The UI-7 module integrates directly onto the main circuit board architecture of the radio. While this guide focuses on the popular IC-725 layout, the general philosophy applies to other compatible Icom models. Step 1: Remove the Case Covers
Remove the screws securing the bottom cover (typically 5 or 6 screws depending on the exact model variant). Gently lift the bottom cover off and set it aside.
Press the mode keys on the front panel. You should now be able to cycle into the "AM" and "FM" modes seamlessly. icom ui7 am fm unit install
The is an optional internal expansion board that adds AM transmission and FM transmit/receive capabilities to select Icom transceivers, most notably the IC-725 , IC-728 , and IC-729 . Without this unit installed, these radios are typically limited to SSB and CW modes for transmission. Installation Procedure
Turn on the Icom UI-7 unit and test its functions, including: The UI-7 module integrates directly onto the main
Some users report that while the board adds functionality, the sound quality in AM mode can be limited by the radio's "barn door wide" filtering, which may lead to noise issues on crowded bands.
The UI-7 contains CMOS components that are highly sensitive to static electricity. Wear your grounding strap throughout the process. Step-by-Step Installation Guide Gently lift the bottom cover off and set it aside
The Icom UI-7 is a popular amateur radio transceiver that offers a wide range of features and capabilities. One of the most useful upgrades you can make to the UI-7 is installing an AM/FM unit, which allows you to transmit and receive on the AM and FM bands. In this post, we'll walk you through the process of installing an AM/FM unit in your Icom UI-7, including the necessary tools, components, and steps.
Installing the Icom UI-7 is a rewarding project that breathes new life into classic HF rigs like the IC-725 and IC-728. By carefully following these step-by-step instructions, you can successfully add AM and FM transmit and receive capabilities to your transceiver, expanding its utility for everything from working AM mode on 29 MHz FM to having simple, local-communication options on the 10m and 6m bands. While this project is well within the reach of a careful hobbyist, always prioritize safety and, when in doubt, consult a professional. Take your time, secure your connections, and enjoy the new versatility of your upgraded Icom radio.
