Contest Spotlight: ARRL Digital Contest This weekend brings the 2026 edition of the ARRL Digital Contest. The stated objective of the contest is to exchange QSO information with other amateurs using any digital mode with the exception of RTTY in modes that support the exchange of a four digit Maidenhead Grid Square. The contest starts on 1800 UTC on Saturday (2 PM Eastern Time on Saturday) and ends 2359 UTC on Sunday (7:59 PM Eastern Time on Sunday). Bands in play are the 160, 80, 40, 20, 15, 10, an 6 meter bands and observation of established band plans is strongly encouraged. Operating categories are Single Operator (Low Power and QRP) and Multioperator (Low Power and QRP). There are no high power categories. Single Operator stations can work 24 of the 30 hours and Multioperator stations can work the full 30 hours. Stations can contact any other station once per band. The exchange is the 4 digit Maidenhead Grid Square locator. For my QTH that would be FM18. Any digital mode except RTTY can be used, but FT8 and FT4 are likely to be the most popular. For scoring each QSO counts for 1 QSO point plus an additional point for each 500 km of distance between the centers of the 4 digit grid squares of the two stations, rounded up to the next highest value. There are also club competition and team competition options. All logs must be submitted electronically in Cabrillo format within 7 days after the end of the contest. This promises to be a fun contest for the digital operator. For full rules and information visit https://www.arrl.org/arrl-digital-contest. Good luck. CHU Canada Shortwave Time Station Shutting Down 6/22/2026 A familiar companion on the HF bands is about to sign off the air. CHU Canada, the time signal station that broadcasts time signals on 3.330 MHz, 7.850 MHz, and 14.670 MHz is scheduled to shut down on June 22nd. CHU’s signal has been easily heard in the United States and around the world with its broadcasts of time announcement by voice and also via digital time codes. It is broadcast in Upper Sideband with a carrier reinserted to allow it to be received without an SSB radio using three atomic clocks located at the transmitter site and the signals are highly accurate. In addition to providing the time, the signals were used by many to gauge ionospheric propagation conditions. Recently HamSCI, an organization engaged in citizen science using amateur radio, released a statement on how they have been actively using the signals from CHU to further their research, formally asking the Canadian National Resource Council (NRC) which operates CHU to reverse their decision to close the station. The decision to end CHU broadcasts follows the closing of Canada’s weather radio network on March 16 earlier this year. If the station does indeed stop broadcasting this month, it will be greatly missed.

Lord Howe Island is a volcanic remnant in the Tasman Sea between the East Coast of Australia and Norfolk Island. The team will be focusing on 40 through 10 meters on CW, FT8, and SSB and they are livestreaming via ClubLog. As we went to press the team had logged over 6,940 QSOs and were working a big pileup on 17 meter CW. They are scheduled to continue their operations until June 14. More information about the DXpedition can be found at https://www.dx-world.net/vj2l-lord-howe-island/ and their livestream can be found at https://clublog.org/livestream/VJ2L. Good luck. ARRL Announces Product Comparison Tool The American Radio Relay League (ARRL) has announced the release of their QST Product Review Database. It allows amateurs to compare various amateur radio products based upon metrics evaluated by the League. The site includes every lab tested device featured in QST since 2012 and allows users to filter based on the parameters most of interest to them. It also allows users to jump into the reviews in past issues of QST. To get full access to the data an ARRL membership is required. The database can be accessed at https://compare.arrl.org/. MVARC Nets on the Air * 2 Meter FM Net: Tuesdays at 7 PM [146.655/- MHz (141.3 Hz PL Tone) ] * 2 Meter Digital Net: Immediately Follows 2 Meter FM Net [146.655/- MHz C4FM] * MVARC Slow Speed CW Roundtable: Saturday and Sunday at 7:30 AM [3.565 MHz CW] * MVARC Cherry Tree Net: Saturday and Sunday at 8:30 AM [3.920 MHz LSB] What’s Happening with DX There will be a lot of DX on the air this week.

Solar Activity Update As we go to press the Solar Flux Index (SFI) was 148 and the estimated sunspot number was 157 with 8 numbered sunspot regions visible from Earth. Over the last week the SFI stayed about the same. Solar activity has been at low levels in the last 24 hours. The geomagnetic field has been at quiet to unsettled levels in the last 24 hours and the Kp index reached 3 yesterday. The solar wind peaked at 481 km/s. Solar activity is predicted to be at low levels with a chance of M-class flares and a slight chance of X-class flares today through Sunday. The geomagnetic field is forecast to be at active to severe storm levels today and at quiet to active levels on Saturday and quiet to unsettled levels on Sunday. The chance of solar radiation storms at the S1 or greater level is at 5% today through Sunday. R1 to R2 radio blackouts are likely with a predicted probability of 50% today through Sunday. R3 or greater blackouts are possible with a 10% chance predicted today through Sunday. It remains a fantastic time for amateurs to get on the air and work the world.

    Amateur Radio News and Notes 5/29/2026

    In the log this week * Contest Spotlight: CQ World Wide WPX Contest (CW) * Free Online Field Day Training From Long Island CW Club * MVARC Nets on the Air * What’s happening with DX? * Solar Activity Update * Upcoming Contests * Interesting Online Radio Content As always, links to all referenced content can be found in the show notes, or at our Substack at mvarc.substack.com. Thanks for reading Amateur Radio News and Notes. Subscribe for free to receive new posts and support my work. Contest Spotlight: CQ World Wide WPX Contest (CW) This weekend brings one of the biggest contests of the year: the CQ World Wide WPX Contest on CW. This is another contest where you can work a ton of DX, but what makes this one special is everyone can work everyone. The WPX part of it is referring to an interesting component of the contest where different call sign prefixes are the multipliers. So for me, the prefix would be “N2”, so if you worked me you’d get a multiplier. But “W2” would be another, as would “K2”, throw a different number in there and then you get still more, so the points escalate quickly and almost all contacts are “good contacts”. The contest starts at 0000 UTC on Saturday, May 30 (8 PM ET Friday Night), and ends on 2359 UTC on Sunday (7:59 PM ET Sunday). During that period of time a single operator can work 36 of the 48 hours and any off-times must be a minimum of an hour with no contacts logged. Bands allowed for the contest include 160m/80m/40m/20m/15m/and 10m. The exchange is RST plus a serial number, so “599 42” if you’re someone’s 42nd contact. Make sure you get the serial number, as it is required to match for the QSO to count. The final score is the QSO Points x Number of Prefixes Worked. QSO Points are 3 for contacts on different continents on 10m/15m/20m and 6 points on 40m/80m/160m. On the same continent but different countries points are 1 point on 10m/15m/20m and 2 points on 40m/80m/160m. Finally contacts in the same country are 1 point on all bands. The Prefix multipliers are applied only once, regardless of band or frequency of operation. Prefixes are the combination of the letters and numbers on the first half of the call, so N4, W4, WA4, S51, LY1000, are all separate prefixes to be counted. For entry, single operator categories include High Power (not exceeding 1500 Watts), Low Power (not exceeding 100 Watts), QRP (not exceeding 5 Watts). There are also a bunch of overlay categories that can be entered alongside your main category like Tribander, Rookie, Classic, and Youth. Check the rules for details on these. There are also Multi-Operator categories including Multi-One, Multi-Two, Multi-Unlimited, and Muti-Distributed. Again check the rules for full details. Rules and more information can be found at https://www.cqwpx.com/. This is always a great contest to make lots of contacts and get all kinds of unique prefixes into your log. Have fun and good luck! Free Online Field Day Training From Long Island CW Club The Long Island CW Club was founded in 2017 by Howard WB2UZE and Rich K2UPS after Field Day that year in the hopes that they could get more CW operators on the air for future Field Day outings. What they started in Long Island nearly 9 years ago has since grown to an impressive scale with 8,100 members in all 50 US States, and 71 Countries around the globe. They currently teach 182 classes a week covering Morse Code as well as a wide variety of topics of interest to the radio amateur. Getting back to that founding desire to promote CW on Field Day, the club is offering free classes to all via Zoom during the month of June focusing on practical CW skills for Field Day operation. They go over the Field Day exchange, getting into the rhythm of operating, abbreviations you’re likely to hear on the air, and practical advice on building your skills in sending, receiving, and confidence on the air. I have been an instructor with the Long Island CW club for many years now teaching classes at the beginner, intermediate, and advanced levels and the organization’s commitment to quality education and a welcoming community is second to none. The Field Day classes are free to all and start on Monday, June 1st, 2026 in a public Zoom room. As we go to press there are classes scheduled Sunday-Thursday for both Field Day CW Training and Practice and Advanced Field Day Training being offered. A full calendar of classes with a link to the Zoom room can be found at https://longislandcwclub.org/2026fieldday/. So stop on by for some classes and get on the air with CW during this year’s Field Day and get all those extra points. Good luck!

Stations on the air include Galapagos (HD8R, HC8M), Western Sahara (S09S), Kenya (54Z/MM0ZBH, 5Z4A), French Polynesia (FO/F6CBW), Mauritius (3B8IDX), Juan Fernandez Island (3G0Z), Namibia (V5/N7XOB), Palau (T88PB), Tonga (A31WW), Saint Kitts and Nevis (V4/WW6W), Chatham Island (ZL7IO), Martinique (TO3E), Bolivia (CP7DX), Bonaire (PJ4CB), Azerbaijan (4K0T), Maldives (8Q7QR), Panama (3F1A), Market Reef (OJ0MN, OJ0Z), Lord Howe Island (VJ1L), Macao (XX9AN), Tanzania (5H1KB), and Rwanda (9X5KM). A calendar of DXpeditions can be found at NG3K’s Announced DX Operations List at https://www.ng3k.com/misc/adxo.html. Solar Activity Update As we go to press the Solar Flux Index (SFI) was 145 and the estimated sunspot number was 161 with 11 numbered sunspot regions visible from Earth. Over the last week the SFI has increased. Solar activity has been at low levels in the last 24 hours. The geomagnetic field has been at quiet to active levels in the last 24 hours and the Kp index reached 4 yesterday. The solar wind peaked at 491 km/s. Solar activity is predicted to be at low levels with a chance of M-class flares today through Sunday. The geomagnetic field is forecast to be at quiet to unsettled levels today and Saturday and at quiet to active levels on Sunday. The chance of solar radiation storms at the S1 or greater level is at 5% today through Sunday. R1 to R2 radio blackouts are possible with a predicted probability of 40% today through Sunday. R3 or greater blackouts are unlikely with a 5% chance predicted today through Sunday. It remains a fantastic time for amateurs to get on the air and work the world.

Dayton Hamvention 2026 Recap The 2026 edition of Dayton Hamvention took place on May 15-17, 2026 and Amateur Radio News and Notes was there. There were new product announcements from Icom and Yaesu, scores of vendors and flea market attendees selling their wares, many forums to attend, and several awards given to individuals and organizations of note in the amateur radio hobby. Perhaps the most anticipated announcements of Hamvention were those from Icom. They had several new and upcoming items on their list including ID-5200 mobile VHF/UHF rig which was on display with support for APRS and a Bluetooth KISS TNC. A price and release date has not yet been announced, but it is likely to be released at Tokyo Ham Fair later this year. Also announced was a new microphone and the AH-6 automatic antenna tuner, and both have no announced release date. The big tease from Icom was for their X-026 prototype. They had a plastic mockup under glass, but it was just a black box with no details on it and Icom staff were more interested in getting attendees thoughts on what it could be than giving specifics. Amateur Radio News and Notes was able to get some time with Icom’s Ray Novak N9JA to talk about what they brought to Dayton. Amateur Radio News and Notes: Hey, we’re here with Ray Novak here at the Icom booth, N9JA, and of course everybody knows Ray. Ray, you’ve got a lot of things being announced here, some a little more, real than others, some still in the prototype phase. Tell me about what, what we’re looking at here, new stuff here from Icom. Ray Novak N9JA: Well, a couple of the things here, we’re in various stages of prototypeness here. We’ve got the new X026 which is in a design concept, you know, one of those molded vehicles at the auto show that everybody goes, “Oh, that is so cool,” and then in the automobile industry maybe 20 years later they finally release the Tonka version of the Bronco. That took forever. But then we’ve got a microphone that is designed by the JAIA. I’ve heard that it looks like one of the Heil microphones, the PR781, uh, had somebody else tell me it looks like a Rode microphone. I haven’t had a chance to play with it to see what the front to back looks like, but it’s got in it the, uh, buttons to trigger—like I said I haven’t had a chance, but it looks like it triggers the digital voice keyer in the radio. Uh, we’ve got two almost production prototypes here, one being the AH6 which is 160 through 6 meters, both a random wire or a coax fed antenna system. And then finally the ID5200. Amateur Radio News And Notes: Well very good. Well, I’m very excited. I know there’s a lot of buzz around the, uh, the X026. I know you and I were talking a little earlier, might be a little while before it goes to market, but a lot of lot of speculation. Do you, do you have any, any favorite guesses you’ve been hearing, because I know a lot of people have been asking about it. Ray Novak N9JA: The more favorite guesses I guess I could say isn’t the ones where they’re like speculating what bands it will do, it’s more what would you like to see outside the box. And those, those have been the ideas that I’ve liked the most because it gives me an idea of hams thinking differently. Instead of just where does the microphone plug into, how long is the remote head cable, I want to see it do this band, that band, the other, I want the typical things that you would expect out of a black box. But I’m having fun hearing some of the things like what we did in the ID5200 with Wi-Fi, Bluetooth, APRS, things like that. So those, those are the fun outside... it’s definitely outside the Icom box with like the APRS. Amateur Radio News and Notes: Fantastic. Well Ray, thank you so much for your time. I know you’re busy, got a lot of people going to talk to you but I appreciate you spending some time with us and, uh, look forward to seeing all this stuff out in the market. Ray Novak: Alright, thank you very much. Another highly anticipated set of announcements was from Yaesu. They announced the latest version of their digital voice system, Yaesu System Fusion III, along with their new DR-3X Repeater Systems. No price or release dates were announced, but Amateur Radio News and Notes spoke to Cory Sickles WA3UVV to learn more about what Yaesu announced at Dayton. Cory Sickles WA3UVV: Sure, I’m I’m Corey Sickles WA3UVV. Amateur Radio News And Notes: Well very good, so looking at the release here, I know they were talking about System Fusion 3 and then the new series of the DR3 repeaters. Can you tell me a little bit about that? What’s new in 3 and what can people look forward to with the new repeaters? I know a little bit more power, right? Cory Sickles WA3UVV: Uh, it is more power. Uh, the new repeaters are now available, they have dual band, dual input receivers still... compared to the DR2X, but a single transmit output and a single band. And the reason for that is that the increased power... what’s available with today’s technology for a given price point is such that it’s easier to do in a mono band configuration. So with VHF you get 85 watts out. With UHF you get 65 watts out. 100% duty cycle, full bore... that’s kind of the story of that part of things. Amateur Radio News And Notes: Well very good. So my, the club that I run this podcast through, we we use the 2. So what would be the... so obviously more power, I noticed also some new signal processing on that. Cory Sickles WA3UVV: There is. There’s a, uh, interference avoidance system, more information will be coming out about that, I don’t want to speak about it just yet. but if you have... and this is used in some commercial applications elsewhere in the world... you have interference, the repeater can switch to a different input frequency automatically AND communicate that transfer to radios... with firmware that will be upgraded at some point to do the same thing. So it would be an additional memory you’d have for this... situational kind of thing where it goes to that. Amateur Radio News And Notes: So would this be something where you’d have members of the club would sort of program it ahead of time with some sort of a key and then it would know, okay, it’s it’s time to go based on that authentication? Cory Sickles WA3UVV: Right. Right. One one example I could give of this, and it’s not the perfect one, but for my own club, we have a repeater up in the mountains. There’s a SCADA unit not too far from us. Every day at the exact same time, a gas valve opens and it puts that noise into the repeater. We once had that thing hang and it just tied up the repeater, couldn’t do anything about it other than report it to the gas company. Because we knew who the perpetrator was based on past experience. So this is something that in that scenario, the DR3 configured accordingly and the users, it would flip. Amateur Radio News And Notes: Okay. So I imagine in tight urban areas where you have a lot of, you know, you don’t have a lot of open frequencies that might be a bit of a challenge. Or or is the idea... I know they only transmit on on the band that they’re for but they do listen on both right? So would this be a situation where would it be maybe would people be moving from say VHF to UHF for the input during that time or would it... Cory Sickles WA3UVV: That is one possibility. Let’s say it’s a UHF repeater. You know, we have 30 megahertz on the 70 centimeter band. We heavily use 10 of that. Give the satellites their due. Still a lot of open room down in the 430 range... for for auxiliary inputs if you will, for something like that. So there really, you know, when we get to that band, we really don’t have the crowding of things. Amateur Radio News And Notes: Well very good. And another thing I noticed to talk about was the ASP which I know some of your newer rigs have. So would this... is my understanding right that essentially in weak signal conditions it’s going to add a level of audio processing and then that would then be boosting or taking that processed audio on the repeater output? Cory Sickles WA3UVV: Right. It’s a very current state of the art, digital signal processing for an analog signal. Uh, if you’ve had things like, uh, picket fencing, fry eggs, uh, you know the different sounds we have... It remedies that to whatever extent it needs to that technology allows. It’s a, it’s a really great thing. I mean, somebody who has used FM since the 70s and there are just certain things you just live with... we’re now at a point where we have a delivery of something where you don’t have to live with that. Amateur Radio News And Notes: Fantastic. And then in terms of the System Fusion 3 part, so what other things can people expect from the new standard? I know it’s backward compatible, right? Cory Sickles WA3UVV: Yes, absolutely. We’re we’re not taking anything away. there will be new features via firmware for certain radios. New things, you know, to come. If you remember the old Tonight Show billboard, ‘more to come’ along with that. And and some of this is is being developed. What you have right here is a working pre-production unit. It’s a real product. The firmware software things like that... later to be released to allow some of these features. Amateur Radio News And Notes: And any timelines of when when people can expect? Cory Sickles WA3UVV: Nothing that I... I I do not know. So if I were to give you a date, it

Dayton Hamvention Starts Today May 15-17, 2026 Image courtesy https://www.make-it.ca/hamvention/ Today kicks off the 2026 edition of the Dayton Hamvention at the Greene County Fair and Expo Center in Xenia, Ohio. Dayton Hamvention is the biggest hamfest in the world with last year’s attendance of 36,814 attendees. Hamvention starts Today May 15th, 2026 from 9 AM to 5 PM and continues Saturday 9 AM to 5 PM and Sunday 9 AM to 1 PM. This year’s theme is “Radio Adventure” and as always there will be a ton of vendors, tailgate sellers, and an extensive lineup of forums. Amateur Radio News and Notes on the scene in Xenia to report on the latest developments. I will be walking around on Friday and Saturday at the Fairgrounds, so If you’re going this year and see me definitely say hello.

QRPARCI Four Days in May Recap Image Courtesy https://qrparci.org/ Yesterday, Thursday May 14, 2026 the QRP Amateur Radio Club International’s Four Days in May conference took place in Fairborn, Ohio. This year there were a lot of great talks. Harold KE6TI started out the day with a talk about his journey in the world of homebrewing radios from a young novice to his career in electronics. Next up was Anthony K8ZT who reminded us that life is NOT too short for QRP with a talk that gave a lot of tips on how to succeed in QRP operations (his talk can be found at https://tiny.cc/qrptips). Then we were treated to a fascinating talk by Jonathan KM4CFT about the design philosophy of his CFT1 QRP radio that discussed his objectives and methods to create and release his popular radio. The next talk was from Thomas K4SWL about how he and his community in Swannanoa, NC dealt with the aftermath of Hurricane Helene using amateur radio and the power of community (see his coverage of at http://qrper.com/tag/helene-aftermath). His talk highlighted the resilience and resourcefulness of the community and provided some practical tips about how to be better prepared for future disasters. Jerry AC4BT had a talk about some of the methods he uses to build his CW skills. Stewart G3YSX gave a talk about how “Vibe Coding” using Artificial Intelligence is changing amateur radio with some practical examples and information. Al AC8GY and Jack W8TEE showed their clever magnetic loop antenna controller which allows for the automatic tuning of the notoriously difficult to tune magnetic loop antennas. Their result was impressive and they have released their code as open source so you can build your own. And last, but not least, Ross VK1UN showed us how he was able to design antenna tuners for the 160 meter, 630 meter, 2200 meter, and 8900 Hz bands allow him to have his QRP signals received thousands of miles away through ingenious engineering and circuit modeling. Then in the evening Ashhar Farhan VU2ESE gave a talk about his LARCSET 40 meter transceiver kits that allow builders to get on the air for around 30 dollars. The evening was capped off with vendor night, with many QRP vendors in attendance including Adam K6ARK, Packtenna, N6ARA Electronics, Halibut Electronics, Tufetln, HF Signals, Spootenna, POTA Cat, QRPMe, DX Engineering, and many more. It was a busy and fun filed day in Fairborn, Ohio. Elecraft Announces New AX4 Antenna Image Courtesy Elecraft Just ahead of Dayton Hamvention, Elecraft announced the next release in their AX line of compact antennas, the AX4. The new antenna maintains a compact form factor while allowing 100 Watts of output on CW and SSB and 50 Watts on digital modes. It is designed to be clamped to a table or bench, or put on a tripod with a 1/4-20 mount and has a longer 8 foot long whip that boasts a 6 dB gain improvement on then previous 4 foot whips. The antenna is resonant on 7, 10, 14, and 21 MHz and with the use of an antenna tuner the antenna can be used from 40 meters through 10 meters. The BL3 Balun unit keeps RF off the feedline and is an essential part of the 100 Watt power handling capacity of the antenna. The unit weights 15 oz, the main unit is 6.7 inches long and the whip is 13 inches collapsed and comes with a bag. As we go to press Elecraft has not announced a price, but they did have one on hand at FDIM’s Vendor Night. For more information about the antenna and to sign up for their wait list visit https://elecraft.com/products/ax4. Yaesu Announces System Fusion III and DR-3X Repeaters Image Couresy Yaesu USA YouTube Channel John Kruk N9UPC announced on Yaesu USA’s YouTube channel that Yaesu will be announcing the latest version of their System Fusion system, version 3 at Dayton Hamvention today. The new version is fully backwards compatible with existing radios, and details about the new capabilities in version 3 will be discussed in more detail at Hamvention today. Also announced were two new repeater systems, the DR-3XV and the DR-3XU. The V version transmits on 2 meters with an increased output power of 85 Watts and the U version transmits on 70 centimeters with an increased power of 65 Watts. The radios are rated for a continuous duty cycle and implement the new features of System Fusion III. The modulation method remains the same C4FM with automatic mode selection, but an added feature is the inclusion of their ASP (Audio Signal Processor) functionality seen in some of their newest VHF/UHF rigs which they claim will increase receive capabilities and signal intelligibility in weaker signals. They also mention a Interference Evasion System that purports to deal with intentional interference and reroute radios to an alternate frequency until the interfering signal disappears. Additional details are forthcoming at today’s Hamvention.

    In the log this week * Icom Teases X-026 Radio Ahead of Dayton Hamvention * Hamlib Wins 2026 Amateur Radio Software Award * The FCC Grants AST SpaceMobile Limited Use of 70 cm Amateur Band * MVARC Nets on the Air * What’s happening with DX? * Solar Activity Update * Upcoming Contests * Interesting Online Radio Content As always, links to all referenced content can be found in the show notes, or at our Substack at mvarc.substack.com. Thanks for reading Amateur Radio News and Notes. Subscribe for free to receive new posts and support my work. Icom Teases X-026 Radio Ahead of Dayton Hamvention Images Courtesy Icom Icom’s Japanese Facebook page teased a prototype radio to be shown at this month’s Dayton Hamvention called the X-026 in a short video. In the video a radio with what appears to be a detachable head and separate base unit is shown along with a car having two different antennas. As you can imagine, speculation online abounds, but one of the leading theories is that we may be looking at a mobile HF/VHF/UHF rig being shown in Dayton as a potential successor to the Icom 7100. The 7100 is still in production and was originally shown at the Tokyo Ham Fair in 2012 and released generally in 2013, so it may be ready for a refresh. That said, details are few, so we’ll have to stay tuned to see what develops. Amateur Radio News and Notes will be at Dayton Hamvention again this year, so we’ll make sure to give you all the details as they become available. To see the teaser reel from Icom visit https://www.facebook.com/reel/1740855356941241. Hamlib Wins 2026 Amateur Radio Software Award Image Courtesy Amateur Radio Software Award The Amateur Radio Software Award committee announced that the 2026 recipient of the Amateur Radio Software Award will be the Hamlib project. The Hamlib project allows for other software applications to access and control a wide array of amateur radio rigs and devices. The project allows for the abstraction of the control logic so other applications don’t need to know the details of each individual rig interface. Hamlib has existed for over a quarter century, but is still actively maintained by its core development team. Congratulations to the Hamlib team for this well deserved award. For more information about the award visit https://arsaward.com/ and to check out Hamlib visit https://hamlib.github.io/. The FCC Grants AST SpaceMobile Limited Use of 70 cm Amateur Band The Federal Communications Commission published its Authorization and Order DA 26-391 on April 21, 2026 authorizing AST & Science, LLC’s AST SpaceMobile service to utilize frequencies in the amateur radio 70 cm band on an emergency basis. The application to use those frequencies had brought significant pushback from the amateur radio community as the AST SpaceMobile constellation seeks to launch 248 satellites in non-geostationary orbit for the purpose of providing space-based mobile phone services with the authority to deploy 223 additional satellites. While the primary frequencies in use are the bands used by cell phones and in the SHF bands for backhaul, they requested and were given the right to utilize the frequencies of 430.5, 432.3, 434.1, 435.9, and 439.5 MHz with a bandwidth of 50 kHz in the 70 cm bands for what are termed “Emergency Operations Only” outside the U.S. only. The FCC noted significant opposition to the operation in the bands but said “AST has shown that harmful interference from AST’s transmissions to other authorized operations, including to amateur operations, in the 430-440 MHz band is extremely unlikely, and, if such interference, should occur, AST is capable of ceasing such transmissions.” The Authorization and Order continues “Regarding objections and concerns raised by members of the amateur radio community, see AST Modification Grant n.15, we have continued to not receive any complaints of harmful interference for AST’s already-authorized operations in the 430-440 MHz band. In addition, we will continue to limit AST operations in the band to emergency operations when no other bands are available for the 223 additional satellites authorized herein for a period not to exceed 24 hours. We find that this will further mitigate any possibility of harmful interference”. The full Authorization and Order can be found at https://docs.fcc.gov/public/attachments/DA-26-391A1.pdf.

Contest Spotlight: CQMM DX Contest This weekend brings the 2026 edition of the CQMM DX Contest from 0900 UTC on Saturday, April 18 (5 AM Eastern Time on Saturday) until 2359 UTC Sunday (7:59 PM Eastern Time Sunday). This contest seeks to promote unity and integration of amateur radio operators around the world, support the chase for two CWJF awards in Brazil, and to promote the art of CW around the world. To that end, it is a CW only contest on the 80, 40, 20, 15, and 10 meter bands. Although it is organized in Brazil, it is an international contest and participants are grouped by continents. Power classifications include High Power up to 1500 Watts (or local maximum power), Low Power up to 100 Watts, and QRP up to 5 Watts. Operating categories include Multi Operator-Single Transmitter All Band for HP/LP, Single Operator-Single Transmitter All Band for HP/LP/QRP, Single Operator Single Band for HP/LP, and Single Operator All Band for a station run by a YL. The rules allow for the use of DX clusters and skimmers during the contest. Contacts are considered valid when validated in both ops logs, unless the missing op is in at least 5 logs, so if you participate, it is recommended you submit a log even if just participating casually. Contacts may be made 1 QSO per band per station. When calling CQ it is recommended to to send “TEST CQMM CALL” where call is your call sign, but “CQ TEST MM” is also acceptable. For the exchange members of the CWJF will send RST + Continent + M (so for a South American station it would be “599 SAM”), non-Members will send RST and Continent (so for North American stations “599 NA”), QRP stations will send “RST + Continent + Q” (so European QRP would be “599 EUQ”), YL Stations send “RST + Continent + Y” (so a YL in Oceania would send “599 OCY”), and Multi-Op stations would send “RST + Continent + C” (so an African club would send “599 AFC”). Valid continent abbreviations are Africa (AF), South America (SA), North America (NA), Asia (AS), Europe (EU), Oceania (OC), and Antarctica (AN). QSO Points are 1 point within the same DXCC entity, 2 points on the same continent but different DXCC entity on 10/15/20 meters and 4 points on 40/80 meters, 3 Points between different continents on 10/15/20 meters and 6 points on 40/80 meters, 10 points with CWJF members and YLs regardless of location, and 3 points for Maritime Mobile /MM stations regardless of location. Multipliers include different prefixes in South America valid for all 5 bands separately, and DXCC entities valid once. Maritime mobiles don’t count as a valid multiplier. The final score is the sum of points for all bands multiplied by the sum of multipliers. Certificates will be available for all participants and plaques will be awarded for the highest score in each category regardless of continent. Logs should be submitted electronically to cwjf@cqmmdx.com in Cabrillo 3.0 format by July 30th. More information on the contest and the full rules can be found at https://www.cqmmdx.com/rules. This promises to be a fun one, so give it a try this weekend. Good luck. MFJ Sells Cushcraft and Hy-Gain Brands to ITU MFJ Enterprises announced that they have sold the Cushcraft and Hy-Gain brands to ITU corporation. Cushcraft and Hy-Gain have a long history of making antennas for the amateur radio market along with other related accessories. In May 2024 MFJ shut down on-site production at their Starkville, Mississippi facility which impacted the production of these brands products. With the acquisition of the brands by ITU the brands should return to manufacturing. ITU plans to open a production facility in Linton, Indiana that is expected to bring 20-50 jobs to to the area. All the designs, equipment, and rights for the brands were included in the sale. ITU estimates it will take about two months to move the equipment from Mississippi to Indiana.

Event Spotlight: Parks on the Air Support Your Parks Weekend April 18-19 This weekend brings Parks On The Air’s Support Your Parks Weekend. The weekend is a quarterly event which encourages operators to get out into the parks and on the air to have as much fun as possible. The excitement begins at 0000 UTC on Saturday (8 PM Eastern Time Friday Night) until 2359 UTC on Sunday (7:59 PM Eastern Time Sunday). Usually there are hundreds of operators out in the parks and lots of opportunities to get less frequently activated parks and locations in the log.

Over the last week the SFI has increased. Solar activity has been at low levels in the last 24 hours. The geomagnetic field has been at quiet levels in the last 24 hours and the Kp index reached 1 yesterday. The solar wind peaked at 355 km/s. Solar activity is predicted to be at low levels with a chance of M-class flares today through Sunday. The geomagnetic field is forecast to be at quiet to major storm levels today, at unsettled to major storm levels Saturday, and unsettled to minor storm levels on Sunday. The chance of solar radiation storms at the S1 or greater level is at 1% today through Sunday. R1 to R2 radio blackouts are possible today with a predicted probability of 30% today through Sunday. R3 or greater blackouts are unlikely with a 5% chance predicted today through Sunday. It remains a fantastic time for amateurs to get on the air and work the world.
