Icom Ui-7 Am Fm Unit [extra Quality] Now
A later generation compact desktop transceiver that requires the UI-7 to expand into FM operation.
Because the UI-7 has been out of production for decades, finding one requires patience and strategy. New-old-stock (NOS) units are incredibly rare, so most buyers will need to source a used unit.
A "fully loaded" IC-725 with the UI-7 and optional narrow CW filters is worth significantly more on the used market than a base unit. Installation and Setup
Once powered back on, the AM and FM mode buttons on the front panel of the radio will now actively route signals through the newly installed UI-7 circuit. Finding a UI-7 Today: Tips for Buyers
How does the UI-7 interact with the IC-706's main controls? Understanding this distinction is critical to using the unit properly. icom ui-7 am fm unit
The 6-meter version of the IC-725 architecture, which relies on the UI-7 for its FM and AM upgrades.
Installing the unit is a satisfying project for ham hobbyists. It requires opening the radio's case and plugging the board into specific internal locations (like connectors J21 and J22). Once installed, it allows the radio to support additional accessories like the , which is necessary for triggering modern repeaters.
On sites like eBay or specialized ham forums (QRZ, eHam), a standalone UI-7 can sometimes sell for upwards of $150–$250.
They crested the ridge just as the enemy closed in. The tanks’ 120mm cannons lit up the valley like noon. A later generation compact desktop transceiver that requires
Amateur radio swap meets (Hamfests) and forums like QRZ or QTH are excellent places to find parted-out radios.
She didn’t tune to the BBC or the Armed Forces Network. She tuned low —to the fringes of the AM band, where the world still whispered.
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 generally considered a user-installable option, though it requires basic comfort with internal radio components: A "fully loaded" IC-725 with the UI-7 and
The 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.
Often shrouded in mystery due to its rarity and unique form factor, the UI-7 is far more than a simple knob. It is a specialized control head—a "micro remote" designed to turn one of the most popular mobile transceivers into an even more flexible base station or stealth mobile setup.
The Icom UI-7 is more than just a simple accessory; it is a testament to the modular design philosophy of a bygone era. For owners of the IC-725, IC-728, and IC-721, this small board is the essential component that transforms their radios from SSB/CW-only rigs into fully capable multimode transceivers. While it can be a challenge to find today, its ability to add AM and FM to these classic workhorses makes it a highly sought-after piece of radio history.
Enter the UI-7. Icom designed this "puck" to be mounted directly on a (via an optional magnetic mount or Velcro) or near the gear shift. It allowed for "eyes-free" operation. You could spin the dial for volume, press the top for squelch, and use the side PTT button to transmit.
Fully enables FM mode, which is essential for working 10-meter repeaters. Triple Conversion Support:
