Dish QAM Dropping Channels & Guide Info

[MateoHolky]

Have a 70 channel analog system and a full Dish Digital overlay. Over the past 2 months the local channels on satellite 110 have been dropping frequently (several times a day). In addition the guide information will drop and "searching for satellite will appear" - several minutes later guide information will populate. Dish Receiver 351 & HD 811 both encounter same problem. Last night recorded all them signals and were very good. Then all of a sudden the QAM signals on 110's transponders started to fluctuate from 74% to 37%, then just drop to 0 then back up to 70% then go out again. This happened for a good half an hour or so. While that was going on I put the meter on and read signals I completely lost ch.s 107 to ch.113 on the digital all others were the same analog ch.s and majority of digital signals stayed the same.

Any recommendations would be appreciated. Thank you

Try replacing the lnb on the Dish because thats the only thing both the analog and digital system have in common

Has it been raining? It could also be moisture getting into a bad coax connector. Something similar happened to me once.

The problem is happening at multiple properties (all MDU's). The actual receivers in the end users unit (Model 351 Receiver & Model 811 HD Receiver) are dropping the digital per subscription local channels on the digital 110 satellite. In addition the TV guide information will drop and entire channels will drop mid program.

It has rained, but the likelyhood that we are having problems at 5 sites doesn't add up.
