Amateur Radio Club Helps Teach Survival Skills

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.

Ham Families Continue to Grow

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.

ARRL member Bob Weed, W7SCY, of Bend, Oregon, shared that his family also has four

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.

  • The New Zealand Amateur Radio Transmitters Society (NZART) has announced that negotiations with Radio Spectrum Management (RSM) have been successful in obtaining a new 60 m (5 MHz) license with the same terms and conditions as the previous license which expired on May 4, 2022. With the license, New Zealand amateurs may operate on the band using the WRC-15 allocation. Maximum allowable power is 15 W effective isotropic radiated power (EIRP), and amateurs are secondary users in the band. Existing 60 m sub-license holders do not need to reapply. More information is available on the NZART website:

In Brief...
Two videos introducing the ARRL Foundation Club Grant Program are now available. The ARRL Foundation Club Grant Program, funded by a grant from Amateur Radio Digital Communications (ARDC), will make $500,000 available to clubs, enabling them to more easily provide and expand club projects, including those that will have a transformative impact on amateur radio, create public awareness and support for amateur radio, and have an educational and training impact. The program will provide up to $25,000 for worthy club projects. A recording from an ARRL webinar introducing the program, which aired on May 4, 2022, is available on ARRL's YouTube channel. A second video, presented by Jason Johnston, KC5HWB, provides a step-by-step overview of online ARRL Foundation Club Application Process. Johnston's video, published on May 5, can be viewed on his YouTube channel, Ham Radio 2.0. More information about the Club Grant Program is available at

An unusual Morse Code story from John Ruckert, WE4IAS, in Hollywood California: "About 3 AM, I was awakened by someone sending S-O-S on their car horn. I leaped out of bed, grabbed a bathrobe, and with an extra-long metal-flashlight zoomed down a flight of stairs to our apartment buildings' carport. There I found a non-tenet young lady sitting just inside our rolling car-gate. I inquired, 'Are you the person sending S-O-S on a car horn?' She smiled, and said, 'Yes. I guessed if I just leaned on my car horn, to get someone to let me out with an electronic gate-opener, no one would respond. But you did in about 30-seconds!'"

A new YouTube video was released this week, "Two Teens, a Ham Radio, and Operation Deep Freeze."
Produced by Lance Geiger, known as The History Guy, the video chronicles two teenage hams back in the mid to late 1950's who helped keep an expedition at the South Pole, during the international Geophysical year in 1957, in touch with family and friends throughout the entire winter. Jules Madey, K2KGJ, his brother John, K2KGH (now SK) are the hams profiled and their use of phone patches and relays to pass on messages from the crew at the pole. The video presents the back story of how this all came about with frequent expeditions by the US Navy to begin setting up a polar base.

Solar activity was lower this week, even though sunspots were visible every day.

Average daily sunspot numbers dropped from 109.3 to 68.6, while average daily solar flux went from 156 to 120.

Average daily geomagnetic indices were only slightly higher, with average planetary A index changing from 9.1 to 10.7, and middle latitude A index from 8 to 9.3.

Predicted solar flux looks low for the next month, even dipping below 100 in early June.

Predicted values are 135 and 138 on May 5 - 6, 145 on May 7 - 9, then 140, 130, 120, 115 and 120 on May 10 - 14, 125 on May 15 - 18, 127 on May 19 - 20, then 130, 128, 125, and 122 on May 21 - 24, 118 on May 25 - 26, then 114 and 110 on May 27 - 28, 105 on May 29 -31, then 102 and 100 on June 1 - 2, 97 on June 3 -5, then 99, 102 and 108 on June 6 - 8.

Predicted planetary A index is 5 on May 5 - 12, then 8, 10 and 8 on May 13 - 15, 5 on May 16 - 19, then 12 and 8 on May 20 - 21, 5 on May 22 - 23, 18 on May 24, 15 on May 25 - 27, then 8, 15 and 8 on May 28 - 30, and 5 on May 31 through June 8.

These predictions are from forecasters Housseal and Dethlefsen of the USAF 557th Weather Wing.

Sunspot numbers for April 28 through May 4, 2022, were 118, 90, 50, 36, 69, 53, and 64, with a mean of 68.6. 10.7 cm flux was 132.2, 123.5, 119.7, 109, 111.9, 113.8, and 130.1, with a mean of 120.
