I once visited the WGBS transmitter site. Very impressive, solid block building with a huge generator. The main at the time was an RCA Ampliphase and the aux was an old 10KW transmitter that might have dated back to when they were WFTL and got approval to go from 1400 to 710 with 10KW.
That site is going to become a housing development, and WAQI is moving to the WQBA site at Krome Avenue and the Trail. It will be a serious downgrade in coverage to the north.
