    Hi Luc,

    The RTL2832 based dongles typically go up to around 2GHz, so you couldn't use them for 5.8GHz. You could write a GNU radio graph to receive the 3DR-900 or 3DR-433 signals for telemetry, and that would be an interesting exercise, but you'd need a quite different SDR to handle the signals for a 5.8GHz AV receiver.

    The other problem is receive sensitivity. Those dongles are great fun (I have one and use it for things like ADS-B), but their receive sensitivity is not on par with good purpose built receivers, so they won't give you long range.

    Cheers, Tridge
