  • A Child's Awe at Lunar Landing Leads to Space Science Career:

    This boy stood on the roof of his parents' house in Wichita, Kansas, trying to get a direct view. "I was looking at the moon through binoculars, hoping to see the landing, not aware that it was completely impossible," says professor David Knudsen, head of the department of physics and astronomy at the University of Calgary. "But we wanted to get a first-hand look, my brothers and I, so that's what we did. "I was six." Everyone who watched was awed that day. But a minority were moved to action. The moment shaped their futures, and ours. These people -- thousands of them -- have gone on to make some of the greatest scientific achievements and discoveries in human history. "I started building model rockets, got interested in amateur radio, all the things that come together in what I do now. I was following what excited me.

  • Apollo 11 Landing Had Blount County Connection:

    Historians point to Apollo 11 as the moment the United States seized the edge in the Cold War, but say the "space race" really began in World War II. It was a fight for survival as the U.S. and the Soviet Union raced to beat German scientists who were tasked with creating navigable nuclear weapons that, theoretically, could blow both nations off the map. The aviation industry was barely 50 years old when a Blount County native, Dennis Sparks, earned his pilot's license at 16. Like many pilots, he had a sharp memory and an instinctive feel for engines, according to his wife, Adele Sparks. "He was a complex and intelligent man," Adele Sparks said. "He was so well versed in things that he was interested in. Civil War history, coin collecting, antique automobiles. He was a ham radio operator and anything he was involved in he could speak on eloquently. He also could hear an airplane flying overhead and tell you what it was."

  • Radio Enthusiast Invented 'Black Box' Flight Recorder:

    On Friday 19 October, 1934, the passenger plane Miss Hobart fell from the sky to the sea. Eight men, three women and a baby boy fell with her, swallowed - it's believed - by the waters of the Bass Strait that lies between Tasmania and mainland Australia. The plane's wreckage was never found. One of those on board was a 33-year-old Anglican missionary, Rev Hubert Warren, who had been travelling to his new parish in Enfield, Sydney. His wife Ellie and four children had stayed behind, intending to follow by boat. The reverend's last present to his eight-year-old son, David, had been a crystal radio set that the boy treasured deeply. By his mid-twenties, David Warren had studied his way to a science degree from the University of Sydney, a diploma in education from Melbourne University and a PhD in chemistry from Imperial College, London. It was in that spirit that Dr Warren took to his garage and assembled his 20-year-old radio parts. He'd decided the only way to overcome his critics' mockery and suspicion was to build a solid prototype. It would be the first ever "black box" flight recorder. Though the device started to be called "the black box", the first ones off the line were orange so they'd be easier to find after a crash - and they remain so today. Today, black boxes are fire-proof, ocean-proof and encased in steel. And they are compulsory on every commercial flight. It's impossible to say how many people owe their lives to data captured in the death throes of a failing plane - to the flaws exposed, and the safety innovations that followed.

  • Bihar Ham Radio Enthusiasts Help Sick Man Reach Home in Bengal:

    Kolkata: Ham radio enthusiasts from neighbouring Bihar have been instrumental in uniting an elderly person from Jalpaiguri with his family members. Bidyut Bhattacharjee (65), a former employee of Jalpaiguri municipality, fell ill during his visit to Char Dham and was admitted at a private nursing home at Kankarbagh in Patna. He had lost contact with his family members. Bhattacharjee, who is a single, had left from his Jalpaiguri residence a few days ago informing his family members that he is venturing on a trip to Char Dham. During the journey, he fell ill suffering a cerebral attack and some local people in Patna who found him lying unconscious by the roadside and admitted him to a private nursing home. One of the family members, who was familiar with the activities of West Bengal Radio Club, which is an organisation of ham radio enthusiasts in Bengal, called up its secretary Ambarish Nag Biswas. Radio enthusiasts in Bengal immediately contacted their counterpart in Patna and sought their assistance.

  • Foundations of Amateur Radio #215:

    Recently there was a discussion on social media about the legality of various types of transmissions. Before I get into the specifics, it's worth looking at some of the rules around this. I will point out that this isn't exhaustive, but it gives you an idea of what I'm talking about.

  • In a Digital Age, Still a Need for Hams:

    The way we communicate with each other has changed tremendously over the past few decades, but amateur radio operators or "hams," are still utilizing reliable, analog point-to-point technology to aid in emergency communications. "The goal is to have as much usable coverage as possible, while having the repeater station itself physically and electrically built like a tank," McIntyre says. "We want to have a repeater that receives other stations clearly and at the same time have enough transmitter power to broadcast just as far. We want it to be dependable and reliable, too. The antenna and tower infrastructure has to survive the elements and be designed to handle multiple direct lightning strikes while staying in operation." The repeater is on backup generator power and was used to relay emergency traffic during Hurricane Florence last year. The emergency command center at the courthouse would periodically call and listen for stations that needed assistance or had radio traffic to pass along when cellular service was out.

  • Solar Activity and the Next Maunder Minimum:

    The 'Maunder Minimum' is the name given to the period from 1645 to 1715 when the number of sunspots - 'storms' on the sun - became almost zero. The period is named after the solar astronomer Edward Walter Maunder (1851-1928), who was working at The Royal Observatory at Greenwich when he discovered the dearth of sunspots during this period. During one 30-year period within the Maunder Minimum there were only about 50 sunspots compared with a more typical 40,000. The new research was led by Irina Kitiashvili, a researcher with the Bay Area Environmental Research Institute at NASA's Ames Research Center, in California's Silicon Valley. It combined observations from two NASA space missions - the Solar and Heliospheric Observatory and the Solar Dynamics

  • Humans Search for Alien Interstellar Morse Code with Arrays:

    Russian physicist, Yuri Milner has decided to partner up with VERITAS to go on the hunt for alien communication code in a completely different way. Yuri Milner decided to fund Breakthrough Listen, a science based program with the initiative of discovering extraterrestrial intelligence somewhere across the cosmos. To help them do that, Breakthrough have partnered up with VERITAS, or -- Very Energetic Radiation Imaging Telescope Array System. The goal of the partnership is to basically search the surrounding stars for alien morse code through nanosecond-long optical pulses. The most conventional way of looking for alien communication is through radio waves, so the line of thinking behind is the project is to stray away from the norm and try something different in hopes of receiving some form of information. As we don't know how aliens communicate, anything is really worth a shot. Its certainly not guaranteed that Breakthrough or VERITAS will stumble across something, but hopefully they do because it will be good to know that we aren't alone out here.

  • No Consensus Reached for FCC On 'Symbol Rate' Issues:

    ARRL-initiated efforts for rival parties to reach consensus on issues raised in the so-called "Symbol Rate" proceeding have ended. In April, the FCC granted ARRL's request for a 90-day hold in the proceeding, FCC Docket WT 16-239, to provide an opportunity for ARRL to lead an effort to determine whether consensus could be reached on some or all of the issues that commenters raised in the FCC's proceeding. The FCC already has issued a Notice of Proposed Rulemaking in WT 16-239, which stemmed from ARRL's rulemaking petition RM-11708.
