Comm makes sure voices are heard
Senior Airman Justin Stone, 375th Communications Squadron radio frequency transmission systems technician, explains how a synthesizer card degrades to Airman 1st Class Devin Scott, 375th CS RF transmission systems technician, as training Feb. 7, 2011 at Scott Air Force Base, Ill. The synthesizer card was removed from a RT-1319B UHF/VHF radio unit and is used to create a frequency that enables the radio to transmit a signal. (U.S. Air Force photo/Staff Sgt. Brian J. Valencia)
