You've got WPMZ East Providence, "Poder 1110." It's 5,000 watts, daytime only and kinda directional from a 2-tower array in East Providence. It's Spanish Tropical, pretty good stuff if you're into it! poder1110.com
WKKB Middletown-Providence, 100.3 FM. It's a class A from the old TV6 tower in Tiverton, pretty good coverage. It's your typical Spanish, I still hear some salsa from time to time.
WRNI 1290am is Latino Public Radio, 10,000 watts full time directional from Providence. It's non-commercial listener-supported.
There's also WIGV-LP, a little LPFM on 96.5 with a Spanish Religious format.
