In Chicago, ME-TV also is carried by a full-power station as it's primary signal.
Sorry, but ME-TV's primary station(s) WWME, either analog OR digital, are NOT full-power. WWME's digital ch.39 was Chicago first LP digital station in the market.
It simply got picked up by BOTH DirecTV & DISH because, as you already stated, Weigel is a tough negotiator - & even got BOTH DirecTV & DISH to carry WCIU-26 in HD as well. (mostly due to all the local sports it carries in HD, namely some Cubs & White Sox games)
