I’ve lurked here for years but haven’t been following the forum much recently. Perhaps one of you ran across our issue and have a quick answer, otherwise I’ll need to spend more time troubleshooting. My daughter has been complaining about on and off NESN-HD pixilation on our HR22-100 since we had a power outage about three weeks ago. At that time I had to reset both our receivers to recover. Maybe a coincidence, dunno. In general we see signal levels here in Southern NH in the 90s for 101, 110, 119, and 103(ca); in the 80s for 99(s) except 0 where the spot beams miss us; and 70s for 99(c) and 103(cb). 103(s) is all over the place from 0-27-97. I looked at the channel references in the FAQ section and found that NESNHD should be on the 103(ca) and transponder 15, I think. I noticed that HR22 tuner one is showing a 4-8 point dip in signal level on T15 compared to the other transponders on 103(ac) but tuner 2 shows a 8-15 point dip, one time dropping down by 20 points to 61. The HR21-100 in another room is showing perhaps a 2-3 point dip and both of its tuners are consistent +/-1. HR22 tuner two transponder 17 signal seems to be low too, in fact they all seem to be lower on tuner two by 2-4 points. Signal levels for other satellites seem to be consistent between tuner one and two. I wouldn’t think antenna pointing or bad cable would just effect one transponder, or could it? I dunno. I would blame the tuner but I swapped cable and BBC connections and have some inconsistencies that confuse me and I need to do more home work. Perhaps someone here can save me some time and point me in the right direction. If its a classic HR22 tuner problem, no use chasing ghosts. I had the antenna system installed in late 2006 using: High Quality RG6Q Digicon Connector Quad Shield Coax Cable Zinwell WB68 6x8 Multiswitch AU9 Slimline dish with a sturdy roof mount. DirecTV Triple LNB I think (three horns) The antenna was originally aligned with the help of an Acutrac 22 Pro signal meter but has been a couple years since it was checked (it did not require adjustment then).
