GE Markus,

Frequencies for Op8: 137600-137700. Therefore transmitting remained "unnoticed".
The trace of your op32-signal was visible in a 3s-window.

Hi Graham,

yes, I've been testing two rounds of "homemade" opera-32 on 137.590 kHz, 0.6 W 
ERP. Also had a go at opera-8 in the middle (ending
22:25) which apparently went unnoticed.

PSK reporter surely has no idea of where I live, and for some reason it 
erroneously located me at IO91UX (incidentally the QTH of
M0FMT). Thus the distances on the web are not correct.

BTW is it possible to read the SNR off pskmap as well, or only from the application? 
-39 dB on Opera's "slightly biased average
power scale" would mean -35 dB carrier vs noise in 2.5 kHz. Which would be +14 dB SNR in 
30 mHz, ie. a comfortable "O" in QRSS-30,
and probably readable in QRSS-10 as well.

Best regards,
Markus (DF6NM in Nuernberg JN59NJ)

PS  just noticed that TF3HZ has managed to capture my second op-32 transmission 
(ending 23:07). This should be about 2540 km or so.
