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

Solid copy here, obvious correct decode.
Carrier Eb/N0 +1.0 dB, BER 39.1, constant reference phase.

S/N: 17.03 dB in 133.5 uHz, -21.72 dB in 1Hz, -55.70 dB in 2.5kHz
