The following is a QST. U.S. hams activate again for hurricanes and wildfires. A new UK ham club finds 'virtual' success -- and a digital network for blind hams explores endless possibilities. All this and more as Amateur Radio Newsline Report Number 2238 comes your way right now. ** BILLBOARD CART ** AMATEURS RESPOND TO WILDFIRES, HURRICANES PAUL/ANCHOR: As wildfires raged in the American West and hurricanes struck farther east, hams were mobilized on the Pacific Coast and in the nation's Gulf Coast region to report and respond as needed. By Wednesday, September 16th, the Voice Over Internet Protocol Weather Net had secured as did WX4NHC, the amateur station at the National Hurricane Center. According to Lloyd Colston KC5FM, scores of weather reports were submitted for Hurricane Sally in the Gulf Coast and Hurricane Paulette which hit Bermuda. By Thursday, September 17th, ARES had activated in northern Florida, anticipating Sally. Meanwhile, the Federal Emergency Management Agency declared the first two channels on the 5 MHz band available for interoperability between hams and government agencies for both the weather systems and the West Coast wildfires. Amateur radio is secondary on the 5 MHz band. The Military Auxiliary Radio System was also prepared to assist with response on the band as needed. (SWLING POST, LLOYD COLSTON) ** MILLIMETER WAVE RADAR SHOWS PROMISE PAUL/ANCHOR: Scientists in a U.S. research lab have found a way sound waves can give a mighty boost to radar. Skeeter Nash N5ASH has that report. SKEETER: As hams we all know the power of sound and the information it can carry. Now, scientists at the United States Naval Research Laboratory are harnessing the power of vibration sensing to tell them more about moving targets. According to an article on the lab's website, using a millimeter wave radar lets operators sense what a target may be doing by detecting subtle changes in vibration. Because it is a remote- sensing technique it does not require proximity. According to the article, even a low-power system can detect a one-square-meter target that is about 10 kilometers, or 6 miles, away. Christopher Rodenbeck, an electrical engineer in the lab's Radar Division said the process adds sound to image collection already being done by radar. It relies on a new algorithm that translates small vibrations into sounds that can be measured and characterized. That algorithm still has its patent pending. Michael Walder, superintendent of the lab's Radar Division, said: [quote] "Millimeter wave radar can see things that can't be seen at other frequencies and can't be seen optically." [endquote] Millimeter wave radar is extremely accurate and has a high resolution. Its electromagnetic waves are between 1 and 10 millimeters -- at radio frequencies between 30 and 300 GHz.

Jim Meachen, ZL2BHF, has the details. JIM: A family reunion that was more than 10 years in the making finally happened earlier this month in India thanks to amateur radio. According to local news reports, Govinda Munde, 60, had been in treatment at a psychiatric hospital in Pune (Poo-NAY) and had not seen his family for many years but turned up mysteriously in February on the island where the Gangasagar (Gong-a-SOGG-ARR) Festival had just concluded in West Bengal. He was found sleeping beneath a tree, according to Ambarish Nag Biswas VU2JFA, secretary of the West Bengal Radio Club. The club had been asked by authorities to have local hams assist in locating his family. The man was admitted to a general hospital for treatment but walked out two days later. He was tracked down and readmitted sometime afterward. Hams meanwhile located his family in Maharashtra State. After some delays, the man's brother arrived only to discover that a caretaker had put him on a train. Ambarish said that Samarendra Sekhar Das VU3XSS, Dibos Mandal VU3ZII and Kalipada Patra, a shortwave listener, were able to find him on September 6th and with the help of police, the family was reunited. By the 11th of September, they were back in Maharashtra. For Amateur Radio Newsline, I'm Jim Meachen, ZL2BHF.
