channel 7 problems in Windy City

[Kevin Vahey]

Chicago also has been having major problems with signal since moving
from Ch 52 to 7 last month

I know people who live close to downtown and are getting nothing.
WBBM-DT is also having problems but they have never had a good digital
signal to begin with.

I talked to an engineer at WLS and he said they are pushing to move
back to UHF permanently and they are very aware of the problems in
Boston.
