where possible audio devices that disappear are not forgotten until
the user selects another device, this should allow temporarily missing
devices or forgetting to switch on devices before starting WSJT-X to
be handled more cleanly. If all else fails, visiting the Settings
dialog and clicking OK should get things going again. Note that we
still do not have a reliable way of detecting failed audio out
devices, in that case selecting another device and then returning to
the original should work.
Enumerating audio devices is expensive and on Linux may take many
seconds per device. To avoid lengthy blocking behaviour until it is
absolutely necessary, audio devices are not enumerated until one of
the "Settings->Audio" device drop-down lists is opened. Elsewhere when
devices must be discovered the enumeration stops as soon as the
configured device is discovered. A status bar message is posted when
audio devices are being enumerated as a reminder that the UI may block
while this is happening.
The message box warning about unaccounted-for input audio samples now
only triggers when >5 seconds of audio appears to be missing or over
provided. Hopefully this will make the warning less annoying for those
that are using audio sources with high and/or variable latencies. A
status bar message is still posted for any amount of audio input
samples unaccounted for >1/5 second, this message appearing a lot
should be considered as notification that there is a problem with the
audio sub-system, system load is too high, or time synchronization is
stepping the PC clock rather than adjusting the frequency to maintain
monotonic clock ticks.
Fixed buffer sizes are used. Rx use s 3456 x 1st downsample rate x 5
audio frames of buffer space. On Windows this means that each
chunk (periodSize()) delivered from the audio stream is our initial
DSP processing chunk size, thus matching audio buffer latency exactly
with WSJT-X's own front end latency. This should result in optimal
resilience to high system loads that might starve the soundcard ADC of
buffers to fill and case dropped audio frames.
For Tx a buffer sufficient for 1 s of audio is used at present, on
Windows the period size will be set to 1/40 of that which gives
reasonably low latency and plenty of resilience to high system loads
that might starve the soundcard DAC of audio frames to render. Note
that a 1 s buffer will make the "Pwr" slider slow to respond, we may
have to reduce the Tx audio buffer size if this is seen as a problem.
Adjusting these may help with audio drop-outs, particularly on slower
CPU systems or heavily loaded systems. Smaller buffer sizes leave less
margin for process interruptions, larger sizes waste resources that
could impact other processes.
the decoders. Also, an experimental change to the FT4 decoder to base
AP decoding passes on 4-symbol block detection instead of single symbol
detection. This provides about 1 dB improvement on the AWGN channel.
Sensitivity changes on other channels are TBD.
This is a check box option in "Settings->Colors" rather than new
highlighting types so un-worked field highlighting and un-worked grid
square highlighting are mutually exclusive. The check box state can be
changed at any time, no log rescanning is necessary, and subsequent
decoded message highlighting will be according to the check box state.

The second UDP server and port are noted as deprecated since that
channel is no longer used for its original purpose, namely N1MM
Logger+ consumption of ADIF logged QSO records. This has been marked
as deprecated rather than removing since other applications have
unilaterally chosen to use this feed rather than the documented WSJT-X
UDP message protocol which contains the same information and
more. Expect this UDP channel to be removed in some future WSJT-X
release.
When RR73 is received we log the QSO, turn "Call 1st" OFF, and call CQ again.
Also, allow Alt+C and F6 (the latter only if altenrate F1-F6 bindings
are active) to toggle "Call 1st" ON/OFF.
Add "Settings->Colors->Decode Highlighting" context menu buttons to
unset b/g and f/g colours. Add colour value as #rrggbb or unset in
text to list items. Improved colour assignment to decodes giving
better and more intuitive behaviour.
This change incorporates a reorganization of the GUI code with
widgets, validators, models, and item delegates being moved to
sub-directories.
Relax the requirements of the ForeignKeyDelegate and related
CandidateKeyFilter classes to allow them to work with constant model
pointers for both referenced and referencing models.
Make the group box checkable and the radio buttons mutually exclusive.
Prevent switch from any other mode to MSK144 and put up an error box if the contest radio button setting is not allowed for MSK144.
If currently in MSK144 mode and an invalid contest type is selected, put up an error box and change mode to FT8 where any contest type is allowed.
Settings option to highlight not worked before entities/grids/calls by
mode. Fix issues with highlighting decodes and generally refactor the
internal workings of ADIF and QSO recording for worked before
detection.
Drag'n'drop highligting items in "Settings->Colors" to set priorities,
higher up is higher priority. The default priorities and colours have
been changed to give a reasonable starting configuration.
Includes a new settings facility with the highlighting being contrled
by a new model class and a modified QListView to display the data for
editing. Edits include enable and disable check boxes, a contextual
pop-up menu to adjust backkground and foreground colours.
Still to be implemented are priorities for highlighting
categories. This will be adjustable by drag and drop in the Colors
settings panel, it is already implemented by the priority order has no
effect on highlighting of decodes yet.
The LotW users data file fetch and time since user's last upload is
now controled from the settings dialog.
This change also drops support for Qt versions before 5.5 so that many
workarounds for earlier versions can be removed.
Debug trace is slightly modified to make better use of the Qt built in
facilities to format and synchronize cross thread messaging.
