The Yaesu MH-59A8J is a genuine, high-end multifunction hand microphone equipped with a full DTMF keypad and advanced remote control functions, specifically developed for the Yaesu FT-857D and FT-897D multiband transceivers. Designed to put full radio operation into the palm of your hand, it eliminates the need to navigate menus or adjust front panel dials while driving or working in the radio shack.
In mobile setups where the FT-857D is mounted under the dashboard or in lower consoles, this microphone transforms the operating experience: it enables direct numerical frequency entry, quick access to primary radio parameters, and instant DTMF tone transmission for accessing repeaters and gateways. Its high-fidelity voice capsule ensures crisp, clear modulation across HF, VHF, and UHF bands alike.
Key Advantages
- Full DTMF Keypad: Direct numerical entry of operating frequencies without needing to rotate dials or scroll through nested menus.
- Comprehensive Remote Radio Control: Allows managing modes, bands, and primary features directly via the microphone buttons.
- Custom-Built for FT-857D and FT-897D: Seamless electronic integration and command protocol guaranteed by Yaesu.
- Safety and Comfort for Mobile Operations: Simplifies radio operation on the road without taking your eyes off the route.
- Repeater Tone Generation: Over-the-air DTMF sequence transmission to interface with link systems, internet gateways, and analog repeaters.

Frequently Asked Questions
Can I use this microphone on other Yaesu transceivers that have an RJ-45 socket?
Although the 8-pin modular plug fits mechanically into other Yaesu models (such as the FT-817, FT-818, or FTM mobile series), the internal data lines and remote control protocol of the MH-59A8J are designed and configured exclusively for the architecture of the FT-857D and FT-897D transceivers.
What is the difference between this model and the standard MH-31A8J microphone?
The MH-31A8J is a basic hand microphone with a tone switch and UP/DWN buttons, whereas the MH-59A8J adds a complete numerical DTMF keypad and dedicated control buttons that allow full remote command of the transceiver’s menus and operational features.
