((link)): Icom Ui7 Am Fm Unit
The ICOM UI-7 is an optional internal receiving unit designed to add AM and FM broadcast band reception capabilities to specific ICOM amateur radio transceivers. While ICOM HF transceivers are primarily designed for amateur bands (160m–10m), the UI-7 allows operators to listen to commercial AM radio and FM broadcast stations. This report details the unit's function, compatible hardware, installation, and current availability.
This comprehensive guide covers the technical specifications, compatibility, installation process, and performance expectations of the Icom UI-7 unit. Understanding the Role of the Icom UI-7
Many new owners are confused when they press the AM/FM button on their IC-725 and nothing happens. That's because these modes were optional! You need the installed internally to unlock them. What it does: Adds FM mode (great for 10-meter FM). Adds AM mode for transmit and receive. icom ui7 am fm unit
Incorporates a wideband FM (WFM) discriminator. This allows the receiver to tune into standard commercial FM radio stations (typically 88–108 MHz, depending on the host receiver's frequency range) with proper audio de-emphasis.
: Adds full Frequency Modulation (FM) support, allowing for transmission at up to 100 watts and clear reception. The ICOM UI-7 is an optional internal receiving

is an optional internal module that adds AM and FM transmit/receive capabilities to HF transceivers, most notably the Icom IC-725 Quick Installation Guide Installation requires opening the radio case. Ensure the power is disconnected before proceeding. Access the Interior : Remove the top and bottom covers of the transceiver. Mount the Board
The is a classic, highly sought-after internal option board designed for vintage Icom communications receivers. Specifically engineered for the legendary Icom IC-R71 series—including the IC-R71A, IC-R71E, and IC-R71D—this small circuit board adds high-quality AM and FM reception capabilities to standard shortwave setups. For shortwave listeners (SWLs) and amateur radio operators, finding and installing a UI-7 is the ultimate upgrade to unlock the full potential of these iconic 1980s benchtop receivers.
You can visually verify if the UI-7 is installed on an IC-725 without opening the case. When the UI-7 board is plugged into the main circuit board near the rear of the unit, it occupies space that blocks some of the ventilation grill openings on the bottom of the radio's rear right side.
