Does that mean just 400 MHz or do you actually want to tune it?

These might not be suitable for industrial use, but at least you can see the parts they use:

For an industrial application, we have a possible use for Gumstix computers which involves tuning into certain RF frequencies (i.e. 400mhz), and performing network operations based upon those RF signals.

We are proficient at Linux and C development, but have no idea from a hardware standpoint how to hook an RF tuner to a Gumstix. Can anyone recommend a low-cost part, which can tune into RF and interface with the Gumstix (via USB, or via some other interface), and which we can program?

Thank you,

Bryan
