CB and SSB microphone

The Astatic 636LB1 is a dynamic noise-cancelling microphone built for CB amateur radio and single-sideband communications. Its four-pin connector fits compatible transceivers and the handheld form factor suits close-talking operation. Rubberised housing and a polyurethane-coated steel grille protect the capsule in mobile or base-station use. A press-to-talk lever with a DPDT spring-return switch provides reliable keying.

Build integration

The microphone connects directly to any CB or SSB radio that accepts a four-pin dynamic microphone, requiring no external power or preamp. The rugged coating resists vibration and handling noise, freeing the operator from careful placement during vehicle or marine installations. Coiled cable strain relief reduces wear at the connector, keeping the audio path stable over long cable runs.

Sustained use behaviour

The DPDT switch is rated for long life and trouble-free operation through repeated press-to-talk cycles. Dynamic capsule construction maintains consistent output without battery drift during extended transmissions. Rubberised grip and steel grille dissipate heat from prolonged handheld use, while the spring-return lever ensures the circuit opens cleanly when released.
