WRRK History:

WLOA-FM "on the air" Late 1947

Broadcasting in Stereo 1962

WLOA-FM was owned by Bill Matta of the Matta Broadcasting Company. The studios were located on the top floor of a Desoto/Plymouth Dealership in Braddock, PA. The Broadcast Tower was visible from the top of the Thunderbolt Roller Coaster at Kennywood until a fierce wind storm in October 1954 knocked the tower down.

WRRK's previous formats and call letters included Easy Listening and Adult Contemporary as WLOA-FM (it was also simulcast on an AM station when it was WLOA, which is now All-Talk WURP) and Soft Rock as WFFM and WMYG. In 1985, the station known as WHYW (since 1982) began featuring Classic Rock from 7 pm to midnight while retaining the Soft Rock format from 5 am to 7 pm and playing jazz overnight. They maintained their "Y-97 FM" identity during this time. In March 1986 the station went to Classic Rock full time; the calls were changed to WMYG and they began referring to themselves as "Magic Y-97 FM," shortening it to simply "Magic 97 FM" later that same year. In 1991, the station switched to a current-based Rock format, and the calls were changed to WRRK. When the station was bought by Legend Communications in 1993, the Classic Rock format was resurrected, but the station retained the WRRK call letters.

Here is what PBRTV.com has to say about WRRK

The station basically held the same basic format under the names of "WMYG/WRRK Magic 97" and "WRRK 97-ROCK". Nonetheless, after years as a classic rock station, the format was changed in November 2005. It is the sister station of WLTJ. The original studios were a small building in Braddock - a small town east of Pittsburgh. In fact, the Legal ID still has Braddock as the city of license, but moved to 7 Parkway Center when the current owners -- Steel City Media -- bought the station. In the days when the station was in Braddock, it was WLOA-FM and AM which took on an Easy Listening style sound. In the late 70's, FM-97 signed on playing more of a Soft AC sound under the direction of McVay Media Consultant Dave Popovich. The format was tweaked to a soft rock geared to women and given the nickname "Fem-FM". A callsign change was in order and WFFM Rockin' Easy was the name. WFFM was one of the first stations to give away $1 Million to a single listener. The contest flooded Ma Bell's lines as they took the 97th caller for the contest. Most of them were heard on the air. In recent times, many a listener will recall hearing Jimmy Roach (WOGG) and Steve Hansen together in the morning on the old WMYG. They were first at WDVE and then to Florida before their gig here. They were let go when the ratings and their performance went through the roof! Jim Quinn moved to RRK after having been fired from WBZZ where he hosted mornings with "Banana" Don Jefferson. After Quinn and Rose moved to 104.7 FM in 2004, the station went with syndicated "Bob & Tom" for mornings. In late 2005, WRRK was changed to "BOB-FM" and a format which plays a very eclectic mix of music. Many thought the new "Bob" format wouldn't take hold, but the ratings have proven differently.
November 1, 2005, WRRK switched to Bob FM 96.9. "We Play Anything"    

March of 2007 WRRK started broadcasting in HD
