Icom Ui7 Am Fm Unit (QUICK — 2027)

By installing the UI-7, operators turn their specialized communication rigs into versatile, all-in-one receivers capable of picking up standard AM radio stations, commercial FM broadcasts, and wideband FM public safety signals. Key Features and Specifications

Without the UI-7, an IC-725 is essentially "blind" to FM repeaters. Installing the unit unlocks a whole new segment of the 10-meter band.

: Secure the expansion unit using the built-in bolt-on ground standoffs. Be exceptionally gentle with the miniature coax jumper lines; pinched cables during top-cover reassembly can severely attenuate the FM RX sensitivity or disrupt carrier power regulation.

Note: Always verify with your specific radio's service manual, as some, like the IC-725, may require additional filters or boards (like the UT-20 tone encoder) to fully utilize FM repeater functionality. Performance Capabilities with the UI-7 Installed icom ui7 am fm unit

The Icom UI-7 unit was engineered during a period when Icom designed highly modular radio architectures. It targets a distinct family of popular HF rigs:

$180 to $250 USD (Main unit only; does not include antenna or speakers).

Fully integrated with the radio’s main VFO (Variable Frequency Oscillator) tuning dial, memory channels, and front-panel mode selectors. Step-by-Step Installation Guide By installing the UI-7, operators turn their specialized

During the golden age of shortwave radio in the 1980s and 1990s, manufacturers frequently sold base-model receivers with modular expansion slots. This kept initial consumer costs down while allowing operators to customize their rigs. The Icom UI-7 was born out of this philosophy.

button will become functional. Without this board, pressing the button usually does nothing.

Some operators have successfully adapted or utilized similar UI-series boards in these transceiver counterparts, though the layout is optimized specifically for the R71 receiver line. : Secure the expansion unit using the built-in

Integrates directly with the receiver's 9.0115 MHz and 455 kHz Intermediate Frequency (IF) stages.

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?

The radio will transmit approximately 40 watts on AM.
