: for this model, as FM/AM features are built-in. Installation & Use 💡 Quick Tip : Many users look for the to access 10-meter FM repeaters during high solar activity.

The is an optional, internal plug-in circuit board designed to upgrade vintage Icom high-frequency (HF) transceivers by expanding their native operating modes. Produced primarily during the late 1980s and 1990s, this add-on unit allows specific entry-level and mid-range base stations to achieve true "all-mode" capability.

He was a night janitor at the abandoned VHF relay station on the edge of town. The job was simple: sweep, mop, check the backup generators. But the real reason he took it was the silence.

A classic "workhorse" radio where this unit was a popular upgrade.

: The board is designed to control the carrier, typically supporting power levels from 10 watts up to a maximum of 40 watts on certain models like the IC-725.

Interestingly, the physical buttons for AM/FM mode selection are present on the front panel of every IC-725 or IC-728 radio, regardless of the UI-7's installation. The board is what makes those buttons functional for transmitting.

: Requires the UI-7 to use the front-panel AM/FM button; without it, the button has no function. IC-728 : Enables AM and FM modes via this plug-in board. The is an optional, internal plug-in circuit board

Because the UI-7 has been out of production for decades, finding one requires a bit of detective work. Your best bets are:

He drove home in the dark, his ears ringing.
