I was fortunate enough to be raised in The City That Bleeds in the 80’s. If you take out 98Rock and HFS, Baltimore was a very stale town for radio. Lots of religion and as Silkie said, lots of classical (3 stations at one point)
There was no Baltimore FM station that played oldies as you’d think of the format in the 70’s-80’s until WQSR stopped their half-baked attempt at Top 40 (they were to be one of the showcase stations for ABC’s Superadio satellite Top 40 format in 1982). I think the owners expected a plug-and-play format and were not prepared to invest the time or money on Top 40 that they had to create and make sound decent.
So around 1985 (plus or minus a year), they dumped Top 40 and went Oldies. I’m not sure if it was automated, satellite delivered, or just a rough start, but it sounded cheap for the first few months.
Around that time (mid to late 80’s), you also had WYST-FM 92.3 which was the closest thing to oldies in the early 80’s (no Motown, lots of currents), WTTR-FM which stopped country around 84 and became one of (early, and few) adaptors of the pre-classic rock “Eclectic Oriented Rock” format as 100GRX. Signal was far worse than today, IIRC. Not really oldies, but it was good for a few pre-British Invasion tunes and some awesome B sides from 60’s rock artists. 95.9 tried R&B Oldies for awhile during that late 80’s timeframe
I coulda swore there was a rimshot AM (perhaps Annapolis) and a DC FM that did Oldies in Baltimore for a couple years before WQSR started. Definitely after WMOD became WMZQ in the late 70’s...maybe I’m thinking of WYRE and Xtra 104. I know DavidEdwardo’s website had a very detailed market report on Baltimore from circa 1988. That will give the definitive answer. It was fascinating reading the report to see 98Rock’s rise in the ratings...they quickly started in the top 5 ratings, destroying WKTK-FM in a matter of months and (I don’t think) has done worse than 5th place overall in the 6+ ratings since signing on in 1977!
