WLS Chicago ABC 7 is making changes

For those of you who have been having problems with WLS Ch 7 in Chicago, things may be getting a lot better.

WLS has announced the following:

Their UHF transmitter on 44 is scheduled to come online by this weekend.(Oct 30) It will be operating at a temporary power level of about 350 kW with a directional antenna while the permanent, higher power facility with its omni-directional antenna is constructed (no ETA indicated).

In conjunction with the powering-up of UHF 44, the temporary authorization that allowed them to double power on VHF-7 will expire at midnight Saturday and they will be dropping back to only 4.75 kW on that signal.

This means that deep fringe viewers who have been getting WLS on channel 7 may lose that signal. It will be necessary to re-scan (with the attendant problems that may bring) to see if you can pick up the UHF-44 signal with their UHF antenna when it is activated. At only 350 kW, the temporary UHF signal might not quite make the trip leaving some without service.

Don’t forget the “double re-scan”.

  1. I’m lost. I live in Palatine and for the past week we can’t get any of the ABC digitals 7.x’s. It was like this for months at the begginning of the year. Was fixed for several months and now the past week or so it’s again unwatchable. What’s going on?
