ARRL Board Meets in Remote Session
Due to travel and gathering restrictions in place because of the coronavirus pandemic, the ARRL Board of Directors met on Friday, July 17, in a remote session, using the Zoom videoconferencing platform.
During this session, the Board took the following actions:
The meeting ended with the Board recessing until a future, as-yet-undetermined date, when the meeting will be concluded. That is expected to be in 4 to 5 weeks, depending on circumstances and the ability to arrange a suitable meeting site. Minutes will be released once the meeting is concluded.
Traffic-Handling Webinar Launches Ham Radio Learning Series
A live presentation from ARRL North Texas Section Traffic Manager Aaron Hulett, K8AMH, inaugurated the new ARRL Learning Network on Tuesday, July 28. The webinar series features 30-minute presentations from experienced members covering a variety of amateur radio topics and interests. Hulett’s webinar, “Relay Stations and the Art of Traffic Handling,” introduced techniques and skills
“Aaron hit a home run,” said Bob Inderbitzen, NQ1R, ARRL Product Development Manager and moderator for Hulett’s webinar. “His presentation was the perfect balance of knowledge-sharing and enthusiasm that will surely motivate other members to try their hand at traffic handling.” A recording of the webinar is available for members to view.
The webinars are hosted using GoToWebinar. Members are invited to ask questions during each webinar, and a 15-minute Q&A period follows each presentation for those who can participate longer. A running list of upcoming live presentations is available below and on the ARRL Learning Network web page. Prospective attendees may register on that same page. ARRL members must first log into the ARRL website.
Inderbitzen encourages other members to be considered for future ARRL Learning Network webinars by inviting them to complete a Call for Speakers form. “It’s all about members helping members. What better way to grow greater participation in amateur radio!”

The Sport of Finding Hidden Transmitters on Foot

Propagation as a Matter of Life or Death
On May 25, 1928, the airship Dirigible Italia crashed on pack ice northeast of the Svalbard Islands on the return leg of a trip to survey the North Pole with 16 passengers and crew on board. At impact, one person was killed, and the cabin carrying nine people separated from the hydrogen-filled airframe. Six crew members on the dirigible structure were never seen again, after the airship again became airborne. The survivors on the icepack turned to their 5 W wireless set, a one-tube Hartley oscillator, to put out
The recently published article, “The Shipwreck of the Airship Dirigibile Italia in the 1928 Polar Venture: A Retrospective Analysis of the Ionospheric and Geomagnetic Conditions,” provides the gripping historical context and tries to explain why it was so difficult to establish communication for a rescue. Drawing from sources of geophysical data collected at the time, and using modern theories of propagation — including some directly derived from amateur radio observations — the authors present data including sunspot count, magnetic flux, and F2 layer height, and take the reader through an analysis of the sky-wave and ground-wave paths.
Ultimately, the authors suggest, ground-wave path losses likely exceeded 100 dB, leaving only skywave as a potential link. In the first few days after the crash, the ionospheric path was impossible at the frequencies being used — 9.1 and 9.4 MHz — due to disturbed conditions. It was only after conditions had settled that communication became possible, and it only became reliable when a lower frequency was chosen.
Even after communication was established, 15 rescuers were lost in the search and recovery operations, including Roald Amundsen, Norway’s famed polar explorer. Finally, on July 12, 1928, 48 days after the initial crash, a Russian icebreaker was able to reach and rescue the survivors. — Thanks to The ARRL Contest Update

Hurricane Watch Net Activates for Hurricane Hanna
The Hurricane Watch Net (HWN) activated on July 25 for Hurricane Hanna, the first hurricane of the Atlantic hurricane season. When the net activated, the storm was poised to make landfall along the Gulf of Mexico as a Category 1 storm, with maximum sustained winds of 75 MPH. After it came ashore on the Texas coast, extensive property damage was reported in the Rio Grande Valley, the brunt of it south of Corpus Christi, which experienced storm-surge flooding and tropical storm winds. Areas to the south saw sustained hurricane-force winds.
“The year 2020 has been a strange year in every way, and the weather is no different,” HWN Manager Bobby Graves, KB5HAV, said last weekend. “Just a few hours ago, it looked as though we would be
The net activated on 14.325 MHz — its primary net frequency — and operated simultaneously on 7.268 MHz. The HWN remained active for several hours, working in cooperation with WX4NHC at National Hurricane Center (NHC).
HWN volunteers gather observed ground-truth weather data from the affected area. “We are also available to provide backup communication to official agencies such as emergency operations centers, Red Cross officials, and storm shelters in the affected area,” Graves added. In addition, the HWN collects and reports significant damage and storm surge data to forecasters and FEMA officials stationed at the National Hurricane Center.
FCC Fines HobbyKing Nearly $3 Million for Marketing Unauthorized Drone Transmitters
The FCC has issued a Forfeiture Order (FO) calling for HobbyKing to pay a fine of $2,861,128 for marketing drone transmitters that do not comply with FCC rules. An FCC Enforcement Bureau investigation stemmed in part from a 2017 ARRL complaint that HobbyKing was selling drone transmitters that operated on amateur and non-amateur frequencies, in some instances marketing them as amateur radio equipment. The fine affirms the monetary penalty sought in a June 2018 FCC Notice of Apparent Liability (NAL).
The FCC said its investigation found that dozens of devices marketed by the company transmitted in unauthorized radio frequency bands and, in some cases, operated at excessive power levels. “Such
“We have fully considered HobbyKing’s response to the NAL, which does not contest any facts and includes only a variety of legal arguments, none of which we find persuasive,” the FCC said in the FO. “We therefore adopt the $2,861,128 forfeiture penalty proposed in the NAL.”
The FCC pointed out in the FO that it has previously made clear that “[d]evices used in the Amateur Radio Service do not require authorization prior to being imported into the United States, but devices for other services, including the CB service, require Commission approval.” The FCC investigation found that 65 models of devices marketed by HobbyKing should have had FCC certification.
Responding to the NAL, HobbyKing claimed to have ceased marketing the 65 models the FCC identified, but promised only to make “best efforts” not to market other noncompliant RF devices. Read more.
The K7RA Solar Update
Tad Cook, K7RA, Seattle, reports: Sunspots finally have returned! Currently, two sunspots are visible, both from new Solar Cycle 25. The daily sunspot number was 11 on July 21 – 27 and is currently 22. We’ve noticed an improvement in propagation recently, due to seasonal sporadic-E activity.
Total sunspot area covered 80 millionths of the solar disc on July 21, 120 millionths on July 22 — 26, and the coverage on the following 3 days was 70, 50, and 85.
Geomagnetic indicators were a bit more active, with average daily planetary A index rising from 3.9 to 6.7, while average daily mid-latitude indicators rose from 4.3 to 8.7.
Predicted solar flux is 72 on July 30 – August 6; 68 on August 7 — 22; 69 on August 23 — 28, and 68 on August 29 – September 7.
Predicted planetary A index is 5 on July 30 – August 23; 8 on August 24 — 25, and 5 on August 26 – September 7.
Sunspot numbers for July 23 – 29 were 11, 11, 11, 11, 11, 22, and 22, with a mean of 14.1. The 10.7-centimeter flux was 70.3, 69.5, 70.4, 71.4, 71.4, 71.8, and 72.6, with a mean of 71.1. Estimated planetary A indices were 4, 11, 15, 3, 4, 5, and 5, with a mean of 6.7. Middle latitude A index was 4, 13, 27, 3, 5, 5, and 4, with a mean of 8.7.

AMSAT Partners with University of Maine WiSe-Net Lab to Develop State’s First CubeSat
The University of Maine Wireless Sensing Laboratory (WiSe-Net Lab) and AMSAT have signed an agreement to collaborate on building and operating MESAT1, Maine’s first small satellite. Carrying an amateur radio payload in addition to science payloads, MESAT1 is set to launch sometime in the next 3 years under NASA’s CubeSat Launch Initiative (CSLI), which provides opportunities for nanosatellite science and technology payloads built by universities, schools, and nonprofits to ride-share on space launches. AMSAT President Clayton Coleman, W5PFG, celebrated the announcement.
“This is a great day for AMSAT and UMaine’s WiSe-Net Lab,” Coleman said. “This partnership is a true win-w
MESAT1 will be one of 18 small research satellites selected by NASA to carry auxiliary payloads into space between 2021 and 2023. The CubeSat is being developed in partnership with the University of Maine (UMaine) and the University of Southern Maine (USM), along with a trio of K – 12 schools. UMaine graduate students and USM undergraduates will collaborate on CubeSat design, development, integration, and testing.
Established in 2005, UMaine’s WiSe-Net Lab is involved in aerospace and space research. The lab was founded by Ali Abedi, KB1VJV, Assistant Vice President for Research and Director of the Center for Undergraduate Research at the university’s main campus in Orono. Lab researchers have developed the first wireless sensor network for NASA’s lunar habitation project and launched wireless leak detection to the International Space Station.
The MESAT1 initiative will enable K – 12 students and teachers in Maine to access space data for educational and research
AMSAT will provide a linear transponder module (LTM) along with integration and operational support for MESAT1. AMSAT’s LTM incorporates a VHF/UHF telemetry beacon, command receiver, and linear transponder. It will be available for worldwide amateur radio use once the satellite is commissioned. — Thanks to AMSAT and the University of Maine
