I am a General Class (KK4 area prefix) "occasionally" operating out of Central Florida (when I am back there). I don't have a lot on the DR, but I do know that there is activity. Also, I recall hearing DX from there, but I have nothing in my logs. Having said that, here are some links and potential contacts which may help.
