I've been having a strange problem with my big dish that I can't figure out. The sparkles start showing up on G5 and west of G5. Everything on G9 - east is perfect. I thought it was trees but now I have a good sky, next I tried replacing the LNB, no effect. It starts happening on the higher channels as listed below. What's left? I've tried all of the manual skew adjustments on the IRD menu to no avail. Listed below are some of the channels affected. I've got a TRX1800 toshiba IRD which used to work fine, it's about 9 years old. G5 transponder 5 = 10.0 quality perfect. G5 transponder 22,23 Cnn and A&E = 5.5 sparkles F3 transponder 5 (i think) Lifetime 7.1 F3 23 E! 5.3 F4 1 7.1 F4 23 5.3 What I don't understand is why the satelites east of G5 don't have the same issues with higher number transponders. any C-Band guru's out there still????
