Unfortunately, since WTAN's stick is on Clearwater Harbor, the signal goes
out into the Gulf and lands on the coast near Tallahassee, giving fits to a station there on 1330. They really should be on Tampa Bay, probably at the
location of the original WSUN/WFLA 620 directional antenna, which would be
Gulf to Bay and McMullen Booth Road. But I understand that may be problematic with 1330 in Lakeland.
WRMD gets out surprisingly well, and their 590 or so watts on 680 goes farther north during the day than 970, 1040 or 1250. The nighttime power doesn't carry as far as it did when they were on a half-wave stick that was knocked down in the year 2000 by a chopper crash. But it's still audible in much of St. Pete and Tampa after dark.
WRXB's bay advantage is mostly south over Manatee and east into Hillsborough. It actually suffers in north Pinellas because its signal has to go over dry, non-conductive land, and a small part of the county is outside it's 0.5 mv/m
contour.
I would think a closer to the bay location would help stations like 1040 and 1470 cover Tampa at night.
