Contest University Celebrates 100 Years of Yagis
The Yagi-Uda beam antenna was invented 100 years ago, in 1926, and
Contest University (CTU) is celebrating its centennial with a live Zoom
webinar this Saturday, September 19, 2026, at 1600 UTC (noon Eastern).
The free webinar, titled The Yagi Turns 100, will be presented by Greg
Ordy, W8WWV, and will be available online at w3lif.org/yagi. Ordy will
walk through the history of this amazing antenna that has been a
mainstay of amateur radio DXing and contesting for a century.
There is no pre-registration for this event.
Click on the link (above) before 1600 Zulu on Saturday to watch.
Contest University Chairman Tim Duffy, K3LR, and Scott Jones, N3RA, will
be monitoring the chat during the presentation and will relay questions
from viewers to Ordy at the conclusion of his talk.
Duffy says the webinar will be recorded, and the recorded link will be
posted on the CTU website
next week.
WRTC 2026 Organizers Honored by FOC
The First Class CW Operators Club (FOC) has awarded its highest honor,
the Al Slater, G3FXB (SK), Memorial Award, to the World Radiosport Team
Championship 2026 (WRTC 2026) Organizing Committee in recognition of its
work not only in planning and executing last Julys competition, but also
in its response to allegations of cheating by some participants.
FOC President John Warburton, G4IRN, said the award recognizes an
individual, group, or organization whose contribution to amateur radio
reflects the qualities that Al embodied throughout his life: operating
excellence, friendship, encouragement of others, and service to the
hobby.
According to a report in The Daily DX, Warburton said FOC determined
that the WRTC committee demonstrated those qualities on an exceptional
scale, [creating] an environment that showcases the very highest
standards of amateur radio operating, rewarding skill, fairness,
technical competence, and ethical conduct. He added that the judging
committees careful verification work ensured that these standards were
upheld and that the results reflected the true performance of those who
competed within the rules. This was a reference to the Organizing
Committees recent announcement that several stations, including the
original winner, had been disqualified due to rule violations discovered
after the contest.
The award was presented at FOCs annual gala dinner on September 12 in
Cheshire, England.
Get Ready for Jamboree on the Air
We've got scouts, we've got a special event call sign, and we'd love as
many hams as possible near and far to come find us on the air. Thats
how Sal Mancuso, W6SAL, is promoting Jamboree on the Air (JOTA) 2026 on
behalf of the Silicon Valley Monterey Bay Council of Scouting America
(formerly Boy Scouts of America). JOTA is an annual worldwide event, on
the air and on the internet (as JOTI), with the goal of promoting
friendship and global citizenship via amateur radio and the internet.
This years event will be held from October 16-18, and now is a good time
for radio clubs and individual hams to reach out to local scout units to
set up JOTA experiences.
For Mancuso, it has meant getting a special event call sign K6S and
setting up a public demonstration station on October 17 for scouts from
throughout the Silicon Valley Monterey Bay Council. The council serves
10,000 youth across Monterey, San Benito, Santa Clara, and Santa Cruz
counties in California. We'll have approximately seven licensed
operators of varying license classes (Technician through Extra) on hand,
running HF, VHF, and UHF simultaneously, all signing K6S, explains
Mancuso. Scouts will be hands-on at the mic and keyboard the whole time
this is their event, not just something they're watching ... We'll be
active on HF SSB and FT8, with packet possible as well. Planned HF SSB
frequencies are 7.090, 14.290, 18.140, and 28.990 MHz, but Mancuso noted
that We'll also be posting our actual live frequencies on Spotted Hams
as the day goes, since real-world band conditions may shift our plan a
bit.
More information on setting up a JOTA/JOTI operation may be found at
www.jotajoti.info. ARRL has resources to assist volunteers who are
working with scouts, including a flyer promoting Radio Communications
for Scouts
(PDF) and the ARRL Radio and Wireless Technology Patch Program. For
additional ideas, visit www.arrl.org/amateur-radio-and-scouting.
AMSAT Youth Initiative Course
An online course titled Satellites and Astronomy is now available as
part of the AMSAT Youth Initiative programs Satellites in Space Help Us
Live a Better Life on Earth series. This is the fifth course in the
series, produced by AMSAT, the Radio Amateur Satellite Corporation, and
posted on its youth-focused website, buzzsat.com. AMSAT says the goal of
BuzzSat is to encourage youth to pursue careers in aerospace and
communications by studying science, technology, engineering, art, and
math (STEAM). Other courses in the series include An Introduction to
Satellite Meteorology, Satellites and Climate Change, Satellites and
Pollution Control, and Satellites and Natural Resources.

ARRL Live Events and Podcasts
On the Air LIVE
Join ARRL Director for Learning and Education Wayne Greene, KB4DSF, for
the September episode of OTA Live on Tuesday, September 22 at 8 PM
Eastern, where he will explore an inexpensive and practical way to
evaluate the performance of your handheld (HT) radio. Using a low-cost
Software Defined Radio (SDR) dongle, free SDR software, and free audio-
editing software, Wayne will demonstrate several tests that can help you
get a better idea of how well your HT is working. While these
measurements wont replace lab-grade testing, they can reveal useful
information about your radios performance. Wayne will also demonstrate
how to use these tools to identify CTCSS tones and DCS codes. The
livestream will air on the ARRL's learning center, learn.arrl.org.
Preregistration is required and can be accomplished through the Learning
Center.

About the New QST Product Review Comparison Tool for ARRL Lab-Tested
Devices
Some of the products seen in QST Product Review, including transceivers,
receivers, and amplifiers, are tested in the ARRL Lab to see how they
stack up against the manufacturers claims. Those test results are
included in the published review to help you make more informed buying
choices. ARRLs new online interactive Comparison Tool
for ARRL Lab-Tested Devices makes it even easier to refer to, compare,
and understand the test results. ARRL Digital RF Engineer John Jobin
McAuliffe, W1DRF, visits the podcast to talk about what the tool does
and how to use it to better inform your radio purchases. More info

The ARRL Solar Report

Prediction Center]
Solar image on September 17, 2026 [Photo courtesy NOAA Space Weather
Prediction Center]
Solar flare activity is expected to remain at very low levels, with a
chance for isolated C-class flares through September 19, according to
NOAAs Space Weather Prediction Center (SWPC). Solar wind speed was
steady near 530 km/s, and negative polarity CH HSS (coronal hole high-
speed stream) effects are anticipated to persist through September 18,
with additional enhancements likely today due to flanking influences
from CMEs (coronal mass ejections) that departed the Sun on September 13
and 14. Geomagnetic activity is expected to reach active to G1 (minor)
storm levels today due to combined CH and CME influences.
Unsettled to active conditions are likely on September 18-19 as
enhancements wane.
The Australian Space Weather Forecasting Centre reports that there are
currently three numbered sunspot regions on the solar disk, and that all
three are stable.
No flares are expected over the next several days.
The global HF propagation forecast for middle latitudes is normal to
fair today, followed by normal propagation in the days that follow.
Predicted 10.7-centimeter radio flux from the SWPC: Sep 17, 93; Sep
18-19, 90; Sep 20, 95; Sep 21, 100; Sep 22, 110; Sep 23, 105.
Send your tips, questions, or comments to w2vu@arrl.org.

the ARRL Technical Information Service, read
"What the Numbers Mean...," and check out
the Propagation Page of Carl Luetzelschwab, K9LA.

is available. For customizable propagation charts, visit the VOACAP
