Birmingham hasn't had an AOR station since 1984, when 95 Rock (then WAPI-FM, later WMXQ, then WYSF and now WJOX) began its segue to CHR I-95. When Rock 99 first signed on in late '88, they mixed a little current rock in with classic rock, but within a year or so it was all classic rock. The first 80-90 docket station to sign on in the market was WWBR at 105.9 (106 the Bear), but it was a 1 kw station licensed to Trussville with its antenna on Ruffner Mountain in East Lake/Irondale. Good station, lousy signal. Within two or three years it segued to Alternative as 106 the X (WRAX's first of three locations on the dial, BTW).
The next (and final) full signal rock station in Birmingham was WRLR (97.3), signing on in '99. Another station hindered by a lousy signal: 640 kw, but at least broadcasting from Red Mountain. All the billboards in the world couldn't help the station. It lasted about two years, until Cox moved WODL (Oldies 106.9) to 97.3 to make way for 106-9 the Point. For whatever reason, no one else in the market tried rock until Clear Channel put the original Vulcan on 105.5, which lasted until they moved WERC's news-talk from AM to FM.
The biggest problem for Birmingham radio creativity is that ownership is basically limited to four corporate monoliths: Cumulus, IHeart, Summit and Crawford. Could you honestly see Crawford doing anything resembling rock radio? And as far as the other ownership groups, they all seem content on cannibalizing each other's formats. WENN had urabn FM all to itself until 95.7 Jamz and 98.7 Kiss-FM flanked them on both sides. WZZK was the market's top banana, so the previous owners of 102.5 went after them, finally dethroning them when they relaunched the station as the Bull and having Patti and Dollar Bill literally fall in their laps. Rock 99 was dominating with Classic Rock until the Point dropped all '80's and became the Eagle. For about the last 20 or so years, Birmingham has become like many mid-major markets: a constant dose of me-too-ism.
