1480 is NOT designed to be a radio station for Dayton, Eaton, Piqua, etc. Neither is/was 1160 AM. It's designed to be a local for Cincinnati.
It is what is known as a Class B AM radio station (up to 50 KW day). It doesn't reach the Dayton area very well because of it's high position on the radio dial. They must protect class A stations by modifying their signals at night. It's been too long ago since I worked there to remember exactly who the station protects.
Nonetheless, the daytime signal, while not quite as good as 1160, should be serviceable over most of greater Cincinnati. In the 70's the station's signal was very good in the daytime from the Glenwood Avenue tower site, but crap at night. (I would lose it two exits up I-75 north going home at night.) I know the towers and transmitter were moved, and power lowered as a result. Whether something can ultimately be done to improve this, I do not know.
Even so, I wish them the best. WDJO does a good job at what they do. I'm sorry to see the WCIN calls go away...but I guess they don't mean much anymore down there.
I was the News Director at WCIN the night of the Who concert tragedy. I was working in the newsroom after returning from the scene. We got a phone call that night from the BBC in London. I fed them tape of the eyewitness interviews I had done and agreed to be interviewed for their morning show. At the end of the conversation, I asked the gentleman from the BBC, "How is it that you chose to call us for information?" His reply? "We called the overseas operator and asked them for the names of radio stations in Cincinnati. We heard your call letters...WCIN...and figured you had to be one of the biggest stations in town."
I let him go right on thinking that, of course!
