I set up a new triple lnb dish with a ts-160. All worked fine for a few weeks, then HDNET started breaking up and was finally gone. Figured it was trees leafing out so I moved the dish, get 90-100 signals on 101 and 110 sats, zero on 119. Tried complete range of tilt adjustment, nothing. Also, when I try an auto-detect for dish type with the ts-160, the detection fails. The auto-detect worked when I first set it up. I believe the lnb is okay because I was able to tune in to the 110 sat with it by shifting the azimuth 10 degrees. BTW, I had Directv send a tech out with the understanding that I would pay if the problem was related to my install, but if it was an equipment issue no charge. The tech told my wife that we were getting the 101 and 110 satellites but not the 119(thanks for that info) and I had to move my dish. He also said the HD channels were on the 110 anyway.(That explains why I get searching for signal when tuning to HDNET or HBO-HD) Any ideas? Is it the ts-160? the multiswitch?
