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.

Because Commander queues up CAT commands the timing of Tx audio was
not being correctly synchronized to the rig PTT. This change polls the
rig PTT state after changing PTT and waits for it to go to the
expected state. As it happens, just doing a query does most of the
synchronization as the query gets queued behind the PTT directive
within Commander, with the reply being delayed until the query
completes. This change goes further and checks the PTT state changes
within one second.
Note that users using Commander will should not suffer from ALC
overshoot issues on rigs that suffer such a problem since Tx audio now
only commences after the rig has switched to transmit. Users with
hardware sequencers may need to adjust their "Settings->Advanced->Tx
Delay" parameter, this change does not introduce any new timing hazard
but there may be a slight lengthening of the delay to Tx audio if the
rig reports PTT via CAT as the audio delay may now be timed from the
actual PTT on the rig rather than the assertion of RTS/DTR.
Still outstanding is the slow processing of Commander CAT requests
which can cause considerable delays before Tx audio can start.
git-svn-id: svn+ssh://svn.code.sf.net/p/wsjt/wsjt/branches/wsjtx@7764 ab8295b8-cf94-4d9e-aec4-7959e3be5d79
When using split operating and/or rig mode setting there is a delay
before PTT is asserted while the CAT commands are processed. There
will even be a small delay if CAT is only used for PTT. This change
waits for these commands to be completed before starting the user Tx
delay specified in the settings.
There is a notable exception to this in that DX Lab Suite Commander
does not give us a way of knowing when CAT commands have actually been
completed. This combined with the way that Commander spaces CAT
commands, rather than being paced by the rig's CAT responses, means
that delays of more than 1 second are likely. As most rigs suffer some
sort of ALC overshoot when PTT is asserted with audio already present,
it is strongly recommended not to use the DX Lab Suite Commander as a
rig control proxy if your rig may suffer ALC overshoot and you use an
external PA. Please note that using a typical RF power meter to detect
ALC overshoots is unwise as they are rarely fast enough. It is
probably wise to assume that all rigs suffer ALC overshoot since it is
very difficult to design an ALC loop that avoids it.
This change also increases the range of the "Settings->Advanced->Tx
Delay" spin box to 0s up to 2s.

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.

1. Clean up mskrtd to remove unused variables.
2. Re-instate Rx frequency spinbox in MSK144 mode to allow decoding of off-frequency signals with small FTol. Make changes needed to pass Rx Freq in to fortran routines.

The watchdog configuration is now a spin box of minutes with a special
first value of disabled. WSJT-X counts down minutes on the minute, if
the countdown reaches zero any attempt to transmit is aborted. The
countdown is reset by any mouse press or key press event inside the
main window or if the Tx message changes (auto sequencing).
The status bar now shows the Tx watchdog countdown if it is
active. This information is shown to the right of the progress bar
text.
The warning message boxes triggered within the GUI update routine now
no longer block the GUI updates.

The concept of a nominal receive and transmit frequency has been
introduced. This is used as a base frequency for Doppler correction,
frequency setting and reporting. The start up frequency is now zero
which is updated by the first rig control status report. This needs
more work to accommodate calling frequency plus working frequency
operation as is used for random MS operation etc..
The main window frequency display now shows the transmit dial
frequency while transmitting.
The mode changing logic sequence has been changed such that the rig is
correctly put into and taken out of split mode as required by the
target mode. This also avoids the "other" VFO having its frequency
changed when entering a mode that does not use split operating like
WSPR.
The main window band combo box edit may now be used to input an kHz
offset from the current MHz dial frequency. This is intended for
setting a sked or working frequency on the VHF and up bands. For
example the working frequency for 23cms might be set to 1296MHz and a
working frequency of 1296.3MHz would be selected by selecting the
23cms band with the combo box drop down list and then entering 300k
into the band combo box edit widget.
When using JT4 modes a CTRL+Click on the waterfall adjusts the nominal
frequency such that the frequency clicked on becomes the Tx and Rx
frequency using the fixed 1000Hz DF that JT4 modes use. This will
probably be extended to all QSO modes when used in VHF & up mode. This
assumes that 1000Hz is an optimal DF for both Tx and Rx and therefore
one can "net" to an off frequency, but visible on the waterfall,
caller with one click.
Improvements to OmniRig rig control including use of the serial port
control lines RTS or DTR, on the CAT serial port used by OmniRig, for
PTT control.
Incrementing transaction sequence numbers added to messages to and from
the rig control thread. This enables round trip status to be tracked
and associated with a request. For example a command that might cause
several asynchronous status updates can now be tracked in the
originating thread such that it is clear which updates are caused by
executing the request. This in turn allows updates to be held until
the request is complete i.e. the state is consistent with the results
of the request.
Messages to the rig control thread are now posted as a new state
(Transceiver::TransceiverState) object. The rig control thread tracks
requests and actions any differences between the prior requests and
the new state.
The rig control thread is now stored on the heap so that it can be
closed down and released as needed. Along with this the rig control
close down semantics are better defined avoiding some potential
deadlock situations.
If the rig is placed into split mode it will be reverted to simplex
mode when the rig connection is closed.
When using direct rig control via Hamlib, rigs that have A/B VFO
arrangements and no method to query the current VFO like many Icoms
and the Yaesu FT-817/857/897(D) series now have smarted frequency
updating requiring no VFO changes when changing the frequency. This
is particularly important when doing Tx Doppler correction to avoid
glitches.
The implementation of emulated split operating mode ("Fake It") is
simplified and improved.
A dummy Hamlib transceiver for PTT control on a separate port is no
long instantiated if CAT or VOX PTT control is selected.
The resolution and any rounding of the rig CAT frequency set and get
commands is determined automatically upon opening the rig connection.
This is needed to determine the rate of frequency updates for Doppler
tracking. It also allows the rig to be more accurately controlled.
Frequency calibration is calculated separately for the receive and
transmit frequencies.
Whether the rig modulation mode should be controlled is now a
constructor argument rather than being passed with individual rig
control requests.
Doppler shift correction is considerably enhanced with simpler
controls and much better rig control. A new mode of tracking called
"receive only" is introduced for those with rigs that cannot be QSY:ed
via CAT when transmitting. Such rigs have a Doppler correction
calculated for the middle of the next transmit period just before
transmission starts. While using Doppler tracking it is now possible
to adjust the sked frequency either using the new kHz offset feature
of the main window band combo box or by directly tuning the rig VFO
knob while holding down the CTRL key.
The astronomical data window that includes Doppler tracking control is
now opened and closed using a checkable menu item to avoid it being
accidentally closed.
Debug configuration rig control diagnostic messages now have a
facility argument for clearer and more standardized trace messages.
