A few weeks ago, I started having signal strength issues with my main receiver...a VIP722. It seemed that whenever I'd exit watching a DVR recording and go directly to "Live TV", I'd get a complete signal loss error message. I'd reboot, and sometimes this would remedy the problem for a while and sometimes not. Often, I'd get a message saying that the HD channel could not come in and that the receiver was defaulting to the SD channel. I'd check the signal strength and from what I could tell, all was OK. What's "OK"? I had a tech several years ago tell me that anything over 50 was adequate. So...last Friday, I had DISH come out and the first thing the tech did was re-peak the dish. He told me that there was a "top bolt" in the mount for my 1000.2 that "a lot of techs miss" and that the dish had "slipped down" a bit. After adjusting it, he told me that my signal was "70 or above". All seemed to be working well when he left, even though there were questions about the strange error messages that were coming up on the receiver during that past week. I'd run a check switch test and I'd have the receiver tell me it found "38 of 38", instead of 4 of 4. Anyway, the same issue occurred last night again. I couldn't get any HD channels. I ran the "Point Dish" test and on transponder 17, I was getting a signal strength of 75 on 110, 63 on 119 and only 35 to 40 on 129. I'm about 30 miles north of Milwaukee, WI on the western arc. My questions are these: 1. Can I safely assume that my HD channels are on the 129 satellite? 2. When aiming the dish, does a tech try to get the best signal for all 3 birds, or can he or she "prioritize"? In other words, is it possible to get the highest signal on 129 at the expense of a lower signal strength on 110 or 119? I have a feeling that I'm going to need to get a tech out here again to see what exactly is going on. DISH agreed to send me a new (I'm assuming "refurbed") 722 last night, so hopefully I can exclude the receiver from being the problem after I install that. Oh...and yes....I am aware that the Hopper receivers would offer me much more, but for now anyway, I have my reasons for wanting to stay with my 722, 622 and 211K. Thanks in advance for any help/advice the members here may be able to offer.
