That classical station sounds like, though without an ID I can't say entirely for sure, Radio Enciclopedia from Cuba. The other one doesn't seem like Rebelde from the same country, given your description of the content, but maybe? I'd suggest matching a 530 signal to 5025 on SW, but Rebelde doesn't sign on until later on shortwave. Pretty sure someone here said they took storm damage.
Could there be a Radio Progreso outlet on 530? Or maybe you had somebody from XE-land (Mexico). All I can say for sure is, none of those was Jil FM from Algeria! XD that's 531 anyway. some day... sigh.
