I put together the list of stations available on the dial in Havana. I used David's two lists from the Cuban government, AM and FM. You can listen to most of them from this webpage:

At one time, 590 CMW in Havana was 150,000 watts. 640 CMQ and 690 CMBC were 50,000 watts. All other Havana stations were 10,000 watts or less, according to Broadcasting Yearbook, which once listed Cuban AM stations.
Today, there is no 590 or 690 in Havana. I suppose they moved to other parts of the island. We assume that several Cuban stations had their power boosted, since they are easy to hear in Florida and other places in the U.S. at night. When I was in South Florida a few years ago, 530 Radio Enciclopedia came in during the day as well as Radio Reloj on 570, 790 and 950. Others Cuban stations were probably audible but if they were just playing music, it would take me a while to figure out if they were Cuban, American or from another country.
