"Sporadic or non-traditional users of the shortwave bands may include:

Clandestine stations. These are stations that broadcast on behalf of various political movements such as rebel or insurrectionist forces.
They may advocate civil war, insurrection, rebellion against the government-in-charge of the country to which they are directed. Clandestine
broadcasts may emanate from transmitters located in rebel-controlled territory or from outside the country entirely, using another country's
transmission facilities."
