KCMO-FM isn't likely to make too many changes. It's already one of the top-3 stations, and it's become an even stronger 25-54 player since it dropped most of the 60's to become a 70's-centered playlist in '06. I do agree, though, that Cumulus, if anyone, is the most likely to make a move on picking up the AC format. However, I think they'll either kill Jack or 103.7 The Dam.
KMAJ used to always put in a really good signal to my old house in Shawnee. I could get it on my clock radio in my bedroom, and a couple of the girls I worked with would listen to it at work at the office in Lenexa. I don't know, however, if it's a viable Kansas City station. By the way, when I first moved to Shawnee in '97, KMAJ was almost a CHR at night. It ended up picking up Delilah and just sounding like another AC by the summer of '98. I could actually get Delilah on 3 stations at that time because I also could pick up KESY 97.7 out of Omaha. My ex was an AC listener and might have liked that nighttime format on KMAJ, but she never tuned north of Q-104. Besides, I'm thinking KMAJ was already running Delilah at night after she finished her extra semester of college to join me. She also liked 102.1 The Zone and would tolerate Mix and KFKF.
