The Sonar Radio Corporation of Brooklyn, NY had its roots in post-war NBFM gear. In later years, its product line expanded with mobile and fixed station HF and VHF gear as well as several sideband transceivers. The FM-3602 was a 25 watt, 8-channel FM transceiver for the 2-meter band. Pushbuttons selected crystal pairs. It came with a quick removal mobile mount and microphone.
