Upcoming Contests - Things to Do
The upcoming weekend's "major" is the CQ-only CQ WW WPX Contest [
https://cqwpx.com/ ] . It's an opportunity for US 2-1 contest or club
call signs with an overabundance of dah-filled characters to be heard
on the bands, such as the Kansas Exiles Amateur Radio Club call sign of
WQ0Q, to pick one out of thin air, so-to-speak. The contest's sponsor
has a Facebook page [ https://www.facebook.com/cqwpx ] where those
planning on operating can announce their intentions.
The weekend of June 6 has a variety of opportunities, including some
non-US field day events, the Kentucky QSO Party, and the ARRL
International Digital Contest [
https://www.arrl.org/arrl-digital-contest?utm_source=Informz&utm_medium=Email&utm_campaign=ARRL].
For the latter, any non-RTTY digital mode that can support the exchange
of grid square information would work, but the majority will be using
FT8 or FT4. Bands are 160, 80, 40, 20, 15, 10, and 6 meters. Note that
technician class operators can hang out on 10 and 6 meters. Automated
station operation is not allowed.
Yes, there's certain software out there that can make contacts on
digital modes which don't meet this rule for this contest.
Don't use that software, or the features that allow automated contacts,
in this contest.

News, Press Releases, and Special Interest
Now that Contest University 2026 has concluded, you may be pleased to
know that reservations for the Hope Hotel, location for Contest
University in 2027 [ https://www.contestuniversity.com/ ] , will open
on June 15, 2016. If you missed Contest University this year, the
PowerPoint presentations [
https://www.contestuniversity.com/https:/www.contestuniversity.com/files/
] and selected video presentations [
https://www.contestuniversity.com/videos/ ] are already available on
the Contest University website!
In other contest news from Dayton, Tim Duffy, K3LR, summarized the
TopBand Dinner: "Last Friday night was amazing. Jeff, K1ZM, presented a
once-in-a-lifetime history of 160 meters. It was beyond special. Thanks
to K1ZM! You can see Jeff's slides on the TopBand dinner website [
https://www.topbanddinner.com/presentations ] ."
John Ross, KD8IDJ, writes in The ARRL Letter "At Saturday night's
Contest Dinner, sponsored by the North Coast Contesters, an
international audience of nearly 500 people cheered the induction of
four notable competitors into the Contest Hall of Fame, established by
CQ magazine in 1986 and administered today by the World Wide Radio
Operators Foundation (WWROF). This year's inductees are Doug Zwiebel,
KR2Q, who revolutionized contest scoring by writing the first mass
computerized log-checking software back in 1980; Tom Lee, K8AZ, who
helped shape modern regional contest club structures as a co-founder of
both the North Coast Contesters and the WWROF; Tom Young, K1XM, who
created both the Yankee Clipper Contest Club SO2R (Single-Operator 2
Radios) Box hardware and the widely-used Open Two Radio Switching
Protocol; and Mark Pride, K1RX, antenna director for the 2014 World
Radiosport Team Championship (WRTC) and producer of a 7-part series on
contesting for the Q5 Amateur Radio podcast. The 2026 WRTC, to be held
in the United Kingdom this July, was also on the Contest Dinner menu,
as the competition's chairman, Mark Haynes, M0DXR, was the keynote
speaker.
Emcee and famed contester John Dorr, K1AR, added a light and humorous
touch to the evening."
Club Log publishes the "Club Log DX Report
[https://clublog.org/dxreport.html ] " each week, compiled from the
contacts that Club Log users upload. For the period of May 13, 2026, to
May 20, 2026, mode usage on the bands looked like this:
It's a good idea to test your contest configuration before the contest,
especially if you've upgraded any part of your "contesting stack" of
device drivers, logging program, digital mode software, operating
system, etc.
Those weekly N1MM Logger+ versions, that recent WSJT-X software
release, and so forth, may have issues or configuration that you need
to do before the contest.
Windows users should be especially wary of driver updates that can
rename COM ports.
One good way to test before a contest weekend is to take advantage of a
weeknight contest practice session, like those run by the Northern
California Contest Club [ http://nccc.cc/ ] for CW [
https://www.ncccsprint.com/ ] ,
RTTY [https://ncccsprint.com/rttyns.html ] , and FT modes
[https://www.ncccsprint.com/ft4ns.html ] . Check your local listings for
the dates and times.

magnetosphere. The Solar wind Magnetosphere Ionosphere Link Explorer
(SMILE) was launched last Tuesday from French Guyana, and will end up
in an elliptical orbit varying between 5,000 - 121,000 kilometers as it
passes over the south and north poles.
On board are X-ray detectors that will be used to observe the north
pole's auroral activity for up to 45 hours at a stretch.
Ash, 3V8SS/KF5EYY writes: "The IARU High Speed Telegraphy World
Championship is back in Tunisia this year.
After the 2024 success, we are organizing this nice (off the air)
championship in the touristic city of Sousse on the Mediterranean
coast.
It's a nice opportunity to enjoy competing in Morse code, celebrating
it as a world heritage while enjoying the friendship and the country.
Last year we had 125 participants from 14 countries. We are looking
forward to having more people joining this year.
Here is a video from the 2024 version:

[ https://www.hst2026-tunisia.org/ ] . Looking forward to having you
here in Tunisia!"
Uwe, DG2YCB, announces: "At the request of several OMs, we have now
integrated the new call sign overlay feature introduced with QMAP v0.7
into WSJTX and MAP65 as well. With MAP65, it certainly makes sense to
have an option available to display decoded call signs on the
waterfall; with WSJT-X, it's a matter of personal preference, because
on crowded bands, things can quickly get a bit confusing.
We have therefore introduced additional color coding there: a
black/white background indicates even/odd; and orange text indicates
stations that have sent CQ (or RR73, if that highlighting option is
enabled). The call sign in the DX call box is displayed in green.
And you can select 3 font sizes for the call sign overlays. The call
sign overlay feature can be enabled or disabled in the View menu. QMAP
and MAP65 have additional controls in the Wide Graph window (bottom
right). For QMAP and MAP65, the Tol value is now saved and restored.
And of course, this build still offers 256 kHz (sampling) support for
QMAP. As usual, all packages are available on my SourceForge page.
Currently, 64-bit Windows and Linux builds of this new 260516 (beta)
release of WSJT-X Improved 3.1 are available for download and testing,
as well as the source code."
Word to the Wise
WARC bands
The year 1979 was 47 years ago. That was when the 12-, 17-, and
30-meter bands were approved for amateur radio use by that year's ITU
conference, with an agreement among nations that they are not to be
used for radio contesting. The "WARC bands" are 12, 17, and 30 meters.
Club Focus
"Potomac Valley Radio Club: Champions of Contesting and Community
Support" in the May 2026 issue of QST [
https://edition.pagesuite.com/html5/reader/production/default.aspx?pubname=&edid=146fe8f7-8a32-4081-8a
0c-d1708985f2e4&pnum=66 ] talks about how PVRC gives back to amateur
radio by sponsoring scholarships via the ARRL Scholarship Foundation
Program, and raised funds to sponsor a teacher to attend the ARRL
Teachers Institute on Wireless Technology.
"PVRC and ARRL make it easy for their members to contribute ... via the
ARRL website, club members may designate their donations for the
scholarship, the Teachers Institute, or both.
Additionally, PVRC collects donations directly from its members and
distributes them to ARRL and the ARRL Foundation."
Sights and Sounds
Ken Claerbout, K4ZW, presented "The Challenge of DXing in Africa [
https://www.youtube.com/watch?v=6lD8WyLXw1c ] " at the Madison DX Club.
Some groups travel to put a rare country on the air for major DX
contests, and the experiences and advice that Ken provides may help
with planning. Kudos to the Madison DX Club [
https://www.madisondxclub.org/ ] for putting their meetings on YouTube
for anyone to benefit from -" it builds their authority and brand while
providing a service to the hobby.
Dave Gilbert, AB7E, built a browser-based application that takes stereo
audio from your phase-locked dual-receiver equipped radio to use
diversity to separate signals from one another and the noise.
Then he made a video: "I recently posted a link to a video of a
browser-based application I created with the help of ChatGPT to enhance
diversity reception.
I've made a couple of significant improvements to the application
(which happens to be completely free of charge) so I uploaded a new
video [ https://youtu.be/DfEjzlANWAw ] that illustrates how well it can
be used to separate signals from other signals, or from noise.
If you don't watch any other part of it, check out the segment starting
at 29:15. To use this app, you simply feed the normal stereo diversity
audio (Line Out) from the phase locked receivers into the Line In port
of a computer sound card.
The application does the rest.
(via the Elecraft mailing list [
http://mailman.qth.net/mailman/listinfo/elecraft ] )
Tom, NS6T, has produced some new videos visualizing contacts made between
hams during contests.
The description of the 2025 CQ World Wide DX Contest CW [
https://youtu.be/xf1V4VagvEk ] visualization is: "This is a graphic
visualization of the ham radio contacts made during the 2025 CQ World
Wide DX Contest CW (Morse Code). This shows the great circle path for
contacts on a Winkel-Tripel map showing the illuminated portion of the
globe.
Color and tone indicate the amateur radio band that the contact took
place using.
Each path that shows up on the map represents a 2-way contact between
ham radio operators.
The paths shown are the great circle paths (i.e., the shortest path on
the Earth between the two points). On a flat map, these paths appear
curved, but on a globe, they would look straight.
In many cases, the locations of the stations are approximate." The

Operating Tip
This is more a station building and layout tip.
Magnetically coupled noise may be a problem in the rat's nest of cables you
see under the average operating position.
Hal Kennedy, N4GG, talked about this in his Contest University presentation [
https://www.contestuniversity.com/wp-content/uploads/2026/05/Pg.-31-N4GG-MorningRevision1.pdf
] , and suggested some practical things to do to minimize the coupling
effects from noise generators and noise conductors.
Keep coax at least 6 inches away from switching power supplies of any kind.
Don't bundle signal cables and power cables together.
The slides are worth going through, and I'm looking forward to the posting of
the video of the presentation.
Technical Topics and Discussion
Kydex [
https://www.curbellplastics.com/materials/plastics/kydex-thermoplastic-sheet/
] is a branded thermoplastic that can be heat-shaped, drilled, and machined.
You've probably seen it without realizing it in airplanes, department stores,
and vehicles. By heating it and vacuum-forming it, enclosures can be made for
outdoor equipment, and "kydex radio holder"searches on Etsy [
https://www.etsy.com/market/kydex_radio_holder ] show a number of people
using it for ham gear.
Power cords, and the equipment that uses them, are characterized by a
standard -" IEC 60320 [ https://en.wikipedia.org/wiki/IEC_60320 ] . The
Digital Museum of Plugs and Sockets [ https://plugsocketmuseum.nl/ ] has a
page devoted to this standard, with pictures of some of the more common ones.
The reason some connectors are transparent? Better to be able to note the
conditions of the internal connections.
Apple's recent 26.5 software includes a new "Power Control" setting [
https://www.tomsguide.com/computing/macos/the-mac-minis-ridiculously-placed-power-button-just-became-i
rrelevant-thanks-to-this-new-macos-26-5-feature-heres-how-to-activate-it
] that will enable Mac Mini, Mac Studio, and iMac to automatically boot when
power is applied to the device. This capability was previously only available
with their server-oriented products. Apple is touting this as an
accessibility feature.
Argonne National Lab researchers have found a material that conducts heat
three times better than copper [
https://www.anl.gov/article/researchers-discover-recordsetting-heatconducting-material
] or silver. The material, metallic theta-phase tantalum nitride, could find
use in conducting heat away from silicon chips, allowing greater densities
and higher speeds. Conducting heat away from LDMOS dies would also be a nice
application.
Extremely low frequencies (ELF) used to communicate with military assets are
the focus of this article [
https://computer.rip/2026-05-09-extremely-low-frequencies.html ] . It's a
sure bet that some amateurs worked on the systems described.
"The Surprisingly Long Life of the Vacuum Tube [
https://www.construction-physics.com/p/the-surprisingly-long-life-of-the ] "
is a readable history of how they work, and how they've evolved over time.
Conversation
A Boomlet in Ham Radio Software?
I've written about AI in this spot for a few years now. There's a consensus
that in early 2026 there was a "breakover point" where the tools became much
more powerful and useful, and even those that were skeptical of the utility
of using them were starting to find they were helpful. Today, if your product
depends on software at all, it can likely be improved by applying AI tools to
some part of the coding, tooling, organization, documentation, bug fixing, or
design.
There is no question that the proper use of these tools is a force
multiplier. There's no benefit to side with the Luddites and insist on "100%
crafted by humans." The humans provide the creativity and direction; the AI
can do the work. Especially the boring parts.
We're now seeing an overall modernization in some of the tools and technology
that we use in our hobby. Any component that uses a non-mainstream
development environment or development language is ripe for modernization
purely by asking an AI to update it to be compiled with modern tools.
Spot processing is getting a brand-new take, courtesy of N2WQ's re-think and
quality time spent with his AI pal Claude.
The WSJT-X project is modernizing with automation of cloud builds, addition
of test frameworks, and moving to more modern open software processes.
Some radio vendors are following the lead of "big" software development in
improving their issue resolution times by letting AI have first crack at
reported bugs.
I suspect that log checking is getting better with AI help.
AI may also be able to bring younger people and new interest into the
underpinnings of our hobby by flattening the learning curve to get involved.
And that's a good thing, right?
That's all for this time. Remember to send contesting-related stories, book
reviews, tips, techniques, press releases, errata, schematics, club
information, pictures, stories, blog links, and predictions to
