Gonset was an all American radio manufacturer. The company was founded by father Gonset, but only really took off when his son, Faust Gonset joined him in the 1940s.
The most famous and prevalent Gonset radios were the Communicator series of AM transceivers for 6 and 2 meters. Back in the days most VHF communication was done in AM and Gonset sold large quantities of these rigs.
Gonset didn't survive the transition to solid state. Faust Gonset sold the company to one of his suppliers, then it was sold one more time in the 1960s before vanishing without a trace.
