Free Hiram Percy Maxim 150th Birthday Event Logging Software Now Available
Scott Davis, N3FJP, perhaps best known for the ARRL Field Day software that bears his call sign, has developed a free logging program for ARRL’s Happy 150! Hiram Percy Maxim Birthday Celebration on-the-air event that gets under way on August 31 and runs for 9 days. Davis calls his software Hiram Percy Maxim Contest Log 1.0. Maxim, 1AW, who cofounded ARRL, was born on September 2, 1869.
The Happy 150! event will begin at 0000 UTC on August 31 and continue until 2359 UTC on September 8. It is open to all radio amateurs. The goal is straightforward: Contact as many participating stations as possible. W1AW and all ARRL members will append “/150” to their call signs during this event (DX operators who are ARRL members may operate as <call sign>/150, if permitted by their country of license.) Participating stations will exchange a signal report and ARRL/RAC Section. DX stations will send a signal report and “DX.” All Amateur Radio bands except 60, 30, 17, and 12 meters are available. Permitted modes are CW, any voice mode, and digital.
Davis said Hiram Percy Maxim Contest Log 1.0 is full featured and “very easy and intuitive to use.”
“If the Hiram Percy Maxim celebration is received as strongly as it appears, my hope is that ARRL will decide to make this an annual event,” Davis allowed. “After all, birthdays come once a year, and we now have the infrastructure to continue.”
One Dead, One Injured in New Hampshire Ham Radio Tower Mishap
A tower dismantling turned tragic on Saturday, July 27, in Deerfield, New Hampshire, when two radio amateurs working some 40 feet up on the tower were carried to the ground when the structure collapsed. Joseph Areyzaga, K1JGA, 52, of Goffstown, New Hampshire, did not survive injuries sustained in the fall, while the tower’s owner, Michael Rancourt, K1EEE, 65, was seriously injured and remains
hospitalized. Rancourt was taking down the tower in preparation for selling his house, and the pair had nearly completed their work. They were tied into the tower and went down with it as it collapsed.
The tower, a tilt-over model said to be 40 to 50 feet, had been bolted to prevent it from tilting as it was being dismantled.
A law enforcement source said a number of people were at the site for a social gathering as the tower was being taken down, and they witnessed the tragedy.
No official determination has been made regarding the cause of the structural failure, but a radio amateur who visited the scene afterward observed that two of the tower’s three legs were clearly compromised and split cleanly and the third leg bent, just above the fully intact tilt base.
The New Hampshire Amateur Radio tower-related fatality is the second such deadly incident in a little more than 6 weeks. In mid-June, a Pennsylvania radio amateur died when the tower he was installing collapsed as he was attempting to attach a guy line to the structure’s bottom section.
DXpedition Team Donates Part of QSL Fees to Galapagos Conservancy
From February 28 until March 6, the HD8M Amateur Radio team operated from the side of Cerro Crocker, a volcano high above the city of Bellavista on Santa Cruz Island in the Galapagos. The HD8M team consisted of Jim Millner, WB2REM, a retired psychologist, and Bill Mims, W2WCM, a retired airline pilot. The purpose of the operation was to bring attention to the fragile ecosystem of the Galapagos Islands through their Amateur Radio activity. As a part of the confirmation process, the team exchanged QSL cards from which a dollar or more would be donated to Galapagos Conservancy.
“We used ClubLog’s Online QSL Request System (OQRS), bureau requests associated with ClubLog, and SASEs for QSLing,” Millner explained. “When stations used OQRS and requested a direct QSL Card, they were charged a $4 fee. We mentioned in the OQRS system that of every $4 received, were going to donate $1 to the Galapagos Conservancy. As it turned out, however, we donated all extra money to the Conservancy.”
At the time, the HD8M team was the only Amateur Radio operation in the Galapagos Islands, making it a rare entity, so they found themselves in high demand. In just 6 days of operation, they contacted more than 8,000 stations in 140 DXCC entities as well as in all 50 US states.
Millner and Mims operated two stations equipped with Icom IC-7300s and band-pass filters, operating on SSB, CW, and FT8, and using all wire antennas. HD8M took part in the ARRL International DX Phone and, despite poor conditions on the equator, they were able to make more than 600 contacts. “FT8 was a particularly a good mode despite the conditions,” Millner said, noting that the location at 1,500 feet elevation on the side of a volcano gave the pair “an amazing view” of the ocean and outlying islands. “The wildlife was abundant with many colorful birds and land iguanas, as well as huge Galapagos tortoises that roamed around the 10-acre property.

ARISS Next-Generation Radio System Completes Critical Flight Certification Tests
The Amateur Radio on the International Space Station (ARISS) next-generation Interoperable Radio System (IORS) successfully
The IORS also successfully passed power quality and acoustics testing, which verified that the ARISS IORS will not introduce harmful signals back into the ISS power system and is quiet enough to meet ISS acoustic requirements. ARISS Hardware Team members Lou McFadin, W5DID, and Kerry Banke, N6IZW, were at NASA’s Johnson Space Center to support the 2-week battery of tests in concert with the NASA test and certification team.
“Since the IORS is being qualified to operate on 120 V dc, 28 V dc, and Russian 28 V dc, as well as transmit on VHF or UHF, a lot of test combinations were required to cover all cases,” Banke said. “Each input voltage type was also tested at low, medium, and high line voltage. Moreover, additional permutations were required to test the IORS under no load, medium load, and full load at each voltage level. So it should not be surprising why the tests took 2 weeks to complete.”
Successful completion of these tests represents a key milestone in preparing the IORS for launch. ARISS says it now can begin final assembly of the flight units and prepare for their safety certification before launch. ARISS is working toward launch-ready status by year’s end.
Dhruv Rebba, KC9ZJX, is 2019 Newsline Young Ham of the Year
Fifteen-year-old ARRL member Dhruv Rebba, KC9ZJX, of Normal, Illinois, has been selected as the 2019 Bill Pasternak, WA6ITF, Memorial Amateur Radio Newsline Young Ham of the Year (YHOTY). His parents are Hari Rebba, VU2SPZ, and Shailaja Panyam. A rising sophomore at the Normal Community High School, Dhruv is a member of the Central Illinois Radio Club. He has been licensed since 2013, after a visit to Dayton Hamvention® with his dad sparked his interest in Amateur Radio.
After getting his license, Dhruv became involved in ARRL Field Day and public service events with the Central Illinois Radio Club, including the We Care Twin Cities Half Marathon and the Hop on for Hope Bike Ride/Walk. Dhruv says he found a way to combine his interest in space and engineering with his new hobby, joining AMSAT and pursuing his dream of a school contact with an astronaut aboard the International Space Station.
In October 2017, he served as lead control operator for an Amateur Radio on the International Space Station (ARISS) contact with students at his school, Chiddix Junior High, who spoke to astronaut Joe Acaba, KE5DAR. On July 27 of this year, Dhruv helped to facilitate another ARISS contact with Scouts attending the World Scout Jamboree in West Virginia.
ARISS presentations at Dayton and Huntsville, Dhruv’s selection as an ARISS mentor, and networking with those putting together the ARISS contact for the World Scout Jamboree led to his involvement in the July 27 contact.
Dhruv has earned many accolades for his Amateur Radio pursuits, including the Young Ham Lends a Hand Award at the 2019 Dayton Hamvention Youth Forum; a Presidential Award from AMSAT, and the Radio Club of America Young Achiever Award. He also has traveled to India to promote Amateur Radio awareness.
The Young Ham of the Year was established in 1986 by Amateur Radio Newsline cofounder Bill Pasternak, WA6ITF (SK), in 1986. Dhruv will receive the 2019 YHOTY award during the Huntsville Hamfest on August 17. Read more. — Thanks to Amateur Radio Newsline

AMSAT President Asks Members to Help Keep Amateur Radio in Space
“It takes considerable volunteer effort and real dollars to keep Amateur Radio in Spac,” AMSAT President Joe Spier, K6WAO, has reminded the organization’s members in a message that included an
“AMSAT has several fundraising needs,” Spier said, noting that contributions to AMSAT are tax deductible to the extent permitted by IRS rules. “The daily operation of AMSAT is accomplished by donations to the General Fund. The other main department needs are the fund for GOLF 3U CubeSats design/construction and Amateur Radio on the International Space Station (ARISS).”
Spier pointed to the 2018 successes of AO-92 (Fox-1D) and the launch of AO-95 (Fox-1Cliff). “AMSAT partnered with Spaceflight Inc. by contracting and paying for these launches,” Spier noted. “Fundraising for Fox-series satellites has not yet recouped this expenditure, so donations are still being accepted.” AMSAT expects to launch of RadFxSat-2 (Fox-1E), in partnership with Vanderbilt University, by the end of summer. AMSAT is also partnering with several universities to fly the same linear transponder on their CubeSats.
AMSAT has been selected for two CubeSat Launch Initiative (CSLI) opportunities for GOLF-TEE and GOLF-1. “GOLF’s 3U spaceframe is being designed with versatility to add mission-specific radios, power supplies, and experiments,” Spier noted. “A series of GOLF CubeSats will provide better coverage, and a greater footprint will allow more coverage by fewer satellites.”
IEEE Microwave Theory and Techniques Society Seeks Student CubeSat RF Hardware Proposals
The IEEE Microwave Theory and Techniques Society (MTT-S) has announced the MTT-Sat Challenge for groups of students developing RF hardware for CubeSat applications. The MTT-Sat Challenge is a worldwide competition for teams of undergraduate and graduate students to design and build RF hardware for small satellites. The most promising designs will undergo space environmental qualification testing and could be incorporated into an actual CubeSat.
At this time, the IEEE MTT-Sat Challenge is calling for ideas that could come from among the following fields: Transceivers based on commercial of the shelf (COTS) components; antenna systems and arrays for CubeSats; ground terminals for low-earth orbit (LEO) satellites; radiation-hardened electronics based on COTS components; inter-satellite communication; electromagnetic sensors for CubeSats, and novel RF technologies for space applications.
Detailed information is available on the MTT-Sat Challenge. The submission deadline is October 2, 2019, 0900 UTC (October 1, 11 PM HST). Those planning to submit proposals should send a brief letter of interest by August 31.
Cass Award Winners Announced
Janusz Wegrzyn, SP9FIH, has been named the winner of the 2018 Single-Operator Cass Awardfor the second year in a row. While active from Sint Eustatius Island as PJ5/SP9FIH in March 2018, Wegryzn contacted 8,257 unique stations during the 14 days of his one-person DXpedition.
The 3C0W Annobon Island DXpedition team was the recipient of the first Unlimited Cass Award for its effort in
logging as many DXers as possible. During March 2018, Girts Budis, YL2KL; Yuris Petersons, YL2GM, and Kaspars Uztics, YL1ZF, contacted 18,812 unique call signs on the DXpedition.
Sponsored by Club Log, DXLab, and the Northern California DX Club, the annual Cass Awards encourage DXpedition operating excellence by recognizing DXpeditions that contact the greatest number of unique call signs. Running leaderboards for the 2019 Cass Single-Operator and Unlimited awards are available on the Club Log website.
