I remember in the early 80's, Cuba relayed Radio Moscow on 600 kHz....it was kind of interesting to hear Radio Moscow and their "cold" sound on AM (albeit under a bunch of local US stations).
Also, anyone here remember Radio Free Dixie? (Was that a Cuban effort of some kind?)
I used to listen to ("The World Service of Radio Moscow) on 600am,They could really lay the propaganda on thick(Not as thick as Cuba,Czechoslovakia or Albania). I liked to listen to TransWorld Radio in Bonaire,Netherlands Antilles on 800am also. The voice of Dixie was a Cuban Propaganda vehicle.
