Its a sunny breezy hot day here in Lexington KY. I have Dish 2 rooms (622's). Both will give me drop outs on occasion, especially on the HD channels. Right now, I'm watching MGM and I'm getting a drop out about every 20 sec's. I've checked cables in back on both tv's, did hard reboots. Dish has been out twice; the first didn't really do anything. He just checked the cables in the back and did a check switch and reboot. The 2nd tech was here longer. I showed him something I had recorded on DVR to prove it was dropping out because it would not do it while he was here (of course). He mentioned something was unusually low! He changed the lnb and came back inside. He said, hmmm still low. He waited around to see if it would happen again and it didn't (of course). As far as my Dish itself, signal really has never been an issue for the almost 4 yrs I have had Dish (no trees blocking and I'm on a small hill) until I upgraded to HD back in January of this year, I started noticing on BOTH tv's this happening on occasion. I do know I have seen it on ONE SD channel "CHILLER" my roommate said he saw it happen on another SD channel. It is so sporadic, but mostly its on HD. Forgive my lack of knowledge. Any suggestions and did I leave any vital info out?
