/////////////////////////////////////////// US Air Force Wants to Plasma Bomb the Sky Using Tiny Satellites: Posted: 11 Aug 2016 08:36 AM PDT http://www.eham.net/articles/37357 Can you hear me now? The US Air Force is working on plans to improve radio communication over long distances by detonating plasma bombs in the upper atmosphere using a fleet of micro satellites. Since the early days of radio, we've known that reception is sometimes better at night. Radio stations that cannot be picked up by day may be heard clearly at night, transmitting from hundreds of kilometres away. This is down to changes in the ionosphere, a layer of charged particles in the atmosphere that starts around 60 kilometres up. The curvature of Earth stops most ground-based radio signals travelling more than 70 kilometres without a boost. But by bouncing between the ionosphere and the ground they can zigzag for much greater distances. At night the density of the ionosphere's charged particles is higher, making it more reflective. This is not the first time we've tinkered with the ionosphere to try to improve radio communication and enhance the range of over-the-horizon radar. HAARP, the High Frequency Active Auroral Research Program in Alaska, stimulates the ionosphere with radiation from an array of ground-based antennas to produce radio-reflecting plasma. /////////////////////////////////////////// DX News -- ARRL DX Bulletin #33: Posted: 11 Aug 2016 08:33 AM PDT http://www.eham.net/articles/37356 This week's bulletin was made possible with information provided by QRZ DX, the OPDX Bulletin, 425 DX News, The Daily DX, DXNL, Contest Corral from QST and the ARRL Contest Calendar and WA7BNM web sites. Thanks to all. /////////////////////////////////////////// FCC 'Symbol Rate' Rule Making Proposal Open for Comment at Least Until Oct: Posted: 11 Aug 2016 08:33 AM PDT http://www.eham.net/articles/37355 In a July Notice of Proposed Rule Making (NPRM) in WT Docket 16-239, the FCC proposed to revise the Amateur Service Part 97 rules in response to the ARRL's so-called "Symbol Rate" Petition for Rule Making (RM-11708), filed in late 2013. The proceeding will remain open for public comment at least for another 60 days, since the NPRM has not yet appeared in The Federal Register, thus starting the 60-day clock. /////////////////////////////////////////// Just Ahead In Radiosport: Posted: 11 Aug 2016 08:33 AM PDT http://www.eham.net/articles/37354 Just Ahead In Radiosport: /////////////////////////////////////////// New Hamvention Venue: 'You Will Be Very Impressed,' Chairman Assures: Posted: 11 Aug 2016 08:33 AM PDT http://www.eham.net/articles/37353 Dayton Hamvention is moving on after 52 years at Hara Arena, and 2017 preparations at the show's new venue in Xenia, Ohio, now are in full swing, two Hamvention officials explained this week on the Amateur Radio Roundtable webcast hosted by Tom Medlin, W5KUB. /////////////////////////////////////////// Growth In New Amateur Radio Licensees Ahead of Last Year's: Posted: 11 Aug 2016 08:32 AM PDT http://www.eham.net/articles/37352 The ARRL Volunteer Examiner Coordinator (VEC) reports that 20,447 new US Amateur Radio licenses have been issued since January 1. That's nearly 1500 ahead of the number that had been issued by this time last year. At the present pace, the US is on track to exceed 30,000 new radio amateurs for the third straight year by the end of the year. /////////////////////////////////////////// Amateur Radio Sleuthing Pins Down Source of Strange RF Interference: Posted: 11 Aug 2016 08:32 AM PDT http://www.eham.net/articles/37351 Police in Evanston, Illinois, contacted the ARRL Lab, after an apparent interference source began plaguing wireless vehicle key fobs, cell phones, and other wireless electronics. Key fob owners found they could not open or start their vehicles remotely until their vehicles were towed at least a block away, nor were they able to call for help on their cell phones when problems occurred. The police turned to ARRL for help after striking out with the FCC, which told them it considered key fob malfunctions a problem for automakers, although the interference was affecting not just key fobs but cell phones -- a licensed radio service. ARRL Lab EMC Specialist Mike Gruber, W1MG, feels the FCC should have paid more attention. /////////////////////////////////////////// The Doctor Will See You Now! Posted: 11 Aug 2016 08:29 AM PDT http://www.eham.net/articles/37350 "SWR" is the topic of the current episode of the "ARRL The Doctor is In" podcast.

The sprawling facility now is under the ownership of the University of Alaska Fairbanks (UAF), and the UAF Geophysical Institute is preparing HAARP for a new sponsored research campaign that's set to begin early next year, UAF Researcher Chris Fallen, KL3WX, told ARRL. /////////////////////////////////////////// Amateur Radio Plays Critical Role In Mountain Rescue: Posted: 11 Aug 2016 08:27 AM PDT http://www.eham.net/articles/37346 Glenn Fowler, N5TDJ, of Allen, Texas, reported via Facebook that Amateur Radio served him well on August 4. "We were on a treacherous Jeep trip up at about 13,000 feet with several other Jeeps in Colorado," he said in his post. "One person there from Texas had a heart attack. There was no cell phone service. I tried a few repeaters and the National Simplex Frequency and was amazed that no one was monitoring any of them. I kept trying and finally reached an ARES station on a Breckenridge linked repeater that took our GPS coordinates and dispatched an ambulance to meet us at the first place they could intercept the trail." /////////////////////////////////////////// ARES Day In Palm Beach County Recruits 15 New Members: Posted: 11 Aug 2016 08:29 AM PDT http://www.eham.net/articles/37345 It was ARES Day on July 30 in Palm Beach County, Florida.

The Red Cross provided lunch. /////////////////////////////////////////// New SO-50 Distance Record Set In Youth DX Adventure Contact: Posted: 11 Aug 2016 08:27 AM PDT http://www.eham.net/articles/37344 When Patrick Stoddard, WD9EWK, in Phoenix, Arizona, worked Faith Hannah Lea, AE4FH -- on Saba and operating as PJ6Y -- the contact broke the distance record on the SO-50 (SaudiSat) satellite. /////////////////////////////////////////// ARISS US Team to Host ARISS-International Summit: Posted: 11 Aug 2016 08:28 AM PDT http://www.eham.net/articles/37343 The US Amateur Radio on the International Space Station (ARISS) team will host the ARISS-International "face-to-face" summit in the Houston, Texas, area this fall. A highlight of the November 15-18 gathering will be a tour of NASA Johnson Space Center (JSC) -- across the street from the meeting site at the ISS Conference Facility, 1800 Space Park Drive, Nassau Bay, Texas. Members of the public may attend as observers. /////////////////////////////////////////// Tuskegee Airman, Congressional Gold Medal Recipient, KB2OFY, (SK): Posted: 11 Aug 2016 08:26 AM PDT http://www.eham.net/articles/37342 Tuskegee Airman and Congressional Gold Medal recipient Julius T.
