In the early days of radio, there was a belief that a station should only use as much power as necessary to reach the area it was trying to serve. I believe that Frank Fallain subscribed to that philosophy, moving from 1310 (later would have been 1340) to 880 (which became 910 after NARBA) with just 1000 watts with a three tower array, getting approval in 1940. If he had subscribed to the later philosophy that the more power the better, he might have done what many other broadcasters did and go to 5000 watts full time by 1941. Fred Leonard can tell you, as can many other broadcasters who post here, what a respected station WFDF was when he worked there in the 1960s. Had later owners had more vision, they might have made the format better and had sales people who were more motivated to sell ads on AM. As it was, they kind of let things go and so of course when ABC/Disney offered to buy it, they were more than happy to sell. When CC tried to move WWVA to Bath, Ohio, there was a great outcry to prevent it from moving and CC backed off. WWVA remains in Wheeling, West Virginia, another town in the economic doldrums.
I made the mistake of telling a radio geek that WWJ and WXYT could move downriver and be 50000 watts fulltime, but that both would have to be very directional to do so, and they would be so far away that many areas further North would get much less signal. This particular radio geek proceeded into the CBS Detroit GM's office at that time and told him what I had said. All CBS could hear was 50000 watts. Shortly thereafter, the applications began being submitted. Coincidence? I think not. As I recall, the owners offered to downgrade WMKT if CBS would find them another frequency with the same or better signal to move to. CBS blew it off, and consultants for WXYT proceeded to design and build the oddest looking directional antenna system in North America and probably the world. When WSNQ 900 Gaylord surrendered its license, I had also quickly come up with a plan that would have allowed WFDF to be at least 10000 watts daytime with the existing array. I told too many people about that one also. There's another person who sometimes posts here who could have found another FM frequency for WSUI to move its programming. That could have allowed them to increase the WSUI NIF like WHBY did. So difficult, yes, but impossible, no.
