My 2 cents:
WTAM getting way out at night:
WTAM, like every AM station, is subject to much more interference than ever before. Computers, the new light bulbs, you name it are just making noise all over the AM dial. Plus, most AM radios are so crappy these days, you are lucky if you get a local station, never mind distant skip. So this business that WTAM has scores of regular listeners hundreds of miles away at night is ridiculous. Yes, there are radio fans who tune in with high quality radios hundreds of miles away, but how many people is that? Certainly not many, if they can get the station at all on anything but a lucky night.
Plus, building penetration is terrible for AM. Regardless of how strong WTAM is, try listening in the middle of an office building right downtown.
WKRK:
As some have said, I wouldn't be surprised if CBS commits to moving the sports format to 98.5 as part of the deal to get the Indians.
I don't see them moving without the Indians, tho. WNCX would, in theory, go to 92.3 and probably retain most of their audience (and billing) in the Cleveland metro, since no one else is catering to the audience that wants to hear Kashmir by Led Zeppelin every single day.
