I had a sudden jump in SNR on TP1 today from 13.3 dB to 13.7 dB at 13:51 UTC.
It is still at that 13.7/.6 dB level at 15:15.
The Power level did not change being steady at - 25 dBm.
Sky is 'cloudy grey' but not rain bearing.
It's difficult to see if this ~ 0.4 db rise was seen by others from David's signal logging.
