There's a thread a little back on this board about it.
Speculation includes, due to the fact that KOOL is doing well, ZZR is not, and CC would be foolish to trash the inroads they've made, WOLL moving back to 94.3 (now a 50kw C2), and WZZR going to 105.5 when it goes (back) to Stuart/Port. St. Lucie. What makes this interesting is that WQOL in Vero Beach just reimaged (again) as Oldies 103.7 targeting the Treasure Coast, and ZZR's simulcast on 101.7 in Vero, WCZR, is in the Aloha Trust.
I'm also wondering about the viability of an on-channel booster for WQOL in St. Lucie County, near PSL or St. Lucie West.
Dr. Tillery or David Eduardo could provide more professional insight. Gentlemen??
