You mean digital; it would be up to the affiliate / network to broadcast HD over said digital channel. Anyway; run the tool and the select show only DIGITAL channels.
That area is Dayton, OH.
You could always just call your local network affiliate and ask them...thats only 5 phone call.
You could also go to their web site and see what their digi channel number is.
Still doesn't designate HD channels.
As well as each multicast channel.Just click on the station's call letters and you will see what resolution they're broadcasting.
