WBZZ (100.7 FM, "100.7 Star") is an American radio station licensed to serve the community of New Kensington, Pennsylvania. The station broadcasts a Top-40-leaning Adult Top 40 format to the Pittsburgh, Pennsylvania, market. Owned by CBS Radio, the station operates at 100.7 MHz with an effective radiated power of 14.5 kilowatts. Its transmitter is located in Pittsburgh's Spring Hill district and its studios are located west of downtown.


Beginnings as WYDD[edit]

100.7 originally signed on the air in 1963 as WYDD with a power of 10,000 watts in New Kensington, operating as the FM sister station of WKPA, also licensed to New Kensington. In 1967 another FM license, WPGH-FM, was dropped in Pittsburgh at 104.7. The owner of WYDD, Gateway Broadcasting Enterprises, applied for 104.7 and the FCC granted the license. WYDD assumed 104.7, changed its city of license to Pittsburgh, and increased its power to 50,000 watts.

A condition of the grant was that Gateway would have to sell the 100.7 frequency to stay compliant with FCC rules and regulations at the time that forbade a licensee to own more than one FM and one AM in a single market. Because New Kensington was part of the Pittsburgh market, 100.7 was sold to Millvale-based publisher Milton Hammond who used the channel for WNUF. The city of license remained New Kensington with a new transmitter site in Russellton, Pennsylvania. The owner tried to get the call-letters WFUN, but since it was already assigned to another station, the station settled for "fun" backwards, hence the WNUF call-letters. During the construction phrase of WNUF, an agreement was reached with WOMP 100.5 that allowed both stations to increase their power. WNUF received permission to increase from 10,000 to 20,000 watts.

WNUF's studios and offices were co-located with a weekly buy-sell-trade publication called The Green Sheet, both of which were owned by Hammond. Since the building for the publication was owned by Milt Hammond, the station was located there during the period he owned it. The station became known for its Big Band music format. While WNUF broadcast in stereo, since much of the Big Band music it played was recorded before the advent of stereo, many of the recordings were actually a form of "simulated" stereo or electronically re-recorded to simulate stereo. WNUF identified itself as a "North Hills" station. DJs we instructed to ID the station as "WNUF (speak softly and mumble) licensed to New Kensington (say clearly and loudly) North Hills".

Tal Weimer, Bill Trushel, Darrel Deiter, Dino Orsatti, Rich Beno, Fred Moulton, Craig Perry, Ron Miskoff, Larry Kemp and Christian Muro were among the announcers during the days when Hammond owned the station.

In 1984, the station flipped to Soft rock as WWCL, "Classy 101." The following year, the station flipped to alternative rock as WXXP ("Double X 100.7"). This was Pittsburgh's first alternative station. On August 1, 1988, the station was acquired by Pittsburgh Partners (dba Signature Broadcasting). On August 22nd, the format flipped to hot adult contemporary, and assumed the call letters WMXP, with the slogan "Mix 100.7". Waylon Richards served as the station's new program director.

However, with the flip of crosstown competitor WSHH to soft adult contemporary also that year, "Mix 100.7" found it difficult to compete with three other adult contemporary stations and made the switch to Rhythmic top 40, taking on the identity of "Mix Jamz" in late 1990. Rich Hawkins then assumed duties of program director.

While the format switch was successful, it would last until Midnight on December 31, 1992, when, after playing "End of the Road" by Boyz II Men, the station flipped to country as WQKB ("K-Bear" after stunting for a brief period as "K-Garth") (the WQKB calls were adopted on March 3, 1993). The switch came following the sale of the station to EZ Communications (owner of direct competitor B-94) from Signature Broadcasting. The first song on "K-Bear" was "Friends In Low Places" by Garth Brooks. Announcers Bill Webster and Jay Silvers under the "Mix Jamz" banner were retained under the new format.

In December 1994, the station flipped to all-70's hits as "100.7 The Point". The station added 80's music to its playlist in 1996 ("The Hits of the 70's and 80's). In 1998, WKQB changed call letters to WZPT, and added 90's music to its playlist ("The Best Hits of the 70's, 80's, and 90's"). By October 1999, the station would shift to a "Rock Hits" format. WZPT would shift to Hot AC (and change names to "Star 100.7") at 6 PM on June 3, 2000.

WZPT in the 2000s[edit]

During its tenure as a Hot AC, the station called itself "Pittsburgh's Best Variety of the 80's, 90's and Today." One of their more popular music features was "Flashback Friday," consisting of mostly 80s and some 90s music.

Despite airing more of a mix of current music with 80's and 90's, WZPT's format was similar to that of sister station WBZZ ("B94"). In fact, after that station initially dropped the Top 40 format for active rock in 2004, listeners who liked B94 but didn't care for the new rock format were encouraged on-air to listen to WZPT.

WBZZ today[edit]

On January 19, 2010, B94 (93.7 FM) changed again, this time to KDKA-FM ("93.7 The Fan", a sports talk format), CBS Radio announced they merged Star with B94 to bring B94's music onto Star for the listeners to continue to enjoy.[1] In doing so, WZPT eliminated the 1980s, 1990s and 2000s tracks in favor of Adult Top 40 music, playing current and recent current music only. Star added more rhythmic artists such as Lady Gaga, Kesha, and Timbaland in addition to artists such as Shinedown, Kelly Clarkson and John Mayer.

On January 5, 2011, CBS Radio reacquired the WBZZ calls (which they used January 19, 2011) from the former WQSH/Albany, New York and plans to use the calls to replace the WZPT calls.[2]

In October 2011, the station rebranded slightly as "100.7 Star." The station also introduced a new logo.

HD radio[edit]

100.7 began HD Radio operations in 2006. 100.7 HD-1 carried the standard analog format, while 100.7 HD-2 carried a 1980's/1990's hits format dubbed the "80's/90's Flashback Channel" (named after their popular "Flashback Friday" program at the time). When the station rebranded as "100.7 Star" in October 2011, the HD-2 channel shifted its format to include 2000's hits, and was renamed "Replay Radio", which includes heavy references to former sister station B94. WBZZ added an HD3 channel in August 2012, carrying CBS Radio's alternative-talk format, branded as "The Sky." The Sky is also carried on Seattle's KMPS-HD3 and Boston's WBMX-HD4. In early 2014, the HD-3 channel flipped to Top 40/CHR, branded as "AMP Radio."
