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 1.5= millihertz FFT resolution. It definitely wasn't there before ;-)
