I too am having problems with LPB. It was working fine before as I was watching the LPBHD channel on Thursday. I am getting good signal on all the other tp's but not getting anything on 12072. Nothing with the dish has changed.
Interesting. I was getting it fine on Thursday too, and it was Friday that I lost it.
Today I took my TV out to the dish so I could see a faster reacting signal meter. I moved that dish every which way (it's a fixed dish, so it's not an alignment issue) while peaked on 12150H, got that transponder as best that I could, but NOTHING on the LPB transponder.
Then, I noticed that I was no longer getting Montanna, which I was getting fine before. Weird I thought, as I was getting the nearby mpeg4 transponder? So I put the receiver on Montanna, and started searching again. With a few adjustments, I was getting a good signal on 12104. The signal on 12150 went down just a bit. Then I checked, and NOW, I was starting to pick up LPB on my TT3200. It was still rather weak, and I wasn't getting it on the Diamond at all, but at least I was getting it, and it was relatively solid, except when the wind blew (which I don't understand, because I'm 90% sure that my view is clear of the tree limbs, and the dish wasn't moving). So I went back out, and tried tuning up even better on 12104. My TV is overscanning, and it was cropping off my quality meter, so I started using signal instead of quality. I made a few adjustments, and noticed a significant increase in the 12104 "signal". Went inside, and had lost nearly everything. Then I noticed that although the signal had gone up significantly, the quality had gone down.
Went back out, and this time tried again to peak the quality as best I could without seeing the numbers, and I got all the channels back, except that LPB was only intermittant on the 3200 and not at all on the Diamond. I figured that was good enough, and quit. So it seems like I must be suffering from some interferrence that's affecting my signal and quality differently on different transponders. I guess that other people have reported thing like this on AMC21, but I thought it was interferrence from the adjacent Hughesnet transponders on the 30,000 SR transponders, which isn't what I was going for, so there must be other interferrence issues on this sat.
Either that, or the sat is closer to my maple tree than I thought. Because the leaves have about doubled in the past week. I think a week ago I was still getting AMC21 on one of my other dishes, but now it is completely gone on my other dishes. So maybe my survey was off. I located where to put my dish via the sun, using the shadow from a power pole, which I assumed was plumb. The tree in question was pretty much in line with the left edge of the tree, and I sited the dish a good 6 or 7 feet to the left of the shadow line when the sun was at the sat's longitude. That SHOULD have worked, but maybe I made a mistake. I hate to cut down maple trees, because I tap them for syrup, but I guess I have more trees than I can tap, so maybe it's more firewood coming up.
