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.
- Color highlighting scheme window fixed in dark mode.
- Reports sent by QSO partners to other stations no longer logged in
error.
- UDP Status(1) message now includes the current Tx message.
- Example diagnostic logging configuration files included.
- Use system localization for date fields in Log QSO dialog.
- Improvements to audio input and output buffer sizes.
- wsprd: Fails gracefully if data directory does not exist.
- wsjtx_app_version: new utility to print application version string.
- Regression causing incorrect working frequency selection when
changing modes repaired.
- Regression with QSO initiation with "Best S&P" repaired.
- Updated installation instructions for macOS covering M1 hardware.
- Improved compatibility is Debian 9 required distribution packages.
- Repair regression with missing time-stamps in the ALL.TXT journal.
- Allow hamlib_settings.json to work with PTT only configurations so
that optional PTT sharing on RTS or DTR can be enabled.
- Several improvements to main window sizing and layout.
- Repair regression with OpenSSL libraries being required when LoTW
highlighting is not enabled.
- Repair a defect that caused 2 by 1 callsigns to be incorrectly
parsed as non-standard.
- Several updates to international UI translations.
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.
