Jay, Rob, LF


Ok, many thanks! I understand the high noise last night.
Rob: my QRG may be almost exactly 137545 Hz, with probably minor variations (at least a few hundred of uHz) due to propagation's doppler effect near the terminator.
Now I'm on air with an unmodulated carrier on the same QRG, then:

QRG: 137545 Hz
Coding 8K19A
CRC 12
5 sec./sym.
3 characters
no time delay
duration: 32 min.

Message repeated hourly, 1st on 2200z, last on 0700z.

Unmodulated carrier from xx:32 to xx:00 minute.

Reports are welcome (noise permitting).


All the best

Riccardo,

As with Jay, no decodes last night likely due to extremely night noise levels here too (+10 to +20 dB over S9).  Believe I did capture your carrier on the SL Spectrum Display from 2230 - 2300 UTC just prior to the high noise levels taking over the band.

The displayed carrier, that could be your signal, was observed at 137544.975 Hz on the two RX systems I ran last night.  Does that correspond to your primary frequency source?

73,
Rob - K3RWR
