The UI-7 is generally considered a user-installable option, though it requires basic comfort with internal radio components:
0.5 µV for 12 dB SINAD (typically measured at 28–29.7 MHz). Selectivity: AM: 6 kHz at -6 dB. FM: 12–15 kHz at -6 dB. 📻 Compatible Radios
The board typically plugs into a dedicated socket on the main or PLL unit. Wiring Connections:
The UI-7 is designed to work seamlessly with the radio's front-panel controls.

The "AM/FM Unit" designation is key. Unlike standard VHF microphones that only handle transmission and reception on marine channels, the UI-7 contains a fully functional AM and FM broadcast band receiver. This allows users to listen to commercial radio stations (weather, news, music) directly through the vessel’s speakers or a connected headset, all while maintaining instant priority access to emergency marine VHF channels.
, as these models already have FM and AM transmit capabilities built-in from the factory. 💡 Key Considerations As a discontinued vintage accessory, the
While the UI-7 physically fits inside a select family of late-1980s to mid-1990s Icom rigs, its performance profile varies depending on the specific model layout: 1. Icom IC-725
The installation requires running a single jumper wire from pin J3 on the UI-7 unit to pin J5 on the radio’s front panel board. Because used units often ship without this original manufacturer wire, owners frequently have to fabricate their own bridge using generic terminal wire.
