Hi Andy, Chris,
 
there is certainly a good looking trace at 8972 in your screenshot. What is a bit suspicious is that the calibration dash would place it about 1 Hz up, and also that there is another dash appearing at 8998 Hz at the same time.
 
Wishing you all success for this fasinating work,
 
Markus (DF6NM)

Unfortunately taking that screen grab stopped teh SDR-IQ and I didn't notice for a while.  Anyway, after eventually restarting there is not even the faintest indication of a line at the appropriate spot, which does suggest a possibility your QRSS 3600 signal  was detected.
 
Look forward to your next transmission - with slower dot period please.

At what time  did you turn off?
 
Take a look at http://www.g4jnt.com/DownLoad/XIZ_1.jpg  where there is just the faintest line at the right frequency - looking in a bandwidth of 0.05Hz.
 
(The other point labelled is wher ei inject a frequency 10Hz higher at the start to check frequency cal)
 
If it is genuine, and not just a spuron, then QRSS 60 would probably show results.
 
Its still running to see if that just-possible line has now clearly gone.

Thanks for your efforts chaps.

I had definite QRSS-3 confirmation from Dennis M0JXM at 1.5 km but Pete M0FMT at 11 km
had no copy.

I have developed an intermittent short-circuit problem with the loading coil and will QRT now.

I'll notify via the reflector when transmitting again.

Dear Chris, LF Group,

The VLF RX has been running since 1130 - Nothing seen yet.

Cheers, Jim Moritz
