I have recently acquired a Funcube dongle software defined radio. The Funcube dongle is a small USB unit that contains a E4000 Silicon Tuner (radio on a chip), a TLV320AIC3104 Audio Codec and a Microchip 24FJ32GB002 16bit Microcontroller. This small USB device gives me coverage from 64 to 1700 Mhz with some small gaps according to the manufacturers data. You can download more information here: http://www.funcubedongle.com
As a windows SDR RX I am at the moment experimenting with the sdr-radio program that you can download here: http://www.sdr-radio.com
The picture above shows a FM broadcast transmitter in the Oslo area. You can also see the pilot carrier that is used to encode the stereo information if you look carefully
