judging by the response to your question, the answer, from this board, would be "no."
I think the kind of one-sided political screeds they broadcast would not benefit from FM-quality audio. It would let you hear the drool sliding off the hosts' lips.
Then again, Toledo is a good example of a market with no really strong local AM signals. Never was. WSPD, with its nighttime array, is probably not much better in coverage than a class-A FM like WTWR. And what's left on the rest of the AM dial, not many people really care anymore. The power reductions in recent years on 1520 and 1560 are a sad sign of just how irrelevant those facilities have become, and how FM really has replaced almost everything on AM, for much of the country.
I, for one, sure miss the old 1470 WOHO - even tho' its signal wasn't really great. But it sounded like it was maintained and processed well. It was an important station for the Toledo of the 1960s and 1970s, and "felt like home."
I wonder if Ken R or somebody still has the different jingle packages, or airchecks from back then, that they could post on online somewhere? Would be fun to hear it again. Especially those July Fourth and Labor Day weekend "oldies" theme packages they used to run, with the one-forty-seven WOHO jingles that sounded like they were from the late 1950s. Guess it's all moldy oldies now. . .
