Not quite sure what you're trying to suggest... There is no 'magic' to a phase continuous oscillator. Any single oscillator whose frequency is controlled by adjusting the frequency determining el
If you want a stanadalone beacon then http://www.g4jnt.com/beacons.htm gives info on WSPR transmission, and includes PIC code for controlling an AD9852 DDS and transmitting a pre-stored WSPR mess
I find the SDR-IQ a superb little box, and is better than any comms reciver I've used over the years. And that applies especially to several professional, including early generation digital, receiv

My 503.7 / 503.875kHz beacon has moved onto a restricted transmitting schedule. From today, it is operated on a timer that comes on at 2000z running the Tx overnight, and switches off at 0500z. Dur
