A radio frequency transceiver system is used for communications among the crewmembers of an aircraft, either inside or immediately outside. Aside from employing analog and digital circuits, the system utilizes Frequency Hopping Spread Spectrum (FHSS), Digital Spread Spectrum (DSDS), Time Division Duplex (TDD) or Time Division Multiple Access (TDMA) as to provide reliable and secure communications contact, regardless of adverse weather conditions, handling or operating stresses, or other conditions which would otherwise affect transmissions as in prior art devices. The system virtually eliminates interconnect aircraft cable damage; operational delays caused by missing cables, or broken cables; and delays or malfunctions resulting from having cables of the wrong size, length, weather resistance, etc. Since a crewmember has no interconnecting aircraft cable, this system allows greater freedom of moment about the aircraft, and crewmembers can no be inadvertently tripped, or lose balance.
