Implements decoding of FST4W messages as (240,50) crc-less codewords.
...
By cascading the full 24-bit crc generator matrix with the (240,74) LDPC code generator, create a (240,50) generator that is used to decode with approximately 1 dB better sensitivity than the (240,64) with 14-bit CRC approach that is normally used. This approach treats the CRC bits as additional parity bits and provides no means for identifying incorrect codewords. All codewords on the list generated by the OSD algorithm have CRCs that match the CRC of the message payload. Codewords are validated by unpacking the message and comparing the unpacked message with the list of stored callsign/grid pairs stored in the fst4w_calls.txt file.

Environment variables to set audio buffer sizes and fix Windows Rx timing
...
The two environment variables:
WSJT_RX_AUDIO_BUFFER_FRAMES
WSJT_TX_AUDIO_BUFFER_FRAMES
each can be defined to an integer number which will be used as the
suggested audio buffer size for Rx and Tx respectively. Not setting
the variable or setting it to zero or less will cause the default
buffer size to be used, which should be a good choice for most, if not
all, systems.
