We have one FUNcube Dongle Pro v1.1 on loan from @ansi.
The receiver is a SDR unit capable of being tuned between 64MHz and 1.7GHz.
There's control software for the tuner, amps and filters of the receiver.
The tuner itself will register as a sound card and capturing data is done using the usual means of audio recording. Decoding is entirely software based.
Note: the funcube dongle is not suitable to receive ADS-B frames since the shortest pulses are 0.8us which is far below what can be sampled at 96kHz.
