What is with WQDI-LD Channel 20? For the past several days they seem to be broadcasting a good signal, but all channels are breaking up. Is this some kind of satellite or other trouble at the transmitter? I notice that some of the low power TV stations which broadcast from that short tower just south of downtown Cleveland are often off the air for no reason. I presume that this is some kind of turnkey operation, established primarily to collect carriage fees from the shoppers' networks, but isn't anybody minding the store?
