Icom Ui-7 Am Fm Unit [extra Quality] Jun 2026

Amateur radio swap meets (Hamfests) and forums like QRZ or QTH are excellent places to find parted-out radios.

Replace the top cover of the radio and secure it with the original chassis screws. Reconnect your power supply and antenna. Power on the rig and cycle through the mode button. You should now be able to select without the radio muting. Tune to a known local FM signal or repeater to test the audio and squelch controls. Troubleshooting & Tips for Buyers

While the IC-725/728 natively handles USB/LSB and CW, the addition of the UI-7 brings FM capability. This is crucial for operating 10-meter FM repeaters ( ), allowing local, high-quality, noise-free communication. 2. Enhanced AM Capability

When integrated into a compatible transceiver like the IC-725, the Icom UI-7 changes the operational power footprint and performance profiles of the host radio: Performance Specification AM (Transmit/Receive), FM (Transmit/Receive) Host Transceiver Compatibility IC-721, IC-723, IC-725, IC-726, IC-728, IC-729 AM RF Output Power Continuously adjustable from 10W up to 40 Watts FM RF Output Power Continuously adjustable from 10W up to 100 Watts FM Receiver Architecture

, as those models already include AM/FM functionality as standard. Internal Connections icom ui-7 am fm unit

If you are looking at a used IC-725 or similar vintage radio, there is a simple way to check for the presence of a UI-7 without opening the case. Because the board is installed on the bottom of the main circuit board, it physically blocks some of the cooling vents on the radio's underside. inside.

Out of the box, the legendary Icom IC-725 limits operators to SSB (LSB/USB) and CW modes at 100 watts. Adding the UI-7 completely reconfigures the transmitter output profile:

After installation, the radio might require minor adjustments to the squelch or FM detection levels, as outlined in the radio’s Service Manual . Note: For the

Installing the unit is a satisfying project for ham hobbyists. It requires opening the radio's case and plugging the board into specific internal locations (like connectors J21 and J22). Once installed, it allows the radio to support additional accessories like the , which is necessary for triggering modern repeaters. Amateur radio swap meets (Hamfests) and forums like

Here are some technical specifications of the Icom UI-7 AM/FM unit:

The UI-7 is a fully functional DSC controller. It features a dedicated under a protective cover, along with individual buttons for position request, position send, and individual calls. The large, backlit LCD screen displays GPS position data, MMSI numbers, and DSC call status.

At its core, the is a dedicated remote control microphone and audio distribution unit . However, calling it simply a "microphone" would be a gross understatement. The UI-7 is a sophisticated combination of a Class-D DSC (Digital Selective Calling) handset, a secondary station controller, and an integrated AM/FM radio receiver.

: It is a small add-on board that plugs directly into the bottom of the radio's chassis, often requiring only a few internal cable connections to the existing front panel and main logic units. Applicable Radios Power on the rig and cycle through the mode button

The board is a plug-in unit typically installed in the bottom section of the radio.

$300 – $450 USD (depending on cable and mounting kit inclusions). Note: This does not include the main IC-M605 or IC-M400BB transceiver, which typically retails for $500–$800.

Word of the UI-7’s forecast spread. People began to bring their radios to Maya, not because she could fix everything — she couldn’t — but because the machine made people feel seen, as if the harbor itself had been given a voice. An old captain left a thermos and a story about beating a storm off Cape Verde; a teenage apprentice from the shipyard asked how a capacitor could look tired and what that said about other things, like people.

When installed, the UI-7 board enables your Icom radio to in AM mode and to both transmit and receive in FM mode.

The Icom UI-7 is a vintage AM/FM receiver unit designed as an internal expansion module for classic Icom communication receivers, most notably the legendary Icom IC-R71A, IC-R71E, and IC-751 transceiver series. During the golden age of shortwave listening in the 1980s and 1990s, this specialized option allowed operators to expand the frequency capabilities of their base stations to include high-fidelity AM and wideband FM broadcast audio.
