That would be Z-93.7 out of Ocala. I guess Gainesville had 3 CHRs at the time - Kiss 105.3 (still around today), Z-93.7, and I-100.
I'm surprised Kiss 105.3 still doesnt reach Ocala after all these years.
Anyways, you've got a good memory - I too distinctly remember Z-93.7 playing some Country.
There were a lot of great CHRs back then. BJ 105 was an amazing CHR/Pop for Orlando, and very similar sounding to Miami's Y-100. There was also Y-106 (today's XL 106.7) though its ratings were nowhere near those of BJ 105.
In the Disney World area (Lake Buena Vista) you could always pick up so many CHRs. It was like a CHR amusement park. LOL, think about it - even today you can easily pick up 93.3 FLZ and 107.1 A1A alongside XL 106.7 in the Disney World area.
Oh, another thing I remember about I-100 was that it was very big on Recurrents. Its powers were usually songs that were starting to drop on the national charts. It was also very Rock friendly. I remember them being all over songs like "Edge of a Broken Heart" by Vixen, and Europe's
Superstitious". Their slogan was "The boss of Daytona".
It was a bit confusing though b/c you in 1988 had Y-100 in South Florida and Hot 105, then heading into central FL you'd still have a CHR at 105.1 with BJ 105, and you'd hear a station called I-100

Other Florida CHRs from that era: 95.5 WOVV West Palm Beach (debuted in 88), Z-93 Ft. Pierce (debuted in 89), Wail 99 Key West, 107.1 WIIS Key West (Rock friendly), Wink 97 Ft. Myers, 93.7 The Laser Naples, Q-105 Tampa, and of course Power 95 Jacksonville.
I'm also familiar with Knoxville's I-100, which had huge huge ratings in the late 80s/early 90s.
