Many motorsport figures, teams, and associations around the world have contributed to relief efforts in Ukraine in the two months since Russia began its invasion of the country. For off-road racer David Caspino, he is delivering his support firsthand. On Wednesday, PCI Race Radios—an official partner of SCORE International—announced it will donate 100 two-way VHF (very high frequency) radios to the Ukrainian Army and Territorial Defense Forces, the latter of which includes a unit for foreign volunteers like his fellow Americans, with Caspino overseeing their delivery. In a Facebook post made last Tuesday, Caspino stressed a need for Individual First Aid Kits, while off-road racing shop SDHQ Motorsports chipped in stickers and apparel; Caspino quipped on Instagram that he believes “kids in Ukraine love stickers more than Baja kids.” “PCI is proud to help support David in his humanitarian efforts and has donated 100 VHF radios for him to take over there with him,” reads a statement from the company. “Follow his journey on Facebook and reach out to him if you would like to donate any supplies. Thank you David for your efforts, you are truly a hero, be safe over there.” “It’s very rewarding and very fulfilling, but it’s pretty crazy,” Caspino told The Willits News .

Kenichi Horie （JR3JJE）, an 83-year-old Japanese amateur radio enthusiast, set off from San Francisco, USA, on 26 March local time, crossing the Pacific Ocean alone in his Suntory Mermaid III. During the trip he used his amateur radio to communicate with other ham stations. Kenichi Horie, whose goal is to become the oldest solo sailor to cross the Pacific Ocean, passed through Hawaii on 17 April, a week ahead of schedule and clearly in good shape and spirits. On 31 March he sent the following message to his assistant using a satellite phone: "For the first time since I set out, I spotted a tanker on the sea this morning. The ship is heading east. Tomorrow, I am going to use the amateur radio". On April 1st, radio amateurs across Japan tried to communicate with Horie, some using very large antennas. But they were unable to reach him due to poor transmission conditions. The next day, some people made the call successfully.  Although Kenichi Horie carries a satellite phone, communicating with others via ham radio remains one of his favorite pastimes. From weekends (Saturdays) around late May and 10 am (JST) on holidays, at a nearby frequency of 21.320MHz±, a list QSO was conducted with the assistance of radio amateurs in Horie. Try using an antenna to transmit a radio signal to the east of Horie's voyage.

Greenwich Radios, America's leading wholesale buyer and seller of used two-way radios, declared April 22, 2022, as National Two-Way Radio Day. In coordination with Earth Week, Greenwich Radios chose a date that aligns the impact of two-way radios with protecting Mother Earth and its inhabitants. "We felt that recognizing the contribution of two-way radios on our nation's growth was overdue," explains Larry Sellers, PR spokesperson for Greenwich Radios. Despite two-way wireless technology being over 100 years old, it has not fundamentally changed in the past century. Radios have become integral to public safety, aviation, maritime, small businesses, and everyday people. They are part of the American fabric. As wireless technology continues to move towards 5G and smartphones, the simple two-way radio remains as popular as ever. Due to its simplicity and reliability, point-to-point two-way radio communication will remain the gold standard of reliable and independent communications for the next 100 years and beyond. As the world continues to focus on technology, it's more important than ever to honor and celebrate the advent of two-way radio technology and its impact on making our planet better. Greenwich Radios has petitioned the National Holiday Archives to include National Two-Way Radio Day in its catalog.

On April 12, the masses reported that there was a suspected "black radio" in the urban area of Shaoyang, and the advertisement of a drug sale was broadcast in a loop. After receiving the report, Shaoyang Wireless Office immediately organized personnel to conduct special monitoring. At 9:00 a.m. on April 13, the staff finally discovered the suspected "black broadcast" signal during repeated patrol monitoring, using a frequency of 90.6MHz. The content of the signal is demodulated and monitored, and the station database is compared to further confirm that it is indeed an illegal signal. The staff then used vehicle direction finding and portable positioning equipment to lock the "black broadcast" on the roof of the 33rd floor of You'a International Plaza, Shaoyang City. Law enforcement officers collected evidence on the spot and removed relevant illegal equipment.

Starting from the 23rd, ships sailing in the South China Sea can receive radio weather fax products independently produced and broadcast by China, including typhoon, precipitation and wave forecasts. On the same day, the Guangzhou Coast Radio Station of the South China Sea Navigation Support Center of the Ministry of Transport and the Guangdong Meteorological Observatory jointly launched the South China Sea maritime radio weather fax service, filling the gap in the radio weather fax service in the South China Sea and escorting the safe navigation of ships. Maritime radio meteorological fax service is one of the important channels for ships to obtain maritime meteorological information. Compared with the traditional meteorological message, it is presented in the form of images, which has the characteristics of rich information and long forecast time. It can realize early warning of meteorological disasters, and plays an important role in ensuring the safety of ship navigation. The maritime radio weather fax service launched this time can cover the South China Sea and surrounding waters. Guangzhou Coast Radio broadcasts 11 kinds of meteorological products every day, including "sea level, precipitation, wind forecast", "wave forecast", "typhoon forecast" and "South China Sea forecast". The broadcast of radio weather fax products to the South China Sea is of great significance to enhancing the international contract performance capability and ensuring the safety of ships' navigation.

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.
