Maybe your transmitter works better on sunny days?
During rain the antenna current drops not more than 0.7 dB.
However the phase... I don't think so but i will check it during the 75 character message.

I was able to get a decode from just the last four days:

 Day     Eb/N0  Phase  S/N in 2.5kHz
 161130   -7.2  133.6 -61.8
 161201   -6.6  154.3 -61.2
 161202   -7.0  172.4 -61.7
 161203   -3.7  151.2 -58.3

decoded with Eb/N0 = -0.2 dB at list rank 969420.
Just 4 days, very nice. If one would know these days before...
Must have been due to the background noise. Yesterday it was sometimes raining...
As someone said, propagation / QRN is like the weather forecast.
