This Cuban station typically starts broadcasting at the zero minute mark with a YL announcing "Atencion" several times. During the message section, Spanish numbers (cero uno dos tres cuatro cinco seis siete ocho nueve) are arranged in groups of five digits. The end of the broadcast consists of the word "final" repeated.
V2 is often heard in North America at night, on frequencies such as 5800, 5883, and 5898 kHz. Broadcasts typically last 30-40 minutes.

V02a, along with M08a, was involved in the case of the Cuban Five "Atencion" Spy Case.
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.
