The PIC-EL is a PIC project/demonstration board described in the February, 2010 QST. The PIC-EL in combination with the DDS-60 daughter board make a nice multiband QRPp WSPR transmitter.

A modified version of AA0ZZ’s excellent signal generator program to include WSPR operation is located at http://www.knology.net/~gmarcus/. Capabilities include 160 – 6 meter operation, LCD readout, internal timing, VFO control, and a frequency calibration routine in software.
