Others can get into even deeper detail but for years it was sort of a rimshot FM with its transmitter near New Kensington, and studios above a furniture store in downtown New Ken. The owner was Nelson Goldberg. He traded licenses with Milt Hammond, the owner of 100.7 WNUF, which is why WZPT is still licensed to New Ken.
It started off as a Jazz station, then for years in the 70s was free-form AOR. This was the legendary early FM stuff where guys played whatever they wanted for whatever reason came into their heads. Alumni of the free-form days include Sean McDowell, Steve Downes, Jack Robertson, Ron Chavis, Jim DeCesare, Larry Gerson and Bob Stevens (this station was pretty much the inspiration for his new KVE).
They always struggled with ratings, so in the 80s they became more pop, with a format called "Metro Music". Mike McQueen was the biggest of the names on the air from that era. That would also be where the the "Future hits" line most likely came from. Lots of Duran Duran, Pat Benatar, Cars, Devo, all that 80's new-wave pop/MTV stuff.
My recollection gets a little fuzzy after that, as they were sold eventually to Salem (I'm not sure if there was another owner in this era). They became a "Young Country" format called the Rebel, which blended country with southern rock (not that successful then, but almost visionary in hindsight when you see how country music has evolved). They competed not only with Y108 (which was just WDSY then), but also K-Bear on 100.7. Yes, we had 3 country stations here.
Then (and this was definitely under Salem's ownership) they became CHR Energy 105. The afternoon jock was Mike Frazer, and the night jock was the indescribable "Stereo Quad Suzie Wadd". This did not go well, and they became an easy listening format. Ken Hawk worked there then, he can fill us in on more details from that era.
Then they were sold to Clear Channel and under the WJJJ calls did Jammin' Oldies under Clarke Ingram and smooth jazz with Carl Anderson as the PD. I might have the order reversed on those two formats. Then they became Urban AC "The Beat". Clear Channel also got the tower moved to the North Side and the studios into the flashcube on Greentree Hill.
Finally they hired Quinn away from 97 Rock and went conservative talk as their current format, News Talk 104.7.
But as you can see, 104.7 has one of the most colorful histories of any station in the market, and I'm sure several others can add more.
