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, 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.
|
|
||||||
|
|
||||||

---------------
|
|
||||||
|
|
||||||
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!
