26.01a from 25.10b
Multiple . characters only one is displayed.
TX if in figs case sp character will be followed by the case shift for the next character. CR or CRLF or CRsp or LFsp or CRLFsp will be followed by a shift character dependent on the next printable character.
Tone frequencies now 250 to 3000Hz previously 650 to 3000Hz.
Ensure that TXM_HANDLE message is not NULL.


25.10b from 25.10a
Initialisation of the interface with Logging apps was done twice now once.
The TXM_MARK and TXM_SPACE message to loggers are now sent to all loggers every 165mS at 45.45 baud


25.10a from 25.02b
FSK timing initialisation fixed
First decimation filter coefficients changed
Text save to file the string match < > characters for Letter and Figure shifts removed.
Improved character synchronisation when a new transmission is received
Improved new signal, new line function
Improved squelch function
Audio input too high, message box added
Audio TX output amplitude increased by 3.5dB
DOOK average/peak ratio improved
DOOK start of transmission stutter removed
Sound buffers size and number changed
Sound card reset on audio system error
AFSK windowing changed from Tukey to Blackman


25.02b Change from 24.10a
New function mute tone that is being QRM'd and copy on remaining tone.
Left click on QRM'd tone in display and tone will be muted and the AFC marker for that tone turned off.
To restore normal decode last click in the middle of the two tones.
A few minor changes have also been made and some documentation revised.

24.10a Change from 24.09b
Increased sound card buffer size
Added CPU AVX instruction detection

24.09b change from 21.03a
Will only work with 64 bit Windows 8 and newer.
Requires a CPU with the AVX instruction set.
Internal sample rate increased to 3000 from 1500 samples per second.
Spectrum display bandwidth increased.
Selective decoder threshold extensively modified with improved noise amplitude assessment.
Repeat string detection re-written works with 2 digit serial numbers.
The asynchronous decoder reworked to reduce character lock time.
The .wav player modified, but needs further work to be fully compatible with all .wav files.
Some message box texts have been modified for increased readability.
Audio TX AFSK and DOOK start up sent 2 letter shifts now sends 1.
pFSK removed from Settings dialogue.

The human and logging program interfaces are the same as before.
