Channel signal loss on 77W TP21

[dare2be]

I've been getting intermittent channel signal loss on my local channels on 77W transponder 21, but only when changing to one of the channels...once it is tuned in, there are no problems. Any ideas?

System Info - Details section shows the log of signal losses. There are about a dozen with the following codes. Is this LNB drift?

11-11-11
11-12-11
11-22-11
12-12-11

I'm getting 71 signal strength on 21 transponder on my eastern arc 1000.4 sat dish and it is 10:23pm central time here in Texas.
But if you are getting those codes it might indicate you are losing the signal ,due to either lnb drift or the dish has moved from it's previous angle for the 77 sat. ON the 1000.4 sat dish I had to hit that sweet spot between both 61.5 and 77 sats ,using the azimuth cam to get it peaked for both. I did that back in 08 and haven't touched it yet ,but my dish is on a pole out back.
