WYNN is a station with a few interesting twists and turns. When I came to South Carolina in 1970, WYNN broadcast exclusively on 540AM (daytime only with 250 watts). They were owned by the same company that owned WOIC/1320AM Columbia, WPAL/730AM Charleston, and WSOK/1230AM Savannah. To my knowledge, they were the only stations which broadcast to SC's African American community. Meanwhile, WJMX/970AM in Florence also operated an FM on 103.1 in Florence, WSTN. With 3000 watts, they had the usual "beautiful music" format of the era. WJMX-AM broadcast an unbelievably terrible mix of radio soap operas, MOR music, and religious programs. Other than WYNN, Florence had the worst radio I'd ever heard (WOLS was similarly bad). In the early 1980s, there was a huge change in Pee Dee radio when WSTN's allocation was changed to 106.3, and a new FM station was allocated to Cheraw SC on 103.1. WPDZ (Z103) came on with top 40---a first for the PD. Though they had only 3000 watts they made a sucessful play for Florence listeners. WSTN/106.3 continued to play "beautiful music" with no listeners or ads. But seeing the success of Z103 (which was a fairly awsome station) WJMX-AM was flipped to top 40 (97X). 97X did not do so well against Z103. Meanwhile, WYNN had been sold and, along with some other daytime stations, began lobbying the FCC to allow some daytime AMs to broadcast at night with a low power. About 1985, WJMX/WSTN was able to buy WPDZ who was struggling financially. They flipped their 97X programming to 103.1 )becoming 103X) and began to simucast the programing on WSTN. But this was only a temporary arrangement since 103.1 in Cheraw had gotten permission to change their frequency to 103.3, a class B with 50000 watts. Of course, at that time a broadcaster could only own one AM and one FM within a given market (good old days) and with WJMX-FM now 50000 watts from their new transmitting site in Society Hill, WJMX had to dispose of WSTN/106.3. WYNN, who for years had tried to get on the air at night, and was now having to compete with WWDM and was the natural buyer. WYNN-FM was an instant success, and perhaps surprisingly, WYNN-AM, which had finally gotten permission to broadcast 24 hrs, and with a surprisingly good nighttime signal, also continued to be successful. The ironic thing is that WYNN-FM soon became the undisputed number one station in the Florence market, despte being only 6k. WJMX-FM, with 50k, also did very well for some years, as they and WYNN were the only stations in the PD with comtemporary programming. Eventually, other stations finally entered the fray and WJMX-103X eventually slipped while WYNN remained dominant.
I never had any checks of Z I just always knew for a small town station they were pretty darn good... IMO they did not have the best audio processing, but they made up for it in good on air product... AS for the X being a shell of its former self I think a lot of the stations that me, you and everybody who remember "fun radio" is now a thing of the past... That is another soapbox for another day... CC1
