Spring is a good time to do that. Other good times are Summer, Autumn, and Winter, BTW. The weekend of April 4, look for more casual activity in the Louisiana [ https://laqp.w5gad.org/rules ] and Mississippi [ https://arrlmiss.org/mississippi-qso-party/ ] QSO Parties. Both events are only 12 hours long. Louisiana's includes a POTA category overlay for operation from "POTA, Campground, or Federal Wildlife Refuge." Other overlays are for wire-only or tribander-and-wire antennas. Mississippi allows the use of FT4/8 in addition to CW, SSB, and RTTY by just exchanging signal report and grid square. DXers might enjoy the SP DX contest [ https://spdxcontest.pzk.org.pl/2024/rules.php ] , and RTTY operators will have the EA RTTY Contest [ https://concursos.ure.es/en/eartty/bases/ ] . April 11, there are four QSO Parties: New Mexico [ http://www.newmexicoqsoparty.org/ ] , Missouri [ http://www.w0ma.org/index.php/missouri-qso-party ] , Georgia [ https://gaqsoparty.com/ ] , and North Dakota [ https://ndarrlsection.com/2026/2026_nd_qso_party_rules.pdf ] . All offer a mix of modes, and an opportunity to work some of the rarer counties in those states. The N1MM Logger+ FAQ [ https://n1mmwp.hamdocs.com/faq/#how-can-i-best-handle-multiple-contests-the-same-weekend ] has a section on how some people handle being in multiple contests at once. CW operators will enjoy the 30-hour JIDX Contest, where JA operators send RST and a prefecture (01 to 50), DX sends RST and CQ Zone. Only JA to DX contacts are worth points in this contest. If propagation is available on 10 and 15 meters, there will be a lot of stations to work.

Switch SO2R Controller [https://rigselect.com/] News, Press Releases, and Special Interest The Reverse Beacon website [ https://reversebeacon.net/ ] 's search functionality now has the ability to search spots via multiple spotter callsigns, simultaneously. According to Bob, N6TV: "In the past, you could enter a list of DX callsigns but only one spotter callsign. This update is particularly useful if you have multiple skimmers going with unique SSIDs all using different antennas but with overlapping bands." He cites as an example the ability to search for spots originated by KM3T-1, KM3T-2, and KM3T-3 with this URL [ https://reversebeacon.net/main.php?rows=100&max_age=20,minutes&spotter_call=km3t-1,km3t-2,km3t-3&hide=distance_km ] . In a recent post to the CQ-Contest email list [ http://lists.contesting.com/mailman/listinfo/cq-contest ] , Pete Chamalian, W1RM, noted one reason why some contest stations sometimes use a "unique" exchange: "In 1967, I and a group of CW enthusiasts from the Connecticut Wireless Association (CWA) went to PJ5ME for ARRL DX. We only operated one weekend. Many of the team were using bugs so picking a power that would be easy for them to send got us to (use) 599055 (T55). It was a masterstroke because many of the contesters came to quickly recognize that and knew who we were (they were easy to identify during the contest from just listening to the exchange - remember, this is before internet spotting - Ed.) That spring, W2ADE and I went to Dayton and put on a show about PJ5ME. The audience was all talking about the power and what a stroke of genius it was." Here's a more modern way to "stand out" - during last weekend's WPX phone contest, K9CT's station was using the NH8S (Swain's Island) call. Those enthusiastic contesters that read online sources like The Daily DX [ https://www.dailydx.com/ ] , various contesting groups on Facebook, and so forth, would know that NH8S was going to appear in the contest, and treated the NH8 prefix as just another prefix in WPX. For everyone else hearing NH8S, it might have been appealing to work NH8S, not immediately knowing it's in Illinois. The exchange is just the report and a serial number, so that didn't help to identify the location of NH8S. Also heard during WPX: AH2O, another frequent active contester, was located in NY - ARRL NLI section. I also seem to recall a non-continental-US station signing with a /WE7 suffix... "The dates of Missouri's participation in the ARRL's America250 WAS program are changed to: 20-26 May (new dates) 14-20 Oct (original dates) This change has been made to avoid the Apr 11-12 Missouri QSO Party (www.w0ma.org/index.php/missouri-qso-party [ https://www.w0ma.org/index.php/missouri-qso-party ] ) which uses special 1x1 call signs and other special scoring based on call sign. The week-by-week activation chart for 250WAS [ https://www.arrl.org/files/file/Year Of The Club - America250-WAS/2026 America250-WAS--YOTC--Proposed-W1AW-Activation--V0326.pdf ] has also been updated. 73, Ward N0AX Missouri Coordinator for America250 WAS" The 2026 SP DX Contest [ https://spdxcontest.pzk.org.pl/ ] (Poland) is happening the weekend of April 4, 2026. It's expected that over 1000 Polish stations will be on the air for this CW and SSB contest. All logs are due by April 12, 2026, and must be uploaded via the website. The contest sponsors promise to publish final results by May 4, 2026. You could qualify for one of the many plaques sponsored by various groups and individuals - see the website for details. "Using the DX Cluster and spotting networks is permitted in the SP DX Contest in all categories. Self-spotting is allowed." SP stations will be sending RS(T) and a single letter, denoting the province (Voivodeship). Non-SP stations send RS(T) and a serial number. Word to the Wise "Bug" A mechanical key [ https://www.arrl.org/the-first-bugs?utm_source=Informz&utm_medium=Email&utm_campaign=ARRL ] that generates dots and dashes by (for example) manipulation of paddles, and the swinging of a weight against a spring. Element length and spacing is controlled by mechanical adjustment. One current manufacturer is Vibroplex [ https://www.dxengineering.com/parts/vib-original-d ] . Enthusiasts enjoy them as much for the mechanical art aspects as they do for their functionality, perhaps more. Club Focus Bob, W4GJ, writes: "The W.T. Loften High School Amateur Radio Club is located in Gainesville, Florida. We have 65 students who are mostly in our Fire/EMS Academy. We regularly activate Special Events like National Fire Prevention Week, National EMS Week, National Police Week, and the Florida QSO Party. We also are active in ARES, Winter and Summer Field Day, School Club Roundup, and a new Special Event; the U.S. Constitution Week. Listen for our students operating K4WTL, N4F, N4E, N4P and W4C. We have an ECOMM trailer that we take away from campus. We man Red Cross shelters during hurricane season as communicators. We mostly operate SSB and CW on the HF Bands. Our students are very competitive and even our freshmen are excellent operators! We are proud charter club members of the ARRL with most of our students having student memberships in the ARRL." Results and Records Ed, W0YK, notes that the preliminary results of the recent 2026 RTTY Sprint are posted [ https://ncjweb.com/sprint-scores/preliminary/sprintrttymar2026prelim.txt ] . "Currently there is no reason that these aren't also the final results." If you'd like your LCR (log checking report), email Ed. Bill, AC0W, announces that the results for the 2026 Minnesota QSO Party have been posted [ https://www.w0aa.org/wp-content/docs/mnqp/MNQP_2026_RESULTS_B.pdf ] . "Congratulations to the category winners and thanks to those who participated for adding to the fun." In 2026, over 3500 unique call signs appeared in submitted logs. Next year's event will be on February 6, 2027. Operating Tip Rob Fanfant, N7QT, posted this tip to the Western Washington DX Association email reflector: "Want to learn a fast way to switch between Hound and Super Hound modes (in the WSJT-X program)? With Hound mode or Super Hound mode selected (i.e. the "H" button is RED), just right mouse-click over the H button! You now have a very fast way to transition between SH and H modes! I'm running WSJTX V.3.0.0-rc1, so your mileage might vary if you aren't." Technical Topics and Discussion Mike Lewis, K7MDL, has been working on a "modernization" of the hardware and software [ https://groups.google.com/g/pnwvhfs/c/iqai879X5Zk ] used with K3NG CW keyer [ https://github.com/k3ng/k3ng_cw_keyer ] open source software, which itself is a work-alike of K1EL's WinKeyer [ https://www.hamcrafters2.com/ ] . N1MM Logger+ has supported WinKeyer for CW generation for a very long time. Mike's changes include adding support for the powerful and ubiquitous ESP-32 and Raspberry Pi platforms, and support for Bluetooth keyboards. This hardware is found in many popular designs and often include peripherals like Wi-Fi, USB-C, Bluetooth, color LCD displays, and buttons, at very attractive prices; they're also readily available from Amazon and other sources. His latest improvements include a keyer UI layout that utilizes larger 320x480 displays, and support for ESP32-WROOM and Pico 2W. His work can be found in his Github repository: github.com/K7MDL2/K3NG_Keyer_ESP32_BT_Keyboard [ https://github.com/K7MDL2/K3NG_Keyer_ESP32_BT_Keyboard ] . Pre-compiled binaries can also be found at that location for those that want to assemble one of these, without compiling the software themselves. The capabilities of AI tools are changing so quickly that learning how to best use them also changes day-to-day. Beyond just asking questions in a "chat style" interface, you can turn AI agents loose on documents, code, or even websites via web browser integration [ https://gemini.google/overview/gemini-in-chrome/ ] . Here's an AI template [ https://github.com/pangon/ai-sdlc-scaffold ] that you can use with Anthropic's Claude [ https://claude.com/ ] to get the AI to elicit a software project's outline, refine the design, accumulate documentation, and work on the project. The template is illustrative of how an AI can be given rules that are followed for the project, and how new commands can be defined for an AI. Craig, VK3OD, encountered horrific interference from a neighbor's Bitcoin mining rig across all of the HF bands. The neighbor, located approximately 750 meters away, was cooperative in the solution to the problem which involved adding chokes on the power supply leads. It appears that the power supply manufacturer may have eliminated filtering in their design to save costs. He details how he solved it on his post to the RFI email reflector [ http://lists.contesting.com/pipermail/rfi/2026-March/022686.html ] . The discussion includes input from others about the alternative EMI filter design, and repeatability in duplicating the filters. Joe, W2QQ, notes in the N1MM Logger+ groups.io group [ https://groups.io/g/N1MMLoggerPlus/message/99807 ] , that microphone type is important when recording your voice for training an AI model. Basically, do what the instructions say, and do not get fancy with the microphone: "The training documentation recommends use of an electret microphone and my experimentation proved this to be the best choice by far. I started with boom mic on a set of Logitech headphones and the recordings were basically unusable. Next, I tried recording with a dynamic mic. I was able to make the recordings, but after running the full Piper training, I found that the voice was very muddled and lacked any punch. Not at all good for contesting. Finally, I made the recordings with an inexpensive (about $15) electret mic. This worked like a charm. The recordings were made with sufficient gain and no clipping. The result of the training was a voice that had considerably more punch than those from the dynamic mic. So, I strongly suggest that if you are going to embark on the Piper TTS training, you use a simple electret mic plugged into your computer's soundcard." Conversation During the WPX this weekend, I had started my before-sunrise shift at our multi-op the way I sometimes do, by knocking off some multipliers using spots, made much easier by using the AMQ (available multipliers and QSOs) window in N1MM Logger+ to step through the list of spotted mults, before looking for and settling in to a run frequency. I was a little groggy from traveling back home from a few time zones away the previous day. The 20 meter band wasn't quite open, but I was hearing a few mults, and working a few. I'd just found another multiplier, and was listening to another US station work them. I'm not sure what it was, but something just seemed a little off with the cadence of the QSO, or maybe it was that the multiplier wasn't as busy as I thought they'd be? I looked at everything on the screen and noted that the frequency displayed on the entry window was not in the US 20 meter phone band. Working that station on that frequency would have been against both the contest rules, and US rules for Phone on that band. Operator aids like the AMQ window could be "enhanced" with more settings and rules and configurations so that spots of stations are not displayed when they're outside of my privileges... but ultimately it's the responsibility of me, the operator, to know when and where to transmit. That's all for this time.
