WOKV-AM in Jax is a class B, 50kW day/25kW-DA night. WOKV-FM is a full class C at almost 100kW. The AM has a much larger coverage area than the FM during the day, but much smaller at night.
WDBO in Mousetown is a class B, 5kw day and 5kw-DA night. WDBO-FM is also a full class C at almost 100kW. Daytime coverage is comparable for both signals, but the FM will have much more coverage at night.
Compare to WSB-AM, a class A clear channel station 50kW day and night. WSBB-FM with the new signal will be a class C1 with a slight null to the NW, and 100kW. WSB will still have more coverage than WSBB-FM, even with the new signal, 24/7.
The two Florida AMs suffer in night coverage, as one would expect. Daytime they are at least comparable.
Do the Florida AMs do any PXP of local teams? I would think that weak night coverage would hurt that.
