[Elecraft] A question about HDSDR controlling SDR & K3 at same time

[Bob McGraw K4TAX]

Depending on the stability of the oscillator in the SDR, the numbers you 
have now may be good, or may change.   I have an early RSP1a and it 
moves around a good bit.   I don't rely on it for any degree of 
accuracy.  I think it is more temperature related than anything.
