Louisiana ARES Returning to Normal Status in Storm-Affected Parishes

Louisiana ARES Section Emergency Coordinator James Coleman, AI5B, said this week that ARRL Amateur Radio Emergency Service® (ARES®) teams in his Section "should now be on normal status, with the affected parishes' status as appropriate for local conditions." Emergency Coordinators in some hard-hit parishes have activated volunteers for relief and recovery operations. More than 30 parishes were affected by the storm, although cell telephone outages in the affected area now stand at 3.7% as of September 8 and recovering rapidly. All 911 systems were reported operational as of September 8.

The Louisiana ARES Emergency Net is now on standby. "If it becomes necessary, the net will be active from 2 PM to 6 PM CDT on 7.255 MHz, and from 6 PM to 10 PM CDT on 3.878 MHz," Coleman's report said. The Louisiana Traffic Net is operating 7 days a week at 6 PM CDT on 3.910 MHz.

ARRL Headquarters shipped Ham Aid kits to Louisiana Region 3 for use during recovery efforts. Region 3 District Emergency Coordinator (DEC) Miriam Barrett, KG5BNH, and St. Mary Parish's Emergency Coordinator Jacki Price, KA5LMZ, have coordinated their efforts to assist the Council on Aging in Terrebonne Parish. The Ham Aid kits include equipment for HF, VHF, and UHF, including handheld transceivers and "base-station antennas.

The W5RAR VHF repeater (146.805 MHz) was in use over a four-parish area -- La Fourche, St. Charles, St. John, and Terrebonne -- that suffered significant wireless system damage as well as a 911 system outage in St. John Parish. The St. Charles Emergency Operations Center (EOC) was transmitting requests via the Livingston Wide Area Repeater Network (LWARN) 440 MHz linked repeater system to WB5LHS.

A communications team in support of Florida Baptist Disaster Relief established operations in a communications trailer at the Metairie Baptist Church. The Jefferson Parish Emergency Operations Center (EOC) with DEC Nick Frederick, W4NDF, and the City of Kenner EOC with Mary Vernoy, WB5IOE, assisting maintained a VHF net. Kenner's fiber optic cable that provided internet was cut by Entergy so it could access one of its lines for repair. That left "two erratic cellphones and a VHF net" as the only communications Kenner had with Jefferson Parish. Vernoy had to climb onto the roof of the EOC to pick up the 2-meter antenna that had been knocked down by the wind. She was cheered by the arrival of the Baptist team from Florida.

Gordon Gibby, KX4Z, reported that Metairie was hard-hit, with power outages and boil water notices, although the areas around hospitals have had power restored. "Hams can be a big benefit by partnering with organizations like Florida Baptist and work to meet their specific communications needs," said Gibby, who has connections with the Florida group that drove from Florida to help out. He said hams were embedded within the volunteer organization.

A report from Tangipahoa Parish said that as weather conditions deteriorated on August 29 -- the day Hurricane Ida made landfall -- local repeaters lost power and went on battery backup. Two repeaters were lost when a tower collapsed. Formal weather nets were not conducted to conserve power for emergency transmissions only. As of September 6, both the WB5NET and W5TEO repeaters remained on battery backup power and conserving power.

ARRL Board of Directors Bestows Awards

The ARRL Board granted several awards at its July 2021 meeting.

  • The ARRL Doug DeMaw, W1FB Technical Excellence Award went to Steve Franke, K9AN; Bill Somerville, G4WJS, and Joe Taylor, K1JT, for their July/August 2020 QEX article, "The FT4 and FT8 Communications Protocols." The DeMaw award honors the author of an article or article series judged to possess the highest degree of technical merit in ARRL periodicals for the past year.

  • John Levo, W8KIW, of Hillsboro, Ohio, was designated as the recipient of the 2021 ARRL Philip J. McGan Memorial Silver Antenna Award. This award honors a Public Information Officer who successfully promotes all aspects of amateur radio that enhance the understanding of amateur radio's contributions to education, public safety, and recreation. The Board said Levo's efforts over time have captured "the many avenues of opportunities of amateur radio as a hobby, an education tool, and a service for public safety."

  • The 2021 ARRL Technical Service Award 2021 award recipient is James Baxter, K0UA, of Branson, Missouri. The Board said Baxter "exemplifies the spirit of this award due to his diligent work assisting hundreds of hams to get on the air, particularly with FT8, and by spending countless hours on web sessions with them to work out their configuration issues, show them best practices, and to help track down RFI issues."

  • The Board bestowed the 2021 ARRL Technical Innovation Award on Steve Haynal, KF7O; Wojciech Kaczmarski, SP5WWP, and Roger Clark, VK3KYY. Haynal was cited as the instrumental and driving force behind the Hermes Lite 5 W HF SDR transceiver as a fully open-source hardware and software project. Kaczmarski was recognized for developing the open-source digital radio communication protocol M17, leading to the development of DROID-Star (an Android application) by Doug McLain, AD8DP. Clark was cited for spearheading a successful effort to augment a low-cost handheld radio for use by visually impaired operators, significantly lowering the cost of entry for such amateurs.

  • The 2021 Herb S. Brier Instructor of the Year Award went to David Ritter, ND4MR. ARRL sponsors this award in conjunction with the Lake County Indiana Amateur Radio Club in Brier's memory to recognize superior amateur radio instruction and recruitment. An ARRL Member for nearly 40 years, Ritter is an ARRL Registered Instructor and a full-time faculty member at Wilkes Community College in North Wilkesboro, North Carolina, where he's been the lead -- and sole -- Technician licensing course instructor since 2010.

GENESIS Satellites among Payloads Lost in Launch Failure

The GENESIS-L and GENESIS-N ham radio satellites were among several carrying amateur radio payloads lost following the failure of the Firefly Alpha rocket during its first launch on September 2 from the Vandenberg Space Force Base in California. This was sad news for AMSAT-EA (Spain), as GENESIS-L and GENESIS-N were the first satellites they had built themselves.

According to the AMSAT-EA website, the GENESIS satellites were destroyed after the Firefly Alpha vehicle presented an anomaly as it hit a velocity of Mach 1 and reached Max Q, a point of maximum aerodynamic pressure on the vehicle. The launch had been halted a few seconds before takeoff, but the countdown was subsequently resumed.

GENESIS-L and GENESIS-N were to conduct a series of telecommunications-related experiments, while a ground-station analysis of the received signals would try to attain Doppler variations in order to perform orbit determination and satellite identification from radio amateur stations around the world.

California Club Assists Animal Rescue Group with Communication Support

The El Dorado County Amateur Radio Club (EDCARC) has been providing radio communication support for small and large animal rescue efforts during the Caldor Fire. Members of the South County Large Animal Rescue (SCLAR) group, El Dorado County Animal Services, and other volunteers have been addressing the need. Many of the EDCARC volunteers are also members of the Club's Neighborhood Radio Watch program.

As the California Caldor Fire destroyed the community of Grizzly Flats, threatened Lake Tahoe, and caused evacuations in dozens of communities throughout the county, thousands of area residents were forced to flee their homes without having time to round up their pets and livestock.

"We desperately love our animal companions, whether big or small, and being separated and unable to care for them in the midst of a disaster is truly heart-wrenching," said Alan Thompson, W6WN, the club's Public Information Officer. "Because of the mountainous terrain, many of our neighborhoods already had little or no cell or internet communication, and the fire only made things worse."

Thompson said the club quickly deployed its Mobile ARRL Amateur Radio Emergency Services (ARES®) Communications Center, maintained by Jay Harmor, KE6GLA, which is in service as central net operations. Several members stepped up, including Dale Dennis, KJ6HHY, from Yolo ARES, and Tom Newman, NN6H, from Alameda County Radio Amateur Civil Emergency Service (RACES®) and part of the Alameda County Sheriff's Communications Team. They volunteered their time and radios to accompany the animal rescue teams dispatched into impacted areas.

Teams of SCLAR members, Animal Services personnel, public employees, and radio communications staff have been conducting daily animal rescue missions and welfare checks throughout the impacted areas. Until residents are permitted to return, these teams are providing food, water, and care to abandoned animals.

Thompson said those seeking an animal evacuation or welfare check should contact El Dorado County Animal Services -- western slope, (530) 621-5795 or the shelter at (530) 621-7631. In the South Tahoe area, call (530) 573-7925.

SCLAR will respond as directed by El Dorado County Animal Services. They cannot self-deploy or respond directly to phone calls for assistance, Thompson said.

Nathaniel Frissell, W2NAF, Awarded $481,260 NASA Research Grant

Ham Radio Science Citizen Investigation HamSCI founder Nathaniel Frissell, W2NAF -- an assistant professor in The University of Scranton's Physics and Engineering Department -- has been awarded a $481,260 grant through the NASA Space Weather Applications Operations Phase II Research Program. Frissell will serve as principal investigator for a research project entitled, "Enabling Space Weather Research with Global Scale Amateur Radio Datasets." He'll collaborate with Philip Erickson, W1PJE, of the Massachusetts Institute of Technology Haystack Observatory and Bill Engelke, AB4EJ, at the University of Alabama.

"This grant includes significant funding for participation of Scranton undergraduate students in this research, as well as support for new computation resources," Frissell said. He explained that the grant will fund "the development of an empirical model for the prediction of traveling ionospheric disturbances (TIDs) in high-frequency radio communications while investigating the geophysical drivers of these disturbances." The grant will cover 2 years of work.

Frissell said that the predictive, empirical TID models will be developed using data collected by the Reverse Beacon Network, WSPR, and PSKReporter -- automated, global-scale radio communication observation networks operated by the amateur radio community. Undergraduate students will help the faculty researchers to create algorithms used for the model development.

This new NASA award complements a 5-year National Science Foundation grant of more than $616,000 that Frissell received in 2020. That investigation aims to understand the source of TIDs observed in amateur radio and other scientific datasets.

In 2019, Frissell received a $1.3 million National Science Foundation grant to fund a 3-year initiative to measure modulations produced in the Earth's upper atmosphere.

This is Frissell's second NASA grant. Read an expanded version.


The K7RA Solar Update

Tad Cook, K7RA, Seattle, reports: Sunspot activity increased dramatically this week. Sunspot numbers peaked at 87 on September 8, and on September 7, solar flux was 101.2.

Average daily sunspot numbers rose by 14, to 64.6, while average daily solar flux increased from 88 to 92.9. New sunspots appeared on September 2 and 3, and three new sunspot groups arrived on September 4. Another new one appeared on September 8, and on that day the total sunspot area was 1,000 micro-hemispheres.

Both the daily planetary and middle latitude A index reached a high of 14 on September 8. The averages were 7 and 7.7, down from 9.6 and 10.7 last week.

Predicted solar flux looks quite promising, at 100 on September 9 - 11; 98 on September 12; 95 on September 13 - 16; 85 on September 17 - 18; 88 on September 19 - 23; 90 on September 24 - 28; 88 on September 29 - October 1; 86 on October 2; 90 on October 3 - 6; 92 and 90 on October 7 - 8, and 85 on October 9 - 15. Flux values may rise to 90 again after October 20.

Predicted planetary A index is 8 on September 9; 5 on September 10 - 20; 8 on September 21; 5 on September 22 - October 1; 8 on October 2 - 3, and 5 on October 4 - 17.

On Sunday September 5, Spaceweather.com reported, "The sudden profusion of so many sunspots is a sign of strength for young Solar Cycle 25. The solar cycle is actually running ahead of schedule. NOAA and NASA predicted that it will peak in the year 2025. Outbreaks like this one support the idea that solar max could come a year early."

On September 8, Spaceweather.com reported a shortwave blackout over the Pacific Rim caused by a coronal mass ejection (CME) on September 8 at 1736 UTC.

Sunspot numbers for September 2 - 8 were 33, 33, 68, 66, 80, 85, and 87, with a mean of 64.6. The 10.7-centimeter flux was 85.8, 83.8, 86.5, 93.3, 99.5, 101.2, and 100.4, with a mean of 92.9. Estimated planetary A indices were 4, 6, 5, 6, 6, 8, and 14, with a mean of 7. Middle latitude A index was 3, 6, 5, 8, 8, 10, and 14, with a mean of 7.7.

A comprehensive K7RA Solar Update is posted Fridays on the ARRL website. For more information concerning radio propagation, visit the ARRL Technical Information Service, read "What the Numbers Mean...," and check out the Propagation Page of Carl Luetzelschwab, K9LA.
