Prominent Radio Amateur Helps to Lead US Convalescent Plasma COVID-19
Expanded Access Study
Well-known contester, DXer, and National Contest Journal (NCJ) Editor
Scott Wright, K0MD, has been "substantially" stepping back from ham
radio while offering his expertise to the US convalescent plasma
COVID-19 Expanded Access Program. The study began in early April under
the leadership of Principal Investigator Dr. Michael Joyner, MD, of the
Mayo Clinic; Dr. Peter Marks, MD, PhD -- who is AB3XC -- and Dr. Nicole
Verdun, MD, of the US Food and Drug ministration; Dr. Arturo
Casavedall, MD, PhD, of Johns Hopkins University, and Wright, who is
with the Mayo Clinic.
"The US Convalescent Plasma Expanded Access Program is a collaborative
project between the US government and the Mayo Clinic to provide access
to convalescent plasma for patients in the US who are hospitalized with
COVID 19," Wright told ARRL. The work has been referenced during White
House press briefings and in congressional testimony. The US
government-supported study collects and provides blood plasma recovered
from COVID-19 patients, which contains antibodies that may help fight
the disease. The Mayo Clinic is the lead institution for the program.
"My role was to organize the infrastructure and the research approach,
and to help lead the set-up of the data collection and of the website
teams, while overseeing the study conduct and regulatory compliance,"
Wright explained.
According to a June 18 Washington Post article, "A large study of
20,000 hospitalized COVID-19 patients who received transfusions of
blood plasma from people who recovered found the treatment was safe and
suggests giving it to people early in the disease may be beneficial."
An initial safety report on 5,000 patients appeared in May in the
Journal of Clinical Investigation. The safety study on 20,000 subjects
referenced in the Washington Post article was published earlier this
month in the Mayo Clinic Proceedings.
Wright said most scientific studies of this magnitude take months to a
year with planning and execution to get under way. In this case, the
study team went from zero to 60 in a few short weeks.
"We started in less than a week. Most studies recruit 2,500 - 5,000
patients," Wright said. "We have recruited over 30,000 patients in 10
weeks, exceeding all expectations."
Hospitals in all 50 states and several US territories are
participating, Wright said, and more than 8,000 physician-scientists
are working with the team as investigators at their hospitals. "We also
helped manage the start-up of collection of convalescent plasma by the
large blood organizations, such as the American Red Cross, by
strategically connecting donor pools and people willing to donate with
the blood collection centers."
Wright's study responsibilities, which are on top of his regular day
job, have required him to work daily, including weekends, for all of
April, most of May, and all of June. "It has been intense," he said.
Wright said an FDA announcement on the benefit of convalescent plasma
was expected soon. The FDA has been inviting donations of convalescent
plasma from individuals who have fully recovered from COVID-19.
Wright will be the keynote speaker at the QSO Today Virtual Ham Expo
August 8 - 9 to discuss the study, its results, and, he said, "linking
it to skills acquired through ham radio. Read more.
IARU Appoints New Electromagnetic Compatibility (EMC) Coordinator
The International Amateur Radio Union (IARU) ministrative Council has
appointed Martin Sach, G8KDF, as global Electromagnetic Compatibility
(EMC) Coordinator, succeeding Tore Worren, LA9QL.
"EMC is a major challenge for all radiocommunication services," the
IARU noted. "Radio amateurs are experiencing increased interference
caused by unwanted radio frequency emissions from a wide variety, and
rapidly growing number, of electronic devices."
The EMC Coordinator's mission is to ensure that the concerns and needs
of radio amateurs are effectively addressed in international standards
bodies -- particularly the International Special Committee on Radio
Interference (CISPR) and the International Telecommunication Union
(ITU) -- as well as in regional telecommunication organizations and at
national levels through IARU member-societies. Assisting in the effort
is a network of volunteers with expertise in the field of EMC.
IARU President Tim Ellam, VE6SH, said, "The IARU ministrative Council
is grateful for Tore's leadership and for his willingness to continue
contributing to this vital work. We are fortunate that someone as
qualified as Martin is willing to take the reins. He has already
represented the IARU effectively at important international meetings
and we look forward to working even more closely with him."
Radio amateurs throughout the world support the work of the IARU
through membership and involvement in their national IARU
member-societies. The IARU needs qualified volunteers in this and other
fields.
New IARU Video
The video "What is IARU?" is now available on the International Amateur
Radio Union (IARU) Region 2 website.
"This video explains the mission and roles of IARU to represent,
develop, and defend frequencies for amateur radio around the world,"
IARU Region 2 explains. "It also describes the regional organizations
and the critical roles of its more than 160 member-societies." The
English-language presentation was developed by the IARU ministrative
Committee and approved at its meeting last October in Lima, Peru.
The short video, available in English and Spanish, was produced by IARU
Region 2 Director Carlos Beviglia, LU1BCE, and Fernando Gomez Rojas,
LU1ARG. The videos are available in MP4 format.
IARU Region 2 encourages member-societies and radio clubs to use the
videos to explain the role and mission of IARU to amateurs, regulators,
and others.
Researchers Use 200 Years of Sunspot Observations to Create "Sun Clock"
Researchers in the UK and the US have developed a new "sun clock" that
quantifies extreme space weather and pinpoints distinct on/off times of
high solar activity and space weather. The sun clock will assist in
planning to protect space and ground-based infrastructure that is
sensitive to space weather. The study, "Quantifying the solar cycle
modulation of extreme space weather," was published in Geophysical
Research Letters. It explains that the sun clock uses the daily sunspot
number record available since 1818 to map solar activity over 18 solar
cycles to a standardized 11-year cycle or "clock."
"Extreme space weather events can significantly impact systems such as
satellites, communications systems, power distribution, and aviation,"
a Warwick University news release said, noting that these events are
driven by solar activity. "By devising a new, regular 'sun

clock', researchers have found that the switch on-and-off of periods of
high solar activity is quite sharp."
The researchers' analysis shows that while extreme events can happen at
any time, they are much less likely to occur during quiet intervals.
The sun clock is aimed at helping scientists to determine more
precisely when the risk for solar storms is highest and to plan the
impact of space weather on space infrastructure. This gains importance
as Solar Cycle 25 is imminent.
According to the researchers, no two solar cycles are the same, but
using a mathematical technique known as the Hilbert transform, they
were able to standardize the solar cycle for the first time. The clock
revealed sharp transitions between quiet and active periods of solar
activity.
"Once the clock is constructed from sunspot observations, it can be
used to order observations of solar activity and space weather," the
university said. This includes the occurrence of solar flares and the
10.7-centimeter solar flux that tracks solar coronal activity.
The researchers determined that once past on/off times are obtained
from the clock, the occurrence rate of extreme events when the sun is
active or quiet can be calculated.
"Scientists spend their lives trying to read the book of nature," lead
author and Professor Sandra Chapman of the University of Warwick's
Centre for Fusion, Space, and Astrophysics, said. "Sometimes, we create
a new way to transform the data, and what appeared to be messy and
complicated is suddenly beautifully simple."

ARRL Illinois Section Has a New Section Manager
Thomas Beebe, W9RY, has been appointed as the Illinois Section Manager,
effective July 1. He succeeds Ron Morgan, AD9I, who stepped down due to
health concerns that became apparent just as he was ready to start a
new term. Morgan was re-elected in the spring Section Manager election
cycle and had served as SM since February 2017. Beebe, who lives in
Marion, will fulfill the 2-year term that extends through June 30,
2022.
Beebe was one of three candidates who ran for the post in the spring SM
election. He has served as an Assistant Section Manager, Official
Emergency Station, and a Field Instructor and Field Examiner. Beebe has
been a ham for more than 50 years.
ARRL Radiosport and Field Services Manager Bart Jahnke, W9JJ, made the
appointment after consulting with ARRL Central Division Director Kermit
Carlson, W9XA.
MARS Announces HF Skills Exercise
Members of the Military Auxiliary Radio System (MARS) will conduct an
HF skills exercise July 20 - 24 to hone their operating skills and
messaging-handling capabilities. MARS members will be reaching out to
the amateur radio community via the 60 meters Channel 1 Net (5330.5 kHz
dial) twice a day, the SATERN HF net (14.265 MHz), and by contacting
various stations via HFLink throughout the exercise.
Participating MARS members will be requesting assistance with
collecting county status information as well as airport weather
information, called METARs. MARS members will also be passing ICS 213
messages to numerous Department of Defense (DoD), federal, and amateur
radio addressees.
This exercise will be announced via WWV at 00:10 and via WWVH at 00:50
starting on or about July 13. WWV and WWVH listeners will be asked to
take an online listener survey. This HF radio training event will not
impact regular communications.
A Department of Defense program, MARS organizes and trains amateur
radio volunteers to operate in military radio networks to support HF
radio contingency communications. Among other missions, MARS provides
communication support to civil authorities and assists in establishing
normal communication under emergency conditions. -- Thanks to Paul
English, Chief, Army MARS
The K7RA Solar Update
Tad Cook, K7RA, Seattle, reports: No sunspots this week.
Spaceweather.com reported a couple of weak, barely emerging spots
(never numbered) but, judging by their magnetic polarity, were from new
Solar Cycle 25. We rely on NOAA for official sunspot numbers, and the
most recent one reported was 11 on June 15.
Average daily solar flux over the June 25 - July 1 reporting week
averaged 68.6, up from 67.7 over the previous 7 days. The average daily
planetary A and the average middle latitude A indices both were 5.5.
Predicted solar flux over the next 45 days is 68 each day from July 2
until August 15 -- hardly a promising outlook. Even with no sunspots,
it would be nice to see solar flux values north of 70.
The predicted planetary A index is 5 on July 2 - 26; 8 on July 27 - 28;
5 on July 29 - August 1; 8 on August 2 - 3, and 5 on August 4 -15.
Sunspot numbers for June 25 - July 1 were 0, 0, 0, 0, 0, 0, and 0, with
a mean of 0. The 10.7-centimeter flux was 68.9, 67.8, 68.9, 69.2, 68.7,
68.1, and 68.9, with a mean of 68.6. Estimated planetary A indices were
3, 6, 7, 4, 3, 4, and 6, with a mean of 5.5. Middle latitude A index
was 2, 6, 6, 4, 4, 5, and 6, with a mean of 5.5.
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...,"
