Getting to be too many wires involving the sdr stuff, so I'm going to try to combine the up converter and the sdr dongle onto one assembly to reduce the wires needed as far as powering them goes.  Both boards have to be connected to the PC to get power, but the up converter doesn't transmit USB data. The sdr dongle has to be connected to the PC because it has to xmit data back, so I want to snatch 5V from it's board and power the up converter from it. I hooked both of them to a lab supply and found that the dongle draws ~110 mA, and the up converter only draws ~ 10 mA. The PC USB port should provide up to 500 mA. Stay tuned.
