Mark,
It was THE Top 40 station in the early 1970s until around 1976 or so. It was owned by the Hoy family during its top 40 days. They often bought ads in high school yearbooks, and some of the high school kids would have their picture taken with one of the DJs in the control room.
Around the end of the Top 40 era, the Phillips Road studio was burned by a former DJ that had been fired from the station. It eventually moved to a house out on North Monroe Street, which is where it was located during my tenure there.
I'm not sure when the Hoys sold it, but Frank Veihmeyer was one of the owners when I went to work there in 1979. At that time, it was maybe three years or so into the "modern MOR" format.
Mr. V, as we called him, was quite a "hands-on" owner, sometimes doing the play by play for local high school sports.
I started as a board op, running the Larry King show overnights, but moved up to an assistant music director role (no extra pay, no title, they just asked me to and I did it) and a music shift very shortly after starting there.
I have fond memories of WTAL. I loved it there.
