Since October 2006, about 18 months after moving from Flagstaff, AZ to Dewey-Humboldt, AZ (in order to better cover the Phoenix market), 97.5 FM has programmed many variations of uptempo formats targeted at adults. It started with MOViN’ 97.5, which launched as a Rhythmic AC but evolved to a Hot AC/Adult Top 40 format. By the end of 2010, the station rebranded as Hot 97.5 but generally kept the same format. It flirted with a Dance-leaning approach early in the decade before returning to Adult Top 40. This aircheck appears to have been recorded somewhere in the middle of that most recent transition. The station began simulcasting on KEXX (now KZON)/Gilbert in January 2014, and now calls itself “Hot 97.5 & 103.9”. Many thanks to Steven Ratz for contributing this airchec...
107.3 FM in Washington, D.C. has been Hot AC as “Mix 107.3” since 1990. But in the 12 years prior, it was CHR/Top 40 as “Q107”. This sample from October 1988 – recorded during the station’s “Top 10 at 10” countdown – demonstrates the dominance of hairband acts on the pop charts at the time. Thanks to Robyn Watts for contributing this aircheck. Our sister site, Airchexx.com, also features a pair of Q107 samples: Uncle Johnny, 12/26/83 Celeste Clark, 12/26/85
For over two decades, 99.9 FM in Salisbury/Ocean City, MD has been a Country station known as “Froggy 99.9” with the call letters WWFG. But prior to that, according to Wikipedia, it was a CHR/Hot AC station known as “100 KHI” (that’s the era associated with the logo attached to this post), “Mix 99.9 KHI” (as heard on this aircheck – not mentioned on the Wikipedia article), “99.9 KHI”, and “Power 99.9 KHI”.
At the start of the 90’s, as mainstream pop music became much more fragmented, many formerly “Mainstream” CHRs chose to lean towards Rhythmic/Dance music, while others (such as WPST as heard on this aircheck) moved towards Hot Adult Contemporary. However, by the end of 1991, WPST had evolved into something perhaps best described as “Rock 40”, similar to some of its neighbors in the Philadelphia region, such as WRFY “Y102” in Reading and WSTW 93.7 in Wilmington.
From mid-1992 through the end of 2005, 101.5 FM offered a number of different formats, but always branded itself as “The Zone”. The most mainstream (and shortest-lived) of those formats, as heard on this aircheck, was an Adult Top 40 attempt in 1999, likely the result of competitor KZZP abandoning Modern AC in favor of CHR earlier in the year.
This is a sample of Philadelphia’s Star 104.5 with a Hot AC format, seemingly leaning towards Mainstream AC. The station had attempted a Rhythmic Hot AC format the year prior. As documented on our sister site Formatchange.com, the station flipped to a Rock AC format known as “Alice 104.5” on November 18, 1999.
105.1 FM in New York went through numerous formats in the late 1990’s. This is a montage of the station during a period when, according to The Format Change Archive, the station transitioned from Modern AC back to Hot AC, and called itself simply “FM 105.1”.
Courtesy of the now-defunct mp3airchecks.com, here’s a sample of New York’s longtime Adult CHR/Hot AC, recorded on the weekend before Valentine’s Day in 1995.
Recorded 16 years ago this month, here’s a sample of Philadelphia’s Star 104.5 during its final days as a Hot AC (one with many different variations throughout the 1990’s). As documented on our sister site Formatchange.com, the station flipped to a Rock AC format known as “Alice 104.5” on November 18, 1999.
Recorded 22 years ago, here’s a montage of Dallas/Fort Worth’s longtime Hot AC station, a couple of years after it entered the format. More information about Mix 102.9 (currently known as “102.9 NOW”) can be found at Wikipedia.
