Members of the All Things Amateur Radio Association (ATARA-W8ATR), a family-oriented radio club in the foothills of southern Ohio, were in Lancaster on Saturday, April 30, to help support the Afterschool Programs of Lancaster with their Family Survival Day at Alley Park.

Along with some radio related activities, ATARA provided instruction for the National Association for Search and

Rescue's Hug-A-Tree program, explained what to do if you are lost in the woods, as well as taught families how a trash bag can keep you warm and dry. There were also primitive fire-starting demonstrations where families could learn how to use magnesium bars, char cloth, and jute.

The families visited a Parks on the Air® (POTA) station and listened as contacts were made across the country with stations in the Dominican Republic and Puerto Rico. Oscillating Keyers were also set up for the families to key their names in Morse code.

There were 80 participants and 30 volunteers. ATARA is an ARRL Affiliated Club.

Our news story, "One Family Celebrates Generations of Amateur Radio Operators," in the April 29 ARRL Letter has generated great interest among members of the ham community. This story includes four generations of Stewart family amateur radio operators, spanning nearly 60 years.

generations of hams.

Weed was the first to be licensed in 1951, and 2 years later, his father Chet Weed, WN7TLQ/W7TLQ (SK), earned his license. In 1954, Grandfather Oscar Weed, WN7ZKJ/W7ZKJ (SK), also became a ham. Later, in 1965, Bob's younger brother Roger became licensed as KN7AEF/K7AEF, later as KL7HOT, and currently holds the call sign KV4I.

The Weed's ham roots continued to grow when his stepson Ron Bertram, KF7RB, earned his license. To complete the family tree, Bob's wife Nora is now licensed as NW7CQ, and his daughter-in-law Dawn Bertram is licensed as KJ7CHG.

ARRL RF Safety Committee members to be honored by the Radio Society of Great Britain

Chairman of the ARRL RF Safety Committee (RFSC) Gregory D. Lapin, N9GL, Ph.D, P.E., will receive an award at the 2022 Dayton Hamvention^® from the Radio Society of Great Britain (RSGB). He will receive the Founders' Trophy, recognizing his outstanding service to the society. He will also be accepting awards for committee members Kai Siwiak, KE4PT; Ric Tell, K5UJU, and Matt Butcher, KC3WD.

Along with members of the RSGB, the ARRL RFSC members formed an EMF Oversight Group, which has been meeting since August 2020 to help develop tools and procedures for complying with the new RF Exposure regulations for amateur radio operators in Great Britain. The new rules in the UK are similar to those already in effect in the United States. The new rules will be phased in over a 2-year period and are currently in effect for high band frequencies only.

RSGB members of the EMF Oversight Group are John Rogers, M0JAV (RSGB Director); Peter Zollman, G4DSE, and Ian White, GM3SEK, who received their awards at the society's annual general meeting on April 23, 2022, during an online ceremony.

ARRL Forum at Hamvention Will Include FCC Enforcement Bureau's Lark Hadley, KA4A

Federal Communications Commission (FCC) Enforcement Bureau Regional Director Lark Hadley, KA4A, will participate in an ARRL-sponsored forum at Dayton Hamvention® on Saturday, May 21, 2022. The forum, "Good Operators and the ARRL Volunteer Monitor (VM) Program" will be led by Riley Hollingsworth, K4ZDH, who heads the VM Program - a joint initiative between ARRL and the FCC to enhance compliance on radio spectrum allocated to the Amateur Radio Service.

Hadley is responsible for the FCC Field Offices in Region Three, which responds to enforcement issues involving wireless and broadcast interference in the western states of Arizona, California, Colorado, Idaho, Kansas, Montana, North Dakota, Nebraska, New Mexico, Nevada, Oregon, South Dakota, Utah, Washington, and Wyoming, and including Alaska, Hawaii, and the Pacific island territories.

Hollingsworth, who retired from FCC in 2008 as the Special Counsel for the Spectrum Enforcement Division, works with ARRL's core of volunteer VMs to recognize exemplary "good operator" behavior on the air, while also deterring poor operating practices. The VM Program will also refer well-documented instances of repeated violations to FCC, such as unlicensed use of amateur radio spectrum and deliberate interference, and follow-up on FCC requests to the program.

A complete list of ARRL-sponsored forums at Dayton Hamvention is published at www.arrl.org/expo.
