Hello All,

I see from my own readings and David's across Europe signal graphs that most of us have seen a step drop in SNR/LM at 13:00 UTC today.
My SNR is down from 13.5 this morning to around 12.5 dB with some cloud now.

I headlined this in my daily report to EUMETSAT.  Previous responses have suggested that as long as the signal is above the minimum agreed level there's no need for action (by EUMETSAT).  They are in the hands of their service provider, of course, they don't run the uplink themselves.

============================================================================ Thanks David and I do agree. Nevertheless up here where the signal is more marginal it is annoying that there is an additional 1dB (which I lost yesterday) available. We know the back-up station can provide good improvements for example.

My guess is that this signal issue is related to the Hotbird 13 degree test which is due to complete about 14.00 UTC. In fact I have just checked and the signal level appears to be increasing again, although I will need better weather to completely confirm.
