4cebdddfe5 Add multiple configurations navigation and management
Multiple configurations  are accessed and  maintained from a  new main
window menu bar  pop up menu "Configurations". The  prior settings are
the  "Default"  entry. New  configurations  may  be added  by  cloning
existing ones.  Maintenance  and navigation is via sub  menus for each
configuration.

2cfbb15b4f Rig control overhaul to implement generic Doppler shift tracking
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.

924e20efa8 Add a sample download dialog and upload sub-system
Samples are  downloaded from a  web server, currently the  SF download
server.   The samples  are  stored in  the  source controlled  samples
directory and the CMake script  there builds a suitable directory tree
for upload to the web  server under samples/web containing the samples
hierarchy and the  generated JSON contents database  file. The samples
CMake script also  defines an 'upload-samples' target  that uses rsync
to efficiently upload  the samples and the  accompanying contents JSON
database file.

Any directory structure under the samples directory may be created, to
add a new sample file simply add  the file to source control and amend
the list of sample files (SAMPLE_FILES) in samples/CMakeLists.txt.

d5bc774641 Get rid of jt9com and npar common blocks
Also  use correct  C binding  and have  compilers determine  sizes and
offsets.

The wsjtx.exe program now owns the  decoder shared data that is shared
with symspec.  It is now in  struct dec_data, still a  global variable
for now but hopefully a MainWindow member variable soon.

The struct  dec_data (in both C/C++  and Fortran) has a  sub structure
with the decoder  parameters which enables copying  and manipulating a
lot cleaner.

New  of  changed types  of  shared  data  must  still be  modified  in
commons.h and a  new file lib/jt9com.f90, they must stay  in sync as a
pointer to the structure is passed between C and Fortran.

3dd824ad6b Make the main window more portable and font change capable
The Rx meter  is now a better  Qt citizen and can be  resized. Added a
more obvious peak signal indicator. It  is now a custom widget derived
from QFrame and is now directly added via promotion in Designer.

Added a custom  widget to act as  a letter spin box, this  is used for
sub mode control.  Switched the frequency tolerance widget  to a combo
box with preset  values so that it is more  uniform across systems and
font sizes.

Added container widgets  for group control of various  UI widgets such
as  QSO controls,  DX call  controls and  WSPR controls.  Introduced a
stacked widget to allow the WSPR controls to be swapped in in place of
the "QSO" controls. The "QSO" controls  are are the Rx, Tx and related
controls along with  the main tab widget with the  message buttons and
fields. This means  that the WSPR version of the  main window (and EME
Echo mode) are now much cleaner.

Increased the  size of the  rig control  widget and styled  its colour
using a dynamic property so that it  can be defined in the Designer UI
definition. Reinstated it  as a push button to do  a rig control reset
and retry after an error.

Reset most UI widgets to default properties, particularly removing any
fixed sizes so that they can resize freely when fonts are changed. The
overall layout is now controlled almost exclusively by stretch factors
on some of the rows and columns of the various grid layout managers.

f200506571 Add mode dependent working frequencies
Working frequencies are mode dependent  and a reset to defaults button
has been added.

Also re-factored much of the model  and item delegate code to simplify
several  of the  model  implementations. Introduced  a single  routine
called from main to register the custom types with Qt.

3f75b4144a Send status information to UDP server
To  facilitate interaction  with other  applications WSJT-X  now sends
status  updates  to  a  predefined   UDP  server  or  multicast  group
address. The  status updates include the  information currently posted
to  the  decodes.txt and  wsjtx_status.txt  files.   An optional  back
communications  channel is  also implemented  allowing the  UDP server
application to control some basic actions in WSJT-X.

A reference implementaion of a typical UDP server written in C++ using
Qt is  provided to demonstrate  these facilities. This  application is
not intended  as a user  tool but  only as an  example of how  a third
party application may interact with WSJT-X.

The  UDP messages  Use QDataStream  based serialization.  Messages are
documented in  NetworkMessage.hpp along with some  helper classes that
simplify the building and decoding of messages.

Two  message  handling  classes   are  introduced,  MessageClient  and
MessageServer.  WSJT-X uses the MessageClient class to manage outgoing
and  incoming  UDP  messages   that  allow  communication  with  other
applications.   The MessageServer  class implements  the kind  of code
that a  potential cooperating  application might use.   Although these
classes  use  Qt serialization  facilities,  the  message formats  are
easily  read and  written  by  applications that  do  not  use the  Qt
framework.

MessageAggregator   is   a   demonstration   application   that   uses
MessageServer and  presents a GUI  that displays messages from  one or
more  WSJT-X instances  and  allows sending  back a  CQ  or QRZ  reply
invocation  by double  clicking  a decode.   This  application is  not
intended as  a user facing tool  but rather as a  demonstration of the
WSJT-X UDP messaging facility. It  also demonstrates being a multicast
UDP server by allowing multiple instances to run concurrently. This is
enabled by using an appropriate  multicast group address as the server
address.  Cooperating   applications  need  not   implement  multicast
techniques but  it is recomended  otherwise only a  single appliaction
can act as a broadcast message (from WSJT-X) recipient.
