I had to move my dish because DirecTv's techs pointed it at my tree in the fall and then were surprised when the leaves blocked the signal. Needless to say I have it moved to a new location, and did it myself since my local tech tried to bilk me for $100 to move it twenty feet. Anyway, I have new cable to make sure it was good quality and the cable channels are coming great. I checked the transponder strengthes and I get 91-100 on most of the transponders, but 4 is zero, 12 is at 62, 20 is 58, and 28 is 88. I am trying to provide as much info as you need. Please feel free to ask if you need anything more. Its been that way for at least 4-5 days so I don't know if resetting the local channel authorization would work or not. Oh and please understand that I am a little inexperienced on how this all works so please dumb down your answers a little, no acronyms!
