Distance 504.6km to Renato Romero's online receiver 'vlf15' at Cumiana via http://abelian.org/vlf > Maybe he even received the EbNaut message? Easy decode from the recording of vlf15 (this is after a stage of vorbis compression and decompression). '58' with constant reference phase. Carrier Eb/N0: 4.2 Carrier S/N: 14.75 dB in 45.3 uHz, -62.7 dB in 2.5kHz. Interesting. At 6140 and 8270 your signals at Cumiana vlf15 are usually a few dB weaker than at Todmorden (Cumiana land path and E-field only). Not so on this occasion. > f = 5170.000000 Hz > Start time: 01.Jan.2017 09:00:00 UTC > Symbol length: 20 s > Characters: 3 > CRC 16 > Coding 16K25A Signal calculator predicts 1.6 dB. Copied '517', constant reference phase. Carrier Eb/N0: 2.0 dB Carrier S/N: 14.31 dB in 53.9 uHz, -62.3 dB in 2.5kHz. Expect Cumiana also got it, will check that next. -- Paul Nicholson --
