The 1960s saw fundamental advances in four important areas of communications technology: data transmission through the analog voice channels of the telephone network, computer networking, satellite communications, and lasers and optical fibers. These years also witnessed the initial steps toward the breakup of the Bell telephone monopoly in the US.
A common airborne receiver of that era was the R-65/APN-9 which combined the receiver and cathode ray tube (CRT) indicator into a single relatively lightweight unit replacing the two larger, separate receiver and indicator units which comprised the predecessor APN-4 system.
The stations were connected via line-of-sight horn antennas which transmitted (or received) microwave signals. A call placed in one part of the country would be passed on to the next relay station, then passed on to the next, and so on until it reached the station nearest its destination.
