The Yaesu SSM-85D is a genuine, high-fidelity multifunction hand microphone equipped with a full DTMF keypad and programmable function keys, designed specifically for the latest generation of Yaesu C4FM digital and analog mobile transceivers. It allows direct frequency entry, repeater control, real-time DTMF tone transmission, and seamless navigation through the transceiver’s primary functions without having to reach for the front panel while driving or operating from a base station.
Built with highly wear-resistant materials and an ergonomic, secure-grip design, it features a tactile PTT switch with a solid feel and a heavy-duty flexible coiled cord terminated in an 8-pin RJ-45 modular plug. It includes four assignable function keys (P1, P2, P3, and P4) that allow operators to store personalized shortcuts for menus, bands, power levels, or VFO/Memory switching, ensuring quick, intuitive, and safe operation on the road.
Key Advantages
- Full DTMF Numerical Keypad: Direct operating frequency input and instant DTMF tone generation for access to gateways, autopatches, or repeaters.
- Four Programmable Keys (P1–P4): Customizable shortcuts configurable directly from the transceiver menu to activate primary functions with a single press.
- Optimized Modulation Capsule: Clean, well-balanced voice pick-up engineered specifically for articulate C4FM digital and analog FM transmissions.
- Vehicle Ergonomics and Durability: Rugged housing with a positive-click lateral PTT button and a rear button hanger for dashboard microphone brackets.
- Heavy-Duty Coiled Cable with RJ-45 Plug: Reinforced elastic cord with an 8-pin modular connector designed to prevent accidental pull-outs and disconnections.
Recommended Applications
Mobile Vehicle and Fleet Installations
Simplifies frequency entry and memory channel switching straight from your hand, enhancing safety and driving convenience behind the wheel.
System Fusion (C4FM) Digital Networks and Analog Operation
Essential for interacting with nodes, WiRES-X digital rooms, and repeaters that require command sequences or DTMF codes for opening and control.
Amateur Radio Base Stations
Enables agile desk operation in the radio shack, replacing or complementing desktop microphones on FTM-series rigs.

Frequently Asked Questions
Can the P1 to P4 function keys be reassigned?
Yes, the four programmable keys are configured directly via the setup menu of the compatible Yaesu mobile transceiver, allowing you to assign functions such as band selection, transmit power adjustment, scan activation, or squelch control.
Can I dial frequencies manually without touching the transceiver front panel?
Yes, using the full DTMF numerical keypad, you can directly input operating frequency digits into the VFO to immediately jump to the desired frequency or channel.
Is it compatible with legacy Yaesu transceivers?
The SSM-85D is designed and optimized for the command protocol used in current models (such as the FTM-500D, FTM-300D, FTM-6000E, and FTM-510 series). On older Yaesu rigs with an RJ-45 jack (such as the FT-7900 or FT-8800), basic mic audio and PTT will function, but programmable key assignments and DTMF command signaling may exhibit behavioral differences.
