Bharthi Prasad, a well-known ham (amateur radio) operator in India, has helped with several relief operations across the country during natural calamities. Testing times had come once again for her when she saved the lives of terrified Indian students in Ukraine at the beginning of the war, from her radio shack in Saidabad. “I got in touch with a radio HAM from Ukraine while making contacts. He identified himself as Vishnu, a Keralite, and informed that there are several Indian students with him in a bunker, some 30 km from Kyiv,” she shares. On not receiving any response from the Indian government, she contacted radio HAMs in Poland and Budapest, who then gave their details and helped the students to be evacuated. Amateur radio refers to two-way radio sets that are used to communicate with one another and the ones who operate it are called HAMs. Shashi Bhushan, director of Lamakaan Amateur Radio Club (LARC), says, “Ham radios are similar to what the military and the police use, only the frequencies on which they communicate is different. As commercial entities can’t access it, the common man can use it for free.” The hobby of amateur radio is almost a century old and has witnessed a downfall over the course of time. Despite it all, Hyderabad has seen a steady rise in its user base, thanks to those who have etched its path towards the fame it garners today. Eighty one-year-old retired  Lead Aircraftman Sriramamurthy Suri, a decorated war veteran from Masab Tank, was friends with late Prime Minister Rajiv Gandhi (a HAM himself), who requested him (Suri) to set up an organisation promoting ham radio in the country. Sriramamurthy says, “That’s how the Andhra Pradesh Amateur Radio Society war born in 1975, with a mission to help the administration in times of calamity. It was renamed as the National Institute of Amateur Radio (NIAR) in 1983.” While he trained and inspired lakhs of HAMs, he says that a very few people actually use it and most do not value the subject and the potential it holds. The writer of All About Amateur Radio laments, “People these days know little to nothing about the significance that this technology holds, except that they can appear for HAM radio licence examination after the age of 12.” In the eye of the storm Forty-nine-year-old Ram Mohan Suri, chairman of NIAR, was in the Andamans for an expedition to operate his radio set (also called DX-pedition in HAM radio lingo) when a tsunami hit the Indian Ocean. “It was a rude awakening on December 26, 2004, when I saw the television fly across the room. I realised hours later that the Sumatra-Andaman earthquake had triggered a massive tsunami. When my team and I were safe in the high ground, we refused to get evacuated and instead, started an emergency communication station to help the administration in the relief work, saving a lot of lives,” he says. Next-gen amateurs LARC consists of homebrewers who help enthusiasts with the technical expertise and material required to bu...

According to IARU news, the China Radio Association Amateur Radio Branch (CRAC) has applied for satellite frequency coordination. The China Space Station Amateur Radio Payload (CSSARC) is proposed by the China Radio Association Amateur Radio Branch (CRAC), the Shanghai Institute of Astronautical Systems Engineering (ASES) and the Harbin Institute of Technology (HIT). The first phase of the programme payload is planned to provide the following functions using the VHF/UHF amateur radio bands. 1. V/V or U/U voice calls between astronauts and ground stations. 2. V/U or U/V FM repeaters. 3. a V/V or U/U 1k2 AFSK digital repeater. 4. a V/V or U/U SSTV or digital image. The payload will provide a service to amateur radio enthusiasts worldwide, enabling contact with astronauts or communication between enthusiasts. It will also inspire students to pursue interests in science, technology, engineering and mathematics and encourage more people to take an interest in amateur radio. It is expected to be sent to the Chinese Space Station from the Wenchang Spaceport in the third quarter of 2022. It is currently in the frequency coordination phase and the exact frequencies are being coordinated, so we will keep an eye on it.

Walkie-talkie communication app Zello has become the latest app banned by Russian officials. On Sunday, Russia's Federal Service for Supervision in the Sphere of Telecom, Information Technologies and Mass Communications, also known as Roskomnadzor,announcedthat it is banning Zello for spreading "false information" about the invasion of Ukraine. "On March 4, Roskomnadzor, based on the decision, sent the administration of the American Internet resource Zello a request to stop sending messages to users that contain false information about the course of a special operation of the Armed Forces of the Russian Federation on the territory of Ukraine," Roskomnadzor said in a translated statement. "The administration of the Zello Internet resource did not comply with the requirement of Roskomnadzor within the period established by law. Due to the failure of the administration of Zello to comply with the requirements of Roskomnadzor, access to this application on the territory of the Russian Federation will be limited within 24 hours."

“Juston has maintained stable business growth under the epidemic. In the face of the continuing supply chain crisis in 2022, we have closer contact with our supplier partners. Although the production cost and supply chain crisis affect all walkie talkie manufacturers, we will make Juston more stable in the new year through the upgrading of production process and increasing R & D investment, so as to bring better service experience to our customers.”

This is our placement machine, which is located at the front end of the SMT production line. Its function is to leak solder paste or patch adhesive onto the PCB pad to prepare for the welding of components.

Understanding the Evolution of Walkie-Talkie Technology in a Changing Market In today’s fast-paced world, efficient communication is crucial, and walkie-talkies continue to be an essential tool in a variety of industries. From construction sites to outdoor adventures, and from security operations to emergency response teams, the demand for reliable, instant communication devices remains strong. However, as technology advances, the walkie-talkie market is evolving, and so are the expectations of users. As we move forward, it's vital to understand the latest trends shaping the walkie-talkie industry. Whether you're a business looking for communication solutions or a manufacturer exploring the future of product design, staying informed about these trends can help you stay ahead of the curve. 1. Integration of Digital and Smart Features Traditional walkie-talkies are evolving into digital communication devices, incorporating smart features that enhance their functionality. Digital walkie-talkies, which use digital signal processing (DSP), offer clearer audio, better range, and superior encryption. These devices are also more energy-efficient, extending battery life and offering better noise reduction, making them ideal for outdoor and professional environments. Moreover, with the rise of IoT (Internet of Things), walkie-talkies are becoming more integrated into smart networks. Features such as GPS tracking, integration with smartphones or cloud systems, and remote monitoring are becoming increasingly common. These innovations are opening new opportunities for industries like logistics, fleet management, and security. 2. Longer Range and Improved Durability One of the key trends in the walkie-talkie market is the demand for longer communication ranges. Users, especially those in industries like construction, mining, and outdoor events, require walkie-talkies that can maintain clear communication over larger distances, even in challenging environments. As a result, manufacturers are focusing on improving the power output and antenna systems of their devices, allowing walkie-talkies to reach greater distances while maintaining quality signals. Additionally, more rugged designs are being introduced to withstand extreme weather conditions. Walkie-talkies with IP67 or IP68 waterproof ratings and shock-resistant bodies are now the norm for many professionals who work in tough environments. 3. Focus on Battery Life and Power Efficiency Long-lasting battery life is always a priority for users who depend on walkie-talkies for extended periods of time.
