There have been reports of the signal changing strenght appearing ( not a huge amount of reports but enough to think something changed ) 11023H for me which was the weakest has gone from 65% SNR to 72% SNR , thats on a 1.55x1.6m with an eco (nomy lol ) lnb. The others have increased also , on my 1.2m motorized the signal is 55% SNR. the floor for reception is 30-32% on my receiver.
First the noise floor. It's not one set level, it changes based on the parameters of the multiplex. For DVB-S2 8PSK 2/3 it goes into heavy pixelisation around 42%, and the DVB-S QPSK 5/6 transponders around 38%. 32% would be a DVB-S QPSK 3/4 transponder.
Second is the increase you are reporting. 7% is quite a big difference and Madridman is only reporting 3%. And I get a shift of about 1% throughout the day, but completely stable 56% since November.
1.1m dish with BU single on 11023H,
1.5m dish, motorised, skewed for the arc, not Astra, with BU single
1.8m Famaval dish, with Invacom quad C120,
So, if what you are reporting is not being caused by your equipment how is it possible it affects you and not me? Well one possible explanation is as follows: satellite stability is 0.1º (?), which translates to about 100 km on the ground. If I draw a circle around my location with a radius of 100km and the whole of that circle has reception at 56%, however much the satellite moves within the 0.1º I'll not see any change in power. But at your location, if 100km north of you gets 50%, and 100km south of you gets 70%, if the satellite moves 0.1º, you will see changes to SNR that I cannot. Anyway, just a theory.
