>From the looks of it, all you need is a Raspberry Pi, and the RTL-SDR, which is $28.50 on Amazon... so maybe $100 in parts total, but that only works up to 1.7ghz... which most of us probably don't want to bother with. To go up to 6ghz, you need the extender board that apparently can't be bought, so who knows what that would cost.
