<p><font face="Helvetica, Arial, sans-serif">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 look<font face="Helvetica, Arial,
sans-serif">ing to begin compar<font face="Helvetica, Arial,

sensitivity, MDS, and so on.</font></font></font></p>

face="Helvetica, Arial, sans-serif">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 wh<font face="Helvetica, Arial,

programs are in any way comparable.</font></font></font></font></font></p>
