Tactical voice and data communication

DESIGN MTBF's under military airborne conditions are up to 10 times greater than those of present operational equipment. Reliability is enhanced through use of all solid‐state design whenever possible, electronic tuning and switching, a high reliability parts programme and application of multilayer and microelectronic circuits. Modular construction and planar functional packaging are employed. All units meet or exceed MIL‐E‐5400, class IX environmental requirements and are made by the Collins Radio Co.
