Application & Installation
This control knob is designed for use on various controls across multiple Icom HF transceiver models, potentially serving functions such as AF gain, RF gain, or other front-panel adjustments depending on the specific radio model and control position. The knob is a user-replaceable component requiring no special tools. To remove the old knob, pull firmly straight off the control shaft. For installation, align the unique D-shaped opening with rectangular cutout and the circular positioning features on the bottom of the knob with the corresponding shaft profile and alignment pins on the radio, then press firmly until the knob seats completely against the radio's front panel. The complex shaft coupling design visible in the bottom view ensures the knob can only be installed in the correct orientation and prevents any slippage during operation. The deep vertical ribbing provides excellent tactile grip for precise control adjustments - particularly important for HF transceivers where fine tuning and careful gain adjustments are critical for optimal performance. Replacement is needed when the original knob becomes worn, cracked, damaged, or is lost. This is a simple repair that any radio owner can perform without tools or technical expertise.
