Grace and Henri Keep Amateur Radio Weather Spotters Busy

Hurricane Grace and Hurricane Henri drew the attention of weather spotters over the past week. The Hurricane Watch Net (HWN), which tracked both storms to gather weather data for the National Hurricane Center (NHC), was able to secure operations at 1800 UTC on August 22 after watching Grace make two landfalls in Mexico.

"Things got busy -- and fast!" said HWN Manager Bobby Graves, KB5HAV. "Just before activating at 1200 UTC [on Sunday], Henri was downgraded from a Category 1 hurricane to a tropical storm. Normally, we -- HWN -- don't activate for tropical storms. However, given the wind speed at the time of activation was just shy of being a hurricane, there was a slim possibility Henri could regain Category 1 status." And, Graves noted, the storm was headed into the densely populated northeastern US. The rainfall generated by Henri, some of it record-breaking, caused heavy flooding in some areas, including New York City. That storm came ashore near Westerly, Rhode Island.

Over the weekend, Eastern Massachusetts ARES® Section Emergency Coordinator Rob Macedo, KD1CY, who also manages the VoIP Hurricane Net, announced plans for the Commonwealth in advance of Henri's arrival. These included coordination with ARES® and SKYWARN teams in the region and the Massachusetts Emergency Management Agency.

All told, the HWN racked up a combined total of 27 hours on the air -- with two activations for Hurricane Grace and two for Hurricane Henri. Graves said only one station reported from Mexico, but the net remained available to assist in any capacity needed.

It was another story for Henri. "We were not lacking reporting stations, and that's a good thing," Graves said. "While maybe not as many as we would like, we certainly had a good number checking in and forwarding their data."

He said conditions, while improved over the past few years as Solar Cycle 25 ramped up, got tough. "At times, we would experience one-way propagation. For example, on Sunday, the NCS on duty was being heard by a station in the affected area but could not hear the reporting station," Graves recounted. "His relay was able to hear the reporting station, but that station could not hear the relay. So, the NCS asked the questions, and the relay received the report. This is what's called 'teamwork.'"

Graves is grateful that Henri was not as bad as it could have been. "It never really got itself organized, unlike storms such as Sandy in 2012 and Bob back in 1991," he said. "Had Henri been another Sandy, the outcome would have been much worse."

On the other hand, Grace, which made landfall in the Mexican state of Veracruz, just south of Túxpam, as a Category 3 hurricane with sustained winds of 125 MPH, caused several fatalities. "Grace tied a record (with Karl in 2010) of being the strongest hurricane ever recorded in the Bay of Campeche," Graves pointed out. Once it hit land, though, Grace quickly dissipated over mainland Mexico, while its remnants later reformed into Tropical Storm Marty in the Eastern Pacific early Monday morning.

Julio Ripoll, WD4R, at the National Hurricane Center, praised members of the VoIP Hurricane Net for being extremely supportive of WX4NHC at the National Hurricane Center. "They are a vital part of the WX4NHC team and part of our elite group we call 'Hurricane Hams.'"

Ripoll said the NHC and WX4NHC rely heavily on the work of the hurricane nets and appreciate the time and effort that goes into gathering surface reports from stations in the affected areas. "These surface reports are vital to NHC, as they paint a picture of ground level physical conditions in real time," he said. "We all work as a team with a common goal to help NHC, which will help those in the affected areas and hopefully help save lives."

NHC Senior Hurricane Specialist Stacy Stewart singled out the VoIP Hurricane Net and the HWN for praise, calling the amateur radio reports "extremely helpful." Read an expanded version.

David Minster, NA2AA; Director of Membership, Marketing, and Communications Kathleen Callahan, KC1MBY, and Product Development Manager Bob Inderbitzen, NQ1R. Also on hand at the ARRL booth were many Southeastern Division officials, Section Managers, and Field Organization volunteers.

The convention, held annually at the Von Braun Center in Huntsville, had to be canceled in 2020 due to the COVID-19 pandemic. "For many of us, this was our return to a large in-person convention after nearly 18 months," Inderbitzen said. "The crowds were big, but the organizers had spread out the exhibits and widened the aisles, allowing for plenty of physical distancing. It was nice to have eyeballs on so many members and friends I've missed seeing."

Amateur Radio on the International Space Station (ARISS) team members at Huntsville included (L - R) ARISS Chairman and ARISS-USA Executive Director Frank Bauer, KA3HDO; ARISS-USA Director of Education Kathy Lamont, KM4TAY, and Dave Jordan, AA4KN, for ARISS Public Relations.

ARRL author Glen Popiel, KW5GP, presented a forum on the Arduino and various ham radio applications using this microprocessor prototyping platform. Popiel's recent book, More Arduino for Ham Radio, is now available from ARRL and its dealers. Other forums included an update from principals for Amateur Radio on the International Space Station (ARISS), an ARRL Membership Town Hall, and an opportunity to hear from ARRL Alabama Section leaders regarding key areas of volunteer activity, including the Amateur Radio Emergency Service®.

Volunteers from the North Alabama DX Club (NADXC) hosted a sold-out banquet on Saturday night that included a presentation from DXpeditioner Adrian Ciuperca, KO8SCA. He shared stories and photos from his 2019 DXpedition to Bhutan, where he operated as A50BOC, A50BPC, and A5B. Just ahead on his travel agenda, Ciuperca will be a member of DXpedition teams to Swains Island and Bouvet Island in 2022. NADXC members were also on hand throughout the convention to help check applications for DXCC and other ARRL Awards.

A Youth Lounge at the Convention included opportunities for young hams and future hams to listen and get on the air. There were also demonstrations of robotics, 3D printing, and activities that included a radio direction-finding foxhunt and kit building.

ARRL CEO David Minster, NA2AA, and ARRL Instructional Designer Steve Goodgame, K5ATA, organized a YouTube Meet Up with many content producers for popular ham radio-themed YouTube channels -- an opportunity to thank the community for its part in nurturing active radio amateurs with information and learning.

ARRL has produced a YouTube video chronicling the convention.

Newspaper Article Boosts Interest in Net Aimed at Visually Impaired, Disabled Amateurs

In June, Gerald Gaule, KE7GGV, of Vancouver, Washington, announced that he was launching a new net in the Portland, Oregon/Vancouver, Washington Metro Area for the visually impaired, blind, and disabled. The net runs on the fourth Sunday of each month at 8 PM Pacific Time on the W7RAT repeater on 440.400 MHz. Some publicity about Gaule and the net in The Columbian, a regional newspaper, has boosted attendance, Gaule said, as well as a request for help.

"Within a few minutes after the article came out, a mom approached me about helping her son, who is visually impaired and autistic, and interested in becoming a ham," Gaule said. "I am planning to help him every step of the way, even becoming a mentor after he gets his license." Gaule said that ARRL Western Washington Section Manager Monte Simpson, W7FF, was providing material and working to come up with a plan involving the 25-year-old's parents that would help get him licensed.

"He's a very nice young man and very confident in himself," said Gaule. "We had a 2-hour meeting yesterday at a local coffee shop. I've offered my help to read the material and get him the right sources to get him on the way to becoming a successful amateur radio operator."

Earlier this year, Simpson appointed Gaule as an Assistant Section Manager for Inclusivity.

As a result of the newspaper article, Gaule reports receiving more than 50 calls from amateur radio operators, as well as people who are interested in amateur radio. He's also gotten more than 100 emails about the story -- all positive.

As the newspaper article explained, "Gaule, who was disabled in 2007, said he worked for commercial radio stations for many years and has been a ham operator for about 20 years. He decided a few months ago to try to include more blind and disabled people in ham radio because it is versatile, educational, and entertaining."

Gaule serves as the Public Information Officer for Region 4 ARES/RACES in Western Washington.

The K7RA Solar Update

Tad Cook, K7RA, Seattle, reports: Sun watchers saw no days without sunspots this week. Average daily sunspot numbers rose from 17.7 last week to 21.7 over the August 19 - 25 reporting week. Average daily solar flux increased from 73.8 to 78.5.

Geomagnetic indicators were quiet, with average daily planetary A index declining from 6.1 to 4.7, and average daily middle latitude A index dropping from 7.6 to 5.7.

We are less than 1 month away from the autumnal equinox in the Northern Hemisphere on Wednesday, September 22. That's when both hemispheres will be bathed in equal measures of solar radiation -- always good for HF propagation.

Predicted solar flux is 84 on August 26 - 27; 85 on August 28 - September 1; 78 on September 2; 73 on September 3 - 11; 74 on September 12 - 15; 76 on September 16 - 18; 77 on September 19 - 20; 76 on September 21, and 75 on September 22 - 29.

Predicted planetary A index is 15, 18, 12, 10, and 8 on August 26 - 30; 5 on August 31 - September 2; 12 on September 3; 5 on September 4 - 10; 10 and 8 on September 11 - 12; 5 on September 13 - 18; 8 on September 19 - 20; 15 and 10 on September 21 - 22; 7 on September 23 - 24; 5 on September 25 - 28, and 8 and 12 on September 29 - 30.

Sunspot numbers for August 19 - 25 were 25, 14, 25, 16, 14, 29, and 29, with a mean of 21.7. The 10.7-centimeter flux was 74.9, 77.7, 77.1, 77.1, 78.1, 80.9, and 83.6, with a mean of 78.5. Estimated planetary A indices were 4, 5, 3, 3, 4, 5, and 9, with a mean of 4.7. Middle latitude A index was 5, 6, 4, 4, 8, 5, and 8, with a mean of 5.7.

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 this Propagation Page.

A propagation bulletin archive is available. For customizable propagation charts, visit the VOACAP Online for Ham Radio website.
