U20554 Used ICOM SM-20 Desktop Microphone

U20554 Used ICOM SM-20 Desktop Microphone

This pre-owned Icom SM-20 desktop microphone is in great overall condition, showing only minor cosmetic handling marks on the molded base assembly from routine shack use. The front-panel PTT bar, Lock button, and Up/Down frequency stepping buttons actuate crisply with clean, clear labeling. The flexible metal gooseneck holds position firmly, and the microphone element head and windscreen are clean and undamaged. On the weighted bottom plate, the rubber non-skid feet, microphone gain trimmer, and low-cut filter slide switch are in great shape. The captive coiled/straight cord terminates in an 8-pin round metal foster connector with bright plating and clean pins. It comes complete in its original Icom factory retail box.

The Icom SM-20 is a high-performance electret condenser desktop microphone engineered specifically for Icom HF and all-mode base station transceivers. Designed to deliver broadcast-quality transmit audio, it features a unidirectional electret condenser element tailored to enhance speech articulation and punch across SSB, AM, and FM modes. The heavy die-cast weighted base provides rock-solid desk stability during operating sessions, while the integrated flexible gooseneck allows precise positioning for maximum operator comfort. The underside features an adjustable microphone gain potentiometer along with a selectable low-cut filter switch designed to attenuate low-frequency room rumble and background noise. With convenient front-mounted Up and Down frequency scan buttons, a broad PTT bar, and a dedicated Lock button, the SM-20 is a classic, ergonomic audio upgrade for modern and legacy Icom shacks alike.
