Keen to get ideas or thoughts ??

There is http://sdr.hu/openwebrx  OpenWebRx which runs with the RTL-SDR tuner stick right off the bat. This is a server, and we can use an ordinary browser to look at the received signals.

I did get that working on one of the PineA64+ that I have here, and with the sample-rate of 2048000 it covers the 144MHz to 145MHz 2-meter amateur band all at once. Unfortunately the RTL-SDR itself isn't all that sensitive in this frequency range, but I can see my own transmissions at least Rolleyes

(I see there is a reference to a Line In pair of signals on the AllWinner A64 hardware documentation, pads B14 and A14, now those would be really useful for an SDR delivering the In-phase and Quadrature signal to a sound-card. Could access to these be considered in a future revision?)
