[QUOTE="aceb, post: 798004, member: 268811"] Advice from my learned C banders please, on 43.1W I can receive three transponders, 3877V, 3994H and 4000V. Cholusat Sur on 3877 gets upto 50% quality mid morning but fades out completely by late afternoon, the RNW signals on 4000 are available at about 17% quality anytime of day and the Discovery MUX on 3994 appears mid morning but quite weak around 4%Q. Alignment for this sat is critical on the positioner. Here's the odd thing though, 3877 and 4000 although being the same polarity peak 9 pulses away from each other, so far in fact that one has completely disappeared when I've peaked the other one, it's getting on for nearly a degree! A single satellite, signals on the same polarity, no depolariser to introduce oddities so is it a quirk on the dish? It doesn't seem to manifest itself on any other satellite, just this one. :confused: [/QUOTE]
