The Icom FL-223 9MHz Filter is designed for Narrow Single-Side Band (SSB) filtering with a bandwidth of 1.9kHz. This filter provides a sharp cutoff at -6dB, ensuring precise signal processing for amateur radio operators. Compatible with a range of Icom transceivers, including the IC-775DSP, IC-746, and IC-706, the FL-223 filter enhances reception by reducing interference and improving signal clarity.

With its narrow bandwidth of 1.9kHz, the FL-223 filter is ideal for separating closely spaced signals in crowded band conditions. The sharp -6dB cutoff eliminates unwanted noise and adjacent channel interference, allowing users to focus on the desired signals with enhanced clarity. This filter is valuable to any radio enthusiast’s setup, especially for those engaging in SSB communication where selectivity is crucial.
