Hi Paul,

Many thanks! However something went wrong again, the safety function was triggered after about 3 hours! So just 1/3 of the symbols were transmitted. Anyway a big Eb/N0 on your side, excellent! Could it be a faulty segment of the coil, that causes a temporary antenna current decrease? It is a new phenomenon on that coil. It could be also due to the higher ambient temperature under the new housing. I will see wat happens in the next days. With 1/3 of the symbols beeing sent, there will be no decode near Moscow i assume...

73, Stefan

A good decode here as usual:

 carrier Eb/N0: 7.0 dB
 carrier S/N: 21.58 dB in 31.6 uHz
