Surrounded by the green grass tranquility of Hot Springs State Park, a temporary ham radio antenna reached into the sky. Here, amateur two way radio operator Casey Freund sat in the shade at a park picnic table along with his ham radio, laptop and portable DMR ameteur radio. He was ready to communicate on a device that had its start more than 100 years ago, and was essential to civilization before Wi-Fi and smartphones. “There are calculations you can do to find antennas that work on multiple frequencies, but they're a little harder to build yourself,” Freund said. “This is a super easy antenna that took me about 15 minutes to build last year and I measured off the piece of wire that we're using today to be harmonic to the radio frequency that we're going to be on.” Plugging his radio and laptop into his battery pack, a homemade system housed in a plastic ammo box, Freund was now ready to “key up” which means “to transmit” in ham radio jargon. Carefully fine tuning his radio, Freund checked various walkie talkie frequencies for a clear channel catching bits of conversations. He paused on one conversation which sounded like a long-distance tailgate party as the men discussed eating crackers and drinking wine from the back of their pickup truck. “There are a lot of random conversations going on in nets,” Freund explained using another ham radio term. For the uninitiated, “net” is an on-air gathering. Freund doesn’t have the capability to join the 80-meter Cowboy Net since his antenna is a smaller 20-meter set-up. However, his favorite parts of the hobby are not the conversation. He prefers to ‘CQ’ which means that the radio operator is calling out for anyone to respond for a quick contact. Freund would then log their signal strength, location and call sign into his laptop. Freund adjusted the dial on his radio transceiver, still searching for a clear frequency. He set up his antenna and gear purposely in the Hot Springs State Park in Thermopolis so he could participate in his favorite program called “Parks On The Air”. “You are trying to get as many people as you can in a short period of a time,” Freund said. He continued to move his dial in search of a clear frequency. Static, clicks, beeps and voices reminiscent of Star Wars characters came over the airwaves. “It's like a contest, a little game,” he said. The conversations are quick. Every state or national park has an identifying park number assigned to it and for Hot Springs State Park the number is 3299. This system allowed the operators to exchange their call signs, signal strength, location and radio call sign before moving on to the next person. “We call it a handshake,” Freund said. “I hear you. You hear me. Here's your signal report. Here's my signal report. How well you're hearing everything. And then the park numbers. It’s a lot of trying to make as many contacts as quick as you can.” Freund paused on a static filled frequency and called out, “CQ, CQ is this frequency in use?” He asked ...

It's a massive undertaking to deliver clear and consistent Olympic Games broadcasts while serving an estimated 15 million attendees hungry for smartphone connectivity in Paris. The telecommunications company Orange — the sole internet provider for the Paris Games — has nearly 1,000 staffers running its 5G-connectivity project at the Olympics. Most people in Paris use 5G to access the internet for the Olympics and beyond. But a small number of key staffers are using a 4G-powered walkie talkie style technology called push-to-talk. Ensuring PTT communications are clear for all parties using the system is a top priority for Orange, according to Bertrand Rojat, Orange's chief marketing and innovation officer. Rojat told Business Insider that 13,000 5W two way radios were being used by emergency-services personnel and organizers throughout the Games. He said these devices use a "special mechanism" to give them priority over attendees who are using devices on the default public 4G network. Walkie-talkie-style systems like PTT are often used in a public-safety capacity, such as with firefighting and emergency services, where relaying information quickly and clearly is essential. Rojat said the Paris Games are the first Olympics where the PTT service is running on an operator's current mobile network. But PTT technology has long been essential for the event. The International Olympic Committee has used these devices to oversee athlete teams competing in events and communicate with volunteers, health and safety workers, and Olympic security teams in a simple and secure manner. At previous Games, PTT services ran over a Terrestrial Trunked Radio network. TETRA is a standardized way of hosting two-way radio communications across a narrowband network.

Across a grassy field at South Seattle College, people in orange and yellow neon safety vests set up 60-foot antennas, linked together by wires strung up like a clothesline. Solar panels powering radios and receivers stretched across the field and parking lot. It was Seattle Radio Field Day, a 24-hour event where radio hobbyists connected with others on air across the world, learned about rugged 2 way radios and practiced radio emergency preparedness. For many, the thought of a natural disaster occurring in their city is an unsettling one. Some people, however, know exactly what they would do. For instance, locals involved with the Seattle Emergency Hubs organization, a volunteer-based group that teaches Seattleites about emergency situation preparedness, would report to their nearest hub, a designated meeting place for community members in the event of a natural disaster. Others, like those in Seattle-area amateur radio clubs and the Seattle Auxiliary Communications Service, would get on air to connect with other parts of the city and the Seattle Office of Emergency Management to relay information. The Seattle Emergency Hubs were first formed in 2007 after a major windstorm knocked down power lines. Ann Forrest, the organization’s North Seattle Hubs coordinator, said the event led to neighbors meeting on street corners to share information and resources. At South Seattle College in late June, RVs and campers filled a parking lot, where members of local radio groups had set up camp for outdoor two way radio training exercise. Volunteers and members from Cascadia Radio, Puget Sound Repeater Group, West Seattle Amateur Radio Club and Seattle Auxiliary Communications Service spread across sidewalks and the field. Some used Morse code to send messages, while others used computers to watch radio frequencies coming from across the world. “Amateur radio operators are people who are prepared with systems that will function even if all the communication systems go down,” said Susanna Cunningham, Lake City Emergency Communication Hub captain and the communications service’s public information officer. “Should there be a major event, their job is to help the community help each other.” The communications service, which is volunteer-based and includes about 150 licensed amateur radio operators and registered state emergency workers, collaborates with the Office of Emergency Management to ensure there’s a communication link between the city and its communities. Many of the radio community members brought their own equipment，including high power radios and portable mini walkie talkie to the Radio Field Day. Bill Thomassen, a member of the West Seattle Amateur Radio Club, set up his computer and a radio to teach members of the community about a system called Winlink, a program that doesn’t require the internet but can relay and receive messages by radio. Using this system, Thomassen connects his computer to a radio, which can transmit via email any messages to ...

Amateur radio operators — "Hams" in the vernacular — are often called upon to use their equipment-both radio and handheld two way radios during difficult times. Showing those skills recently were members of the Fort Myers Amateur Radio Club Inc. who participated in a national amateur radio Field Day exercise. John Scharbrough, a member of the Fort Myers Amateur Radio Club and co-chair for the Field Day here, said the event is an annual event sponsored by the American Radio Relay League — ARRL —, which promotes getting out and operating portable planning for emergency preparedness and practicing. "It's a very social event. Obviously, it's an event to get out in front of the public a little bit with ham radio-including analog walkietalkie and amateur radio dmr since we're setting up in a public place," he said. The emergency aspects of it are important as well. "It's an awesome hobby, but it's also a way of being prepared for emergencies," he said. "It's a lot of fun as a hobby. If you're concerned about emergency communications, and want to know best emergency radio，the way to do it is get into it with a hobby. " Jon Wells, assistant emergency coordinator for the Amateur Radio Emergency Services Group — called ARES — explained what field day does: "It allows us to test ourselves in a portable operation. When we're portable, that means maybe we're helping emergency management or we are helping a service agency like the fire department, police department or something like that because they've had a communications failure." Leo Windler, of Cape Coral, got involved after he moved here from Indiana. He, too, said the emergency aspect is an important one for him. "When there's a hurricane, or loss of communication someplace, we can come in and step in," he said. "So that's why I kind of do this." Windler said there's a ham operator on Sanibel that called in helicopters up to Sanibel for emergencies during Hurricane Ian. After Ian hit, Windler said he didn't have any cell servers for a week. "But with this, I can still send emails and text messages. We'd actually talk to people," he said. Since 1933, ham radio operators across North America have established temporary ham radio stations in public locations during Field Day events to showcase the science and skill of amateur radio. Field Days help to showcase how amateur radio works reliably under any conditions from almost any location to create an independent communications network. These types of operations are especially important for post-hurricane communication. “Ham radio functions completely independent of the Internet or cell phone infrastructure can interface with laptops or smartphones, and can be set up almost anywhere in minutes. That’s the beauty of amateur radio during a communications outage,” Bob Inderbitzen, national spokesperson for ARRL. “In today’s electronic do-it-yourself environment, ham radio remains one of the best ways for people to learn about electronics, physics, meteorology, ...
