We spend one week in June and the entire month of Frebruary in a beachfront condo on the gulf coast right on the AL-FL state line (Two doors down from the famous/infamous Florabana)
Anyway, at that location, the Cuban owns the 530 channel at night. In the daytime, on both the car radio and on the balcony with my Grundig Yacht Boy PE, a faint carrier is discernable but the audio is impossible to make out. I presume its the Cuban, but I'm not sure.
Several other Cubans are clearly audible on a.m. throughout the day at this location. 710 basically throws a dagger right through semi-local WNTM, and all of the major Cuban networks are represented (except for radio Encyclopedia, which probably doens't qualify as a major network in the first place). On shortwave, Radio Rebelde puts in a monster daytime signal on 5025.
