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.
