For daytime AM DXing, the best place is Honeymoon Island in Dunedin because the place is isolated and out on the water.
Last time I was there a couple years ago, it cost $4 to get on the island but it's worth it.
I've noticed a difference between the daytime reception there compared to other places like Clearwater Beach.
As for the Spanish station on 1030, I'm thinking it may be the one from Oveido, Florida.
On Honeymoon Island, you should be able to hear KTRH in the daytime behind WYGM if you have a good receiver.
And when you're in the area, you have to take a ride across the Sunshine Skyway Bridge. It's quite an imperessive drive.
