Hi Andy,

you don't have to reinvent the whole wheel. You may find some useful pieces in
the file mjb002.zip at:

  http://web.telia.com/~u33233109/


Message, timing calibration, DDS frequency/shift, TX probability and GPS baud
rate (NMEA) is programmable via the UART (ASCII) and saved in EEPROM. Output is
either 2-bit binary for "FSKing" a VCXO or direct AD9850 DDS control and a TX
keying line. Runs on a 'F628 and works UFB.
