[Riccardo Zoli <riccardozoli80@gmail.com>]

Hi Paul, VLF

That's great news, dear Paul!

I started a new transmission, with same parameters, looking for a more stable phase...

f = 8270.0033187866 Hz
Start time: 20:00:00 UTC
Symbol period: 60 s
Characters: 2 (repeated)
CRC bits: 10
Coding 16K21A
Duration: 11h,12min
Antenna current: 405 mA

Thanks!

All the best

Successful decodes at Cumiana and Todmorden of obviously
correct message.

Todmorden: Decoded Eb/N0 = +4.0 dB, -31.46 dB in 1Hz,
           rank 0, ref phase -120,-120,-150,-150;

Bielefeld: No decode, Eb/N0 = -3.1 dB, -38.61 dB in 1Hz;

Cumiana: Decoded Eb/N0 = +1.1 dB, -34.42 dB in 1Hz,
         rank 18, constant reference phase.

Warsaw: No decode, Eb/N0 = -5.8 dB, -41.26 dB in 1Hz;
