Douglas,
Wait till EUMETSAT are forced to use the E21B backup satellite.
Up there in Scotland, you will be at least 2 dB down on what you are now.
☹
Regards,
John.

Hello Stephen,=========================================================================== Will be interesting to see how they can blame Eutelsat for this. I know 0.5 dB (I am nearer 0.8dB up here) is small but when you are on the periphery of the signal it makes a huge difference. Regards, Douglas.

Jan,
You have a real problem with your system.
With a 110 cm dish in your location you should be seeing an SNR of at least 13 + dB.
Regards,
John.

Hello Stephen,
Thanks for that.
This confirms my now reduced SNR from the higher level this morning.
Best wishes,
John.

And so true! the back-up connection provides a greater sensitivity than the standard up link.

David and Douglas,
It seems I spoke too soon!
My SNR is now back to normal at 15:50 having just come in.
13.1 dB from the steady high of 13.5/6 dB earlier.
It's become cloudy here now but not rain clouds at the moment.
I reported our increases to Ops and they opened a call.
However, KP is away till the 12th so we probably won't get a reply till then.
Regards,
John

Here in Italy the snr at 15.15 utc and returned promptly as described in UNS Eumetsat, at the previous levels of -0.5db less Stephen. -----Messaggio originale----- Da: MSG-1@groups.io <MSG-1@groups.io> Per conto di Douglas Deans via Groups.Io Inviato: mercoledì 6 novembre 2019 14:51 A: MSG-1@groups.io Oggetto: Re: [MSG-1] TP 1 SNR this morning - 09:00 + UTC.

This poor signal issue is even more ridiculous if the back up link gives nearly a dB extra in signal on TP1. However lets wait and see before drawing conclusions. If it does perhaps the prime and back-up should be swapped ! Regards, Douglas.

Hi My signal has been degrading for the last few months used to get 12.4 DB's on TP1 . Now it's down to 11.2 DB on good days I am using 110cm Dish Jan

Needs to hold for a bit longer to verify exact results (and during stable weather) but my rise at the moment seems nearer 0.7 to 0.8 dB SNR up here in Scotland. Frankly not before time. The signal here has been awful for a long time despite my efforts to fine tune the dish which is at an easy head height. Fingers crossed.

All,
I hardly dare to say this but under clear sky conditions my TP 1 SNR on the SR1 receiver is up 0.3 - 0.4 dB from 'what it should be' at this time of day.
The SNR is also rock steady.
Power is, as always, steady at - 25 dBm.
A couple of times so far this morning my SNR went to 13.5 for short periods.
Rather a long way from the good old days 18 months ago when my SNR was 14.2/3 dB.
However, a step in the right direction if someone is tweaking the uplink and/or satellite attitude/parameters.
Regards,
John Tellick.
