Known counterpart stations M08a, SK01

V02a is operated by Cuban Intelligence Directorate (DGI). V02a replaced V02 on 1 January 1997.

V02a always sends three fixed-length messages of 150 groups each. Each transmission is 42 minutes in length. Format:

Preamble Message #1 Message #2 Message #3 Outro
Atención 33312 41082 05572 33312 34188 51181 01831 ... 41082 46909 04343 89535 ... 05572 78905 37216 54849 ... Final

Repeated for 3 minutes Repeated 5 times   Repeated 5 times   Repeated 5 times   Repeated 3 times

In the headers, the first 4 figures comprise the message ID, and the last figure is either 1 or 2.

V02a, along with M08a, was involved in the case of the Cuban Five.

Up until late 2012, when HM01 started operation, V02a operated a large amount of schedules using AM (A3E) mode. However, since then, V02a transmissions are rare. Usually once, sometimes twice a month, on Tuesday and/or Thursday, it replaces M08a, in LSB (J3E) mode.

V02a uses the same transmitters as Radio Havana Cuba, and a computer running Windows XP is used to feed the audio of the transmissions.
