I'd say its a gray area. It's funded by the United States government, used to be through the United States Information Agency, which in turn was a front for the Central Intelligence Agency. Think Radio Swan and other operations but Radio Marti is closer in affiliation to the VOA, Radio Free Europe, Radio Liberty, Radio Free Asia, etc. Like Radio Free Asia, Radio Marti is heavily jammed by the nation it targets. Radio Marti transmits US-based news and opinion to Cuba, and Cuba therefore jams it.
