One of the earliest major post-World War II examples of clandestine broadcasting occurred in connection with Fidel Castro's seizure of power in Cuba.

• Part I- Revolutionary (pro-Castro) Radio Activities - Here is Part I of a two-part work, Clandestine Radio Operations in the Cuban Revolutionary and Counter-Revolutionary Movement: 1953-1965, written by Don Jensen in 1965. In Revolutionary (pro-Castro) Radio Activities, Don covers the period from Castro's attempt to seize the station at the Moncada Barracks in 1953 to the inauguration of "La Onda Corta Experimental Cubana," later Radio Havana Cuba, in 1961. Thanks to Don for permission to post these items, which are early examples of good station-related research emanating from within the DX community.
• Part II-Counter-Revolutionary (anti-Castro) Radio Activities - Part II treats Castro's radio opponents, from the anti-Communist programs of CMKC in 1959, through the American broadcast band programs, the VOA mobile stations, the WRUL broadcasts, numbers stations, etc.
