I noticed that TP1 on 119, which is a spotbeam for some of my locals, is in the low 70's. It used to be low 90's before. All other signals on all TP's and satellites are still the same as before. This one is the only TP that has dropped 20 pts. Also not related to weather, as the sun shines here since weeks every day. I wonder if somebody knows what this could be. Haven't had any lost signals yet, just curious what causes it.
