I was going to mention Radio Taino as an FM-only network. Back in the day...the late 80's, during the 'radio war' between The US's Radio Marti and high powered AM Cuban stations, Taino was on 1180 and branded itself as "La Turemisora de Cuba" (Cuba's Tourist Station) with a music intense format, mixed with tourist information in Spanish. I do remember a "Legal ID' in Spanish and English. This would have been around 1988ish.
I also hear Radio Enciclopedia on 530 AM most nights with Easy Listening (mostly instrumental) music.
