Changes for WS Tools
====================
LinWSJT 0.1 Alpha
First publically released version.
LinWSJT 0.1a Alpha
Fixed a major bug in the JT44 receive timing that caused almost guaranteed
failures.
Removed need for the Audio File library, the WAV handling is done withing
the CSoundFile class itself.
LinWSJT 0.2
Added graphical display of the received spectrum.
Added tabbing to keep WAV file decoding separate from real time decoding.
Averaging of the received data.
Validation of the typed text.
LinWSJT 0.3
Big performance improvement.
Internal restructuring based on (1), its a little simpler now.
New messages appear at the top of the list.
New option to decode the text of a message that has been rejected as being
too weak to be meaningful.
Fixed the counts of the messages in the average window.
Hopefully fixed the bug in the configuration code.
LinWSJT 0.3.1
Removed some error messages when ending the program.
If message text changes, it causes the transmitted message to be updated if
it is the currently selected message.
Fixed text expansion.
Added tab traversal to the main window.
Added messages regarding the audio level.
Lin WSJT 0.3.2
Changes build to use the C++ compiler reported by wx-config instead of a
hard coded name.
Changed calls to wxASSERT()
Updated the levels shown for Sync and dB using information from Joe Taylor.
Unfortunately because of the different way the program works, it is not
possible to exactly match the two programs.
Hopefully made the audio level on the graph look a little more reasonable.
LinWSJT 0.4
Fixed a bug in the recovered text logging function.
Implemented weighted averages which attempt to remove noise from the decoded
text, it appears to improve the data recovery.
Changed the program structure to make FSK441 implementation a little easier,
no user visible changes.
Added normalisation of correlation values and also signal strength
calculation which is now close to what WSJT reports.
Changed correlation co-efficients to stop the program being a little too
generous in its decoding.
First FSK441 version included.
LinWSJT 0.4.1
Added pup-up error boxes.
Lots of internal changes that aren't visible to the user.
Fixed a bug in the sound card code, it wouldn't transmit. Sorry folks.
LinWSJT 0.4.2
Fixed a bug in the FSK441 transmit section, you would get "Soundcard busy"
messages after transmitting once.
LinWSJT 0.4.3
Converted to use wxGTK 2.4 so LinWSJT is now Unicode compliant. This may
break compatibility with earlier versions of wxGTK.
Added a control on the JT44 screen to adjust the minimum level of the sync
quality to display the received message.
Added a control on the FSK441 screen to adjust the minimum level of the
acceptable burst length and strength.
New FSK441 decoding routines that are better than the ones used in the
previous release.
Added a clock to both JT44 and FSK441.
LinWSJT 0.4.4
Fixed a Unicode problem in Clock.cpp
Returned the top level Makefile to using the generic wx-config.
Added more to INSTALL from README to make a few things clearer.
Fixed wxGTK to use GTK2 correctly, the patch is included in the LinWSJT
distribution but is not recommended for most people, stay with GTK1 is my
advice.
Minor bug in FSK441 receiving when receiving a continuous strong signal
would cause an error.
LinWSJT 0.4.4a
Added GPL copyright to the top of the source files. No code changes.
LinWSJT 0.4.5
Removed the parallel port PTT driver, nobody uses it and it wasn't tested
anyway.
Reduced output audio level by 3dB to remove possibility of clipping or other
distortion in the sound card.
Decoding of FSK441 single tone messages is an option from the Preferences
dialog box. LinWSJT doesn't transmit single tone messages. An idea from Ivan
HA5TS.
Cannot have single tone and multi tone characters in a single FSK441 message.
An idea from Andy K0SM.
Removed the saving of "TX Enable" between runs of the programs, default is
off. An idea from Andy K0SM.
Fixed a bug in the FSK441 strength setting. Spotted by Andy K0SM.
LinWSJT 0.4.6
Fixed a bug in FSK441 that caused it to crash on occasion. Spotted by Morten
LC1OCT.
Fixed 'l' and 'm' being swapped in FSK441. Spotted by Morten LC1OCT.
Changed default values to be G4KLX/IO93FB instead of HB9DRD/JN47HI.
Changed tone generation from an IFFT to a Numerically Controlled Oscillator
(like WSJT uses), this may reduce the transmitted bandwidth as the different
tones are now continuous in phase.
Compiled with the -march=pentium compiler line which should yield some speed
improvements.
Added Moon tracking to JT44.
Made JT44 a little less sensitive to synchronisation data, so false triggers
should be less likely.
Added two new programs in the tools directory. They are "Noise" and
"ToneGenerator" and are documented in the README in that directory.
Removed the LinWSJT.doc file. It can still be downloaded from my web pages
or found on dead wood in DUBUS 4/2002.
The IDs in both FSK441 and JT44 were in local time, they are now in UTC to
match the clock.
JT44 and FSK441 are more tolerant of low audio levels.
LinWSJT 0.4.7
Rewrote the thread handling so the program is more well behaved, especially
when running for long periods. This could have a bearing on reliability when
running the program(s) for long periods.
Changes of PTT port and/or sound card will now only take effect when the
program is restarted.
Changing the "TX Enable" button to off during a transmit period will now
stop the transmitter immediately.
The patch for wxGTK-2.4.0 has been removed as things seem to be OK with
wxGTK-2.4.1 (I submitted my patch to 2.4.0 and it was accepted).
Upgraded the Moon tracking code to the latest code from PREDICT.
Added Sun tracking to go with the moon.
Added lots of extras into both the common directory (DSP classes) and even
more 'tools' based on them. See the README in the tools directory for more
information.
Fixed a bug in FSK441 where the saved values for the minimum values of
burst length and srength weren't being registered in the program.
Don't show FSK441 messages that don't contain valid text (at least one
space).
Started on JT6M. Transmit works and part of receive works but it isn't
complete so it is disabled at the moment.
Updated the INSTALL file to include more information about the FFTW library
and its two versions.
WS Tools 0.4.8a
Updated my FFT classes to use either FFTW 2.x.y or FFTW 3.x.y depending on
which is installed.
Some small changes to incorporate some GUI programming changes, mostly non
visible.
Moved audio over to the PortAudio library so that I can port LinWSJT to
Windows, also added Windows PTT control.
Removed HB9DRD from all of the files, it no longer exists.
Changed the name to WS Tools from LinWSJT.
Restructured the package to make it build under Windows.
Lots of internal changes, including: re-startable thread control rewritten,
sound handling API changed.
Switching off the Enable TX switch when transmitting aborts the
transmission.
WS Tools 0.4.8b
Fixed problem when decoding files, the EOF wasn't being picked up, caused by
changes for 0.4.8a.
Changed to native sound handling instead of using the PortAudio library. I
just couldn't get it to work very well. OSS on Linux and WMME on Windows.
Converted the PTT and Sound Card preferences to pull down lists of available
devices rather than having to type them.
Sound Card handling on Linux (OSS) is limited to 16 bit mode.
Changed the FSK441 default messages to match the Region 1 IARU recommended
MS procedure. Thanks to Bo OZ2M for that one.
WS Tools 0.4.8c
Fixed a bug in the sound handling on Windows, this would cause crashes when
receiving.
Done a small GUI change for Windows.
WS Tools 0.4.8d
Added an extra page to the screens to show reception in the first and second
periods. An idea from Catharinus PE1AHX.
Allowed for the setting of the directories where audio and text files should
be stored. An idea from Catharinus PE1AHX.
Completely new FSK441 decoder which offers better sensitivity than the
previous version.
Use native Windows functions to handle WAV files on Windows.
Added DF display to FSK441.
Major internal changes.
Removed the intensity display from the main FSK441 graph.
Setting of default values like minimum strength etc. are now to be found
under Preferences instead of the main screen.
All modes have a level indicator bar graph instead of the messages at the
bottom of the window.
