Well that's its limit. 8137Hz sampling, 2M FFT for a .0039Hz bin size. Will leave it running in the hope the frequencies displayed are as it says they are - not in a position to do a frequency-cal run at the moment.

Nothing here. But with 15dB S/N at Jim's in a tenth of the bandwidth I'm looking it, and at at least twice the range, probably not surprising. I'll try going narrower, but have never tested the SDR-IQ at these limits so not sure how the display / calibration holds up.

Dear Jim,
That looks very promising.
The balloons are still up and I'm back on QRSS 600.
I'll keep the TX going for a few hours or until the aerial comes down.

Dear Chris, LF Group,
I seem to have a trace on your frequency - see attachment. SNR is currently around 15dB with 1.5millihertz FFT resolution. It definitely wasn't there before ;-)
Cheers, Jim Moritz
