- Move Fox log Reset action to Fox log window context menu
|
|
- 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.
|
|

|
nonstandard call.
|
|
|
|
- Fixed a bug that generated incorrect MSK144 tones for certain

|
Release: WSJT-X Version 1.8.0
|
|
October 27, 2017
|
|
-----------------------------
|
|
|
|
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
|
|
---------------------------------
|
|
|
|
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.
|
|
|
|
- Restore printing of MSK144 decode quality information.
|
|
|
|
- Display Echo Graph automatically when Echo mode is started.
|
|
|
|
- Fix a bug that prevented double-click on a JT65 EME-style "OOO"
|
|
message from populating the Tx message boxes.
|
|
|
|
- Fixed behavior with double-click on 'CQ <AA-ZZ> <call> <grid>.'
|
|
|
|
- Update the "blank line" divider with band ID at 4*TRperiod/5.
|
|
|
|
- Fix cty.dat lookups that were not honouring exact match flags
|
|
|
|
- Add some further Copyright protections.
|
|
|
|
- Fix a bug involving "firstcall contains mycall" but not equal to mycall.
|
|
|
|
- Fix an issue with editing IARU regions in the working frequencies table.
|
|

Release: WSJT-X Version 1.8.0-rc2
|
|
September 2, 2017
|
|
---------------------------------
|
|
|
|
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*.
|
|

|
-----------------------------
|
|
|
|
NEW FEATURES IN WSJT-X Version 1.8.0
|
|
------------------------------------
|
|
|
|
1. New mode called FT8: sensitivity down to -20 dB on the AWGN
|
|
channel; QSOs 4 times faster than JT65 or JT9; auto-sequencing
|
|
includes an option to respond automatically to first decoded
|
|
reply to your CQ.
|
|
|
|
2. New mode for accurate Frequency Calibration of your radio.
|
|
|
|
3. Improved performance of decoders for JT65, QRA64, and MSK144.
|
|
MSK144 includes facilities for amplitide and phase equalization

|
and an "SWL" mode for short-format messages.
|
|
|
|
4. Options to minimize screen space used by Main and Wide Graph
|
|
windows.
|
|
|
|
5. Enhanced management scheme for table of operating frequencies, and
|
|
a new set of default frequencies specific to the three IARU
|
|
Regions.
|
|
|
|
6. Improved CAT control for many rigs, including those controlled
|
|
through Commander or OmniRig.
|
|
|
|
7. New keyboard shortcuts to set "Tx even/1st" ON or OFF.
|
|
|
|
8. A number of (mostly minor) bug fixes and tweaks to the user
|
|
interface. For example: new behavior for the audio level slider;
|
|
correctly logged QSO start times in certain situations; correct
|
|
control of FT-891/991 and some other radios via rigctld.
|
|
|
|
At the time of the v1.8.0-rc1 release the following tasks are yet to
|
|
be completed:
|
|
|
|
1. Updates to WSJT-X User Guide.
|
|
2. Sample files for FT8.
|
|
3. Enhanced decoding using AP ("a priori") information.
|
|
4. Signal subtraction and multi-pass decoding.
|
|
5. Option to Auto-respond to the weakest responder to your CQ.

Brief Description of the FT8 Protocol
|
|
-------------------------------------
|
|
|
|
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!
