Hi Riccardo,

Wow, that's amazing. 26.5 dB in in 34.7 uHz. We could transfer 100 
characters in one night! It will not be that easy on 8270 Hz :-)

Also thanks Markus for the decode.

73, Stefan

PS: How far could this signal travel! We are missing RX stations everywhere!

You see now that VLF reception is possible from your QTH and you just
need to get less noise on 8270 Hz maybe. But the system and
frequency+phase stability is there! This weekend there may be a chance
to pick up something on 8270...<br>
