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 Status(1) message acquires the new fields Frequency Tolerance, T/R
Period, and Configuration Name. The Rx DF, Tx DF fields become
unsigned (this should be a benign change which is just for correctness
as -ve values have never been possible).
The Close(6) message becomes bi-directional allowing external
applications to gracefully close down WSJT-X instances.
A new message SwitchConfiguration(14) is provided that allows an
external application to switch the current configuration of a WSJT-X
instance.
Another new message Configure(15) is provided to allow external
applications to adjust some key parameters like the mode and submode.
See the NetworkMessages.hpp header commentary for full details. The
UDPExamples/MessageAggregator reference application has been updated
to be able to exercise all of the above changes.
Note that this commit enforces stricter checking on the
"Settings->Reporting->Allow UDP requests" option, which must be
checked before any state changing incoming messages to a WSJT-X
instance are processed.
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.
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.
When "Auto Grid" is checked in "Settings->General" UDP messages of
type "Location" will update a temporary DE grid square. The intent is
to allow an external application joining the WSJT-X UDP message
protocol to dynamically update the DE grid during mobile operation.
This change also tidies up some outstanding issues around logging the
operator call.
This change adds a new UDP message "Logged ADIF" that is emitted in
parallel with "QSO Logged" messages. The new message is valid ADIF
file format and contains the logged QSO fields. The intent is that
basic UDP server applications might already have ADIF log record
capture capabilities and could use this message to feed existing ADIF
parsing routines to log QSOs. All that should be needed is to identify
this message type and the single field is ADIF compatible ASCII.
Thanks to Brian, N9ADG, for the patches that lead to these
enhancements.

Measure check box added to FreqCal mode, check to record to fmt.all
with current calibration correction disabled, uncheck to see the
impact of the current calibration parameters.
The fmt.all file is now optionally renamed to fmt.bak when a
calibration solution is accepted. This allows users to preserve an
fmt.all file that they might have edited for best fit.
A calibration procedure might proceed thus:-
1) select FreqCal mode,
2) step through suggested calibration test frequencies deleting those
that have no usable signal,
3) enable "Menu->Tools->Execute frequency calibration cycle" and check
that suitable signals are present,
4) select a suitable FTol and T/R period,
5) check "Measure" and let the cycle complete a few times to gather
data,
6) uncheck "Measure" to complete the data capture, optionally tidy the
fmt.all file with your favourite editor,
7) push "Menu->Tools->Solve for calibration parameters" and accept if
you like what you see,
8) sit back and admire your accurately frequency calibrated station.

Make calibration solution application iterative so that calibrations
can be applied sequentially if desired.
Tidy up calibration solution messages boxes and make i18n friendly.

1. Checkbox "Double-click on call sets Tx and Rx freqs" has been removed
from the Settings -> General tab.
2. Checkbox "Lock Tx Freq" on main window is relabled "Hold Tx Freq".
3. Behavior now defaults to the "simplex" behavior in use up to code
revision r8123. In particular, double-clicking on decoded mesages
that do not contain your own call moves both Rx and Tx frequencies.
If the first callsign is your own call, only Rx freq moves.
4. If "Hold Tx Freq" is checked, double-clicking on decoded messages
moves the Rx frequency; Tx frequency is moved only if CTRL was held
down.
5. Clicking on the waterfall moves Rx and Tx frequencies as before:
Rx only on a simple click, Tx only on SHIFT-click, and both on
CTRL-click. This happens even if "Hold Tx Freq" is checked (which
is why this box is no longer labeled "Lock Tx Freq").

Note that reverting to v1.7 will invalidate any saved working
frequencies from v1.8 but proceeding to v1.8 again will present a
reset set of working frequencies i.e. any user defined entries in v1.8
will be lost of a v1.8 -> v1.7 -> v1.8 transition is made.
git-svn-id: svn+ssh://svn.code.sf.net/p/wsjt/wsjt/branches/wsjtx@8018 ab8295b8-cf94-4d9e-aec4-7959e3be5d79
Working frequencies can be for all regions or for individual IARU
regions. This allows each mode band tuple to have one or more working
frequencies which can include local ones only offered when the user
configures their IARU region.
Change working frequency default suggestions to better fit in
FT8. General rule is FT8 is at JT65 -2kHz except where that is not
possible e.g. where that would fall into a segment not allocated for
narrow band data modes. For tight bands like top band sqeeze existing
JT65 and JT allocations to allow space for FT8.
NOTE: this change changes the WSPR frequency on 80m to allow access to
JA stations that currently have no allocation where it was placed.
ALSO NOTE: the JT65 and JT9 frequencies for 80m move down 6 kHz, again
to accommodate region 3 users. Other appliactions not within our
control should be asked to move in step when 1.8.0 is released.

This builds on the static phase compensation in the MSK144 decoder and
the phase analysis and polynomial fitting capabilities also in teh
MSK144 decoder, by allowing captured data to be selected for phase
equalization from the WSJT-X UI.
Reads captured phase compensation curve estimate files containing
fitted polynomial coefficients and measured phase data from MSK144
receptions. Intent is to select a compensation curve that is from a
known transmitter like an SDR which have good phase linearity. Phase
plots and compensation polynomials may be viewed and compared with the
current compensation polynomial. A suitable polynomial can be applied
to be use in all further decoding of MSK144 signals.
Plots of the currently selected polynomial and its modified higher
order terms polynomial which is actually used in equalization (this
plot may be dropped - it is just for kicks at the moment). When a
captured phase analysis file is loaded plots of the measured phase and
the proposed best fit polynomial are shown.
Basic maintenance is also included allowing clearing and loading
captured plots and an option to revert to a flat no equalization
curve.
More to come on this as amplitude equalization is also possible, this
will probably be similar, maybe even plotted on the same graph with
dual axes for phase and amplitude. Amplitude correction from a
measured reference spectrum could be viewed and selected for
equalization for all modes. TBC...
This change also introduces the QCustomPlot 3rd party
widget. Currently this is statically linked from a qcp library built
by the WSJT-X CMake script. This will probably be migrated to a shared
object (DLL) build as a CMake external project, once some CMake script
re-factoring has been completed, which is more in line with the
QCustomPlot author's intentions. This will allow efficient reuse in
other tools shipped with WSJT-X.
