FCC Reaffirms Nearly $3 Million Fine for Marketing Unauthorized Drone Transmitters
In a Memorandum Opinion and Order (MO&O) released June 17, the FCC denied a Petition for Reconsideration filed by HobbyKing of a $2,861,128 fine for marketing noncompliant RF equipment and for failing to respond to FCC orders in its investigation of the company’s practices. In the same step, the FCC enforced its equipment marketing rules. The fine resulted from an FCC investigation initiated by ARRL’s January 2017 complaint that the HobbyKing equipment was “blatantly illegal at multiple levels.”
A representative of the ARRL Electromagnetic Compatibility Committee (ECC) stated, “The Forfeiture Order is the final chapter of a story that started with a report to the ARRL Board by the EMC Committee in 2017, as a result of the discovery that aerial drone TV transmitting equipment was being imported and marketed without proper FCC authorization under FCC Part 15 rules.”
The Electromagnetic Compatibility Committee was credited in the complaint with calling attention to the issue and prompting ARRL’s action.
As spelled out in ARRL’s 2017 complaint, the ARRL Laboratory had documented that the operating frequencies of these drone TV transmitters near the 1.3 GHz amateur band were dip-switch selectable for frequencies internationally assigned for use by Aeronautical Navigation, GPS, GLONASS L1, ATC Mode “S,” as well as to both the interrogation and reply frequencies used for Air Traffic Control Air-Route Surveillance “transponder” radar systems.
ARRL’s complaint noted that given the channel configuration, these units would not have a legitimate amateur radio use, and that the marketing was directed at drone enthusiasts and not to licensed radio amateurs. “ARRL Laboratory tests did prove that only one of the seven available channels was within the 1.3 GHz amateur band,” the ECC representative said.
“This is another example of ARRL not only affirmatively acting to protect our members’ interests, but also acting to protect the safety and security of vital services and the general public,” the ECC representative said.
HobbyKing had denied that it was marketing its drone transmitters to US customers, but as the ARRL January 2017 complaint pointed out, ARRL Laboratory Manager Ed Hare, W1RFI, was able to purchase two drone transmitters from HobbyKing for testing in the ARRL Lab. “The FCC noted that amateur radio equipment used to telecommand model craft are limited to 1 W (1,000 mW), but three transmitters included in the FCC investigation operated at significantly higher power levels of 1,500 mW and 2,000 mW,” ARRL said.
HobbyKing had told the FCC that it had no notice of the Commission’s authorization requirements; that the Fifth Amendment relieved HobbyKing of its duty to respond; that the forfeiture amount was inappropriate because its parent company, Indubitably, Inc., lacked the ability to pay to the Forfeiture Order; and that the Commission was time-barred from taking action against ABC Fulfillment Services LLC because it was not part of HobbyKing’s business.
“Upon review of HobbyKing’s Petition for Reconsideration and the entire record, we find no basis for reconsideration because the petition fails to present new information warranting reconsideration,” the FCC said in the MO&O.
HobbyKing is the trade name of two US-based companies that include ABC Fulfillment Services LLC and Indubitably, Inc. Read an expanded version.
New Section Managers Appointed in Orange and Eastern Washington
Carl Gardenias, WU6D, of Perris, California, is retiring as ARRL Orange Section Manager (SM) after serving in the position since 2003. His term of office had expired at the end of March, but he agreed to continue serving as SM until a successor was chosen.
A re-solicitation for Section Manager nominations in the Orange Section was issued this past spring. The only nominee responding by the June 4 deadline was Bob Turner, W6RHK, also of Perris, California. Turner’s elected 2-year term of office does not officially begin until October 1, and Gardenias has said he wished to step down as Section Manager at the end of June.
In accordance with the Rules and Regulations of the ARRL Field Organization, ARRL Field Services Manager Mike Walters, W8ZY, has appointed Turner to start his term of office as the Orange Section Manager earlier than scheduled, with the appointment effective July 1. Walters made his decision after consulting with ARRL Southwestern Division Director Dick Norton, N6AA, and Gardenias. Turner has been the Section Emergency Coordinator for the past 10 years.
ARRL Eastern Washington Section Manager Jack Tiley, AD7FO, will be stepping down early from his term of office that concludes on September 30, 2021. Tiley, of Spokane Valley, has been Section Manager for 2 and a half years.
Jo Whitney, KA7LJQ, was the only nominee when the June 4 nomination deadline arrived, and she was declared elected. Whitney was initially scheduled to start her term of office on October 1, but because Tiley is stepping down before the end of his term, Walters — after consulting with ARRL Northwestern Division Director Mike Ritz, W7VO — has appointed Whitney to start her term of office on July 1

WISA Woodsat Successfully Completes Stratospheric Test Flight
The world’s first wooden CubeSat successfully completed a test flight into the stratosphere earlier this month. WISA Woodsat is constructed using birch plywood panels in a 1U configuration measuring 10 centimeters squared. Nine small solar cells will power the satellite, which will orbit at an altitude of 500 – 550 kilometers. The novel spacecraft will carry several amateur radio experiments, as well as photo downlinking, including selfies. A goal of the project is to determine how well wood products will perform in space.
During the recent test, a functional model of the WISA Woodsat climbed 19 miles into the sky tethered to a weather balloon. The satellite’s camera captured a selfie video of the balloon bursting. A parachute deployed to take the nanosatellite back to Earth, where it was recovered intact, lodged in a spruce tree.
The test satellite and a duplicate “spare” version, were manufactured at UPM Plywood’s Savonlinna, Finland, factory. The company sells its construction-grade panels under the WISA trademark. The panels were thermo-vacuum dried and processed on a CNC machining center.
The wooden satellite is based on a basic, versatile CubeSat format, Kitsat, which is designed with educational use in mind.
As the sponsor quipped, “WISA Woodsat will go where no wood has gone before. With a mission to gather data on the behavior and durability of plywood over an extended period in the harsh temperatures, vacuum, and radiation of space in order to assess the
use of wood materials in space structures.”
Once in orbit, Woodsat will be able to extend its selfie stick to capture photographs of the wooden box as it hurtles through space at 40,000 kilometers per hour (24,800 miles per hour). This will allow the mission leaders to monitor the impact of the environment on the plywood.
The satellite would downlink its telemetry and images from two cameras using amateur radio frequencies. In addition to testing plywood, the satellite will demonstrate accessible radio amateur satellite communication; host several secondary technology experiments; validate the Kitsat platform in orbit, and popularize space technology.
Russian Woodpecker Antenna Array Now a Cultural Heritage Site
The massive Duga-1 antenna array that transmitted the obnoxious and infuriating “Russian Woodpecker” HF signal from the 1970s until the late 1980s is now a cultural heritage site. The array, located near Chernobyl in Ukraine, was part of an over-the-horizon radar (OTH-R) system designed to detect and offer early warning of incoming ballistic missiles from the US. A complementary receiver site was located some 40 miles away. While the system was operating, its broad rat-a-tat signal, typically at a 10 Hz rate, caused severe interference in the amateur bands. The Chernobyl nuclear power plant disaster and the end of the Cold War preceded the end of the system and the interference it caused. NATO military intelligence discovered and photographed the structure, which it dubbed “Steel Yard.”
Nearly 2,300 feet long and more than 450 feet tall, the steel beams of the radar array are in the Chernobyl exclusion zone tower above the surrounding forest. Seen from a distance, it appears to be a massive wall or the start of a cage. As Vice recently reported, the Association of Chernobyl Tour Operators was the first to announce that Ukraine had made Duga-1 a protected heritage site. The Russian Interfax news service later reported the official designation.
“Our heritage is not only the area around the power plant but also the buildings located on its territory,” Oleksandr Tkachenko, Ukraine’s Minister of Culture and Information Policy, said in a Telegram thread about the announcement. “So now we are working on identifying other
objects that should be part of the list of monuments. Our goal is to prevent destruction when possible.”
The Soviet Union deployed two similar OTH-R installations — known and Duga-1 and Duga-2 — the one near Chernobyl and another in eastern Siberia. Transmitter power levels were rumored to be in the 10-megawatt EIRP range.
Duga-1 was the focus of a 2015 documentary, The Russian Woodpecker, by Chad Gracia. The film includes interviews with Duga Commander Vladimir Musiets and others involved in building and operating the OTH-R system. The production was a 2015 Sundance Film Festival winner in the documentary category. In recent years, the Duga-1 radar has also played a role in other films, as well as in various video games and novels.

Youth on the Air Camp 2021 to be On the Air and Streaming Selected Events Online
The first Youth on the Air (YOTA) camp for young radio amateurs in North, Central, and South America begins on July 11 in West Chester, Ohio. Among other activities, campers will be operating special event station W8Y from both the National Voice of America Museum of Broadcasting in West Chester Township and from the camp hotel. The camp will run until July 16.
“We are at 23 campers,” said Camp Director Neil Rapp, WB9VPG. “We are very excited to finally bring this program to the Americas. Our young people are bringing an incredible lineup of hands-on sessions for their peers. We hope this pilot gives us the information we need to replicate this camp over multiple locations for years to come. We also hope this brings a more robust community of young hams into amateur radio.”
The long-awaited summer camp for up to 30 hams aged 15 through 25 had been set to take place in June 2020, but it had to be rescheduled until summer 2021 because of COVID-19 pandemic concerns. The camp for young hams in the Americas took its cue from the summer Youngsters on the Air camps held for the past few years in various IARU Region 1 countries.
W8Y will be on the air as campers complete projects, between sessions, and during free time. Dedicated operating times on HF will be Monday, July 12, 0100 – 0330 UTC; Tuesday, July 13, 0000 – 0330 UTC and 1800 – 2130 UTC. Dedicated satellite station operating times will be Thursday, July 15, 1400 – 1700 UTC, and Friday, July 16, 1500 – 1700 UTC.
An Amateur Radio on the International Space Station (ARISS) contact is currently set for either Wednesday, July 14, at 1503 UTC, or
Thursday, July 15, at 1416 UTC. It will be streamed live on the Youth on the Air YouTube channel. The camp opening observance on Sunday, July 11, 2100 – 2230 UTC, will feature keynote speaker Tim Duffy, K3LR. The hour-long closing ceremony on Friday, July 16, will get under way at 1700 UTC. The YouTube channel will also feature a daily video highlighting the activities of the previous day.
ARRL and The Yasme Foundation donated project kits for the campers. X Tronics provided temperature-controlled soldering stations. The brochure on the Youth on the Air website includes more details about the camp. For additional information, contact Camp Director Neil Rapp, WB9VPG.

Moonbounce enthusiast Steve McDonald, VE7SL, wanted to determine a back-to-basics equipment complement for making 2-meter EME contacts. He came up with a nine-element Yagi, a 120 W amplifier, and an antenna position-control system that offered azimuthal rotation but not elevation. The time available to make EME contacts was less than if he’d had elevation control. His blog recounts his experience with single-Yagi moonbounce. His advice, “If you haven’t given single-Yagi EME a try, I would encourage you to test it out, as you might be surprised at your results.” The next ARRL EME Contest weekend is October 23 – 24, 2021.
