: This unit is highly sought after by operators who want to use FM on the 10-meter band (29.6 MHz), which is popular during high sunspot cycles. Power Adjustment
Similar to the 725 but featuring built-in 6-meter (VHF) capabilities. It utilizes the same internal expansion architecture as the 725. For an hour, the little Icom unit held
The provides a robust, integrated broadcast radio solution for professional Icom radio platforms. It eliminates the need for a separate consumer radio, offers automatic mute during critical communications, and maintains a clean installation. Ideal for marine and mobile applications where space, power, and audio routing are already managed by an Icom transceiver.
Enables USB, LSB, CW, AM, and FM, unlocking full multi-mode capabilities. Receiver Performance FM Sensitivity: Provides a sensitivity of less than (12 dB SINAD). AM Sensitivity: Provides a sensitivity of less than (10 dB S/N). Power Adjustment Similar to the 725 but featuring
: Icom IC-729 . While closely related to the IC-728 family, the IC-729 was shipped with factory-integrated AM/FM capabilities to accommodate its stock 50 MHz (6-meter) band features. Installation and Troubleshooting Tips
The Icom UI-7 AM/FM Unit is a classic, highly sought-after internal expansion module designed for vintage Icom communication receivers and transceivers. Produced during the golden era of amateur radio engineering, this optional board adds standard broadcast band reception capabilities to premium base stations that lacked integrated AM/FM circuitry out of the box. Today, it remains a prized component for ham radio collectors, shortwave listeners (SWLs), and restoration enthusiasts looking to maximize the utility of their vintage Icom gear.
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.
