ARES Volunteers Respond to Severe Weather
Weather gone wild might be an apt description of the conditions in many
parts of the US, with sub-freezing temperatures, snow, and ice in areas
not prepared for those sorts of thing. Aberrant weather is happening
across many US regions, causing power and telecommunication outages.
The National Weather Service (NWS) advised at mid-week, "Over 100
million Americans are under Winter Storm Warnings, Winter Storm
Watches, or Winter Weather visories as another round of impactful
winter weather tracks from the Southern Plains to the East Coast,"
adding that a developing winter storm is expected to produce heavy snow
and treacherous ice accumulations from the South Central US to the
Mid-Atlantic.
ARRL Amateur Radio Emergency Service (ARES) volunteers in southern
Texas have been called up by served agencies to help fill the resulting
communication gap. ARRL Emergency Response Director Paul Gilbert,
KE5ZW, who lives in the Austin, Texas, area, reports that ARES members
"have been very, very, very busy" with storm-related traffic. "The
Williamson County ARES team has been activated by the Williamson County
Emergency Manager," he reported earlier in the week.
A net to address power outages, vehicle accidents, health and welfare,
power outages, and weather updates was running around the clock. Two
repeaters in Gilbert's area are down due to power and generator
outages, he said. Electrical power in his area has been up and down,
but his cell service has mostly been working.
Gilbert reported 4 - 8 inches of snow on the ground and "lots of ice,"
with temperatures dipping into record-setting single digits. "The roads
are very treacherous, and emergency services have not been able to
respond to all calls as a result," he said.
Volunteers with Williamson County ARES (Wilco ARES) were able to help
one ham who had no heat, a car out of gas, and 18ø F in the house to
find shelter for him and his dog.
The ARES net is tracking the rolling blackouts as the local provider
grid becomes overwhelmed by increased demand. "Some water shortages
were reported, as pumping stations failed from lack of power," he said.
Elsewhere, North Texas SEC Greg Evans, K5GTX, reported that the Grayson
County ARES team has activated to staff warming shelters, and the
emergency operations center (EOC) in Hill County was activated on
February 15.
New Mexico Section Emergency Coordinator Jay Miller, W5WHN, reports
that southeastern New Mexico is experiencing rolling power blackouts
due to high demand. "The stations checking in via HF and repeaters are
having frozen water pipe problems," Miller said. "Most of the New
Mexico ARES stations have backup power."
Miller said the rest of New Mexico is digging out of three storms'
worth of snow accompanied by frigid temperatures and impassable roads,
especially in the mountains.
Jim Tucker, KB0QNW, reported from southeast New Mexico, "We continue to
experience rolling blackouts. I continue to monitor local and regional
repeaters and systems, as well as the 7290 Traffic Net, should any need
arise. I [passed] a message from Bowie, Texas, to Clovis, New Mexico."

ARRL Board Considers Plan to Cover New $35 FCC Fee for Some Young
Applicants
At its Annual Meeting in January, the ARRL Board of Directors
considered a motion to offer a new service that would pay the new but
not-yet-implemented $35 FCC application fee for a limited number of new
radio amateurs younger than age 18 who, at the time of testing,
belonged to an ARRL-affiliated 501(c)(3) charitable organization and
passed their tests through an ARRL VEC-sponsored exam session. The
proposal called for reducing the VEC fee for these candidates to $5.
The initial proposal came from ARRL Southeastern Division Director
Mickey Baker, N4MB. Other Board members offered subsidiary motions.
Supporters said the purpose behind the motion was to ameliorate the
potential financial hardship the pending FCC application fee posed on
certain minors applying for their first license, and to encourage new
youth membership.
Consideration of the motion, which was subject to considerable
discussion, was deferred to an ad hoc committee composed of the members
of the ministration & Finance Committee, two Members of the Programs
& Services Committee, and ARRL CEO David Minster, NA2AA (or his
designated representative). The Board directed the panel to review and
more fully develop the proposal and report back to the Board by the end
of March with a recommendation as to whether such a program should be
adopted and, if adopted, how it should be implemented.
Supporters expressed the belief that recruitment and training of young
radio amateurs "is a necessary and proper mission of the ARRL" and that
subsidizing the $35 fee "will reduce the number of new amateurs that
otherwise would be lost from these groups."
In December, the FCC agreed with ARRL and other commenters that the
initially proposed $50 fee for certain amateur radio applications was
"too high to account for the minimal staff involvement in these
applications." In a Report and Order (R&O), the FCC scaled the fee back
to $35 for a new license application, a special temporary authority
(STA) request, a rule waiver request, a license renewal application,
and a vanity call sign application. All fees are per application. There
will be no fee for administrative updates, such as a change of mailing
or email address. Read an expanded version.
Innovator Ulrich Rohde, N1UL, Donates Sophisticated Vector Signal
Generator to ARRL
ARRL Life Member Ulrich Rohde, N1UL, has donated a Rohde & Schwarz
SMBV100A vector signal generator to the ARRL Laboratory. The device
offers internal signal generation for all major digital radio
standards. "That is absolutely fabulous news and extremely generous,"
ARRL CEO David Minster, NA2AA, told Rohde.
ARRL Laboratory Manager Ed Hare, W1RFI, said the instrument will be a
valuable addition to the Lab's testing capabilities.
"We will be able to do more comprehensive tests on modern radios,
almost all of which use software-define radio technology," Hare said.
"We will also be able to add testing of receivers' digital capability.
The flexibility of this generator will serve the Laboratory for years
to come."
Hare said he was looking forward to learning more about the SMBV100A
once it's installed at the Lab. "The potential is really exciting," he
said. "As always, we appreciate the support that Ulrich Rohde has given
to the Lab over the past several decades."
Rohde said vector signal generators are the logical successors to the
older AM/FM modulation-capable signal generators and have practically
unlimited capability. "For some of the tests required to characterize a
software-defined radio (SDR), we need different test equipment," he
said. Rohde noted that the SMBV100A has a built-in arbitrary waveform
generator capable of operating up to 6 GHz, with "many complex signals
in it library, and also has the familiar AM/FM simple mode"
Ulrich Rohde, N1UL.
Going from analog to digital SDRs, large-signal behavior is best
determined with special multi-carrier signals, Rohde said. Instead of a
two-tone test signal for, say, measuring IF characteristics, the
SMBV100A can generate up to 30 discrete tones. Rohde said the SMBV100A
can produce any signal "as long as you can describe it mathematically,"
even an FT8 signal. The bottom line is a more realistic test result.
Rohde said that in 1982, while he headed the Department of Defense
Radio Division at RCA, he and his engineering group "invented what is
now called the software-defined radio," which was considered classified
military information at the time.

South Coast ARES Joins South Coast CERT in California Evacuation
Operation
In California, the SC4ARES group, part of the SC4 Amateur Radio Club of
La Honda, Loma Mar, Pescadero, San Gregorio, and South Skyline in the
ARRL Santa Clara Valley Section (south of San Francisco in northern
California), joined with South Coast CERT members in late January. The
groups performed a joint exercise to notify residents in the CZU
Lightning Complex fire areas of mandatory evacuations in front of a
moderate atmospheric river event that had the potential to cause debris
flows in those burn-scarred areas.
Atmospheric rivers are columns of vapor that move with the weather,
carrying an amount of water vapor roughly equivalent to the average
flow of water at the mouth of the Mississippi River. When atmospheric
rivers make landfall, they often release this water vapor in the form
of rain or snow.
Fire Chief Ari Delay of La Honda Volunteer Fire Brigade -- a SC4ARES
served agency -- called together ARES and CERT leaders on January 24 to
evaluate the areas to be evacuated and assess who hadn't already left
the area. Angelo Dragone, N6QAD; Bob Smith, W6RES, and Peter Chupity,
KI6FAO, used Radio Mobile to assess likely relay spots in the
mountainous terrain of the areas of Whitehouse Creek, Gazos Creek,
Butano Creek, Dearborn Park, and Loma Mar. They tested these areas
using UHF as a stand-in for the General Mobile Radio Service (GMRS)
radios that CERT members would be using for the actual exercise.
On January 26, the CERT and SC4ARES members met at Pescadero High
School to deploy teams to warn evacuees and leave literature describing
the nature of the incoming weather. The CERT members communicated with
the ARES team, and the ARES team kept in contact with the temporary
operations center at the high school. In Whitehouse Creek canyon, all
CERT members were also hams, so no GMRS radios were needed. CERT/ARES
participants communicated with KI6FAO, perched on a hilltop to relay to
the operations center.
The operation was a success, and the hourly rainfall rate didn't reach
the threshold to trigger debris flows in any of the areas. -- Thanks to

British Columbia Radio Amateur Copies Signal from Mars-Orbiting
Satellite
As reported on Spaceweather.com, Canadian radio amateur Scott Tilley,
VE7TIL, of Roberts Creek, British Columbia, has snagged another signal
from deep space. His latest conquest has been to copy the signal from
China's Tianwen-1 (pronounced "tee-EN-ven") probe, which went into
orbit around Mars on February 10. Tilley told Spaceweather.com that the
probe's X-band signal was "loud and audible."
"It was a treasure hunt," Tilley told Spaceweather.com. He explained
that while the spacecraft did post its frequency with the International
Telecommunication Union (ITU), it was too vague for precise tuning (X
band is between 8 GHz and 12 GHz).
Launched last July, Tianwen-1 represents China's first Mars mission. It
consists of an orbiter and a rover, which will land on the Martian
surface in May or June 2021. It is able to photograph the planet's
surface while in orbit.
Finding signals from deep space is a sub-hobby for Tilley, who seeks
what he calls "zombie satellites" among other signal sources. In 2020,
he tracked and identified signals from the experimental UHF military
communication satellite LES-5.
In 2018, while hunting for an undisclosed US government spacecraft lost
in a launch mishap, he spotted the signature of IMAGE (Imager for
Magnetopause-to-Aurora Global Exploration), a NASA spacecraft believed
to have died in December 2005.
Tilley has also picked up signals from NASA's Mars Reconnaissance
Orbiter, and the United Arab Emirates Hope probe, both orbiting Mars
some 124 million miles away.
He uses a homemade 60-centimeter dish and relies on software-defined
radios (SDRs) to accomplish the task.
Radio amateurs have been listening for signals from space since the
1957 launch of Sputnik 1, which transmitted at around 20 MHz. Read an
expanded version.

Fatten Your DXCC Total in the ARRL International DX Contest (CW) This
Weekend
It's the US and Canada against the world in the 2021 ARRL International
DX Contest (CW), which takes place this weekend, February 20 - 21. Join
thousands of amateurs worldwide as they compete in this exciting
international event.
Whether you're a casual operator just looking for DX contacts, an
awards chaser, or working on your DXCC, this contest offers something
for everyone.
US and Canadian operators work as many DX stations in as many DXCC
entities as possible on 160, 80, 40, 20, 15, and 10 meters. DX stations
work as many US and Canadian stations in as many of the 48 contiguous
states and provinces as possible. This means the DX will be looking for
you!
For 2021, ARRL has issued temporary accommodations for multioperator
stations in the contest, allowing them to adhere to local social
distancing guidelines. This will open the door for many DX operators to
participate in the contest while keeping their team members safe.
Visit the ARRL Contests web page for rules and complete details.

Former ARRL Southwestern Division Director Art Goddard, W6XD, SK
Former ARRL Southwestern Division Director Art Goddard, W6XD, of Costa
Mesa, California, died on February 13. An ARRL Life Member, he was 78.
First licensed in 1956, Goddard was an electrical engineering graduate
of Worcester Polytechnic Institute and Montana State University. He
worked for Collins Radio and later for Boeing, from which he retired as
an executive.
After several years working with local governments in southern
California on proposed antenna ordinances, he was elected ARRL
Southwestern Division Vice Director in 1995, serving two terms before
being elected Director in 2001. After retiring from the ARRL Board, he
continued to follow ARRL affairs and advocate for stronger public
relations on behalf of amateur radio.
Goddard was active on the air from HF through microwaves. A member of
the Southern California Contest Club, he took part in contest
DXpeditions to locations ranging from subarctic to tropical, operating
the CQ World Wide DX Contest in 26 of the 40 CQ zones. He also headed
teams of VHF/UHF/microwave contest rovers.
Goddard was heavily involved with the Costa Mesa Historical Society and
was co-author of two books on Costa Mesa history.
-------------------------------------------------------------------
The K7RA Solar Update
Tad Cook, K7RA, Seattle, reports: This stretch of days with zero
sunspots has continued for 2 weeks now. Wednesday evening, though,
while viewing the STEREO spacecraft image, I saw a very bright spot on
the sun's northeast horizon. Spaceweather.com reported, "A new active
region is hiding just behind the sun's northeastern limb. It might be a
sunspot."
Average daily solar flux dipped from 72.8 to 72 this week. Average
daily planetary A index was unchanged from last week at 7.7.
Cracks reported on Tuesday in Earth's magnetic field allowed solar wind
to pour in, sparking aurora around the Arctic Circle. Alaska's College
A index jumped to 45, after the K index hit 7 at 0600 and 0900 UTC.
This is from a single magnetometer near Fairbanks, Alaska.
Predicted solar flux for the next 30 days is 72 on February 18 - 25;
74, 73, and 74 on February 26 - 28; 73, 74, and 74 on March 1 - 3; 73
on March 4 - 6; 74, 70, and 74 on March 7 - 9; 76, 72, and 71 on March
10 - 12, and 72 on March 13 - 19. Flux values may rise to 76 again on
March 23 - 24.
Predicted planetary A index is 5 on February 18 - 19; 16, 12, 8, and 8
on February 20 - 23; 5 on February 24 - 28; 18, 15, and 8 on March 1 -
3; 5 on March 4 - 5; 15 on March 6; 5 on March 7 - 11; 18, 10, 8, and 8
on March 12 - 15, and 5 on March 16 - 19.
Sunspot numbers for February 11 through 17 were 0, 0, 0, 0, 0, 0, and
0, with a mean of 0. The 10.7-centimeter flux was 75.8, 72.1, 71.3,
71.4, 69.6, 71.5, and 72.4, with a mean of 72. Estimated planetary A
indices were 4, 5, 13, 4, 5, 15, and 8, with a mean of 7.7. Middle
latitude A index was 2, 4, 10, 3, 3, 11, and 6, with a mean of 5.6.
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...,"

In Brief...
The latest issue of the free publication ITU News Magazine highlights
World Radio Day (observed each year on February 13). The issue features
two articles on amateur radio. Articles in the magazine include the
evolution of radio throughout the ages, ham radio and emergency
communications, and remarks by International Amateur Radio Union (IARU)
President Tim Ellam, VE6SH, regarding why World Amateur Radio Day
(celebrated each year on April 18) is important to highlight crucial
services.
Ham Radio in Friedrichshafen, Germany, is tentatively on for 2021. The
show was canceled last year because of the pandemic. Organizers for
Europe's International Amateur Radio Exhibition this week expressed
optimism that the 45th Ham Radio, sponsored by the Deutscher Amateur
Radio Club (DARC), will be able to take place June 25 - 27. "We are
watching the situation closely, of course," a message from
Friedrichshafen Fairgrounds CEO Klaus Wellmann said. "At the moment, we
are assuming that we will be able to hold Ham Radio in accordance with
an extensive, tried-and-proven safety and hygiene concept and are
looking forward to seeing everyone again at Europe's most important
trade fair for amateur radio."
The former president of Argentina, Carlos Menem, ex-LU1SM, died on
February 14. He was 90. Menem took office in 1989, serving for 10
years. Menem was active on the air in the 1980s and 1990s. He had
earlier served as regional governor. Menem served as a senator from
2005 until 2019. According to the New York Times, "Menem was
hospitalized in December with kidney failure and had been put in a
medically induced coma."
Getting It Right
The story "ARRL Board Confers Awards on Skip Jackson, KS0J, and Josh
Nass, KI6NAZ," in the February 4 edition of The ARRL Letter includes
incorrect information. The recipient of the Knight Award receives a
plaque. The recipient of the Leonard Award receives a plaque and a $250
contribution to a charity designated by the recipient.
