Thank you very much for your info and ideas. I did what you said about resetting the antenna setup, and put in a random zip code (happened to be New York City), which, coincidentally also has an 11.1 & 11.2, and then I was recieving programming on those 2 channels. Of course, the guide then showed the programming for New York's channels, but I was recieving the local 11.1 & 11.2 signal. So, then I went back and did another reset and setup with the local zip, and now I have all the locals in the list, in the guide, and programming, with the exception of 11.2.
I read your post in this thread from last year that discussed the randomness, and flakyness of 11.2, so this must be a spotbeam issue. While trying different things, I put in Spokane's zip code, which also has 11.1 & 11.2, and like I said, Spokane's channels show in the guide, but I can actually watch the local 11.1 & 11.2 (KFFX & KFFXDT2) through the DVR. Back to the local zip again, and I am recieving 11.1, but not 11.2. It says it is searching for signal on the off-air tuner, and then there is a code, I believe it is 796? Can't remember for sure.
But, when I go to the signal meter, it shows the same signal on 11.2 as 11.1. Anyway, just FYI, I have 1 amplified antenna, split to all 3 DVR's, and then 1 leg split to 1 TV tuner, I have nothing diplexed, not run through the SWM, all RG6, the signal strength has been sufficient for a steady picture, and has been this way for years. The software version on all 3 DVR's is 0x62c. Networked via DECA, CCK SWM8, 4 way splitter.
I am going to try shutting down all the DVR's and resetting the SWM, as I have not done this in a while, and see if that helps, but I am guessing this is a D* issue, and will not be resolved by anything I can do.
