The Gonset Communicator was a series of vacuum tube VHF AM radio transceivers that were widely sold in the 1950s and early 60s.
[2] The Gonset Communicators were packaged in a square box with a carrying handle and a UHF connector for the antenna on top, making them quite portable.
The Gonset could also be connected to an external speaker and used as a public address (PA) system.
The civil defense model was painted yellow with CD insignia, and was available for the 6 and 2 meter bands.
It added the bank of transmit crystals and included knobs for the transmitter tuning controls, which required a screwdriver in the original.
Contemporary with the Communicators, Gonset also made a full line of amateur equipment.
