for message type and 74 for user information. Any message type that
|
||||
uses fewer than 74 information bits can assign the remaining bits to
|
||||
define message subtypes. For example, Type i3=0 uses 71 information
|
||||
bits and the remaining 3 bits, here called n3, define 8 possible
|
||||
subtypes.

New Features in WSJT-X 2.0
|
||||
September 17, 2018
|
||||
--------------------------
|
||||
|
||||
This document is an update to the white paper "Plans for WSJT-X
|
||||
Version 2.0" that was publicly distributed on July 26, 2018. It
|
||||
describes the most important enhancements in WSJT-X 2.0 relative to
|
||||
version 1.9.1.
|
||||
|
||||
A majority of new program features involve the FT8 and MSK144
|
||||
protocols. Both modes have been upgraded to use use 77-bit
|
||||
information payloads rather than the 75 bits of the older FT8 protocol
|
||||
or 72 bits of JT4, JT9, JT65, MSK144, and QRA64. Cyclic redundancy
|
||||
checks (CRCs) that protect against false decodes have been increased
|
||||
from 12 to 14 bits (FT8) and from 8 to 13 bits (MSK144). These
|
||||
changes bring many benefits, including support of structured messages
|
||||
optimized for the following special types of QSOs and exchanged
|
||||
information:
|
||||
|
||||
1. NA VHF Contest operation with full and transparent support of grid
|
||||
locators and "/R" (Rover) callsigns
|
||||
|
||||
2. EU VHF Contest operation with the exchange of 6-digit locators, QSO
|
||||
serial numbers, and "/P" (portable) callsigns
|
||||
|
||||
3. ARRL Field Day operation with standard Field Day exchanges such as
|
||||
"6A SNJ"
|
||||
|
||||
4. ARRL RTTY Roundup operation with standard contest exchanges such as
|
||||
"579 NJ" or "559 0071"
|
||||
|
||||
5. Compound and nonstandard callsigns (up tp 11 characters); no need
|
||||
for distinctions about "Type 1" or "Type 2" prefixes/suffixes
|
||||
|
||||
6. A special "telemetry" message format for exchange of arbitrary
|
||||
information up to 71 bits
|
||||
|
||||
7. All features of FT8 DXpedition mode, as in WSJT-X v1.9.1
|
||||
|
||||
Enhancements to the FT8 decoder ensure that in most situations
|
||||
decoding sensitivity is slightly better than for the old protocol.
|
||||
Symbol rates and occupied bandwidths are the same as before, and
|
||||
false-decode rates are significantly lower. The decoding threshold
|
||||
for MSK144 is a fraction of a dB higher than before, owing to the
|
||||
slightly larger message payload and higher code rate.
|
||||
|
||||
OTHER PROGRAM ENHANCEMENTS: WSJT-X 2.0 has several other new features
|
||||
and capabilities. The WSPR decoder has significantly better
|
||||
sensitivity, by about 1 dB. Color highlighting of decoded messages
|
||||
provides worked-before status for callsigns, grid locators, and DXCC
|
||||
entities on a "by band" basis. Color highlighting can also identify
|
||||
stations that have (or have not) uploaded their logs to "Logbook of
|
||||
the World" (LoTW) within the past year. (Recent information from LoTW
|
||||
for this purpose can be downloaded from the ARRL web site.)
|
||||
|
||||
WSJT-X 2.0 introduces no significant changes to any of the modes JT4,
|
||||
JT9, JT65, QRA64, ISCAT, Echo, or FreqCal.
|
||||
|
||||
IMPORTANT: For the convenience of beta-testers, the first and second
|
||||
release candidates -- releases with "-rc1" or "-rc2" in their names --
|
||||
will have Rx and Tx capability for both the new FT8 protocol and the
|
||||
older one. Starting with the third release candidate ("-rc3"), and in
|
||||
the general-availability full release of WSJT-X 2.0, only the new
|
||||
protocol will be supported. In contrast, the new MSK144 protocol
|
||||
replaces the old one from the outset, without backward compatibility.
|
||||
To minimize on-the-air confusion, it's important that users be aware
|
||||
of these distinctions and the schedule for release of WSJT-X 2.0, as
|
||||
detailed below.
|
||||
|
||||
MESSAGE FORMATS: The following table shows examples of message formats
|
||||
supported by the new FT8 and MSK144 protocols. Parameters i3 and n3
|
||||
(shown in the first column) are used in the software to define major
|
||||
and minor 77-bit message types.

In the above list, callsigns enclosed in angle brackets (e.g.,
|
||||
<PJ4/K1ABC>, <YW18FIFA>) are transmitted as hash codes. They will be
|
||||
displayed correctly by receiving stations that have copied the full
|
||||
callsign without brackets in a previous transmissiion. Otherwise the
|
||||
receiving software will display <...>. Hash collisions are possible
|
||||
but should be rare, and extremely rare within a particular QSO.
|
||||
|
||||
Some minimal message sequences that take advantage of the new 77-bit
|
||||
formats are illustrated below. Model QSOs 1 and 2 are the same as
|
||||
those used by the old FT8 and MSK144 protocols, and QSO number 3 is
|

the same as the existing FT8 DXpedition Mode. Model QSOs 4 through 9

were not possible with the old protocols.

RELEASE SCHEDULE: Candidate releases of WSJT-X 2.0 will have built-in
|
||||
expiration dates after which they cannot be used. Target dates for
|
||||
planned releases are as follows:
|
||||
|
||||
September 17: -rc1 (expires Oct 31)
|
||||
October 15: -rc2 (expires Nov 30)
|
||||
November 12: -rc3 (expires Dec 31)
|
||||
December 10: GA Full release of WSJT-X 2.0
|
||||
|
||||
WSJT-X 2.0-rc1 provides the first chance for beta testers to use the
|
||||
new 77-bit messages. It supports the old (v1.9.1) FT8 protocol as
|
||||
well as the new message types illustrated above. To avoid QRMing
|
||||
legacy FT8 users with incompatible messages they can't decode, and to
|
||||
help concentrate testing activity into a few sub-bands, we recommend
|
||||
using the new FT8 capabilities on the 40- or 20-meter bands at dial
|
||||
frequencies 7.078 or 14.078 MHz. These frequencies are offered as FT8
|
||||
alternatives on the drop-down frequency-selection control on the main
|
||||

The new MSK144 is fully functional for QSOs between any two stations
|
||||
using a WSJT-X v2.0 release. MSK144 is not backward compatible with
|
||||
earlier program versions. Therefore during the testing period,
|
||||
approximately Sept 17 through December 10, we recommend using the new
|
||||
MSK144 capabilities on 50.380 MHz (IARU Region 1) or 50.280 (Regions 2
|
||||
and 3). By specific arrangement, or as soon as most regular users
|
||||
have upgraded to a v2.0 release, MSK144 activity can be moved back to
|
||||
50.360 (Region 1) or 50.260 (Regions 2 and 3).
|
||||
|
||||
By design, our proposed release schedule will make WSJT-X 2.0 usable
|
||||
for all relevant ARRL operating events and Eurpoean VHF contests after
|
||||
January 1, 2019.

To Do for FT8++
|
||||
---------------
|
||||
|
||||
The following list is for informtion and general guidance. Everything
|
||||
is subject to change, and not all ideas are necessarily good ones!
|
||||
|
||||
1. Nomenclature and parameters for message types
|
||||
- Old-style = classic 72-bit JT-style source-encoding
|
||||
FT8: (174,87) code: 72-bit info, i3bit, CRC12, isync=1
|
||||
MSK144: (128,80) code: 72-bit info, CRC8
|
||||
- New-style
|
||||
FT8: (174,91) code: 74+3+14, sync uses isync=2
|
||||
MSK144: (128,90) code: 74+3+13
|
||||
|
||||
2. (K1JT) For backward compatibility (good for, say, 6 months only?),
|
||||
by default we'll generate old-style messages where possible, new-style
|
||||
messages where they are needed. We'll decode both old and new types.
|
||||
|
||||
3. (K1JT -- DONE) Two new checkboxes on Advanced tab to enable 77-bit
|
||||
messages:
|
||||
- "Always generate new-style (77-bit) messages."
|
||||
- "Decode only 77-bit messages
|
||||
|
||||
4. (K9AN -- MOSTLY DONE) New-style messages can be as long as 37
|
||||
characters. We'll need to allow for that in a number of places.
|
||||
|
||||
5. (K9AN -- DONE) Subroutine genft8() will need to parse the message to be
|
||||
transmitted, determine the effective message type i3 and possibly
|
||||
subtype, n3. It will then generate itone, calling genft8_174_91(() if
|
||||
needed.
|
||||
|
||||
6. (K1JT) Code to generate the user-readable messages for each
|
||||
specialized type of operating, e.g., NA VHF contest, EU VHF contest,
|
||||
ARRL Field Day, ARRL RTTY Roundup, use of nonstandard calls.
|
||||
|
||||
7. (??) Code to do the necessary auto-sequencing for each specialized
|
||||
type of operating.
|
||||
|
||||
8. (K9AN -- MOSTLY DONE) What's needed for MSK144 with LDPC(128,90) ?
|
||||
Still need to work on Sh messages. How will genmsk_128_90 know when to
|
||||
generate a Sh message?
|
||||
|
||||
9. (K9AN) Work on the implementation of AP decoding. For which message types
|
||||
should AP be implemented? For each message type/QSO state that will use
|
||||
AP decoding, need to create an AP decoding table that defines the number and
|
||||
type of AP decoding passes.
|
||||
|
||||
==========================================================================
|
||||
The following are just ideas:
|
||||
|
||||
- Options to sort/filter decoded signals
|
||||
|
||||
- New Fox message type using constant-envelope waveform and higher
|
||||
symbol rate to accommodate multiple simultaneous QSOs. RR73 sent to
|
||||
0-5 calls, report sent to 0-5 calls. Decoding uses AP for missing
|
||||
calls, thereby effectively making lower-rate codes when not all
|
||||
slots are used.
|
||||
|
||||
- Hound should send spots of Fox to PSK Reporter.

Plans for WSJT-X Version 2.0
|
||||
----------------------------
|
||||
|
||||
This white paper describes a number of important enhancements planned
|
||||
for WSJT-X Version 2.0. Most of them involve the FT8 and MSK144
|
||||
protocols, which will be upgraded to use use 77-bit information
|
||||
payloads rather than the present 72 or 75 bits. This modest increase
|
||||
in information content will make possible new message types that
|
||||
support the following special types of QSOs and exchanged information:
|
||||
|
||||
1. NA VHF Contest operation with full and transparent support of grid
|
||||
locators and "/R" (Rover) callsigns
|
||||
|
||||
2. EU VHF Contest operation with the exchange of 6-digit locators, QSO
|
||||
serial numbers, and "/P" (portable) callsigns
|
||||
|
||||
3. ARRL Field Day operation with standard Field Day exchanges
|
||||
|
||||
4. ARRL RTTY Roundup operation with standard contest exchanges
|
||||
|
||||
5. Better and more user-friendly support for compound and nonstandard
|
||||
callsigns
|
||||
|
||||
6. A special "telemetry" message format for exchange of arbitrary
|
||||
information (up to 71 bits)
|
||||
|
||||
Decoding sensitivity for the new messages will be essentially the same
|
||||
as for the FT8 and MSK144 modes presently in WSJT-X v1.9.1. The
|
||||
existing FT8 DXpedition mode will still be supported, and a more
|
||||
powerful DXpedition mode may be offered as well.
|
||||
|
||||
In this document we'll call the new FT8 protocol "FT8+". It will be a
|
||||
superset of the FT8 implemented in v1.9.1, providing at least
|
||||
temporary compatibility and inter-operability with older program
|
||||
versions. We may decide to remove support for old-style 72- and
|
||||
75-bit messages after a specified switchover interval.
|
||||
|
||||
In contrast, the new MSK144 protocol will replace the old one without
|
||||
backward compatibility. We believe the smaller and more specialized
|
||||
group of MSK144 users will upgrade quickly and not find this
|
||||
restriction to be a problem.
|
||||
|
||||
Here are some examples of message formats that will be supported by
|
||||
FT8+ and MSK144 in WSJT-X v2.0. The list is not exhaustive.
|
||||
Parameters i3 and n3 (shown in column 1) are used in the software to
|
||||
define major and minor 77-bit message types.

To minimize confusion that's likely to arise during a switchover from
|
||||
v1.9.1 to v2.0, we propose to follow a well advertised schedule:
|
||||
|
||||
"RC1 Date" -- perhaps as early as September 15, 2018?
|
||||
-------------------------------------------------------
|
||||
|
||||
This will be the first chance for beta testers to try WSJT-X using the
|
||||
77-bit messages. We may restrict this opportunity to specific
|
||||
volunteer testers, and we'll probably include an "upgrade by
|
||||
xxxx_date" message to remind people that they are using a release
|
||||
intended only for testing.
|
||||
|
||||
FT8+ will support the old (v1.9.1) protocol as well as the new message
|
||||
types outlined above. To avoid QRMing legacy FT8 users with messages
|
||||
they can't decode, we'll recommend testing FT8+ on frequencies
|
||||
formerly used for JT9.
|
||||
|
||||
MSK144 will be fully functional between any two stations using the RC1
|
||||
software, but it will not be backward compatible with earlier program
|
||||
versions.
|
||||
|
||||
"RC2, RC3,... Date" -- perhaps in October?
|
||||
--------------------------------------------
|
||||
|
||||
As needed, depending on results of testing.
|
||||
|
||||
GA Release Date -- perhaps in November?
|
||||
---------------------------------------------
|
||||
|
||||
Official General Availability release of WSJT-X v2.0.0. The original
|
||||
MSK144 protocol will be declared obsolete.
|
||||
|
||||
|
||||
For reference: Dates of relevant upcoming ARRL contests
|
||||
-------------------------------------------------------
|
||||
VHF QSO Party: September 8-10, 2018
|
||||
RTTY Roundup: January 5-6, 2019
|
||||
VHF SS: January 19-21, 2019
|
||||
|
||||
Our proposed schedule should make WSJT-X Version 2.0 usable for
|
||||
relevant ARRL operating events in 2019.

IMPORTANT - IMPORTANT - IMPORTANT - IMPORTANT - IMPORTANT - IMPORTANT
|
||||
|
||||
Third-party individuals (i.e., others not part of the WSJT development
|
||||
team) have been compiling WSJT-X from the open source code and making
|
||||
unauthorized "releases" of their builds. I do NOT reccommend use of
|
||||
unauthorized builds on the air. If a program revision has been released
|
||||
in an official way, you will see it listed here.
|
||||
|
||||
If you operate with an unauthorized "rXXXX" code revisions in our
|
||||
experimental code branch you have no idea what you've got. Quite
|
||||
possibly, the program was built from an intermediate temporary "save"
|
||||
of various files, and was not even supposed to produce a usable
|
||||
program. Your observetions about what works or does not work are then
|
||||
worse than useless -- they waste your time and ours.
|
||||
|
||||
So please, PLEASE, *PLEASE*: use *authorized*, "released* revisions
|
||||
of this still-in-development software, like the revisions described here.
|
||||
|
||||
*ALSO:* If you choose to try an experimental release of JTMSK, please
|
||||
accept the responsibility of reporting on your results. You can send
|
||||
reports to the "wsjtgroup" reflector, wsjtgroup@yahoogroups.com, or
|
||||
email them directly to me. All suggestions for improvements are
|
||||
welcome!
|
||||
|
||||
Bug reports should include details on how to reproduce the undesirable
|
||||
program behavior. Reports on decoding performance are especially
|
||||
useful when accompanied by example *.wav files with signals that
|
||||
you think should have decoded, but did not.

New alpha release of experimental WSJT-X v1.6.1, r5910
|
||||
------------------------------------------------------
|
||||
Changes since revision 5889 include the following:
|
||||
|
||||
1. Improved behavior for auto-QSY with "CQ nnn ..." feature. (May not
|
||||
be exactly correct, yet, for all radios. Please report if you find
|
||||
problems with your rig.)
|
||||
|
||||
2. Allow optional use of Wide Graph in fast modes.
|
||||
|
||||
3. Add UTC labels to Fast Graph spectrograms.
|
||||
|
||||
4. Display correct DXCC entiry for "CQ nnn ..." messages.
|
||||
|
||||
5. Implement "Save Decoded" for fast modes.
|
||||
|
||||
6. Select Tx6 when "CQ Rx nnn" is enabled.
|
||||
|
||||
7. Fix bug in setting of TRperiod after switch to ISCAT mode.
|
||||
|
||||
8. Display proper symbol '&' in Tx messages in JTMSK mode.

|

|
||||
New alpha release of experimental WSJT-X v1.6.1, r5889
|
||||
------------------------------------------------------
|
||||
|
||||
A principal new feature in this release is designed to promote the use
|
||||
of an agreed "calling frequency" for transmissions of the form
|
||||
|
||||
CQ 265 K1ABC FN42
|
||||
|
||||
signifying that K1ABC will listen for replies on 50.265 (or 144.265,
|
||||
or whatever) and will complete the QSO there. The feature uses the
|
||||
rig-control features of WSJT-X to handle the necessary frequency
|
||||
switching.
|
||||
|
||||
##########################################################################
|
||||
Changes since revision 5865 include the following:
|
||||
|
||||
1. New features that allow automatic rig control when you transmit or
|
||||
respond to messages of the form "CQ 265 K1ABC FN42" on an agreed
|
||||
calling frequency. This feature should be especially useful for
|
||||
meteor scatter.
|
||||
|
||||
2. Yellow-highlighted "Tx" messages in the right text window are now
|
||||
properly labeled with 6-digit UTC (hhmmss) in all fast modes.
|
||||
|
||||
3. Fixed a bug (introduced in r5865) that inhibited transmitting in
|
||||
JT4 mode.
|
||||
|
||||
4. Fixed a bug that caused Wide Graph to continue issuing green
|
||||
separator lines at short (e.g. 15 s) intervals after you have switched
|
||||
to a slow mode.
|
||||
|
||||
5. Fixed several more GUI appearance bugs associated with changing
|
||||
modes or submodes.
|
||||
|
||||
6. Fixed a bug in which double-clicking on the Fast Graph could cause
|
||||
program crashes.
|
||||
|
||||
7. Fixed a bug that sometimes caused "high tones" to be emitted in
|
||||
JTMSK mode.
|
||||
|
||||
#######################################################################
|
||||
Here's a brief description of how to use the "CQ nnn ..." features.
|
||||
|
||||
1. On program startup, go to the Settings | General tab and tick the
|
||||
box labeled 'Rx frequency offset with "CQ nnn ..."'
|
||||
|
||||
2. Select JTMSK mode and 50.280 (or your some other agreed calling
|
||||
frequency) from the drop-down band menu. Remember that this menu is
|
||||
not pre-populated with preferred frequencies for all modes on all
|
||||
bands. Use Settings | Frequencies to add your desired modes and
|
||||
frequencies to the list.
|
||||
|
||||
3. Tick the unlabeled checkbox just under the "Report: spinner to
|
||||
activate the "CQ Rx nnn" spinner. Set this control to your desired
|
||||
QSO frequency in kHz above the nominal band edge. On 6 meters, for
|
||||
example, "265" means "50.265".
|
||||
|
||||
4. Your transceiver dial frequency should now show 50.265. Changes to
|
||||
the "CQ Rx nnn" spinner value should be reflected immediately in the
|
||||
transceiver dial frequency, the displayed value on the WSJT-X main
|
||||
screen, and in Tx message #6, the "CQ nnn... " message.
|
||||
|
||||
5. When you transmit the Tx6 message, the Tx frequency will be set at
|
||||
the calling frequency. Otherwise (when receiving, or when
|
||||
transmitting any of the messages Tx1 through Tx5) the offset frequency
|
||||
(50.265 in my example) will be used.
|
||||
|
||||
6. If you double-click on a received "CQ nnn ..." message on the
|
||||
calling frequency, your rig will QSY to specified response frequency,
|
||||
e.g. 50.265, for both Rx and Tx.
|
||||
|
||||
7. To go back to listening on the calling frequency, uncheck the box
|
||||
that activated the "CQ Rx nnn" spinner.
|
||||
|
||||
#######################################################################
|
||||
|
||||
Fair warning: I have not yet tested all possible combinations of
|
||||
"Split Operation" configuration (i.e., "None", "Rig", and "Fake it").
|
||||
If you normally use Split operation, that should be OK for the "CQ
|
||||
nnn ..." feature.
|
||||
|
||||
|
||||
As always, please report any bugs that you find in r5889, including
|
||||
pertinent details on your settings and the exact series of steps
|
||||
required to reproduce the bug.

New alpha release of experimental WSJT-X v1.6.1, r5865
|
||||
------------------------------------------------------
|
||||
|
||||
This alpha release of WSJT-X includes major improvements to the JTMSK
|
||||
decoder. Changes since revision 5823 include the following:
|
||||
|
||||
1. On-screen controls labeled "Rx nnnn Hz" and "F Tol" (Rx frequency
|
||||
and tolerance) now function as expected in JTMSK mode. The frequency
|
||||
search range can be up to 500 Hz, but note that sensitivity is
|
||||
necessarily reduced for signals off frequency by more than about 250
|
||||
Hz. Normally you should leave Rx Freq set at 1500 Hz; suitable values
|
||||
for F Tol are 100 to 500 Hz.
|
||||
|
||||
2. The JTMSK decoder now makes good use of strong, short pings (as
|
||||
short as 0.1 s) as well as weak pings several times longer.
|
||||
|
||||
3. Improved calculation of S/N and frequency of decoded signals.
|
||||
|
||||
4. Unified appearance of window titles on all non-modal windows.
|
||||
|
||||
5. CW ID is disabled (for now, at least) when operating in any of the
|
||||
WSJT fast modes.
|
||||
|
||||
6. In WSPR mode, display of "Receiving ... <band>" messages is
|
||||
disabled when band-hopping is not in use.
|
||||
|
||||
7. Fixed several bugs affecting status and visibility of certain
|
||||
on-screen controls after changes in operating mode.
|
||||
|
||||
8. Fixed a bug allowing display of duplicate decodes for the same
|
||||
signal.
|
||||
|
||||
9. Fixed a bug preventing compilation on 64-bit systems, and cleaned
|
||||
up some harmless compiler warnings.

Summary Description of JTMSK Protocol
|
||||
|
||||
JTMSK uses the same standard message structure as slow modes JT4, JT9,
|
||||
and JT65. User information is "source encoded" to 72 bits. A 15-bit
|
||||
CRC is appended and a convolutional code with constraint length K=13
|
||||
and rate r=1/2 is applied, making a total of (72+15+12)*2 = 198
|
||||
information bits. Three copies of the "Barker-11" code and three
|
||||
even-parity bits are added for synchronization, making a total of
|
||||
198+33+3 = 234 channel symbols. Modulation uses a constant-envelope,
|
||||
continuous-phase "minimum-shift keying" (MSK) waveform, with tone
|
||||
frequencies of 1000 and 2000 Hz.

New release of experimental WSJT-X v1.6.1, r5823

|
||||
This experimental version of WSJT-X introduces a new fast mode called
|
||||
JTMSK. The letters MS, of course, imply meteor scatter; the three
|
||||
letters MSK mean "Minimum Shift Keying", the modulation scheme used in
|
||||
this mode.
|
||||
|
||||
Revision 5823 also includes a number of (mostly minor) bug fixes
|
||||
relative to r5789.
|
||||
|
||||
IMPORTANT: If you choose to try JTMSK, please accept the
|
||||
responsibility of reporting on your results. You can send reports to
|
||||
the "wsjtgroup" reflector, wsjtgroup@yahoogroups.com or email them
|
||||
directly to me. All suggestions for improvements are welcome! Bug
|
||||
reports should include details on how to reproduce the undesirable
|
||||
program behavior.
|
||||
|
||||
The present JTMSK decoder has been optimized for short pings. It does
|
||||
not yet do a wide search for proper frequency alignment; you and your
|
||||
QSO partner need to be "on frequency" to within +/- 100 Hz or better.
|
||||
The decoder does not (yet) attempt to make optimal use of weak, slowly
|
||||
varying signals. These and other characteristics may be improved in
|
||||
coming revisions.
|
||||
|
||||
KNOWN BUG: At present you should use T/R sequence lengths 15 s in
|
||||
JTMSK mode. If you have a program crash, open Windows Task Manager,
|
||||
select the "Processes" tab, right-click on wsjtx.exe, and select "End
|
||||
Process Tree". Then restart the program.
|
||||
|
||||
I view JTMSK as a candidate for replacing both FSK441 and JTMS for all
|
||||
meteor scatter work. JTMSK has the major advantage of including
|
||||
strong forward error correction (FEC), similar in usage to the schemes
|
||||
used for many years in JT4, JT9, and JT65. The structure of user
|
||||
messages and the format of minimal QSOs is also identical to those
|
||||
other modes. But JTMSK is very fast, transmitting its full encoded
|
||||
message content in 0.117 s, in a 2 kHz bandwidth. JTMSK therefore
|
||||
makes much better use of short pings than (for example) JT9H can do.
|
||||
|
||||
The Tx waveform of JTMSK has been carefully designed to have a number
|
||||
of desirable features. All messages are exactly the same length: 72
|
||||
bits of user information are followed by a 15-bit CRC and encoded into
|
||||
198 channel bits with a convolutional code (constraint length K=13,
|
||||
rate r=1/2). Three sequences of the "Barker-11" code are added, along
|
||||
with three parity bits, making a total of 234 channel bits in each
|
||||
message. The MSK symbols for these bits are transmitted at 2000 baud,
|
||||
and the full encoded message is repeated every 117 ms.
|
||||
|
||||
A summary description of modulation parameters for all WSJT(-X) modes

||||

|
||||
---------------
|
||||
|
||||
Since its origin in the dark ages (ca. 2001) WSJT has supported "fast"
|
||||
modes (designed for meteor scatter, etc.) and "slow" modes (optimized
|
||||
for EME and other weak-signal propagation types). The most recent new
|
||||
mode, JT9, now has *both* fast and slow submodes.
|
||||
|
||||
JT9A (the "original" JT9) is like JT65 and JT4: its T/R sequences are
|
||||
one minute long, and its primary goal is best possible sensitivity for
|
||||
very weak, approximately steady signals. The new experimental JT9
|
||||
submodes use the same message structure, encoding, and modulation type
|
||||
(9-tone FSK) as JT9A, but wider tone spacing and (optionally) faster
|
||||
keying rates.
|
||||
|
||||
You can download an experimental version of WSJT-X (v1.6.1, r5779) here:
|
||||
http://physics.princeton.edu/pulsar/K1JT/wsjtx-1.6.1-r5779-win32.exe
|
||||
|
||||
The fast submodes currently being tested, JT9E - JT9H, have been found
|
||||
highly effective for meteors and ionoscatter propagation on 6 and 10
|
||||
meters. Sensitivity is similar to ISCAT, or slightly better.
|
||||
Decoding is much more reliable, because the JT9 protocol includes
|
||||
strong forward error correction. Decoding results are like those for
|
||||
all the WSJT "slow" modes: you should see messages exactly as they
|
||||
were transmitted, or nothing at all. A potential side benefit is
|
||||
automatic reporting of decodes to PSKreporter.
|
||||
|
||||
For details on the modulation parameters of the JT9 submodes, see the
|
||||
table posted at
|
||||
http://physics.princeton.edu/pulsar/K1JT/wsjt_modes.txt.
|
||||
|
||||
WSJT-X v1.6.1 r5779 has the following changes from r5769:
|
||||
|
||||
1. Numerous bug fixes
|
||||
2. Double-click on decoded message now behaves properly
|
||||
3. Faster decoding (further optimization still to come)
|
||||
4. Decoded text is highlighted as in WSJT-X slow modes
|
||||
5. Optional auto-sequencing
|
||||
|
||||
Fair warning: auto-sequencing is basically functional, but scarcely
|
||||
tested. Please watch what it is doing, and tell us how you think it
|
||||
should be improved!
|
||||
|
||||
If you use WSJT-X also for other modes and other purposes, you may
|
||||
want to save several different sets of configuration settings. In
|
||||
that case it's convenient to use the "-r xxx" option and start the
|
||||
program from a command-prompt window. For example:
|
||||
|
||||
C:\Users\joe> cd \wsjt\wsjtx\bin
|
||||
C:\WSJT\wsjtx\bin> wsjtx -r xxx
|
||||
|
||||
... where "xxx" can be anything you like, for example "ISCAT",
|
||||
"FAST9", etc.
|
||||
|
||||
Proper configuration for the JT9 fast modes includes the following
|
||||
settings:
|
||||
|
||||
On the Settings | General tab:
|
||||
|
||||
- check "Enable VHF/UHF/Microwave features"
|
||||
|
||||
Main window settings:
|
||||
|
||||
- Mode JT9
|
||||
- Tx 700 Hz
|
||||
- Rx 700 Hz
|
||||
- Sync 0
|
||||
- Submode G ... or E, F, and H (H not legal in US on 10m)
|
||||
- Tick "Fast"
|
||||
- T/R 30 s (also 5, 10, 15 s)
|
||||
- FTol 500
|
||||
|
||||
Please keep in mind that this is an experimental version of WSJT-X.
|
||||
It still has some rough edges, and no doubt some bugs. Your feedback
|
||||
will be much appreciated, and will help to make the program better!

Possible FT8 Enhancements for Contesting
|
||||
----------------------------------------
|
||||
|
||||
In addition to all the standard FT8 messages, FT8 DXpedition Mode
|
||||
defines a new message type to convey messages like this example
|
||||
acknowledging completion of a QSO with K1ABC and initiating a QSO with
|
||||
W9XYZ:
|
||||
|
||||
K1ABC RR73; W9XYZ <KH1/KH7Z> -11
|
||||
|
||||
With 15s T/R sequencing and otherwise using standard FT8 messages,
|
||||
this feature allows QSO rates up to 120/hour with one Tx signal. The
|
||||
callsign enclosed in angle brackets is sent as a 10-bit hash code.
|
||||
|
||||
High QSO rates are also desirable for contest operating, but some
|
||||
details are quite different from the DXpedition case. Contesting is a
|
||||
many-to-many (as opposed to many-to-one) activity. We distinguish
|
||||
between "Run stations" and "S+P stations" rather than between "Fox"
|
||||
and "Hounds".
|
||||
|
||||
An optimal sequence of messages suitable for contesting looks
|
||||
something like the list in Table 1, where {exch} represents the
|
||||
required contest exchange. With 15 s transmissions and a steady
|
||||
stream of callers, messages like these can support QSO rates
|
||||
approaching 120/hour.
|
||||

||||

|

|

In some circumstances one or both station callsigns may safely be
|
||||
taken as known by context. High-rate contest transmissions in SSB,
|
||||
CW, and RTTY can therefore be considerably shortened with no resulting
|
||||
ambiguity for attentive operators. CQing stations need not include
|
||||
their own callsign in every transmission, while S+P stations may send
|
||||
only their own callsign at first, as in line 2 of Table 2, and then
|
||||
only the contest exchange, as in line 4.

||||

|
||||
|
||||
There would be no advantage to such message brevity with FT8. FT8
|
||||
transmissions are of fixed duration, by design; and the AP decoder can
|
||||
treat the home callsign and previously decoded callsigns as
|
||||
hypothetically given, thereby making the effective code rate lower and
|
||||
sensitivity up to 4 dB better.
|
||||
|
||||
Required exchange information for some relevant contests is
|
||||
illustrated in Table 3, along with a breakdown of bit requirements for
|
||||
each component of the exchange. Lower-case letter-number combinations
|
||||
such as r1, r3, s7,... in the table suggest the meanings and indicate
|
||||
the number of bits required to convey each part of the exchange.
|
||||
Further details are given below the Table. Parameter T1 is the total
|
||||
number of exchange bits, and T2=T1+56 is the number of bits for the
|
||||
full message, including two standard 28-bit callsigns.

How best to accommodate all these possibilities within the 72+3-bit
|
||||
FT8 message payload? Let i3 (aka "i3bit") denote message type, with
|
||||
available range 0-7. Type 0 is already used for standard JT-style
|
||||
structured messages and free text, and type 1 for DXpedition mode.
|
||||
Examples of suggested new message types 2 through 6 are summarized in
|
||||
the Table 4.

|
||||
|
||||
The first callsign in a message can also be "CQ" and a few other
|
||||
special tokens. Type 3 messages are the same as type 2 except for
|
||||
including "TU;", the completion-of-QSO indicator. Message fragments
|
||||
x16 and x25 represent generic contest exchanges. A "contest template"
|
||||
will define the specific source encoding/decoding needed for each
|
||||
event.
|
||||
|
||||
Suggested message types 4 and 5 use a 17-bit hash for the first
|
||||
callsign. I'm imagining that we'd start with a 32-bit crc and then
|
||||
use its remainder after dividing by the prime number 131063. Values
|
||||
less than 131063 will be the desired hash code, and the nine values
|
||||
131063-131071 can be assigned special meanings such as CQ, QRZ, etc.
|
||||
Type 4 messages identify the transmitting station as a Rover and can
|
||||
also accommodate 6-digit grid locators. Type 5 messages allow the
|
||||
transmitting station to send a full compound callsign with add-on
|
||||
prefixes up to 4 characters and suffixes up to 3. Compound callsigns
|
||||
are also permissible for the hashed callsigns in message types 4 and
|
||||
5.
|
||||
|
||||
Contest Operating
|
||||
-----------------
|
||||
|
||||
Operating in this proposed FT8 Contest Mode would be similar to that
|
||||
in current RTTY contests. CQing stations will be distributed over 20
|
||||
kHz or more on each band, perhaps at ~500 Hz separation. They will
|
||||
respond to callers on their own frequency +/- ~200 Hz. Thus, a CQing
|
||||
station and callers should occupy no more than 500 Hz total bandwidth.
|
||||
CQers might always transmit at Tx audio frequency 1750 Hz and
|
||||
configure their FT8 decoders to respond to signals between 1500 and
|
||||
2000 Hz. S+P stations will typically work their way up or down the
|
||||
band, perhaps in steps of 2 or 3 kHz, looking for unworked CQers. The
|
||||
FT8 Contest GUI will offer special features for CQ mode and S+P mode
|
||||
that make such conventions easy to follow.
|
||||
|
||||
Some Pertinent Questions
|
||||
------------------------
|
||||
|
||||
1. FT8 is a good mode, but does it make for a good contesting mode?
|
||||
|
||||
The model described above maxes out at 120 QSOs/hour. (One can
|
||||
imagine SO2R or even SO3R extensions, doubling or tripling that
|
||||
limit.) Should we consider T/R sequences of 10s, or even 5s, to get
|
||||
potentially higher rates? Should we consider giving up synchronized,
|
||||
fixed-length sequences entirely, and use operator-determined start
|
||||
times and transmission lengths? That's a significant departure from
|
||||
all existing WSJT-X modes.
|
||||
|
||||
2. How much automation should be permissible?
|
||||
|
||||
We're not aiming to make a contesting robot. We want something that
|
||||
rewards operator and station performance. The recently introduced FT8
|
||||
DXpedition Mode offers the "Fox" operator a list of decoded "Hounds"
|
||||
sorted by Call, Grid, S/N, Distance, or Random order. Hounds must
|
||||
initiate their calls to Fox, and Fox must manually select each Hound
|
||||
to be called. Otherwise, QSOs proceed with standard FT8
|
||||
"auto-sequencing". Is this model acceptable?
|
||||
|
||||
3. How much bandwidth? How much sensitivity?
|
||||
|
||||
RTTY signals use bandwidth ~220 Hz and require S/N around -5 dB or
|
||||
better, measured in a 2500 Hz bandwidth. FT8 uses signal bandwidth 50
|
||||
Hz and reaches threshold sensitivity between -20 and -24 dB, depending
|
||||
on how much a priori (AP) information is available. Shorter
|
||||
transmissions conveying the same messages would increase the
|
||||
bandwidth, S/N threshold, and potential QSO rate proportionally. Has
|
||||
FT8 already hit the "sweet spot" of such trade-offs?
|
||||
|
||||
4. Suitable power limits?
|
||||
|
||||
WSJT-X modes are designed as weak-signal modes. They have strong FEC
|
||||
and don't suffer from partial or corrupted copy. Sensitivity already
|
||||
beats RTTY by 15-19 dB, so arguably it makes sense for an FT8 contest
|
||||
or contest category to be limited to 100 W or even QRP power levels.
|
||||
|
||||
5. What software should provide the operator's GUI?
|
||||
|
||||
Things are described above as though WSJT-X, the software that
|
||||
introduced FT8, would be used for contest operating. WSJT-X can send
|
||||
QSO information to N1MM+ and other logging programs, so they could be
|
||||
used in combination with WSJT-X. Alternatively, we could set things
|
||||
up so that N1MM+ is the control program and FT8 encoding/decoding is
|
||||
provided by a plug-in "MMFT8" similar to MMTTY. Operators already
|
||||
into serious RTTY contesting would probably like the N1MM-in-control
|
||||
option. However, existing FT8 users might be more comfortable with
|
||||
WSJT-X in full control. Moreover, WSJT-X offers full support for
|
||||
Linux and MacOS, which N1MM+ does not.
|
||||
|
||||
########################################################################
|
||||
|
||||
More thinking, beyond the above...
|
||||
|
||||
FT8 currently uses LDPC(174,87), where 87=72+3+12. Suggest going to
|
||||
LDPC(174,91), with 91=72+5+14. This would give us 32 message types
|
||||
rather than 7, and stronger suppression of false decodes. SNR penalty
|
||||
would be 10log(91/87)=0.2 dB.
|
||||
|
||||
MSK144 currently uses LDPC(128,80), where 80=72+8. Suggest going to
|
||||
LDPC(128,87), with 87=72+5+10. SNR penalty is 0.4 dB.
