That would be fun to check out. They'll most likely do it at 3 in the morning, but I'd stay up to watch.
For those into catching distant stations, I had a very interesting experience last night shortly after midnight. Normally I only get KMAX-DT out of Sacramento, but last night I was tuning around and I found KVIE-DT on 55.3, 55.4 and 55.5 and KTXL-DT on 55.3. What's going on here? The signals got better and better and KVIE-DT became 6.1, 6.2 and 6.3 once the PSIP info was detected. KTXL didn't quite make it to become 40.1, but it was still watchable on 55.3.
I got a copy of my channel list and started checking the other Sacramento/Stockton channels and guess what? I got several of them! Signals were strong enough to get pictures for the first time from KCRA 35.1* and 35.2*, KTNC 42.1, KQCA 46.1* and KTFK 62.3*. The ones marked with an * were not strong enough for the set to pick up the PSIP info, but the pictures were mostly solid. The signals were good for over an hour before they started to fade away. After it was over, all I could receive was KMAX, like normal.
Using the readings on my Sony XBR4, I've found that a SNR (Signal to Noise Ratio) of 15 or better is enough to produce a picture, but I need about 17 to 18 for the PSIP info to register. KOVR on 25.1 and KXTV on 61.1 were both about 13 to 14... just not quite enough for me to get a picture. KMAX was up to an SNR of 23 at one point... normally it's about 19.
What I don't understand is why KVIE, KTXL and KTFK were showing up on .3 and above, rather than on .1. Can anyone explain this phenomenon?
I turned the 4228 south-southeast to see if the Monterey-Salinas stations were coming in during this period, but I didn't even get a lock. My signals from the stations on the hills above Fremont (14, 36, 48 and 54) were all about normal level. Looks like it was just a nice signal boost for stations to the east-northeast last night.
Did you happen to be tuning around last night, Calaveras, and see any stronger than usual signals up your way?
