Steve Belter, N9IP has put together an excellent tutorial on setting and
using HDSDR especially with the FCD.

Subject: [amsat-bb] Sample ARISSat-1 recording with Funcube Dongle
> Hi All,
> I've been recording quite a few passes of ARISSat-1 using the Funcube
> Dongle (FCD) SDR and the HDSDR program. The resulting file from a 10 min
> pass, recording the whole FCD passband, is about 250MB. Below is a link
> to a sample from this morning. The bird was in the sun, so it's
> transmitting continually, making things easier.
> This sample isn't perfect, but it's pretty good. It was made using my
> "low" array, which is a M2 2MCP14 configured for RHCP. There is a good
> ARR preamp at the antenna. When in the clear, it's quite good--but much
> of the pass is through the house and/or trees....

> The file is BIG, nearly 250MB...
> Have at it :)
