In this Issue: Upcoming Contests – Things to Do Contest Summary News, Press Releases, and Special Interest Word to the Wise Club Focus Sights and Sounds Results and Records Operating Tip Technical Topics and Discussion Conversation Contests Log Due Dates Upcoming Contests – Things to Do The upcoming weekend’s “major” is the CQ-only CQ WW WPX Contest. 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 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. 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.   Contest Summary May 28, 2026 - June 10, 2026   See the "Contests" section below for complete contest information.   Note: Contest dates and times are in UTC. This means that a contest that is listed to start on a Saturday at 0000z, for example, really starts on a Friday night in US time zones.   May 28 CWops Test (CWT) RSGB 80m Club Championship, CW May 29 NCCC FT4 Sprint Weekly RTTY Test NCCC Sprint K1USN Slow Speed Test May 30 CQ WW WPX Contest, CW May 31 Romanian Diaspora SSB Contest June 1 K1USN Slow Speed Test ICWC Medium Speed Test OK1WC Memorial (MWC) RSGB 80m Club Championship, Data ICWC Medium Speed Test June 2 ARS Spartan Sprint Worldwide Sideband Activity Contest ICWC Medium Speed Test June 3 Phone Weekly Test A1Club AWT CWops Test (CWT) VHF-UHF FT8 Activity Contest Mini-Test 40 Mini-Test 80 CWops Test (CWT) June 4 VHF-UHF FT8 Activity Contest-NA Walk for the Bacon QRP Contest CWops Test (CWT) SKCC Sprint Europe June 5 NCCC FT4 Sprint Weekly RTTY Test NCCC Sprint HA3NS Sprint Memorial Contest K1USN Slow Speed Test June 6 VK Shires Contest PODXS 070 Club Three Day Weekend Contest Tisza Cup CW Contest Wake-Up!

If you missed Contest University this year, the PowerPoint presentations and selected video presentations 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.”   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, MØDXR, 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” 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:   One can find a breakdown of band activity and most active OQRS accounts on Club Log in the report, as well. (Graphic courtesy of Club Log)   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 for CW, RTTY, and FT modes. Check your local listings for the dates and times.   A joint mission between the European Space Agency and Chinese Academy of Science is slated to provide more information on the Earth’s 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: www.facebook.com/share/v/1GQ6WQMWGx/. For more information on this year's event, please visit our website 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 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” 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 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 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)   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 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 other videos can be found at:   2025 CQ World Wide WPX Contest SSB Contest 2025 CQP Contest 2025 CQ WW DX SSB Contest   Don’t forget to check out the recorded “livestream” from the 2026 Contest University. Perhaps an index of links with timestamps of particular sessions will appear soon. Oh, wait, let’s ask Gemini: “This is a link to a livestream of a number of consecutive presentations: www.youtube.com/live/COq7v5pk96w. Can you provide an index of timestamps into the individual segments in this video to make finding content easier?”   Gemini: “Here is a timestamp index of the individual presentations and key segments from the Contest University 2026 livestream: [00:01] — Introductory Remarks & Welcome (Jim K1AR, K3LR, and introduction of the first professor) [01:43] — Presentation: Ethics and Reputation in Contesting (John Dorr, K1AR) [49:12] — Presentation: Contest Antenna Planning and Solar Cycle Strategies (Fred Hopengarten, K1VR) [02:04:39] — Presentation: Engaging Youth in Contesting (Violetta Latham, KN2P) [03:04:39] — Presentation: Designing and Rebuilding a Station (A Tale of a Summer Move) (Fred Hopengarten, K1VR) [04:37:49] — Segment: Eyeball Sprint Contest Briefing & Activity (Doug Grant, K1DG) [04:51:59] — Presentation: The Operating Wheel: Having Fun and Improving Your Score (John Dorr, K1AR) [05:32:34] — Presentation: The SET Approach: Enjoying POTA and Contesting Together (AJ Stockton, NK4O) [06:29:06] — Presentation: Basic Station Automation Techniques, Tips, and Tricks (Bob Wilson, N6TV) [07:06:34] — Segment: Antennas and Propagation Open Q&A Session (Moderated by Frank Donovan, W3LPL) [07:49:20] — Presentation: Transceiver Differences & The Clean Signal Initiative (Rob Sherwood, NC0B) [08:29:40] — Segment: Eyeball Sprint Contest Results, Awards, and Closing Remarks (Doug Grant, K1DG, and Tim Duffy, K3LR) You can view the full video directly on the DXEngineering YouTube Channel.   Results and Records The results for the 2025 ARRL 160-Meter Contest are in May’s issue of QST. You can also view the final scores on the ARRL contest website.   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, 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 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 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. The Digital Museum of Plugs and Sockets 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 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 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. It’s a sure bet that some amateurs worked on the systems described.   “The Surprisingly Long Life of the Vacuum Tube” 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.
