[hpsdr] A real newbie question

[Pete Smith N4ZR]

I'm one of the RBN team, and am comparison testing the QS1R and Red 
Pitaya receivers with VE3NEA's CW Skimserv. I'm getting some anomalies 
that I can't explain with my 1960's level of electronic sophistication, 
so I'm looking to begin comparing the two receivers for things like 
sensitivity, MDS, and so on.

A very useful tool would be an SDR console capable of running with both 
the QS1R and the Red Pitaya (with software by Pavel Demin).  I have 
SDRMAXV for the QS1R and PowerSDR from your website, but have no idea 
whether the signal level readouts on the two programs are in any way 
comparable.

Does anyone know of a console that will run with both sets of hardware 
and provide signal levels in dBm?

Alternatively, can anyone tell me if PowerSDRmRX PS is fairly accurate 
with its signal strength readouts, or at least consistent from 160 to 
10M?  I'm seeing about a 20 dB reduction in sensitivity of the Red 
Pitaya at 20M and above compared with 40 and below.

TIA
