When I was stationed in the West Indies (VP2EHF), the ¡°uno sero cinco¡± ¡°channel¡± was always in use by the narcotrafficantres. We captured a couple of high-speed boats equipped with Icom marine radios set to 28.105 which we had monitored all the way northwards from South America up to the Anagada Straights. About the time I left for home in 1995 many of the drug runners had installed voice encryption ¡ª both digital and analog scramblers. Those didn¡¯t help them much either.
