Multi-band DDS WSPR Signal Source

This project outlines a PC-less multi-band DDS WSPR signal source that uses a Microchip 16F628A PIC and an American QRP Club DDS-60 VFO. It is capable of 6 through 160 meter operation. Single band operation or multi band transmit scanning may be selected.

Multi-band DDS WSPR Signal Source using NMEA GPS timing

This is the same as the DDS WSPR signal source described above but uses GPS NMEA timing instead of GPS 1 pps timing.  This version only uses bands 40, 30, 20, 17, 12, and 10 meters (the bands that I can autotune).
