ULF amateur success

Stefan DK7FC has successfully decoded his radiated signal at 65km on 2.97kHz. He refers to an attachment that is not included here.

"Hi ULF,

My post-processing of the 4 day recording is still running, almost 50% of the data is shown on the spectrograms now.
I'm happy to confirm the successful decode of a
5 character EbNaut message over 65 km on the 101 km band, with a BIG SNR! It's the one which started on 08.DEC, 7 UTC. First there was no decode until i found that i made a mistake, the actual start of the transmission is 6:58:40 UTC, an offset of -1 symbol.
Capture in attachment. I also attach the wav file, if someone wants to play with it, the size is very small.

73, Stefan"
