[QUOTE="archive10, post: 1054206"] Good suggestions. Postcode is valid. Tried swapping the boxes and discovered that the 1010 was pixellating quite a lot on the 2E channel, especially BBC London, ITV and Channel 4 all SD. I think I've guessed the problem. While optimsing skew for 2G channels, I have degraded the 2E channels to a degree where they are borderline. When I tweaked the other day it was evening with clear skies, so channels were just above the threshold of video errors. I dug out the meter, and sure enough, 2E transponders like 10773H are 4.9-5.1 dB C/N ratio, with relatively high BER. Final straw: 11426H does not lock at all, although it's a quite strong signal. I will go and re-skew later to see if I can reach something that works. But the sad conclusion is the 2G and 2E definitely have different and noticable skew, meaning reception on a single, large dish is even more of a compromise these days! Secondary conclusion: The FoxSat error messages are not quite as helpful as you could hope for. Wiring was fine - identical results on all outlets. [/QUOTE]
