I have been having problems with RTN on AMC 9 ever since these channels came on line there.
The NBC news feed channel comes in at 87-91% Q on a Coolsat 5000 receiver, but I cannot get much above 70% from the RTN channels. They usually run somewhere close to 67%. This does not leave me with much of a margin for my threshold signal quality on this receiver, which is somewhere around 65%. I think everything goes completely dark at 63% for a linear Ku band signal.
I have tried different receivers, different LNBFs, altered the dish elevation, motor azimuth, LNBF polarity skew, LNBF positioning for focal distance, altering the TP frequency and symbol rate and standing on my head. Tried eliminating all switches and running a very short cable (6-10 foot) directly from the LNBF and bypassing the motor entirely.
At the same time, with the same equipment (absolutely identical) and only a mile away, just down the hill from my house, my brother is getting these channels in with at least 87% quality, maybe better more often.
Cannot figure it out. The only thing left to do is try one of my other dish antennas or alter the dish location or both. I am just waiting for warmer, drier weather to get out and set up a new installation to test this.
I cannot identify any obstructions that would be in the line of sight that could cause this, but maybe there is something that I don't realize based on and related to the frequency of this particular TP.
If I relocate the dish and the problem is resolved, then I will know that there is some interference problem. If the problem remains, then I will replace the dish. If the problem goes away then, I will know that there is some anomaly with the original dish, maybe it has a strange warp to it. These are the only options that I have left to try.
I am not soliciting for any advice regarding my issue, I am just presenting my findings so that others can compare results. Of course, I would never refuse a suggestion.
Relocating the dish was planned before this problem arose. I have a few trees and the house in the way of satellites like 30.0W and 43.0W so I am relocating the dish for that purpose anyway, if it resolves the problem with 83W as well, then I get a bonus. I will find out then.
