Going the extra mile: the radio operators who connect all 26.2 miles of the Boston MarathonEarly in the morning April 15, thousands of volunteers and athletes began to check-in and start the race that constitutes one of the biggest days in sports: the Boston Marathon. Among them were a cadre of unseen — but vital — amateur radio operators who kept a constant loop of communications for the duration of the race. More than 9,000 volunteers support the Boston Marathon every year “working in all areas including packet stuffing, medical … start line, finish line and everything in between,” according to the Boston Athletic Association, or BAA, website. Of those 9,000, around 300 are amateur radio volunteers, a position that requires a license from the Federal Communications Commission The volunteers are responsible for maintaining constant radio communications, connecting all points of the course with a main radio hub, Boston Fire, EMS and police. Fifteen members of NU Wireless, Northeastern’s amateur radio club, will be represented among the volunteers, said Garrett Compston, a third-year computer science and music combined major at Northeastern and president of NU Wireless.Many Northeastern students run in and volunteer for the marathon every year, but it was Marty Sullaway, a fourth-year electrical and computer engineering combined major, who first recruited people from Northeastern to be amateur radio operators. Sullaway, who was raised in Newton, began his journey with radio communications in 2013 when he joined a radio club in Brookline. Through that club, he began assisting race operations in the 2014 marathon. “Over the last 10 years, my very small couple hours around race day turned into hundreds of hours over a year of work,” he said. Sullaway currently serves as the segment coordinator for transportation and co-leads the technical infrastructure for amateur radio communications. Radio communications provide important assistance to the other marathon volunteers, said Jonah Lefkoff, a third-year computer engineering and computer science combined major and vice president of NU Wireless. Most of the volunteers in attendance do boots-on-the-ground work, like managing hydration stations or medical tents, but Sullaway, Compston and Lefkoff were in a control room overseeing operations. As president of NU Wireless, a position Sullaway held for four semesters beginning in the spring of 2021, he has heavily recruited amateur radio operators for the marathon from the club. The first year he advertised the volunteer position, three members came. This year, there will be 15. “The value of the marathon, to novice amateur radio operators, is it offers real world experience,” said Maggie Heaney, a third-year electrical engineering and music combined major and director of outreach for NU Wireless. “We treat [the marathon] as a good opportunity for especially younger hand radio operators to get out and use these skills to help the general populace or other outside groups such as the Boston Athletic Association.” All of the amateur radio operator volunteers from Northeastern attended a training session in Framingham in February to learn more about the marathon course and their assignment. There are four segments that radio operator volunteers can serve on: start, finish, course and transportation. Amateur radio operators are commonly used at large sporting events, Lefkoff said. During the 2013 Boston Marathon bombing, radio volunteers played a vital role in coordinating and carrying out an emergency response, he said. Although volunteer amateur radio operators predate the bombing, the BAA has integrated them more with race operations since, Compston said. The lines of communications used by amateur radio operators allow the other volunteers to focus on any runners needing assistance without having to be solely responsible for also coordinating a response. “I think that’s the value that we provide,” Lefkoff said. “Having that line of communication and taking that stress off of the other volunteers at the race course is really helpful.” A central component of being an amateur radio operator is being knowledgeable about the safeguards that are in place in case something fails or an emergency occurs. “It’s things like this where you realize that without people that are knowledgeable enough to set up the infrastructure to talk [over radio], communication would be extremely hard to come by,” Compston said. “It’s really great to see people that are highly competent and know what they’re doing with this and be able to work with them in this capacity of everyone working towards something a lot larger than what they themselves can do.” Active Hurricane Season Predicted for 2024Colorado State University (CSU) hurricane researchers predict an active Atlantic hurricane season (June 1 to November 30) in their initial 2024 forecast. ARRL Director of Emergency Management Josh Johnston, KE5MHV, attended the National Hurricane Conference in Florida in late March, where the CSU prediction was issued. "The common discussion at the National Hurricane Conference this year was the potential for a very active year, and the forecast from CSU enforces that thought," said Johnston. "Several of the forecasters were pointing to indications that we are moving from an El Niño to a La Niña and that could potentially cause a more active season." The CSU Tropical Weather & Climate Research team predicts 23 named storms during the Atlantic hurricane season. Of those, researchers forecast that 11 will become hurricanes and five will reach major hurricane strength, as measured by the Saffir-Simpson Hurricane Wind Scale, with sustained winds of 111 mph or greater. The prediction is above the 30-year average for hurricanes and storms and is above the total of 20 storms, seven hurricanes, and three Category 3 or higher hurricanes in 2023. Senior Research Scientist in the Department of Atmospheric Science at CSU and the lead author of the report Phil Klotzbach said, "So far, the 2024 hurricane season is exhibiting characteristics similar to 1878, 1926, 1998, 2010, and 2020. Our analog seasons were all very active Atlantic hurricane seasons." The team predicts that 2024 hurricane activity will be about 170% of the average season from 1991 - 2020. By comparison, 2023's hurricane activity was about 120% of the average season. The report also includes the probability of major hurricanes making landfall, including a 62% probability for the entire US coastline. The average landfall from 1880 - 2020 was 43%. The report also indicates increased landfall probabilities of 34% for the East Coast of the US, including the Florida peninsula (the average from 1880 - 2020 was 21%); 42% for the Gulf Coast, from the Florida panhandle westward to Brownsville (the average from 1880 - 2020 was 27%), and 66% for the Caribbean (the average from 1880 - 2020 was 47%). The National Weather Service (NWS), National Hurricane Center (NHC), and Hurricane Watch Net (HWN) are prepared for an active hurricane season. Amateur radio operators can take part in activations on 14.325 MHz during the day and on 7.268 kHz at night. As propagation changes, the HWN may operate both frequencies simultaneously. At the Florida conference, Johnston also highlighted the relationship between ARRL and the Federal Emergency Management Agency (FEMA), as well as ARRL's position as a net control station within the SHAred RESources High Frequency Radio Program (SHARES) managed by the Cybersecurity and Infrastructure Security Agency. "Now is the time to prepare for emergencies of any type by building relationships, training and refreshing skills, and testing and preparing equipment," added Johnston.
Handy chart.... WEEKEND EDITION: Saturday meeting and cookout at the CAARA clubhouse today, all are welcome if you are in the area...Average size of women's butts around the world revealed: US fails to crack top 5 and UK is nowhere near top... Amateur Radio Saves Family in Death Valley National ParkDeath Valley National Park is in a remote desert in southern California, where mobile phone networks are spotty at best. On Saturday, April 6, a radio amateur and his family were enjoying the park when their vehicle became stuck in mud in a dangerous area. Without access to a cell network, the ham called for help on the 10-meter band. According to a news release from the Black Swamp Amateur Radio Club, Caleb Gustwiller, KD8TGB, jumped into action. Gustwiller was monitoring from Ohio when he picked up the distress call. He was able to hear the call sign and the general location of the ham in distress. He lost the signal to the noise, so he wrote a post in the Parks on the Air® Facebook group asking for other hams to listen for the calls. Several hams contacted emergency officials in southern California, which led to the ham and their family being rescued within a few hours by park rangers. The club stated in their Facebook post: "Without Caleb hearing this distress call, it could have quickly become a very deadly situation for the operator and his family." Ham Radio Active During EclipseMillions of people across the United States got to see a rare solar eclipse on Monday, April 8, 2024. The path of totality -- the line of darkness where the moon fully occluded the sun -- stretched through the South Pacific, Mexico, central Texas, the Ozarks, the Midwest, the Rust Belt area, and to New England through the Maritimes. In all, 14 ARRL Sections were impacted directly and several more were on the fringes of the solar umbra. Radio Serves Amateur radio was active throughout the areas of impact. Most ARRL Sections in the path had been developing a plan with their served agencies for months or years beforehand. Traffic was expected to be significant, with up to 3.7 million people forecast to travel to areas within the path of totality. Radio amateurs were activated in many locations. In Paris, Texas, hams split shifts at the Lamar County Emergency Operations Center (EOC). Teams of two operators volunteered for 4-hour shifts. The activation doubled as a training opportunity and an equipment test. The ARRL Indiana Section was in full force with their Amateur Radio Emergency Service® (ARES®) member-volunteers providing radio coverage on HF, VHF, and UHF amateur bands and utilizing GMRS. Using a mobile command center dubbed "Big Blue," the ARES team in Lake County set up on an overpass above Interstate 65 and was staffed in part by father and son volunteer team Chris Lattimer, N9MMR, and Tavas Lattimer, KD9NSC. The Section also utilized Winlink VARA HF to establish a digital connection with the incident command system. In Hamilton County, Indiana, ARES members volunteered with the county emergency management teams. They fanned out across EOCs, parks, and other locations. One ARES member, who is also active in the Civil Air Patrol, monitored traffic and crowds from an airplane. Section Emergency Coordinator of the ARRL Maine Section Keith Anoe, KE4UCW, held hourly check - ins via radio with the Maine Emergency Management Agency and other served agencies in case one of them needed to activate the Maine Emergency Communication Net. Social media posts throughout the amateur radio space hold anecdotes of 146.52 MHz being extremely active during the post-eclipse traffic jam. Radio Gathers In Vermont, several ARRL members, who also happen to be pilots, gathered at the Northeast Kingdom International Airport in Newport to watch the eclipse. Outside ARRL Headquarters in Newington, Connecticut, staff members and headquarters volunteers took the opportunity to observe the 92% visible eclipse using a solar viewer built by W1AW Station Manager Joe Carcia, NJ1Q. Radio Studies Across the world, radio amateurs participated in the HamSCI Solar Eclipse QSO Party. It involved operating before, during, and after the eclipse to gather log data. Those logs will be studied by researchers in the coming years to further investigate the sun's impact on the ionosphere. HamSCI's program leader Dr. Nathaniel Frissell, W2NAF, was active from The University of Scranton Amateur Radio Club station. "I'm happy to report that we had an excellent day at W3USR in Scranton and believe that we both had fun and collected good data," he wrote in a message to the HamSCI team. The organizers request that those who operated in the event upload their logs. If you used N1MM+ or N3FJP loggers, there's a setting called Solar Eclipse QSO Party. Participants can also submit a Cabrillo or ADIF file of their activity. All logs should go to https://seqp.contesting.com/seqpsubmitlog.php. Case Amateur Radio Club gains national attention for eclipse researchIt’s not every day that a Case Western Reserve University student organization gets interviewed for News 5 Cleveland or Smithsonian Magazine. But for the Case Amateur Radio Club, which goes by the call sign of W8EDU, national press coverage was only a part of their lead up to the eclipse. In their day-to-day operations, W8EDU is a place for undergraduate students to engage with amateur radio, commonly referred to as ham radio, to send and receive messages for a non-commercial purpose. Tucked in a shack on the roof of Glennan Building, W8EDU members are taking ham radio to another level, using its capabilities to make scientific discoveries. Benjamin Nelson, a fourth-year electrical engineering major and W8EDU’s historian, said, “It was my introduction to amateur radio and a lot of electronics initially in my undergraduate. And from there, it kind of became this whole social thing, nice to hang out with people on Thursday nights, do cool radio physics and electronic stuff. And then over time, it kind of grew.” One of his favorite memories was a time he was using a digital interface, known as FT8, to communicate with individuals outside of North America. He said, “We ping[ed] someone in South America and Europe at the same time and it was like, oh my gosh, we’re sending signals and communicating with them.” Recently, the organization made campus headlines for their game of radio chess against The Ohio State University during the homecoming festivities at the start of the academic year, which was highlighted by the American Radio Relay League and other campus newspapers. Part of the way they do this is by holding licensing exams on campus where community members can be authorized by the Federal Communications Commission to operate amateur radio in the United States. Nelson mentioned how much the amateur radio club expanded in terms of active members and the number of licensed radio operators at CWRU. “The eclipse is this magical thing for amateur radio because it completely messes with the ionosphere,” Nelson said regarding why the eclipse is such a big deal for amateur radio operators in the United States. He later explained that the ionosphere, which is a layer of the atmosphere, is vital for amateur radio as it is “the reason why radio waves when we send them off don’t just fly off into space, they can bounce back and reflect.” The ionosphere is the space where the atmosphere meets space, and it is where all of Earth’s charged particles are located. It is known that ultraviolet radiation from the Sun induces changes to the ionosphere, and W8EDU members, in collaboration with other North American amateur stations, wanted to understand the recombination time of the ionosphere during the rapid fluctuation of the eclipse. “[The Eclipse] provides a really interesting environment for us to examine the ionosphere by sending signals, transmitting, receiving and seeing how the radio waves we send out behave differently under normal circumstances,” Nelson said. The ionosphere is important for radio operators because sudden changes to the ionosphere are thought to affect communication systems. To test this theory, W8EDU and other local stations monitored the reception of the Canadian time standard station CHU before, during and after the eclipse. “It’s a standard signal, it’s always the same, you know what it’s going to be exactly, so you’re able to see the deviations as they happen in real time,” Nelson said regarding why they used this method of data collection. This research project has since caught media attention from outlets such as The Washington Post, Smithsonian Magazine and The Wall Street Journal. This media attention shows that this is no longer just an effort from a club at CWRU, but it has become a global initiative, involving operators from the United States, Mexico and Canada. Nelson said, “What we’re doing is we’ve sent some receiving kits and given instructions out to a whole network of amateur radio operators and citizen scientists who want to help out.” A week prior to the eclipse, W8EDU had signed up 50 of these operators. Nelson and his colleagues mentioned that this is uncharted territory for amateur radio operators: “I think people may have done some sort of experiments to try and estimate [the effect of the eclipse on the ionosphere].” For Nelson and rest of W8EDU, the eclipse provided the ultimate opportunity for “people with [a] really niche interest in amateur radio to come together on this whole big project … It’s been really neat seeing not just outreach but how much support we’ve gotten from other students which has been really cool.” Tyler Zupfer, a second-year polymer science engineering student, stated how they “think it’s super cool that radio gets a chance to do research in such a once-in-a-blue-moon event.” During the eclipse, many members were excited by the potential application of radio. As such, select W8EDU members got to experience the eclipse from the roof of Glennan Building. Staff from the university’s marketing department were also present on the roof, broadcasting a livestream of the view. Nelson said that the eclipse experiment would be “pretty automated,” which allowed members to watch the eclipse themselves. Nelson noted that right after the eclipse came, it felt “surreal,” and many shared this sentiment. Just after totality had passed, the entire roof erupted in a sense of feverish excitement, with individuals shouting, “this must be fake” and “space is so cool.” For many individuals, including fourth-year electrical engineering student and President of W8EDU Adam Goodman, part of the fun was seeing their research projects and questions come to life. He noted that a highlight for him was “to see the data come in real time and celebrate that.” “To view it from the roof with my friends, the alumni, the faculty and so many guests made it a special experience for us,” Goodman said about the community he and other amateur radio operators at CWRU have built up. Eclipse day for W8EDU was about more than just running experiments. It was also an opportunity to engage in contesting, where each station attempted to contact as many other stations during a set period of time—in this case, the hours preceding, during and after the eclipse. Nelson explained that this is called a “QSO party which [is held] around the eclipse.” He said, “This isn’t led by W8EDU, this is a more general amateur radio thing. It’s kind of a big contest where everyone’s going to be trying to make a bunch of contacts here and there.” For those in W8EDU, this became known as the “Tinktenna” Crew after the installation of a large radio antenna on the balcony of Tinkham Veale University Center. Starting in the morning and proceeding once the eclipse passed, operators attempted to make as many contacts as possible by exchanging basic name and geophysical information with those on the other side of the receiver. Aaron Bilow, a first-year electrical engineering student, was one of the individuals responsible for making contact with the other mature radio operators. At the start of the eclipse, he said, “We’ve made contacts so far in Florida and Washington State, and we are just doing a great job of connecting the community as a whole in terms of eclipse research and just this hobby that we all love.” The crew on the “Tinktenna” reported getting in contact with 19 other operators, such as ones from Puerto Rico. While those operating the radio were either qualified operators, many students with no prior experience came to witness the antennas. “It’s very cool to be part of this historic citizen science project,” second-year biology student Matthew Haimowitz, who previously had minimal involvement with the amateur radio, said. “And I’m sure even though I’m not an engineering major, I’m sure this will not be my last interaction with the radio club.” FRIDAY EDITION: Raging wind and rain here in the island, should stir up the lobsters.

When we think of a spark gap radio transmitter, most of us immediately imagine an early twentieth century ship’s radio room or similar. Most of us know these transmitters as the first radio systems, and from there we’ll probably also know that they were phased out when better circuits arrived, because of their wide bandwidth. So it’s rare in 2024 to find anyone characterizing a spark gap transmitter, as [Baltic Lab] has. The circuit is simple enough, a high voltage passes through an RC network to a spark gap, the other side of which is a tuned circuit. The RC network and the spark gap form a simple low frequency relaxation oscillator, with the C being charged until the spark gap triggers, forcing the subsequent discharge of the capacitor and causing the spark to extinguish and the cycle to repeat. The resulting chain of high voltage pulses repeatedly energizes the tuned circuit, with each pulse causing a damped oscillation at its resonant frequency. The resulting RF signal is a crude AM tone which can be received fairly simply. The mathematics behind it all is pretty interesting, revealing both the cause of the bandwidth spread in the low Q factor of the tuned circuit, and the presence of a large spurious frequency spike on an interaction with the capacitor in the RC circuit. It’s all in the video below the break, and we have to admit, it taught us something about radio we didn’t know.

Utah students use ham radio to connect with astronaut during eclipseThe solar eclipse might not have been fully visible from Utah, but that didn’t stop a group of Tooele students from having an astronomical experience on Monday, when they interviewed an astronaut aboard the International Space Station as it passed over Utah. Students in the Tooele County School District were able to communicate with Matthew Dominick, a NASA flight engineer on Expedition 71 on the space station, through the Amateur Radio on the International Space Station program. The international program coordinates radio contact events for classrooms and communities to learn more about life in space and practice using communication and radio technologies. Teachers and students gathered in Tooele’s Community Learning Center, which houses the district’s career and technical education programs. Members of the Logan-based Bridgerland Amateur Radio Club provided tech support for the event, which included constructing an antenna system on the center’s roof in order to connect to the space station. The call started when the International Space Station was positioned above Utah, around 11:45 a.m. MDT. Clint Thomsen, the teacher who coordinated the event, switched on his radio and called out to the space station, which orbits around 250 miles above sea level. The crowd heard only static at first, but astronaut Dominick’s voice finally crackled through the auditorium’s sound system. Students quizzed Dominick on his training to become an astronaut, the physical effects of being in space, how zero gravity would affect the flight of a paper airplane, what movie nights are like on the space station and whether there is a procedure in place for alien contact (Dominick said there isn’t). Dominick also shared some interesting anecdotes from his life in space. One student asked what it was like to cry in zero gravity, and although Dominick reported he hadn’t yet had “a really good cry” in space, he said another astronaut had recently experienced something similar. “The other day a friend of mine had some chili pepper in her eye, so we took a drink bag, squirted water out and filled up her eye socket with water, and it stayed there,” Dominick said. “It doesn’t run down her face, it just stays in her eyeball. It’s kind of fun to see, so I would imagine tears would just well up and create a giant ball of water in your eyeball.” Dominick encouraged the students to find their niche in space exploration and pursue subjects they love. “If you find out what you’re passionate about, you’ll do a much better job at it,” he said. “If you go do something you love, at the end, you’ll be so much better at it ... and we need all kinds of people with all kinds of talents up here to (work) from a diversity of backgrounds to make it go farther.” Chaston Williams, one of the students who spoke with Dominick, said one of the best parts of the experience was connecting with the astronauts over their shared interest in radio technology. TUESDAY EDITION: Red Sox home opener has nice weather for a change....I set up a LDG 100Pro2 tuner with the new FT710. Unlike using it with the Icom 7300 where the radio goes in tune mode at reduced power, the FT710 radio tune button does nothing. You must manually turn power down to 10 watts and push the tune button on the tuner, you think Yaesu would want to make life easy! The fan does turn off once in a while, I thought it ran continuosly at first. It still runs to often when just in receive mode....overall, a nice radio....I hear a lot of chatter about the new Mercury hf amplifiers, very expensive and a one year wait time to get them. A watt is a watt, I guess if you have the money to burn.... Solar eclipse signals opportunity for Parkersburg Amateur Radio KlubPARKERSBURG — Today’s solar eclipse and its effect on radio signals will be studied at Parkersburg South High School in a collaboration with the Parkersburg Amateur Radio Klub. A ham radio station will be set up from 12:30-4 p.m. in front of the school.
The Parkersburg South science department has coordinated the demonstration with Conard Richardson, the radio club’s vice president of technology, and Alex Cantu, a retired Air Force lieutenant colonel and the senior Instructor of Parkersburg South Air Force Junior ROTC, who will conduct the demonstration. Cantu also is a recently licensed ham radio operator. “We will have ham operators there to explain what we’re doing, in addition to helping anyone interested in becoming a ham,” Larry Dale, a member of the radio club, said. The results taken during the eclipse will be reported to the National Aeronautics and Space Administration through NASA’s Citizen Science Program. NASA, which has encouraged ham radio operators for help in some science experiments, and the Ham Radio Science Citizen Investigation group are encouraging ham radio operators across North America to help in this rare opportunity. The public is encouraged to attend, Dale said. The event will be held in the front of the school on the lawn, he said. “It’s going to be the last one here in the United States for what, 20 years,” Dale said. While visibility is impacted by the weather, the solar eclipse in this region will start shortly before noon and end around 4:30 p.m. The peak will be around 3:15 p.m. with about 95% totality, according to the National Solar Observatory. A solar eclipse occurs when the moon is between the sun and the earth. The sun’s corona is visible at totality. After today’s activities, the radio club will hold its monthly meeting at 6:30 p.m. at Western Sizzlin’ Steakhouse, U.S. 50 and W.Va. and 68. Information will be available about how to become a ham radio operator. Measuring solar eclipse impact on Ham radios in ScrantonSCRANTON, LACKAWANNA COUNTY (WBRE/WYOU) — Science students at the University of Scranton are getting a once-in-a-lifetime lesson Monday. Through NASA-supported research, students are looking at how the solar eclipse impacts radio waves. At the university’s state-of-the-art ham radio studio, there was lots of activity there. Students say it’s an incredible learning opportunity. The studio was built in the fall of 2023 through an Amateur Radio Digital Communications (ARDC) grant awarded to Doctor Frissell, who is leading Monday’s research with students and ham radio They’ve been collecting data of changes in the earth’s electrically charged upper atmosphere that occur during the eclipse. This project is called the HAMSCI Solar Eclipse QSO party, and it’s one of just five projects selected by NASA for the study of the total solar eclipse. “We have a lot of great guests here, a lot of traction at the university. It’s a really great opportunity to gather data because of the amount of coverage we are getting for this eclipse,” said University of Scranton electrical engineering student Thomas Pisano. Students will be here working until 8:00 p.m. Monday. Hamming it up at the eclipse (New York)nside the Adirondack Sky Center and Observatory’s Roll-Off-Roof-Observatory on Friday, amid an auditory cloud of radio chatter, machine tones and static hum, Marc Staves picked up his ham radio mic and spoke into it. “Whiskey. Alpha. Two. Echo. Whisky. Yankee. WA2EWY club station,” Staves said. After giving his location in Tupper Lake to the net controller, he told people listening from around the East Coast about how amateur radio operators in the Tri-Lakes are preparing for the April 8 total solar eclipse. Tupper Lake is just south of center in the path of totality. While they take in the rare sight of the moon blocking out the sun, Staves said they will also be capitalizing on the rare chance to study a total solar eclipse’s effects on the Earth’s ionosphere and providing that data to researchers at universities and NASA.

Peter Fairlie's Meshtastic High-Altitude Relay Station Aims to Extend the Reach of His Home NodeTaking advantage of the mesh nature of Meshtastic, this simple relay station uses two directional antennas with a radio each.Radio ham and maker Peter Fairlie has been experimenting with Meshtastic, the open source decentralized mesh communications network platform, in order to improve reception — by building and deploying a high-altitude relay station. "I got to tell you, Meshtastic's been actually pretty incredible," Fairlie says of his initial experimentation with the platform, using a roof-mounted omnidirectional antenna. "You won't believe all the people I'm getting right now. Even got a guy that was about 70km [around 44 miles] away."
hat's a decent long-range reception, but Fairlie was looking for more — and set about turning two Heltec LoRa 32 V3 boards into a relay station. "The idea here is to set two of these up on the tower," Fairlie explains. "One is going to point down towards Toronto, and the other one is going to point the other way — and these two radios will mesh with the current radio." The Meshtastic platform is well-suited to such a relay station design: the firmware loads onto low-cost off-the-shelf radio hardware and turns them into nodes in a mesh LoRa network, with the ability to then connect other devices via a given node over Bluetooth, Wi-Fi, or USB connectivity. Rather than having to pick up, amplify, and retransmit an analog signal, then, Fairlie's repeater is fully digital — acting as two distinct nodes in the mesh, one offering a strong link to Fairlie's home setup and the other targeting Toronto and further afield. "I've got two directional sector antennas on each side," Fairlie explains of the relay's design. "Each one is connected to a Meshtastic Heltec [V3], and basically this makes a long range repeater station. Whatever is coming in one end would be, through the mesh, relayed out to the other and vice versa." The project is detailed in full in the above video, and on Fairlie's YouTube channel.
WEEKEND EDITION: Another shitty day on the island, damp and cloudy. The Club is providing communications for a YuKan Run 5K race today in Gloucester. I'm glad I will be in a warm truck as the runners pass by.... Ham Radio's Many Roles During Solar EclipseIn one of nature's most spectacular visual displays, on April 8, 2024, the sun will align with the moon and the Earth, casting a shadow that will transit much of North America. Spectacular Display and Gathering Millions will gather along the path of totality - the section where the sun is fully blocked by the moon - to witness something that happens, on average, once every 375 years for any place on our planet. The moon's shadow path will begin over the South Pacific Ocean, and then it will cross into North America, passing over Mexico, the United States, and Canada. Weather permitting, the first location in continental North America that will experience totality is Mexico's Pacific coast, at around 11:07 a.m. PDT. The shadow will exit continental North America on the Atlantic coast of Newfoundland, Canada, at 5:16 p.m. NDT. Ham radio will be there - operators will participate in scientific experiments, serve local communities that will be overrun with hundreds of thousands of visitors, and provide a valuable tool for communicating if the mobile phone networks become overloaded. Science Regular sun and moon watchers will be out in force while many scientists, astronomers, and amateur radio operators will be "working" the eclipse. ARRL has partnered with Ham Radio Science Citizen Investigation (HamSCI), a NASA citizen science project, to encourage hams to send and receive signals to one another before, during, and after the eclipse. The project will be led by Nathaniel Frissell, W2NAF, a professor of Physics and Engineering at the University of Scranton in Pennsylvania. HamSCI participants will share their radio data to catalog how the sudden loss of sunlight during totality affects their radio signals. All radio amateurs are welcome to participate in the ionospheric research that is being conducted. Information is available at the Solar Eclipse QSO Party on the HamSCI website. NASA plans to point a large telescope at the eclipse and broadcast the entire event across North America. The agency will host live coverage of the eclipse from 1:00 to 4:00 p.m. EDT (17:00 to 20:00 UTC) on April 8 on the NASA YouTube channel. There will be live views of the eclipse from watch parties across the country, and even from NASA's Glenn Research Center in Ohio, which happens to be inside the path of totality. In addition to NASA's plans, the Super Dual Auroral Radar Network (SuperDARN), a collection of radars located at sites around the world, will bounce radio waves off of the ionosphere and analyze the returning signals. Their data will reveal changes in the ionosphere's density, temperature, and location. There is also the Radio JOVE project, which is made up of a team of citizen scientists dedicated to documenting radio signals from space, and especially from Jupiter. During the total solar eclipse, Radio JOVE participants will focus on the sun. Using radio antenna kits that they set up themselves, they'll record solar radio bursts before, during, and after the eclipse. EmComm Emergency communications groups, including those affiliated with the Amateur Radio Emergency Service® (ARES®), will be active in the areas near totality. National Weather Service (NWS) offices are closely watching weather patterns in and around the eclipse path for any severe weather that could impact watchers and increase traffic. Many first responders, including law enforcement, medical personnel, and fire departments, will be ready to respond to any emergency that might occur during the eclipse. Those officials represent some of the served agencies that radio amateurs work to support. Most ARRL Sections within the path of totality have been working with their local served agencies to provide communications volunteers through amateur radio. In New Hampshire, for example, where cell phone and road networks are expected to be overwhelmed, New Hampshire ARES has local groups activated in many communities. Public Information Coordinator of the ARRL New Hampshire Section Skip Camejo, AC1LC, said members across the state are ready. "A small team pulled from several NH-ARES groups will be providing limited communications support for the American Red Cross, using both HF and VHF. We will have an RV-based station in Lancaster, NH, and another in Pittsburg, both at locations provided by the New Hampshire Department of Transportation," he said. In the event of a mass-casualty incident or a need for emergency sheltering, the teams will travel to the scene with a state police escort. They're expecting 10,000 to 50,000 visitors on Monday in that community alone. Other ARES groups have been preparing and drilling over the last few months. In the ARRL North Texas Section, a set of criteria has been established as reportable to the local served agencies' emergency operations centers. Look for more details on ham radio involvement during the eclipse in next week's The ARRL Letter. Outreach Many groups are holding eclipse festivals. Some amateur radio groups and clubs are taking advantage of these gatherings to get radio in front of the curious public. Vice Director of the ARRL Hudson Division Ed Wilson, N2XDD, is preparing an informational display for an event at his local library. The Suffolk County Radio Club on Long Island, New York, will be participating in the Solar Eclipse QSO Party from the Moriches Branch Library. Wilson saw radio as a perfect addition to the library's eclipse activities. "Another club member and I went down to the librarian and spoke to her about the HamSCI event. We asked if we would be able to set up a ham radio station during the course of the day. They loved the idea and approved it, and they invited us to some other events that they're having in the next few months," he said. For clubs that may have a public presence during the eclipse, there are resources on the ARRL website detailing how to help explain the hobby to the uninitiated. The total solar eclipse will be the last of its kind for more than two decades in the contiguous U.S. The next total solar eclipse on U.S. soil won't occur until March 30, 2033, and it will be viewable only in Alaska.

Harnessing the 2024 Eclipse for Ionospheric Discovery with HamSCIAs the total solar eclipse on April 8, 2024, draws closer, a vibrant community of enthusiastic amateur radio operators, known as “hams,” is gearing up for an exciting project with the Ham Radio Science Citizen Investigation (HamSCI) group. Our goal is clear and ambitious: to use the Moon's shadow as a natural laboratory to uncover the intricacies of the ionosphere, a layer of Earth’s atmosphere crucial for radio communication. This rare event offers an unmatched opportunity to observe the ionosphere's response to the temporary absence of solar radiation during the eclipse. HamSCI, a collective of citizen scientists and professional researchers, plans to seize this opportunity by conducting radio experiments across North America. Our mission centers on two main activities: the Solar Eclipse QSO Party (SEQP) and the Gladstone Signal Spotting Challenge. For the SEQP, amateur radio operators across the continent will aim to establish as many radio contacts (called QSOs) as possible before, during, and after the eclipse, creating a lively scene filled with radio signals. This effort will generate a vast network of observations on radio wave behavior under the eclipse's unique conditions. The SEQP, a competitive yet friendly event, encourages wide participation and adds an element of excitement. The Gladstone Signal Spotting Challenge, named in honor of ham radio operator Philip Gladstone for his significant contributions to radio science, adopts a focused approach. Participants will use special equipment to monitor select radio frequencies, aiding in our observation of the ionosphere's reaction to the eclipse. This crucial aspect of our project validates scientific models of the ionosphere and enriches our understanding of its interaction with solar radiation. Amateur radio enthusiasts of all backgrounds and skill levels are invited to join these events, united by a shared enthusiasm for scientific exploration and a collective curiosity about the upper atmosphere. Through the support of the amateur radio community, HamSCI demonstrates the profound impact of citizen science in contributing to our scientific knowledge. As the eclipse ends, our analytical work begins. We will delve into the collected data, interpret it, and publish our findings. These efforts are expected to significantly advance our understanding of the ionosphere and showcase the value of community involvement in scientific discovery. HamSCI is an organization that aims to inspire wonder and encourage people to participate in scientific discovery. The community of citizen scientists associated with HamSCI believe that the seamless fusion of science and amateur radio is an excellent example of what can be achieved when people come together, driven by curiosity and a passion for exploration.

THURSDAY EDITION: I have a vet appt. at 930 for the dog, first chance to try out the 4 wheel drive in the F250.....it's blowing 50mph steady here on the rock, 1 inch of ice and snow mix, slippery dricing condition...sea foam at the beach!...no ham news yet,,,
cheap DMR radio... WEDNESDAY EDITION: I found the problem with the Astron power supply, I am embarrassed. The problem I was having was the Icom 7300 was not showing full power out, about 81 watts on my external meter. I thought it was the radio but put another power supply on it and sure enough it put out 100 watts. So I "assumed" the power supply or short power lead I made with a anderson powerpole connector might be the issue. I put the Fluke meter on the supply and it read only 11.6 volts at idle. The Astron meter said 13.5 volts....oh yea, a while back the voltage reading was low so I assumed all is well and adjusted the Astron meter to read 13.6 or so. My mistake! On the side of the power supply there is a screw to adjust the voltage, I turned it up to read 13.8 on the Fluke meter and then adjusted the Astron meter to the same. What was happening was the Icom kicked back power and even shut off some times when I tried to run the radio at 100 watts on 11 volts....lesson learned, check the voltage on your power supplies with a real meter, never assume anything.....Overall a nice power suply but the leds in the two meters are two bright, they look like two headlights when I go in the radio room, another project?

Any band/any mode (except the WARC bands) Students to Talk to International Space StationA group of lucky students will have the opportunity to chat with an astronaut on the International Space Station on Wednesday, thanks to a program facilitated through Embry-Riddle Aeronautical University. Five middle schools will be represented in the conversation, which will be held with NASA astronaut and current ISS occupant Matthew Dominick. The exciting interaction is part of the Amateur Radio on the International Space Station program, which connects ISS astronauts with students using radio technology. Organizers chose ERAU as a participant for the 2023-24 school year, giving the school the chance to bring in students from Volusia County to join in. The participating students have already been learning about the technology being used and about the program in the months leading up to their chat. They'll finally get the chance to talk to Matthew Dominick as the ISS passes over Central Florida at 11:22 am on Wednesday. At speeds of around 17.5k miles per hour, the ISS does a full orbit of the earth approximately every hour-and-a-half. Other 'educational contacts', as the program describes them, are held through the radio program with students across the globe. The next chats after the ERAU one on Wednesday cover such locations as Russia, France, and Italy. Astronaut Matthew Dominick joined NASA in 2017 after ten years in the United States Navy. He is one of seven crew members currently aboard the ISS, having launched on March 4th as part of a SpaceX flight. His career experience includes over 1,600 hours of flight time, 400 carrier-arrested landings, and 61 combat missions, according to his NASA profile.
TUESDAY EDITION: No radio yesterday, I spent the day with the yl enduring more tests....today I have a nice Astron 35 amp switching supply that is malfunctioning, not that old. I guess that will be the project of the day... Amateur operators of ham radios chase storms, offer serviceThey were once a vital means of communication around the world, until telephones and then the internet arrived – but they still offer public service, while having fun interacting with one another. They’re ham radio operators, and April 18 is World Amateur Radio Day, celebrating an occasion in 1925 when the International Amateur Radio Union was formed in Paris. The theme for 2024’s event, set for April 18, is “A Century of Connections: Celebrating 100 years of Amateur Radio Innovation, Community, and Advocacy.” Bill Schiller lived in Tahlequah for 31 years and worked as a professor of psychology at Northeastern State University. After he retired 10 years ago, Schiller moved to Colorado, but is planning on moving back to Tahlequah soon. “I’ve been a licensed [operator] since 1961 when I was 15 years old. I could talk to Europe and Africa before there was even a transatlantic telephone cable,” Schiller said. “It’s still a hobby of mine.” Schiller said there are “ham radio nets,” and before the internet and email, hams used to handle messages for folks needing to contact people in places where no phones were available. “In high school, during the Vietnam War, we would set up in a major department store in Pittsburg, Pennsylvania – where I lived at the time – and people would fill out radiograms and via radio, get those to Vietnam, Germany – the troops over there,” Schiller said. “There are still local nets with a bunch of people from Arkansas and Tahlequah and Missouri, and I still get on there.” The group meets at 11:30 every weekday and handles messages back and forth. “When [Hurricane] Katrina hit New Orleans, I was on the radio and some people from there were trying to get a message through to Chicago and it got routed through to me. I was able to get a message through to their relatives that they were OK,” Schiller said. Schiller was a storm spotter in Cherokee County in disaster management and would coordinate via radio with the Tulsa weather service. “In Colorado, it is used mostly for search and rescue in the mountains because there is no cell service up in these mountains,” Schiller said. Gary Way lives in Pottawatomie County, Oklahoma, and he’s a member of a local radio club in Shawnee. “There’s something about picking up a radio and talking into an antenna you built and speaking to somebody in Tokyo,” Way said. “Once, I was talking to a London cabbie and he was telling me the hardest parts about his job.” Way is in the emergency management aspect of the hobby and does storm spotting. “We do ‘after the event’ communications,” Way said. “It’s like we always say, ‘When everything else doesn’t work, we still talk.’” After a tornado hit Seminole, Oklahoma, the Oklahoma Department of Emergency Management sent the club members to help with the clean up because the telephone system wasn’t working, Way said. “We put one person with each work team, another person with the radio and somebody running notes to city management to keep them updated,” Way said. How storm spotting works is, an operator speaks to a “repeater” and the machine repeats it out over the air. Those in cars doing the spotting can communicate back to the repeater, Way said. “Anybody with a radio can tune into that frequency and can find out what’s going on,” Way said. The repeater transmits about 20 milliseconds behind the person speaking, and it sounds like real time, Way said. “The only problem is, it’s a huge footprint and so there are a zillion people listening. So you have to be selective on what you talk about,” Way said. “In the event of a storm, we are trained through Federal Emergency Management Agency that if you have a fatality, you don’t tell there is a fatality at a certain address.” The Shawnee club has been around for 76 years. Way got interested in radios 20 years ago because he hurt his back and it was easy to get into, Way said. “Radio operators tend to be service oriented,” Way said. “We have a group that works independent of Pottawatomie County emergency management and Shawnee emergency management.” The neatest thing about his experience with the radio club was working with Tecumseh High School’s technology department and making arrangements for the students to talk with the International Space Station, Way said. “We learned how to do tracking programs so we could keep the antennae aimed at the satellite,” Way said. “On the third try, we were able to talk with them and the kids got to ask questions of the [astronauts], and it was fun.” Gary Courtney said on the TDP Facebook page that there are requirements before a person can become a ham operator. “You must study for, and pass, a Federal Communications Commission test in order to legally use a transmitter. Upon passing the test, you will receive your license and unique call letters of your short wave station,” Courtney said. “You will also be expected to follow a strict protocol – and manners – while on the air.” On April 18-19, radio amateurs are invited to take to the airwaves to enjoy “our global friendship with other amateurs, and to show our skills and capabilities to the public,” states the National Association for Amateur Radio site. Monitoring the Moon when it happens: Ham radio scientists to monitor eclipse
Amateur radio

to test how far
radio messages
can go
CLEVELAND — The upcoming eclipse offers all sorts of opportunities for us to discover more about how our universe works. While many will watch the Moon and Sun share the spotlight that day, some students at Case Western Reserve University are focused on the space between, specifically the hundreds of miles far above the clouds but below outer space known as the ionosphere. Members of the Case Amateur Radio Club, known as W8EDU, are among those across the country and the globe set to test what happens when the Moon gets in the way of the sun and how that impacts (or doesn't) radio communications. It's all a part of the Ham Radio Science Citizen Investigation known as HamSCI. As W8EDU President Adam Goodman explained, the ionosphere is the stretch of the earth's atmosphere where GPS and radio signals travel and can be difficult to study. "It’s too high for planes to go but too low for spaceships to be in there," the fourth-year electrical engineering student said. "It’s this very awkward area." Goodman explained that ham radio enthusiasts are set to communicate with each other during the eclipse to see just how far radio messages can travel during an eclipse. "We just got so lucky with this experiment," he said. "We’re going to see who can receive signals at what time and therefore be able to study does the eclipse increase our ability or decrease our ability [to transmit and receive messages]?" "There’s this mysterious layer around the Earth that allows us to hear people around the world and we don’t know how it works 100% and we’re going to learn new things about it from this research," electrical engineering master's student Maris Usis added. Totality for the solar eclipse is slated to begin a little after 3 p.m. on Monday, April 8. Those in the club admit they're not sure what to expect during the experiment and once all the data is gathered. "That’s part of the fun," applied mathematics Ph.D. student Rachel Boedicker said. "That’s why we do science. Studying the ionosphere tells us more about that communication channel and this is a good time to do that because we have one isolated event we can control." MONDAY EDITION: We had a great Easter day, great meal, a healthy family, and warm enough to sit out out the deck and suck in some vitamin D....
I got the monitor hooked up last night, I notice the fan runs a lot on the ft710 on RX. I guess a common complaint. EASTER EDITION: I ordered a ft710 on Friday before noon and got it the next day before noon, amazing delivery from Dave up at HRO in Salem, NH. I played with the receiver today and the bands were very busy on 10-20 due to a contest but I played with the settings and got it sounding pretty good. tomorrow I will set up a tuner with it and adjust the TX side of the radio. If amazon shows up Sunday, I will have the cable I need for the monitor and I will give that a whirl...my wife is going to flip, a station in every bedroom...

Newsline Report SIERA hosts Scout amateur radio merit badge dayBoy Scouts talked to amateur radio operators as far away as Puerto Rico and Arizona during a radio merit badge class hosted by the Southernmost Illinois Emergency Radio Association (SIERA). Five scouts from Troop 2007, out of St. Thomas More Catholic Church in Paducah, attended the class on Saturday, March 23, at Trinity Church in Metropolis. Scouts experimented with tuning forks and a wave generator and had the opportunity to talk on both handy-talkie and high-frequency base radios during the class. They also learned about the science and mechanics of radio as well as important safety measures. Club members explained that in the event of an emergency, cell phones might not work, but ham radio operators can send and receive important messages. Club members also help out the community by staging at events such as the annual River To River Run, where they can radio for help if a runner needs assistance, even in areas where cell phone signals struggle to get out. SIERA member Lloyd Baker, who is also a Cub Scout den master, taught the class. Other SIERA members participating were president Jay Smock, vice president Aidan Carnes, secretary Geoff Williams and youth member Drew Byrne. Byrne is also a member of the scout troop. Other scouts participating were William Babbs, Cole Shoulta, Javier Bautista and Matthew Scarpino. For more information about SIERA or to arrange for testing for an amateur radio license, ws1era.org.

Watch out, Baofeng; there’s a new kid on the cheap handy talkie market, and judging by this hardware and firmware upgrade to the Quansheng UV-K5, the radio’s hackability is going to keep amateur radio operators busy for quite a while. Like the ubiquitous Baofeng line of cheap transceivers, the Quansheng UV-K5 is designed to be a dual-band portable for hams to use on the 2-meter VHF and 70-centimeter UHF bands. While certainly a useful capability, these bands are usually quite range-limited, and generally require fixed repeaters to cover a decent geographic area. For long-range comms you want to be on the high-frequency (HF) bands, and you want modulations other than the FM-only offered by most of the cheap HT radios. Luckily, there’s a fix for both problems, as [Paul (OM0ET)] outlines in the video below. It’s a two-step process that starts with installing a hardware kit to replace the radio’s stock receiver chip with the much more capable Si4732. The kit includes the chip mounted on a small PCB, a new RF choke, and a bunch of nearly invisible capacitors. The mods are straightforward but would certainly benefit from the help of a microscope, and perhaps a little hot air rework. Once the hardware is installed and the new firmware flashed, you have an HT that can receive signals down to the 20-meter band, with AM and SSB modulations, and a completely redesigned display with all kinds of goodies.
