Tactical Hands-Free Communication with Sub-PTT Control
The Icom HM238MC is a specialized tie-clip microphone designed for professionals who require discreet yet highly functional communication control. This rugged microphone is equipped with a unique Dual PTT (Push-to-Talk) system, featuring a main button and a secondary "Sub PTT" button. This configuration is specifically engineered for multi-channel or dual-band operations, allowing users to switch between communication groups instantly without adjusting their radio. With a 1000 mm (39.4 in) cable length, it provides ample slack for routing through uniforms or tactical vests.
Built for reliability in active environments, the HM238MC features a 14-pin spring-type connector that ensures a secure, vibration-resistant link to your portable radio. It includes an integrated 2.5mm earpiece jack, allowing users to add a listen-only earpiece for private reception in noise-sensitive or high-decibel settings. Rated at IP54 for dust and water resistance (excluding the earpiece jack), this tie-clip microphone is a durable solution for security teams, dispatchers, and industrial personnel using Icom’s latest IP and digital hybrid platforms.

Frequently Asked Questions
What is the purpose of the Sub PTT button? The Sub PTT allows you to transmit on a secondary channel or talkgroup (such as an LTE talkgroup on the IP730D) without having to toggle switches on the radio itself.
Is the entire unit waterproof? The microphone body is rated IP54, which protects against dust and water splashes. However, the 2.5mm earphone jack is not waterproof, so care should be taken in heavy rain.
Can I use any earpiece with this? You can use any standard listen-only earpiece that features a 2.5mm (2.5φ) single-pin plug.
