Get On the Air for the ARRL International DX Contest

[http://www.arrl.org/arrl-dx/]


We're seeing peak conditions from Solar Cycle 25 just in time for the ARRL
International DX SSB Contest. It gets underway this weekend at 0000 UTC on
Saturday, March 1, and concludes at 2359 UTC on Sunday, March 2.


ARRL Contest Program Manager Paul Bourque, N1SFE, is gearing up to operate as
part of a multi-operator, single-transmitter station for the event. He is
eager to get started. "This is a great contest to work some new DX and to add
to your DXCC totals, as DX stations will be pointing their antennas towards
the US and Canada this weekend," he said.


The contest is an exercise in endurance, but also a great primer on DX
propagation. Earlier in the month, the CW portion of the contest garnered at
least 4,830 log submissions.


The nature of the contest means the whole world is trying to work North
America. "Even modest stations can experience the thrill of working some new
countries," said Bourque. "Just get on the air!"


If a full weekend of contesting sounds too overwhelming, ARRL encourages
radio amateurs to set a small goal - perhaps 100 contacts to start. Get into
the groove of it and start stretching the goal. Maybe you'll wind up at 100
multipliers instead. Since each of those multipliers is a DX entity those
100, if confirmed with a QSL, could equip the operator with the necessary
contacts to apply for an ARRL DXCC(R) Award.


With band conditions expected to be good, and activity expected to reflect
that excitement, Bourque hopes to receive even more log submissions. "The
more, the merrier. We really hope hams will take advantage of this prime
operating opportunity."

ARRL's "On the Air Live" Continues to Grow

[http://learn.arrl.org]


ARRL is equipping the next generation of radio amateurs with the knowledge to
get active on the air. "On the Air Live" is a monthly interactive webinar
series that does deep-dives into topics aimed at the new and intermediate
ham. It complements material found in On the Air magazine. February's event
had nearly 130 people in attendance.

 
The events are hosted by ARRL Education Specialist Wayne Greene, KB4SDF. "OTA
Live" has seen rapid growth and good engagement in the two months it has been
going. "The most recent �-�On the Air Live' covered programming a handheld
radio, and we got a lot of good questions," said Greene. "Being an
interactive webinar, we have the opportunity to spend time discussing things
on which members need more information."


"On the Air Live" is accessed through the ARRL Learning Center at
learn.arrl.org [ http://learn.arrl.org ] . It is a benefit of ARRL
membership, and members must be logged into the web site to access it for
live or archived sessions.

 
The next "On the Air Live" is Tuesday, March 25, 2025, at 8:00 PM Eastern. It
will focus on advanced functions of handheld radios, including getting them
on digital modes. "We're going to take the handheld radio and expand its
capability by attaching it to a soundcard," said Greene. Those who attend
will learn how to use APRS and VARA (including Winlink).

 
"We had a great time with members on the last one, and I hope more people
will join us in March," said Greene.

Colorado High School Students Visit the Plishner Radio Astronomy and Space
Sciences Center


In late January 2025, 17 students and staff members from Las Animas High
School (LAHS) in Colorado visited the Deep Space Exploration Society Radio
Telescope [ https://dses.science/ ] (DSES) located at the Plishner Radio
Astronomy and Space Sciences Center near Haswell, Colorado. They also got an
introduction to amateur radio.


[https://dses.science/]


"This first field trip visit of high school students reflected the dreams of
Michael Lowe, former DSES board president, who sought to create a center for
radio astronomy and space science education in southeast Colorado," said DSES
President Myron Babcock, KL7YY. Since 2009, society members have devoted
hundreds of hours to rebuilding the Plishner site. In 2024, a grant from
Amateur Radio Digital Communications (ARDC) provided funds to complete a new
building suitable for hosting groups.

 
DSES board member Ray Uberecken, AA0L, and DSES member Roger Oakey, W3MIX,
showed students how the big dish was controlled to track and focus on deep
space objects as Earth revolves. DSES Vice President Bill Miller, KC0FHN,
gave an overview of the organization's history and the years of effort
required to revive the 60-foot-diameter radio telescope. He introduced radio
astronomy and some of the studies DSES members have conducted since restoring
the telescope, including detecting pulsars and masers, observing solar and
planetary radio emissions, and mapping the hydrogen line to show which
galaxies are moving toward or away from Earth.

 
Students braved intense winds and cold to venture to the underground bunker
location of the DSES amateur radio station, K0PRT. Board member Paul Sobon,
NO0T, demonstrated how long-distance contacts are made using high-frequency
(HF) transceivers. Under his supervision, several students learned to call
CQ. Unfortunately, because band conditions were poor, no student got a
response. Later, Sobon was able contact a radio amateur in the Canary
Islands, and students observed two-way HF radio communication between
stations over 5,000 miles apart.

 
About half the students who visited the site will participate in this year's
Colorado Science Olympiad competition. Jennifer Pointon, Science Olympiad
coach and LAHS counselor, said she wanted students to see the Plishner
facilities and learn how DSES can provide opportunities for research and
mentorship in astronomy, radio, electronics, and engineering.

 
The Deep Space Exploration Society is an all-volunteer group united by love
for science, exploration, and learning about space. Its members include
engineers (software, radio, electrical), professors, pilots, business owners,
military veterans, construction workers, truck drivers, and amateur radio
operators. DSES welcomes new members. Student membership is free.

In Brief...

How about some Pi with that ham radio? The David Sarnoff Radio Club [
https://n2re.org/ ] (DSRC) in Princeton, New Jersey, will operate special
event station N3P on "Pi Day," March 14, 2025. The event celebrates the March
14, 1879, birthday of Princeton's most famous resident, physicist Albert
Einstein, best known for his equation E = MC2, which states that energy and
mass (matter) are the same thing in different forms. Why call it Pi Day? If
you take the distance around a circle (circumference) and divide it by the
distance across the circle (diameter), you always get the number 3.14, the
value known as Pi, which also happens to be the date of Einstein's birthday.
N3P will be using CW and SSB, two modes in existence during Einstein's
lifetime: 14.031 (CW), 14.314 (USB), 7.031 (CW), and 7.227 MHz (LSB), from
2:00 PM to 9:00 PM EDT (1300-1900Z). The DSRC will also be monitoring the
club repeater, 146.46, for local contacts. To receive a special event QSL
card, send a self-ad

 dressed stamped business envelope along with your QSO information (call
sign, state abbreviation, band, UTC time of contact) to Bob Uhrik, WA2BSP,
104 Knoll Way, Rocky Hill, NJ 08553.


Alanson "Hap" Holly, KC9RP, retired founder and moderator of the weekly

Announcements

Registration begins mid-March for the 24th USA National Radio-Orienteering
Championships. This year's event takes place June 18 - 22 in the Uwharrie
Mountains of North Carolina and will be hosted by the Backwoods Orienteering
Klub [ https://backwoodsok.org/ ] (BOK) at Morrow Mountain State Park.
Radio-orienteers from across the country plus visitors from abroad are
expected to attend. The on-foot transmitter-hunting championships begin
Wednesday, June 18, with model events on two meters and 80 meters. Thursday
morning is the sprint, Friday is foxoring (a mix of foxhunting and
orienteering), Saturday is the two-meter classic, and Sunday is the 80-meter
classic. USA's ARDF Championships are open to anyone of any age who can
safely navigate in the woods with hand-held radio gear for several
kilometers. An amateur radio license is not a requirement. Medals are awarded
for each event in each of the IARU age/gender categories [
http://www.homingin.com/intlfox.html#categories ] . Winners

 of these championships will be under consideration for membership in ARDF
Team USA, which will travel to future international competitions. The name
Radio Orienteering has been around for a very long time and has frequently
been applied to the sport of Amateur Radio Direction Finding (ARDF). It
hasn't been recognized in any official sense. However, because Radio
Orienteering is more descriptive of the sport (especially to the orienteering
community), and because Amateur Radio Direction Finding is often confused
with other radio direction-finding activities (like mobile t-hunting), the
ARRL ARDF Committee [
https://www.arrl.org/arrl-ardf-committee?utm_source=Informz&utm_medium=Email&utm_campaign=ARRL
] has decided to officially favor the use of the term Radio Orienteering,
even renaming itself as the ARRL Radio Orienteering Committee.

The ARRL Solar Report

K7RA Solar Update - NASA SDO/HMI
[https://sdo.gsfc.nasa.gov/]


ARRL Solar Update February 27, 2025

The sun was active this past week, February 23 - 27, with several large
flares and coronal mass ejections (CMEs). While none of the flares were in
the direction of Earth, minor G1-class geomagnetic storms are possible on
March 1, when a stream of solar wind is expected to hit Earth's magnetic
field. The gaseous material is flowing from a large hole [
https://spaceweather.com/images2025/25feb25/ch2.jpg ] in the sun's
atmosphere, now squarely facing Earth.


There were no radio blackouts observed over the last 24 hours. Radio blackout
forecast for February 27 - March 1, 2025: R1 - R2 flares (minor-moderate) 65%
;R3 25% (strong) or greater February 27 - March 1.


The 10.7 -centimeter flux: 200 for February 27; 195 for February 28 - March
1; 190 for March 2 - 4.


Solar wind conditions are expected to remain enhanced on February 27 - March
1 with the influence of positive polarity. Coronal Hole High Speed Streams
(CH HSS) will influence, with further enhancement possible on February 28
related to the CME that was observed leaving the Sun on February 25.
