Product and Intended User

The BatteryJack CH-98S-3 is a handle-style speaker microphone designed for ICOM mobile radios including the IC-2100H, IC-2710H and IC-2800H. It connects via an RJ45 8-pin plug and integrates a built-in speaker for receive audio. The unit suits mobile operators who prefer a hand-held mic with local audio rather than relying on the radio's front panel speaker. It is not for users needing a desktop base microphone or a headset-style boom mic.

Audio Performance and Build

High-quality dynamic earphones inside the handle deliver clear receive sound directly to the operator. The heavy-duty push-to-talk button is positioned on the side for reliable keying during extended mobile use. A streamlined shape keeps the microphone comfortable to hold over long operating sessions. No specifications for frequency response, impedance or power handling are provided by the supplier.

Upgrade Context

This microphone replaces a lost or damaged original hand microphone for the listed ICOM models. The jump is worthwhile when the radio's built-in speaker is hard to hear in a noisy vehicle or when the original mic's cable or connector has failed. It does not add features such as DTMF keypad, programmable keys or noise-cancelling elements that are absent from the factory microphone.

Questions about this item

How do I connect the RJ45 8 Pin plug to my ICOM radio?

Align the keyed RJ45 8 Pin connector with the microphone jack on the IC-2100H, IC-2710H, or IC-2800H and push firmly until it clicks; the key prevents upside-down insertion.

Which parts of the CH-98S-3 microphone are most likely to wear out first?

The side-mounted PTT button and the coiled cable flex point near the handle see the most mechanical stress and typically need replacement first.

At what point does the built-in speaker distort during long transmissions?

The dynamic earphone driver remains clear at normal voice levels but can distort if the PTT is held continuously at maximum volume for extended periods.
