Software Defined Radio in May issue of Elektor

The May 2007 issue of Elektor magazine has a rather interesting HF Software Defined Radio (SDR) design which covers all bands from 150 kHz to 30 MHz.

It’s been optimised for receiving DRM and AM broadcasts but is also suitable for listening in to the world of amateur radio transmissions.

It is USB controlled and uses your PC's sound card as the
A-D converter.
