KCOH call letters stood for "Call of Houston," according to the history of a Houston broadcasting web site created by one whom I cannnot remember right now. I'll find out, or Chuck Tiller will know off the top of his head. KCOH started out as a "beautiful music" station.
I once mistakenly assumed that the COH stood for "City of Houston" and was once owned by the city, like WRR in Dallas was. I was completely wrong on that.
What could be done with KCOH? Well,, it's A.M. Your choices are right-wing talk or religious or sports. Of course, the obvious answer to me is left-wing talk, since we don't have one. Could it make it? It would be tough. Filling up the program schedule would be easy. There are plenty of syndicated left-leaning talkers out there. Just put in your local guys for morning and afternoon drive. Ah, but it would need someone with pockets deep enough to get it going.
I know what you righties are going to say. Air America tried that and didn't succeed. The problem with Air America was that its money came from people who wanted to get a quick return. Also, Air America spent its investment money BUYING low-rated radio stations rather then seeking affiliations.
We'll that's my opinion. KCOH is currently in the best position right now to succeed in that format, I think.
