In May 2021, new FCC rules regarding exposure to RF energy went into effect. The limits haven’t changed, but the ways that some amateur operators can determine whether their stations are exempt from evaluations are different. ARRL Lab Manager Ed Hare, W1RFI, explained the rules, how to evaluate your station, and how to conduct your own evaluation using ARRL’s RF Exposure Calculator (www.arrl.org/rf-exposure-calculator). Ed has worked at ARRL Headquarters since 1986.
He started as the test engineer for “Product Review” in QST, then became ARRL’s “RFI guru” (notice his call sign), and now works as ARRL Laboratory Manager. His RFI articles have been published in QST and other ARRL publications, including The ARRL Handbook for Radio Communications, and have appeared in professional trade journals. He represents amateur radio with various industry groups including IEEE and ANSI standards committees.
