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. 73 Johan SM6LKM Andy Talbot wrote: > I'm looking at code to generate a WSPR signal directly from a DDS/PIC > combination controlled from GPS timing
