From ARRL Web:
09/02/2021 – ARRL has responded to an Orlando, Florida, news story on August 23, 2021 by WFTV Channel 9 alleging a radio amateur was told to remove his antenna by the management of his subdivision following a complaint made by a neighbor.
“The news story appears to stem from a 2-year-old complaint from a neighbor who believed her insulin pump had malfunctioned due to the radio amateur’s operations ‘a few doors down,’” said ARRL Laboratory Manager Ed Hare, W1RFI. “The story is lacking any details or timeline, so I contacted the radio amateur involved for information, and volunteered ARRL’s assistance.”
Hare explained that medical devices such as insulin pumps are regulated by the US Food & Drug Administration (FDA) specifically for electromagnetic compatibility (EMC) purposes and are expected to be capable of operating in all the RF environments likely to be encountered by consumers. FDA published guidance for its staff and industry defines EMC with respect to electrically powered medical devices “as the ability of a device to function safely and effectively in its intended electromagnetic environment, including immunity to electromagnetic disturbance (interference).” FDA review of EMC information submitted with a device for approval “is based on the risk associated with EMC malfunction or degradation of the device under review, as well as the use of appropriate FDA-recognized standards or appropriate consensus standards.”
Hare noted there is an FDA recall for the model number of the insulin pump in question, in approximately the same time frame. “But with so few details, there is no way of knowing whether that recall applies to the serial number used or whether the exact unit has the mechanical defect indicated in the recall notice that could cause the malfunction,” explained Hare.
It also became apparent that there is no actual evidence connecting the amateur’s transmissions to operation of the insulin pump. Hare was told that the amateur agreed to run tests to establish whether there was a cause and effect, but the neighbor declined.
Hare commented, “While there are no requirements for a radio amateur to stop transmitting due to alleged interference to a non-radio device, the preferred path with any complaint is for neighbors to work together.”
Cory Golob, KU1U, writes in the August 2021 issue of the Maine Telegraph Newsletter:
The first MESH Network Working Group meeting was held on Wednesday, July 28th. In attendance were Bill Richardson, NG1P; Brad Brown, Jr., KC1JMH; Cory Golob, KU1U; Fred Kemmerer, AB1OC; Leo Langelier, KH6JKQ; Phil Duggan, N1EP and Steve Jordan, KD1OM. We discussed a plan and vision to expand the MESH Network that NG1P started between Topsham and Brunswick on 5.8 GHz and how we can expand it in Maine and hopefully throughout New England.
We believe that getting back to our roots with RF linking is crucial as we have seen more dependence on internet linking over the past few years. This MESH Network has many possibilities including repeater linking, high speed data transfer and voice/video capabilities. The applications can be valuable for EMCOMM, Public Service Events and casual chatting.
This project will not be without any challenges as Maine has quite the topography, but we are excited to see how the adventure will unfold and benefit the hams in our state. With 5.8 GHz being threatened, it is more important now than ever that we show how well SHF can be utilized by amateur radio operators.

Good opportunity to learn about Mesh networking if anyone is interested.
Greater Manchester ARES invites other ARES groups to participate in mesh network training.
The first session is a zoom meeting on Wednesday, August 4th from 6:30 to 8:00pm. The second session is hands-on training in Goffstown on Sunday, August 15th, 9am to noon.
The Amateur Radio Emergency Data Network (AREDN – arednmesh.org) provides customized mesh software that can be flashed to commercial wifi routers, primarily in the 2.4GHz and 5GHz bands that are shared according to FCC Part 15 and Part 97 rules.
The AREDN software functions as a digital network with and without internet availability. Greater Manchester has had 5GHz nodes at Elliot Hospital and Catholic Medical Center operating continuously for 2 years. A node at the Manchester EOC was added recently. The Greater Manchester network supports email, chat, file transfer, and VOIP telephone services.
Training in August will focus on understanding how to access an AREDN network over dedicated wifi, exchanging email with Winlink Express over the network, and using the chat and simple file transfer capability built into the 5GHz routers.
Participants will use their own laptop computers with wifi capability, and with an installed browser and Winlink Express. The zoom meeting on August 4th will focus on introducing mesh networking, and configuring participant laptops for the hands-on exercise.
Those who plan to participate in the hands-on exercise should attend the zoom meting. Others interested in an introduction to AREDN mesh networks are also welcome to join the zoom meeting.
Please let me know who should be on a mailing list for additional information. I am sending this to a couple of email lists, so apologies in advance to those who receive multiple copies. Feel free to share with others. The more the merrier!

Many amateurs have requested a recording of the RF Exposure Rules presentation featuring Eastern MA Technical Coordinator Dan Brown, W1DAN on May 4, 2021. ARRL Laboratory Supervisor Ed Hare, W1RFI also participated in the call, fielding questions from the audience.
The presentation can be viewed at: <https://youtu.be/7dSieKF3rm0>.
Eastern MA Technical Coordinator Dan Brown, W1DAN, will hold another presentation addressing the new FCC RF exposure rules on May 4 at 7:30 PM using the ARRL GoToWebinar platform.
His April 27 talk was a hugely successful–a maximum number of 100 connections for the call was reached just as the discussion started. The GoToWebinar has a much higher limit and should accommodate all who are interested. ARRL Laboratory Manger Ed Hare, W1RFI, will serve as Technical Moderator on the call.
