I have recently come across a very interesting DDS kit, capable of generating up to 200 MHz, and with an option in the PIC controller that displays one quarter of the frequency generated. Perfect for a DC receiver with a 74AC74 that follows the DDS board to generate the quadrature LO signals. I have ordered (and received, but not tested yet) one kit, pre-assembled (I don't like working with SMD components...). The URL is http://www.radioamatore.it/i0cg/add9951.html 73 Alberto I2PHD Yahoo!
