Perfect decode after 12 UT, Eb/N0 = 24.9 dB.

Apr 2018 13:00 Betreff: Re: LF: EbNaut Test tonight Hi Joe, tried to decode your 10 UT transmission but something is wrong. The constellation looks as if there was only a small amplitude modulation instead of the 180° PSK. So the message I got was 101 stars, and the opds grabber showed a strong carrier peak. Apparently the carrier also started a couple of minutes late and was not perfectly stable. I have now inserted an artificial 137524.5 Hz reference into the fast colour-DF grabber, so you can look at the colour to check your carrier phase. Best 73, Markus -----Ursprüngliche Mitteilung-----
