Getting Started with Software Defined Radio

Software defined radio is a bit like having one of those old ham radio’s, only at a fraction of the price. The USB dongle costs so little it’s really worth it just to have a look, and there are so many things to do with this fun device.


Software: has a selection of software.

So far I have been able to pick up AM and FM radio stations, as well as having a look at the WiFi band, and receive my son’s toy walkie talkie and RC car transmitters.
