1470 has replaced the entire ground system within the last few years or so. I recall flying over the site and from the air, you could see fresh plow marks in the dirt radiating out from the tower. Probably the biggest problem there is the sugar sand is not very conductive and the higher frequency is also a drawback to ground wave signal. RE the DX. It has been great this winter. This is a sunspot minimum and the skywave is great. 530 from the Turks and Caicos islands is booming in here in Sarasota. Here's a tip if you want to know whether the skywave is really good. Tune to 1520 after sunset and if you hear a 1 khz hetrodyne tone, that is 1521 in Saudi Arabia. Usually a good harbinger of whether the DX will be good.
