Here are the ones I remember, but I believe they are all on standard channels, have switched to FM, or no longer exist:
605 I am unsure whether Radio Moscow in Cuba was ever here, or only on 600 and 1040.
705 Cayman Brac, Cayman Islands (moved to FM)
834 Belize City, Belize (technically Central America, moved to 830, then to FM)
1035 4VEC/4VEF/4VEH, Cap-Haïtien, Haiti (moved to FM, not listed with call letters)
1555 Grand Cayman, Cayman Islands (might be on 1205)
1610 Carribean Lighthouse, Antigua (now a standard channel, but moved to 1160)
