ARRL Clean Signal Initiative

The Clean Signal Initiative (CSI) builds on ARRL’s roles in amateur radio education and technology. Key objectives of the CSI are developing specifications and test procedures that will influence equipment design and manufacturing, and educating amateurs regarding signal purity (avoiding and overcoming poor-quality signals).
CSI brings together ARRL Laboratory staff with member-volunteers, manufacturers, and independent technical advisors with extensive amateur radio design and testing expertise. Together, their work will drive improvements to transmitter and amplifier signal purity, and to help educate amateurs on their use.
