Yes Eddie, you got it! The two-letter decode you sent by private mail is perfectly correct. That's more than I dared to hope for!

Thanks a lot!

I wonder if Jacek, Eddie or Stefan might have been able to decode this one as well? Considering message length, duration, and ERP ratio I figured I'd have a chance with anyone who received the DK7FC message with 5 dB or more Eb/N0.

Hi Marcus

I was wondering if it was possible, so I guessed at what would be needed and I have a decode.
I am fairly sure that it is a positive. Really good going considering I can't see any trace from you.
