From repair and parts lists:
The is a classic, highly sought-after internal expansion module designed for vintage Icom communications receivers . Produced during the golden era of amateur radio engineering, this optional board adds high-quality AM and FM reception capabilities to compatible base stations and receivers.
If the unit includes a screw, secure the board to the standoff to ensure it doesn't move. Reassemble: Replace the top and bottom covers.
: Secure the wiring with ties and replace the covers. How to Identify if a UI-7 is Installed icom ui7 am fm unit
This "piggyback" design made the UI-7 and UT-30 an incredibly powerful and space-efficient upgrade package.
The UI-7 unit is a plug-in circuit board that broadens the operational versatility of compatible HF transceivers.
The IC-R6 is a perfect example of Icom's engineering prowess: a miniaturized, efficient radio that fits in a pocket without sacrificing essential features. From repair and parts lists: The is a
Integrates directly with the receiver's 9.0115 MHz and 455 kHz Intermediate Frequency (IF) stages.
For amateur radio hobbyists, installing the UI-7 is highly accessible and requires minimal technical expertise.
The Icom UI-7 is not a universally compatible accessory. It was designed for a specific family of Icom HF radios. The primary compatibility list includes the . However, a notable exception is the Icom IC-729 , which came from the factory with these modes already built-in, rendering the UI-7 unnecessary. Reassemble: Replace the top and bottom covers

The Icom UI-7 is an analog multi-mode detection module. While the IC-R71 series comes natively equipped with SSB (Single Sideband), CW (Continuous Wave), RTTY, and standard AM modes, the stock AM filter and detection can sometimes feel restrictive. The UI-7 optimizes AM envelope detection and introduces a dedicated narrow/wide FM discriminator circuit.
Compact, multi-pin plug-in printed circuit board (PCB) requiring no external wiring or soldering for standard installation. Compatibility: Which Radios Accept the UI-7?
