ARLB011 Updated Radio Frequency Exposure Rules Become Effective on
The FCC has announced that rule changes detailed in a lengthy 2019
Report and Order governing RF exposure standards go into effect on
May 3, 2021. The new rules do not change existing RF exposure (RFE)
limits but do require that stations in all services, including
amateur radio, be evaluated against existing limits, unless they are
exempted. For stations already in place, that evaluation must be
completed by May 3, 2023. After May 3 of this year, any new station,
or any existing station modified in a way that’s likely to change
its RFE profile – such as different antenna or placement or greater
power – will need to conduct an evaluation by the date of activation
The Report and Order can be found online in PDF format at,
“In the RF Report and Order, the Commission anticipated that few
parties would have to conduct reevaluations under the new rules and
that such evaluations will be relatively straightforward,” the FCC
said in an April 2 Public Notice. “It nevertheless adopted a 2-year
period for parties to verify and ensure compliance under the new
The Amateur Service is no longer categorically excluded from certain
aspects of the rules, as amended, and licensees can no longer avoid
performing an exposure assessment simply because they are
transmitting below a given power level.
“For most amateurs, the major difference is the removal of the
categorical exclusion for amateur radio, which means that ham
station owners must determine if they either qualify for an
exemption or must perform a routine environmental evaluation,” said
Greg Lapin, N9GL, chair of the ARRL RF Safety Committee and a member
of the FCC Technological Advisory Council (TAC).
“Ham stations previously excluded from performing environmental
evaluations will have until May 3, 2023, to perform these. After May
3, 2021, any new stations or those modified in a way that affects RF
exposure must comply before being put into service,” Lapin said.
The December 2019 RF Report and Order changes the methods that many
radio services use to determine and achieve compliance with FCC
limits on human exposure to RF electromagnetic fields. The FCC also
modified the process for determining whether a particular device or
deployment is exempt from a more thorough analysis by replacing a
service-specific list of transmitters, facilities, and operations
for which evaluation is required with new streamlined formula-based
criteria. The R&O also addressed how to perform evaluations where
the exemption does not apply, and how to mitigate exposure.
Amateur radio licensees will have to determine whether any existing
facilities previously excluded under the old rules now qualify for
an exemption under the new rules. Most will, but some may not.
“For amateurs, the major difference is the removal of the
categorical exclusion,” Lapin said, “which means that every ham will
be required to perform some sort of calculation, either to determine
if they qualify for an exemption or must perform a full-fledged
exposure assessment. For hams who previously performed exposure
assessments on their stations, there is nothing more to do.”
The ARRL Laboratory staff is available to help amateurs to make
these determinations and, if needed, perform the necessary
calculations to ensure their stations comply. ARRL Laboratory
Manager Ed Hare, W1RFI, who helped prepare ARRL’s RF Exposure and
You book, explained it this way. “The FCC did not change any of the
underlying rules applicable to amateur station evaluations,” he
said. “The sections of the book on how to perform routine station
evaluations are still valid and usable, especially the many charts
of common antennas at different heights.” Hare said ARRL Lab staff
also would be available to help amateurs understand the rules and
evaluate their stations.”

ARRL also has an RF Safety page on its website at,
The ARRL RF Safety Committee is working with the FCC to update the
FCC’s aids for following human exposure rules – OET Bulletin 65 and
OET Bulletin 65 Supplement B for Radio Amateurs. In addition, ARRL
is developing tools that all hams can use to perform exposure

Hello Fellow Radio Operator:
Throughout amateur radio history, there has always been a tradition of radio operators and clubs to share their knowledge with others. This may be accomplish through direct communications while on the air with others or through magazines and news letters. The Tyler Amateur Radio Club (Tyler ARC) in Tyler, TX is reaching out to other clubs around the Lone Star State and other states to continue this long standing tradition shared by amateur radio operators.
As an outreach effort to other amateur radios clubs and their members, Tyler ARC is sending a courtesy copy of its newsletter “The GroundWire” to radio clubs for distribution to their respective members. The following link is to the newsletter in PDF format than can be downloaded. The GroundWire Link
You are invited to share articles on amateur radio projects or research you might have completed. Those articles can be published in The GroundWire if the article is the author’s original content and/or does not violate copyrights or is adequately cited from other publications. If you have product reviews of amateur equipment, those article will be welcomed as well.

The fast-approaching QSO Today Virtual Ham Expo March 13-14, 2021 will be even better with over 80 speakers, live kit building workshops, panel discussions, and much more. Early Bird discount tickets are still available and include entry for the Live 2 day period plus the 30-day on-demand period. Registration can be found at www.qsotodayhamexpo.com.
We are excited to share that the ARRL, the national association for Amateur Radio® in the United States, will have a significant Expo presence. ARRL CEO David Minster, NA2AA, will deliver the Keynote on Saturday, March 13, from 12-1 PT. Although only in his position since September 2020, David already has started to make a significant impact to ensure ARRL’s continuing legacy of serving radio amateurs.
David has already launched major projects and assembled teams to foster innovation and individual skill development in radio technology and communications that benefit all amateur radio operators. In his Keynote, David will share his enthusiasm for advancing amateur radio and highlight current ARRL initiatives to engage and inspire this current generation of hams. See more at https://www.qsotodayhamexpo.com/speakers.html.
In addition, the ARRL Expo booth will feature “Ask the ARRL Lab.” Engineers for the ARRL’s Lab will help answer any questions LIVE. Attendees can come into the booth lounge (featuring the Expo’s latest virtual meet-up and video technology), sit down at a virtual table, and ask members of the ARRL Lab for tips about a project they’re working on or suggestions to overcome a problem with a station installation, antenna, or a piece of gear. Attendees can also learn about equipment testing conducted by the Lab on new radios for ARRL Product Reviews.
You can participate from the convenience of your home without spending a dime on travel! So if you’ve never been to an in-person Hamfest, you can participate in the Expo and get the same benefits. The platform simulates a full convention experience.
ARRL is a QSO Today Expo Partner. FlexRadio is the Expo’s Platinum Sponsor and Gold sponsors are Elecraft, RFinder, Quicksilver Radio, Mouser Electronics, and Connect Systems.
