Hi Paul,

yesterday the QSB smeared out your carrier by about 20 mHz:

I tried to decode four sequences before midnight, and after a couple of mHz center frequency tweaking all of them came out alright:

Sun. 2016-02-28 477690 Hz
start  car. sym.
 UT    dB   dB
23:00  8.7  4.1
23:15 10.0  3.9
23:30 12.9  6.8
23:45  8.8  2.6

Tonight the peak looks a lot narrower, resulting in easier decodes:

Mon. 2016-02-29 477690 Hz
start  car. sym.
 UT    dB   dB
20:45  4.1  2.2
21:00 13.1 10.8
21:15 15.0 10.2
21:30  8.6  6.4
21:45  6.6  3.0
22:00 16.1  8.1
22:15 16.2 10.7

Hope that Domenico will be able to see some of your signal!

Best 73,
Markus (DF6NM)
