Transmission Facilities

Radio Marti: Marathon Key, Florida -- Facilities include a directional 
four-tower antenna array and two 50 kilowatt (kW) transmitters operating on 
1180 kHz (medium wave) as well as a power combiner system that allows the 
station to transmit a more powerful 100 kW signal during daylight hours. The 
broadcast signal is sent by satellite from Miami to Marathon Key. Radio 
Marti also broadcasts on a total of four separate shortwave frequencies each 
hour from Greenville, North Carolina, and Delano, California.

TV Marti: TV Marti's antenna and transmitter are mounted aboard an aerostat 
balloon tethered 10,000 feet above Cudjoe Key, Florida, and transmit one of 
three available UHF-TV channels. Programming originates in studios in Miami 
and is transmitted to the Florida Keys by satellite. The signal is then 
relayed to a transmitter and a highly directional antenna mounted aboard an 
aerostat for broadcast to Cuba. The TV Marti system has safeguards that 
prevent interference with existing domestic and foreign TV stations.
