Genuine Icom Low Band RF Board for IC-F4161 Series Digital Radios
This is a genuine Icom RF board assembly designed for the IC-F4161DS and IC-F4161DT digital two-way radios. This is the low band RF board variant, which handles radio frequency transmission and reception functions for the lower portion of the UHF frequency range. The green PCB features multiple shielded RF sections with metal cans, surface-mount components including inductors, capacitors, resistors, an integrated circuit (visible marking "NX52"), and multiple connector interfaces for integration with the radio's main board. The board includes mounting holes with copper reinforcement rings and features precision RF circuit design essential for proper transmit and receive performance.

Application & Installation
This RF board is a critical and complex component that requires professional installation by a qualified Icom technician or authorized service center. The RF board is responsible for all radio frequency functions including signal generation, amplification, filtering, modulation, and demodulation. Replacement is necessary when the radio experiences transmit or receive failures, reduced power output, poor sensitivity, inability to access certain frequency ranges, or other RF-related malfunctions. Installation involves complete radio disassembly, disconnection of multiple cable harnesses and connectors, removal of the failed board, installation of the new board, and reconnection of all interfaces. After installation, the radio requires comprehensive alignment and testing using specialized RF test equipment including power meters, spectrum analyzers, frequency counters, and deviation meters to ensure it meets FCC specifications for power output, frequency accuracy, modulation, and spurious emissions. This is not a user-serviceable repair and should only be performed by technicians with proper training, tools, and Icom service documentation. Improper installation or lack of post-installation alignment can result in radios that operate out of specification, violate FCC regulations, or fail to communicate properly with other radios in the system.
