Radio frequency transmissions flight supports communications on Kadena, worldwide
U.S. Air Force Senior Airmen Nathaniel Lee and William Amarillo, 18th Communications Squadron radio frequency transmissions technicians, measure modulation on a multiband handheld troop radio, commonly known as a brick, on Kadena Air Base, Japan, April 24, 2013. If a radio is out of modulation, the range is significantly reduced and personnel could not talk to other aircraft or personnel during operations. (U.S. Air Force photo by Staff Sgt.
