Icom Ui-7 Am Fm Unit
The UI-7 is not a standalone device. It requires a compatible Icom main transceiver. The primary pairings are:
Note: The UI-7 typically connects to the main transceiver via a standard 8-pin modular connector, but for full AM/FM audio and advanced control, specific wiring and bus connections are required.
Critical for safety, the UI-7 allows you to monitor:
For amateur radio operators, the UI-7 represents a classic aspect of the hobby: modification and expansion. In the era when the IC-207H was a primary mobile rig for many hams, having a single device that could serve as a 2m/70cm transceiver and a stereo FM radio receiver was a significant space-saver in a vehicle dashboard. icom ui-7 am fm unit
The genius of the UI-7 lies in its simplicity. Instead of reaching for the main radio faceplate—which might be hidden under a dashboard, inside a go-box, or mounted in a remote location—you can mount this small, magnetic-backed puck on your steering wheel, dashboard, desk edge, or even on your leg using a strap.
The Icom UI-7 is not a standalone radio. It is an optional internal unit designed specifically for the Icom IC-705 (and potentially its predecessors like the IC-706 series, though primarily for IC-705). Its sole purpose is to add broadcast band AM and FM reception (typically 0.5–1.7 MHz AM and 76–108 MHz FM) to the IC-705, which otherwise is an HF/50/144/430 MHz all-mode transceiver but does not include wide-band broadcast FM as a standard feature.
Important: Some confusion exists because Icom’s naming convention overlaps. The UI-7 is not a standalone receiver or a car stereo. For the IC-705, it’s an internal module that plugs onto the main board. The UI-7 is not a standalone device
If your main transceiver is in a flooded or inaccessible engine room, the UI-7 provides a surprising level of stand-alone functionality. The handset itself has enough local intelligence to act as a secondary control point. While the radio brain is offline, you can still use the UI-7 as a listen-only device.
The Icom UI-7 AM/FM Unit is more than a remote microphone; it is a testament to Icom’s philosophy of "professional-grade" marine electronics. It eliminates the need for a separate marine stereo, provides a redundant command point, and integrates safety (DSC) with entertainment (AM/FM) in a waterproof, night-usable package.
If you are rigging a center console for offshore fishing, a trawler for long-loop cruising, or a commercial vessel needing absolute reliability, pairing an Icom IC-M605 with a UI-7 is arguably the best investment you can make. You get the ruggedness of a commercial radio with the comfort of a car stereo. Note: The UI-7 typically connects to the main
The UI-7 doesn’t just send and receive; it becomes the audio hub of your vessel. And in a storm, with rain lashing the windscreen, you’ll be grateful that one handset lets you monitor Channel 16, call the marina, and get a local weather forecast on AM—all while keeping your other hand on the wheel.

Given that you specified "AM FM unit," I am proceeding with a review of the Icom UT-106 AM/FM Controller Unit, which is the internal module that adds broadcast radio reception to marine handhelds.
