[hpsdr] Setting freq on PowerSDR.

[KF6C]

Thank you for your help John.

I had no idea it is that easy to control PowerSDR from an Arduino.

I now have a knob tuned  SDR with all the feel of a 1960's radio or a 
1960,s radio with state of the art panadapter /waterfall display.

It consists of a Mercury/Penelope/ Hercules SDR contoled by a 1966 
Eddystone EA12 tube/valve receiver. I have removed the ground lug from 
the EA12 and temporarily replaced it with a BNC line coupled to the VFO. 
The Arduino frequency counts the VFO and outputs the result to CAT.

I would like to reduce the latency a little but it works quit well. It 
makes switching between playing with old radios and the state of the 
art  real quick.

Thanks again.

Brian KF6C.
