Re: ULF: EbNaut message transmitted from ground loop

[DK7FC <selberdenken@posteo.de>]

Hello Paul, Markus,

Wow, amazing! We've done it :-) 7 characters in 2 hours at ULF. A first 
message from DL > UK.
Think about how long we needed to TX and stack for the 14 dB SNR 
spectrum peak 2 years ago.
Here, without much tweaking, that's the result from the E field only:
carrier S/N: 40.78 dB in 133.5 uHz, 2.03 dB in 1Hz

Thanks for participating in the test.

Good night.

73, Stefan
