If I recall, KAER was also a country format for sometime back in the 80's, maybe late 70's. Then they switched to AC, continuing as KAER and eventually rebranded as Y92/KGBY. The rebrand gave 92.5 a more upbeat feel, as opposed to crosstown rival KYMX which seemed to lean softer AC. For a short period, there was even a 3rd AC competitor, KXOA (K-108).
I remember KGBY as a very popular station in the early-mid 90's, with great air talent. I know there are many vets on this board that have "done time" at 92.5 over the years, in one way or another.
Funny how 92.5 returned somewhat to its roots in recent history, dropping Y92 for a KFBK-FM simulcast, and eventually back to country as it currently is. Full circle, I guess.
