Motorola Solutions NNTN8235A Military RSM for SRX2200 - Rugged Comm

Our review of the Motorola Solutions NNTN8235A Remote Speaker Microphone summarizes why it stands out for field operators who need reliable, weatherproof voice comms. Built specifically for the SRX2200 combat radio, this coyote brown RSM combines an IP57 submersible rating with windporting technology to keep transmissions clear in heavy wind and storms. The unit's intrinsically-safe rating and military-focused design make it a focused choice for tactical teams, search and rescue, and any user who must maintain hands-free, durable communications in harsh environments.

Key Features

• Military tactical design: Purpose-built for SRX2200 radios to provide a secure, form-fit remote speaker microphone for combat-style use.
• Windporting technology: Reduces background noise from high winds and severe weather so voice audio remains intelligible at range.
• IP57 submersible rating: Protects the microphone against dust ingress and temporary submersion for dependable field use in wet conditions.
• Intrinsically-safe rating: Allows operation in hazardous atmospheres where spark risk is a concern, expanding permitted deployment scenarios.
• Coyote brown finish: Blends with tactical gear and uniform colors for low-visibility carry in military or law enforcement roles.

Who It's For

This Remote Speaker Microphone is aimed at military units, law enforcement, and tactical teams using SRX2200 combat radios who require a robust, weatherproof accessory. It is best when deployed by personnel operating in windy, wet, or potentially hazardous environments where reliable, clear voice transmission is essential.

Not every radio user needs the specialized build and ratings of this RSM; civilian hobbyists or office-based two-way radio users who do not face severe weather or ATEX-like environments should consider more general-purpose microphones with lower-cost options.

Pros & Cons

Pros

• Durable, tactical construction matched to the SRX2200 form factor for secure attachment and use in the field.
• Windporting noticeably reduces wind noise, improving voice clarity during outdoor operations.
• High ingress protection (IP57) offers confidence when operating in rain, mud, or temporary submersion.
• Intrinsically-safe certification enables use in atmospheres with flammable gases or dust where ordinary devices would be restricted.

Cons

• Specialized military fit means it is intended for SRX2200 models and is not a universal RSM for all radios.
• Coyote brown finish is tactical, which may not suit non-uniform applications or civilian aesthetics.
