Thanks for the Walnut Grove antenna info, Chuck. I've saved it for future reference.
The signals I receive from Walnut Grove are way out of line for what TVFool says they should be. They show KQCA way lower than the VHFs, 13 and 31, and that's the way it is under the unusual conditions I had yesterday, but normally KQCA is best. Weird, huh? KOVR has always been weaker than 6, 10, 31 and 58 here. About half the time it's below the cliff edge, while the other four are normally coming in.
Last night as the signals weakened a bit, KQCA started to get stronger again. This morning it was back to being the strongest of the group.
I used to see KCRA in here solid until the KGO translator when on the air, then I'd see if occasionally, but for the past few months I haven't seen it at all. I get some signal on 35 that holds at about 13-14 dB, but I don't know if it's KCRA or KGO that I'm receiving. I have never seen the KGO translator here. The KTVU translator either, for that matter, but I get KAXT 1 and KEXT 27 about 80% of the time.
It's these interesting reception situations that have kept me interested in TV reception since I was a kid back in New Hampshire. You never know what might happen.
