The Icom SM-50 is a top-tier desktop dynamic microphone manufactured by Icom Inc. in Japan. Designed for professional base station and coastal radio operations with Icom HF, VHF, and multi-band transceivers, the SM-50 provides high-fidelity, speech-optimized audio for long-range voice communications.

Featuring a high-performance dynamic microphone element housed on a heavy, vibration-damped desktop base, the SM-50 includes integrated Up and Down switches for remote frequency tuning and channel selection directly from the microphone. It features dedicated Push-To-Talk (PTT) and PTT Lock switches alongside a built-in low-cut filter switch on the underside to reduce low-frequency hum, cabin noise, and background rumble during transmissions.
