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^(R) 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^(R) 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 T£xpam, 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.'"

Charlestown, Rhode Island, were
toppled around southern New England
as a result of Henri. [Courtesy of
Mike Lill, WD1N]
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.

Huntsville Hamfest Hosts 2021 ARRL Southeastern Division Convention
The annual Huntsville Hamfest, held on August 21 - 22, served as host
for the 2021 ARRL Southeastern Division Convention. Convention visitors
were able to meet with many ARRL officials and staff, including
President Rick Roderick, K5UR; Chief Executive Officer
2021 Alan G. Thorpe, K1TMW, Memorial
Scholarship winner Kaleb Ruddle,
KN4JGJ, of Lawrenceburg, Tennessee
(L), with ARRL President Rick
Roderick, K5UR, at the 2021 ARRL
Southeastern Division Convention.

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. [Bob Inderbitzen, NQ1R,

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^(R).
Volunteers from the North Alabama DX Club (NADXC) hosted a sold-out
banquet on Saturday night that included a presentation from
DXpeditioner rian 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.
ARRL members Barbara Shafer, KE5QAT,
and Steve Shafer, WA7RC, of Slidell,
Louisiana, were among the visitors
to the ARRL booth at the ARRL
Southeastern Division Convention in
Huntsville. [Bob Inderbitzen, NQ1R,

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.

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.
