MXF-494 Radio Systems are based on multi-band, multi-function radios designed to provide the military VHF and UHF capability required for ground-to-air and ground-to-ground Line-of-Sight (LOS) communications. They also provide capabilities for civil VHF applications for air traffic control and civil maritime band. The Radio provides both multi-band AM/FM Ground Mobile single-channel communications and UHF ECCM waveforms such as Have Quick I, II, SATURN or National ECCM. Radio operations are selected via a menu driven interactive keypad and display plus discrete controls located on the front of the radio. The radio provides AM single-channel voice and data communications in the UHF frequency band, and FM single-channel voice and data communications in both VHF and UHF bands. The radio also provides clear voice and 16 kbps secure voice operation with external encryption equipment.
