Why VHF is bad for DTV

I didn't catch this sooner, but WGVU from Grand Rapids also is on channel 11, and they stayed on 11 for post-transition. So I wonder if the real interference you got was more so from WGVU & no so much from WLFI Lafayette when you watched WTTW on analog 11. Afterall, WGVU may have a null toward Chicago (even now), but the signal can still cross over Lake Michigan. These 2 stations are probably why WTTW didn't decide to go back to 11 well before the post transision, or WBBM-TV taking over 11 for post transition, and instead picked channel 12.

When I emailed WTTW the reply said it was WLFI and they were working with them to fix the situation. While the interference got less, the analog was always a mess. I never had any other problem with digital interference on analog.
It could very well have been Grand Rapids. I recall when I lived in NW Suburban Arlington Heights, I was always able to pull in channels 8 and 13 from Grand Rapids in summer, with nothing more than rabbit ears.
The one thing that amazes me about digital is how sensitive the signals are. For instance I was at the library and I had my laptop with me. I have a digital tuner on it and I was watching TV and the signal strength was in the 90% range and if someone stood in front of the laptop, I'd lose the signal. If a person can block out a signal, it does some pretty odd stuff
Here's another question, I was looking at some digital stations that are on VHF and a lot of them seem to be applying for another signal for a "fill in" translator on UHF. My question is why not just use the UHF as the main channel? Is it that the electric bill is too high on UHF. I was thinking maybe they couldn't find a UHF channel they could operate on full power with? I mean WLS applied to make channel 44 a fill in, then they just made it their full power channel and left channel 7 as the fill in translator. WBBM has applied to make channel 26 a fill in translator. Why not just move to Channel 26 and forget the fill in translator?

I've seen that as well. Second story using a combo VHF/UHF ears/loop. Someone walks into the room at about a 45-degree angle to the antenna and it pixilates like crazy. Walks to the opposite angle and nothing, nada. Walks directly in front (between the antenna and the transmit tower) and no impact. Go figure.

WCIU already complains that the far NW suburbs that they have interference from WKOW. WCCU is also another factor that can keep WBBM from using 26 as the main channel.

Actually, WLS-TV was looking at channel 32 for a translator. Channel 44 only became available after WWAZ went off the air due to bankruptcy. They did put in an application for channel 5, which has yet to go on the air. I just hope WYIN doesn't get any interference from WISH-TV's translator on channel 17. While I can careless about WJYS, WMVS has to make sure their translator on 36 (WMVT's old analog channel) doesn't interfere with WJYS. Now I don't know about Chicago if there are still enough vacant UHF channels that can be used for full power stations. I know 18, 20, 22, 25, 26, 28, 32, 33, 34, 35, 40, 42, 46, & 48 aren't available due to short spacing. Not sure about channels 23, 24, 30, 39, 41, & 49. I don't believe 16 is available due to the frequencies for 16 being so close to 15, which is off limits for TV in Chicago, along with 14 (besides WTVO Rockford being on 16).
