DDS Based QRSS Beacon

Based on the design by Matteo Campanella, IZ2EEQ who's article appeared in QEX Magazine.

Lots of insprisation and support from Colin G6AVK and the QRSS Knights Group.

It is based around an Analog Devices AD9851 DDS and a PIC16F628. I designed the PCB using Eagle.

I am currently in the process of designing a new multi-band version with new software, if you have any tips or can help with PIC software development, drop me an email.
