<DIV>Hey Pete,</DIV>
<DIV>I don’t know about any common software that runs on both. I have been
messing with the Red Pitaya for a while now. I have run it with SDR#,
HDSDR, GNU Radio, and a while back on PowerSDR, but that’s no loaded on the
“new” bench computer.</DIV>
<DIV> </DIV>
<DIV>I’m getting ready to do some analysis of the RP, and have been finding and
fixing my Rx test equipment accessories. I just did a quick test using a
good, modern signal generator. I found that on SDR# version 1337, with the
generator set to –93dBm, I get a signal about –100dBm on the RP and SDR#.
This level is consistent from about 2MHz to 30MHz. So, the RP seems to be
pretty flat across HF.</DIV>
<DIV> </DIV>
<DIV>I want to do more testing at more RF levels, and particularly LF.
This is just a quick note, as everything was already running on the bench!
Also, don’t run the latest RP ecosystem with Pavel’s software, as there is a bug
in the latest ecosystem vs Pavel SW. If you run that combo, you will get
multiple spurs around the main bang.</DIV>
