Y-100 also had an auxiliary transmitter, I believe on the same building, in the late 70's at least. I never visited it, but did get to see the short-guyed tower in the trailer park (where I would doubly not want to be in a hurricane).As I recall, WAXY had an aux site on top of the Landmark Bank building in Ft Lauderdale. I don't know of anyone else in SoFla with an auxiliary site.
