4a32b0bef6 Add facility to disallow CAT commands while transmitting.
Some rigs either do not honour some CAT commands while transmitting or
interpret them  incorrectly. To  deal with this  a settings  option to
allow TX  frequency changes while  transmitting has been added  with a
default value of off.

Any UI actions that directly or indirectly change the TX frequency are
guarded according to this new option. As well as this band changes and
use of  the +2kHz check box  are disabled and guarded  respectively in
transmit mode.

Mode changes via the menu are now disabled while transmitting.

When TX frequency changes are allowed; frequency changes are correctly
implemented while in tune mode.

Double clicking  decodes while  transmitting now  correctly regenerate
and change the message sent on the fly.

6689558be8 Make CW envelope shapng the default.
Now I have verified that the CW envelope shaping considerably reduces
the bandwidth of teh CW id. I have made the it default. It can still
be turned off via a CMake option if desired.

No longer any need to have a mute mechanism since the TX shutdown
mechanism is sufficient.

a24a05fc5a Clean up Modulator code to ensure that partial blocks written are sent
with the correct length. This was causng some CW identifications to be
delayed and truncated occasionally.

f076c37c19 Made the soft keying CW wave shaper a CMake option (off by
default).

Reorganized Modulator interface so that it can control the stream
it writes to.

Make sure only QAudioOutput::stop is called at the end of sending
rather than QAudioOutput::reset which discards pending samples.

Added a quick close option to the Modulator::stop slot to discard
pending buffers if required.

Fix issue in CW synthesizer that was causing CW to be inverted
occasionally.

Made global arrays of symbols volatile because compiler waa
optimizing away reads in sound thread. These global variables
must go eventually as they are a multi-threading hazard.

Simplified TX sequencing to remove some duplicate signals.

Increased range of TX attenuator from 10dB to 30dB. This is mainly for
non-Windows platforms where the attenuator isn't linearized correctly.

581691befb Rearranged sequencing of audio streams and devices.
The code  was starting streams linked  to closed devices which  may be
causing issues on  the Mac version.  I have refactored  to ensure that
devices are always opened before related audio streams are started.

Made .h C++ headers emacs friendly.

Removed some code in the MainWindow  contructor that read the log file
but failed to check if the file exists and didn't do anything with the
data anyway.

9247e10115 Added support for use of "Standard" locations for writable files.
This allows  writable files  to be  located in  the "correct"
         location for  each platform rather  than in the  directory of
         the  executable  which, in  general,  is  not recommended  or
         allowed in some cases.

         A preprocessor macro  WSJT_STANDARD_FILE_LOCATIONS is used to
         switch be tween old and new functionality, currently it is on
         by default.  It  can be turned off by defining  it to a false
         value (0)  or more simply  with cmake-gui setting  the option
         with  the same  name.  JTAlert  can  only work  with the  old
         non-standard file  locations until  Laurie VK3AMA  chooses to
         support the new file locations.

         Even  if the  above is  not  enabled; the  QSettings file  is
         written to a  user specific location so it will  be shared by
         all instances  of the  program (i.e.  across  upgrades).  See
         below for multiple concurrent instance support changes.

Added a command line parser module for Fortran.

         Added 'lib/options.f90'  to facilitate more  complex argument
         passing to jt9 to cover explicit file locations.

Changed the way multiple concurrent instances are handled.

         This is  to allow the program  to be run multiple  times from
         the same installation directory.

         A new wsjtx command line  optional argument is available "-r"
         or  "--rig"   which  enables  multiple   concurrent  instance
         support.  The  parameter of the  new option is a  unique name
         signifying  a rig  or equivalent.   The name  is used  as the
         shared memory segment key and  in window titles.  The name is
         also used to  access unique settings files  and writable data
         files like ALL.TXT  and log files.  No attempt  has been made
         to share these files between concurrent instances.

         If  "-r" or  "--rig" is  used  without a  parameter it  still
         enables  multiple   concurrent  instance  support   for  that
         instance.  All instances must use  a unique parameter, one of
         which may be empty.

         The        rig       name        is       appended        the
         QCoreApplication::applicationName() for convenient usage like
         window titles.

Set non Qt locale to "C".

         This ensures that C library functions give consistent results
         whatever the  system locale is set  to.  QApplication follows
         the system locale as before.  Thus using QApplication and its
         descendants  like widgets  and QString  for all  user visible
         formating will give correct l10n and using C/C++ library will
         give consistent formatting across locales.

Added top level C++ exception handling to main.cpp.

         Because  the   new  transceiver  framework   uses  exceptions
         internally, the main function now handles any exceptions that
         aren't caught.

Retired devsetup, replaced with Configuration.

         Configuration  is  a  class  that encapsulates  most  of  the
         configuration  behavior.   Because  rig configuration  is  so
         closely coupled with rig operation, Configuration serves as a
         proxy  for   access  to  the  rig   control  functions.   See
         Configuration.hpp  for  more  details  of  the  Configuration
         interface.

Menu changes.

         Various checkable  menu actions moved  from main menu  to the
         Configuration  dialog.   The  whole settings  menu  has  been
         retired with  the single  "Settings..."  action moved  to the
         file  menu  for  consistency  on  Mac  where  it  appears  as
         "Preferences" in line with Mac guidelines.

New data models for data used by the application.

         ADIF amateur band parameters,  free text message macros, spot
         working   frequencies  and,   station  information   (station
         descriptions and transverter offsets per band) each implement
         the  QAbstractItemModel interface  allowing them  to be  used
         directly with  Qt view widgets  (Bands.hpp, FrequencyList.hpp
         and, StationList.hpp).  Configuration  manages maintenance of
         an instance of  all but the former of the  above models.  The
         ADIF band  model is  owned by  Configuration but  requires no
         user maintenance as it is immutable.

Band combo box gets more functionality.

         This  widget is  now an  editable QComboBox  with some  extra
         input capabilities.

         The popup list is still the list of spot working frequencies,
         now  showing the  actual  frequency decorated  with the  band
         name.  This  allows multiple  spot frequencies  on a  band if
         required.

         The  line edit  allows direct  frequency entry  in mega-Hertz
         with  a completer  built  in to  suggest  the available  spot
         working frequencies.   It also  allows band name  entry where
         the  first  available  spot working  frequency  is  selected.
         Recognized band names are those  that are defined by the ADIF
         specification and  can be found  in in the  implementation of
         the ADIF bands model (Bands.cpp).

         If an out of band frequency  is chosen, the line edit shows a
         warning red  background and the  text "OOB".  Out of  band is
         only defined  by the  ADIF band limits  which in  general are
         wider than any entities regulations.

Qt 5.2 now supports default audio i/p and o/p devices.

         These devices are placeholders  for whatever the user defines
         as the  default device.   Because of  this they  need special
         treatment as  the actual device  used is chosen at  open time
         behind the scenes.

Close-down behavior is simplified.

         The close-down  semantics were broken such  that some objects
         were not being shut down cleanly, this required amendments to
         facilitate correct close down of threads.

User font selection added to Configuration UI.

         Buttons to set the application font and the font for the band
         and  Rx frequency  activity widgets  have been  added to  the
         Configuration UI to replace the file based font size control.

Free text macros now selected directly.

         The free text line edit  widgets are now editable combo boxes
         that have  the current free  text macro definitions  as their
         popup  list.   The old  context  menu  to  do this  has  been
         retired.

Astronomical data window dynamically formatted and has font a chooser.

         This window is now autonomous,  has its own font chooser and,
         dynamically resizes to cover the contents.

Double click to Tx enabled now has its own widget in the status bar.

QDir used for portable path and file name handling throughout.

The  "Monitor", "Decode",  "Enable  Tx" and,  "Tune"  buttons are  now
checkable.

         Being checkable allows these  buttons control their own state
         and rendering.

Calls to PSK Reporter interface simplified.

         In   mainwindow.cpp  the   calls   to   this  interface   are
         rationalized to just 3 locations.

Manipulation of ALL.TXT simplified.

         Moved, where possible, to common functions.

Elevated frequency types to be Qt types.

         Frequency  and FrequencyDelta  defined as  Qt types  in their
         meta-type system  (Radio.hpp).  They  are integral  types for
         maximum accuracy.

Re-factored rig control calls in mainwindow.cpp.

         The new  Configuration proxy  access to rig  control required
         many changes  (mostly simplifications) to the  MainWindow rig
         control code.  Some  common code has been  gathered in member
         functions   like   qsy(),   monitor(),   band_changed()   and
         auto_tx_mode().

Rig control enhancements.

         The  rig control  for  clients interface  is  declared as  an
         abstract    interface   (See    Transceiver.hpp).    Concrete
         implementations of this interface are provided for the Hamlib
         rig  control library,  DX Lab  Suite Commander  via a  TCP/IP
         command channel, Ham  Radio Deluxe also via  a TCP/IP command
         channel and, OmniRig via its Windows COM server interface.

         Concrete Transceiver implementations are expected to be moved
         to a separate thread after construction since many operations
         are blocking  and not suitable  for running in a  GUI thread.
         To facilitate this all  instantiation of concrete Transceiver
         instances are handled by  Configuration using a factory class
         (TransceiverFactory)   for   configuration  parameter   based
         instantiation.

         Various   common  functionality   shared  by   different  rig
         interface implementations  are factored out into  helper base
         classes that  implement or delegate parts  of the Transceiver
         interface.  They  are TransceiverBase  which caches  state to
         minimize expensive rig commands, it also maps the Transceiver
         interface  into a  more  convenient  form for  implementation
         (template methods).  PollingTransceiver that provides a state
         polling   mechanism  that   only   reports  actual   changes.
         EmulateSplitTransceiver  that  provides  split  operation  by
         QSYing on PTT state changes.

         EmulateSplitTransceiver can  be used with  any implementation
         as  it follows  the GoF  Decorator pattern  and can  wrap any
         Transceiver implementation.

         OmniRigTransceiver is  derived directly  from TransceiverBase
         since  it doesn't  require  polling due  to its  asynchronous
         nature.  OmniRigTransceiver is only built on Windows as it is
         a COM server client.  To build  it you must first install the
         OmniRig     client     on     the     development     machine
         (http://www.dxatlas.com/omnirig/).

         DXLabSuiteCommanderTransceiver          derives          from
         PollingTransceiver since  it is a  synchronous communications
         channel.   No  third  party  library  is  required  for  this
         interface.

         HRDTransceiver also derives from PollingTransceiver.  The HRD
         interface  library has  been  reverse  engineered to  provide
         functionality with  all available versions of  HRD.  No third
         party libraries are required.

         HamlibTransceiver  likewise  derives from  PollingTransceiver
         since  the Hamlib  asynchronous interface  is non-functional.
         Although this  class will interface with  the release version
         of Hamlib (1.2.15.3);  for correct operation on  most rigs it
         needs to  run with the  latest master branch code  of Hamlib.
         During development many changes to Hamlib have been submitted
         and accepted,  hence this requirement.  Hamlib  source can be
         obtained from git://git.code.sf.net/p/hamlib/code  and at the
         time of writing he master branch was at SHA 6e4432.

         The Hamlib interface directly calls the "C" interface and the
         modified rigclass.{h,cpp} files have been retired.

         There is a rig type selection of "None" which may be used for
         non-CAT  rigs, this  is actually  a connection  to the  dummy
         Hamlib device.

         PollingTransvceiver   derives    from   TransceiverBase   and
         TransceiverBase derives from the Transceiver interface.

         Each interface implementation offers  some possibility of PTT
         control via  a different serial  port than the CAT  port.  We
         also support PTT  control directly via a  second serial port.
         This is done  by delegating to a dummy  Hamlib instance which
         is   only   used   for   PTT  control.    This   means   that
         DXLabSuiteCommanderTransceiver,       HRDTransceiver      and
         OmniRigTransceiver  always  wrap  a  dummy  HamlibTransceiver
         instance.  The  factory class TransceiverFactory  manages all
         these constructional complexities.

         Serial port  selection combo  boxes are  now editable  with a
         manually  entered value  being  saved to  the settings  file.
         This allows  a non-standard  port device  to be  used without
         having to edit the settings file manually.

         For TCP/IP  network CAT  interfaces; the network  address and
         port  may  be specified  allowing  the  target device  to  be
         located on a different machine  from the one running wsjtx if
         required.  The  default used when  the address field  is left
         blank is the correct one for normal usage on the local host.

         Selecting a polling  interval of zero is  no longer possible,
         this  is because  the rig  control capability  can no  longer
         support one way connection.  This  is in line with most other
         CAT control software.

         In the Configuration dialog there are options to select split
         mode  control  by  the  software  and  mode  control  by  the
         software.  For  the former  "None", "Rig"  and "Fake  it" are
         available,  for  the latter  "None",  "USB"  and, "Data"  are
         available.  Because  tone generation is implicitly  linked to
         split mode  operation; it is  no longer possible to  have the
         software in split  mode and the rig not or  vice versa.  This
         may mean some rigs cannot be used in split mode and therefore
         not in dual JT65+JT9 until  issues with CAT control with that
         rig are  resolved.  Single  mode with VOX  keying and  no CAT
         control are still possible so even the most basic transceiver
         setup is supported as before.

         Configuration now  supports a  frequency offset  suitable for
         transverter   operation.     The   station    details   model
         (StationList.hpp) includes  a column  to store an  offset for
         each band if required.

CMake build script improvements.

         The CMakeLists.txt from the  'lib' directory has been retired
         with its  contents merged into the  top level CMakeLists.txt.
         Install  target support  has been  greatly improved  with the
         Release build  configuration now building a  fully standalone
         installation  on Mac  and Windows.   The Debug  configuration
         still   builds   an   installation   that   has   environment
         dependencies for  external libraries, which is  desirable for
         testing and debugging.

         Package target  support is largely complete  for Mac, Windows
         and, Linux, it should be possible to build release installers
         directly from CMake/CPack.

         Cmake FindXXXX.cmake  modules have been added  to improve the
         location of fftw-3 and Hamlib packages.

         Version numbers are now stored in Versions.cmake and work in
         concert with automatic svn revision lookup during build.  The
         version string becomes 'rlocal'± if there are any uncommitted
         changes in the build source tree.

Moved resource like files to Qt resources.

      	 Because location of resource files  (when they cannot go into
      	 the  installation directory  because of  packaging rules)  is
      	 hard to standardize.  I have used the Qt  resource system for
      	 all ancillary data files. Some  like kvasd.dat are dumped out
      	 to the temp (working directory)  because they are accessed by
      	 an external program, others like the audio samples are copied
      	 out so  they appear in  the data directory under  the default
      	 save directory.

4f4c535c4e Added audio channel support.
Audio input can be mono, left of stereo pair or, right of stereo
pair. Audio output can be mono, left of stereo pair, right of stereo
pair or, both of stereo pair (the same output goes to both channels in
both mode). Settings are remembered between sessions.

Stream channel suport is implemented mainly in the new AudioDevice
class which is now the base class of Modulator and Detector.

Audio channels are selected on the configuration screen. Only
supported channel configurations per device can be selected.

Audio output volume (actually attenuation) is now possible from the
GUI. I have added a slider control to the main window; I don't
necessarily propose this as a final release location for the widget as
I understand that changes to the main screen are sensitive. This
location is just a starting suggestion for a trial. The volume
(attenuation) setting is remembered between sessions and is not device
dependent. This addresses all issues of volume setting on *nix
versions since there is no need to use pavucontrol to set audio
levels. The volume (attenuation) action is logarithmic.

Shaped CW keying has been implemented in Modulator although it is
currently disabled as I am not 100% happy wth the implementation. If
you want to try it define the C++ preprocessor macro WSJT_SOFT_KEYING
in your build.

The Modulator instance has been moved to the same thread as the
SoundOutput instance as it should have been since the output callback
already operates in that thread. Cross thread slots are now correctly
called in a thread safe way as a result.

A number of files where in the SVN repository with DOS line endings
which I have removed. SVN users on Windows need set the config for
native line endings so that DOS line endings are automatically
stripped on checkin.

The DevSetup class now holds it's UI o the heap to reduce imapact on
build dependencies.

The application settings are now passed to objects from the main.cpp
file. Management of settings are moved to the responsible classes (top
level windows). This has involved a few settings moving groups so
users will see some settings reverting to default values on the first
run of an update.

Persistance of top level windows geometry and position is now handled
in the recommened manner (constructor for load, closeEvent for store
in modal windows and, hideEvent for store in modeless dialogs).

The MainWindow class now holds its children as members rather than
global variables.

The LogQSO class now hides its implementation and takes responsibility
for its own settings and widows rendering parameters. A new settings
file group is implemented to persist the LogQSO class settings.

The WideGraph class now hides its implementation and manages its own
settings and window rendering parameters.

a114b8c9ea 1. Capitalize names of palettes appropriately.
2. Remove (or comment out) most qDebug() statements.
3. Swap positions of labels 2 and 3 on status bar.
4. In "Split Tx" mode, transmit audio always between 1500 and 2000 Hz.
5. Rearrange positions of WideGraph controls.

ef586e4b58 Qt 5 Audio replaces PortAudio.
Currently only Qt5 or above is known to work with this code. It may be
possible to backport it to Qt4 if required.

Audio output goes back to a separate thread to try and minimize
stutters in streaming on Windows particularly.

A crash on Linux due to mishandling of stereo audio output has been
fixed and both left and right channels are now correctly synthesised
with identical contents.

Rigs are enumerated directly from hamlib API rather than running a sub
process reading output of rigctl -l. This was initially done to get
rid of some GUI thread blocking in the configuration dialog, but is
generally a better way of doing it anyway.

Some refactoring in MainWindow to accomodate the audio streaming,
modulation and detecting classes.

Exit handling for application refactored to use signals rather than
brute force event loop exit. This was required to get correct thread
shutdown semantics.

The GUI update timer is now stopped during application shutdown which
is necessary to stop crashes when shutting down gracefully with
signals and window close() calls.

There is an outstanding issue with Linux audio streams; the QAudio
Input/Output classes create a new stream name each time a stream is
started. This doesn't play well with PulseAudio utilities such as
pavucontrol to set stream volume as settings are lost every tx
period. I have tried to keep a single stream for all output but there
are problems restarting it that haven't been resolved yet.

The QtCreator project file has been rearranged a little because it
passes all the object files to the linker rather than using an archive
library. Since the GNU linker is single pass; the object files need to
be in a logical order with definitions appearing afer references to
them. This was required to avoid a linking error.

The lib/Makefile.linux has been enhanced to use the fortran compiler
to locate the correct version of the Fortran library to use. This is
necessary on the latest Linux distros because the unversioned symlink
to compiler support libraries is no longer provided. This only an
issue with mixed programming language links where the linker driver
for one language has to link support libraraies for another language.
