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 ...

Walkie-talkies may encounter minor functional problems or malfunctions during use, firmware upgrades can optimize the performance of the device and enhance its stability. Through this radio, you can solve the following problem. How to enter programming mode on the digital radio? What steps are involved in upgrading the digital radio display? What is the purpose of the programming cable in the upgrade process? Through firmware upgrades, new features can be added to the walkie-talkie, increasing its practicality and playability.

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, ...
