Hi Ric,

your 0 UT transmission produced a plausible decode from my own suburban E-field antenna (attached), but surprisingly nothing from the N-S earth loop at the much quieter DL0AO site.

Best 73,

Two decodes from 00:00 transmission with constant reference phase:

Bielefeld 845km: Eb/N0 +2.6 dB, rank 3399, S/N -31.33 dB in 1Hz;
Todmorden 1413km: Eb/N0 +1.9 dB, rank 9422, S/N -32.07 dB in 1Hz;
Cumiana 371km: Eb/N0 -0.9 dB, no decode, S/N -34.80 dB in 1Hz;
