03/31/2017 Midway and Kure Islands have been placed on the list of DXCC deleted entities, effective August 26, 2016. This came about as an unintended consequence of action last summer by then-President Barack Obama that expanded the Papahānaumokuākea Marine National Monument to include the northwestern Hawaiian Islands west of Ni’ihau Island, making it the largest contiguous protected conservation area under the US flag. Midway (KH4) had qualified for DXCC status by virtue of its being governed by a separate administration. Because it is now under the administration of Papahānaumokuākea Marine National Monument, however, it becomes a deleted entity. Approximately 50 […]

Midway and Kure Islands are Now Deleted DXCC Entities


03/31/2017 A pioneer on VHF, UHF, and microwave bands, and the designer of a popular Yagi model, Don Hilliard, W0PW (ex-W0EYE), of Clayton, Oklahoma, died on March 25 following a lengthy period of ill health. An ARRL member, he was 81. “Over the decades, Don made numerous contributions to the hobby and specifically in the VHF, UHF and microwave arena of Amateur Radio,” said Bill Mc Caa, K0RZ. “He was a pioneer in developing the first amateur equipment for the 900 MHz band in 1983 in anticipation of the band becoming available for amateurs. Don was a founding member of […]

03/30/2017 A STANAG 4285 intruder has been showing up on 7101.8 kHz, according to the International Amateur Radio Union (IARU) Region 1 Monitoring System (IARUMS). “The signal was strong in South America, but rather weak in Europe,” the latest edition of the IARUMS newsletter reported. “We had the same problem in earlier times. Location probably Falkland Islands.” Its unusual designation aside, STANAG 4285’s motorboat-like signals are pretty common on HF frequencies between about 2 MHz and 23 MHz. It is the data communication “modem” that North Atlantic Treaty Organization (NATO) military agencies use for the purposes of standardization, and it […]

STANAG 4285 Signal Showing Up on 40 Meters, Other Intruders Spotted



03/29/2017 Telecommunication regulators in The Netherlands have scaled back considerably the liberal 60-meter privileges announced for radio amateurs in that country just days after the conclusion of World Radiocommunication Conference 2015 (WRC-15). Since December 2015, amateurs in The Netherlands have had access to a 100-kHz wide amateur band at 5 MHz, with a maximum power of 100 W. Article 4.4 of the ITU Radio Regulations permits countries to authorize frequency assignments that are contrary to the international Table of Allocations, only on a non-interference, non-protected basis. VERON, the IARU member society in The Netherlands, now reports that starting on April […]

03/28/2017 International Space Station (ISS) Expedition 50 Commander Shane Kimbrough, KE5HOD, will take one more spacewalk on March 30 before he heads back to Earth in a Soyuz MS-02 vehicle on April 10, joined by crewmates Sergey Ryzhikov and Andrey Borisenko. The spacewalks are aimed at preparing the station for the future arrival of US commercial crew spacecraft and upgrading station hardware. On March 26, Kimbrough and Flight Engineer Thomas Pesquet, KG5FYG, of the European Space Agency, wrapped up a 6.5-hour spacewalk, during which, among other things, they successfully disconnected cables and electrical connections on the Pressurized Mating Adapter-3 in […]

03/28/2017 AMSAT has announced that the launches of its Fox-1Cliff and Fox-1D CubeSats have been rebooked from a single launch to separate launches. Both satellites initially were set to go into space on the Spaceflight Formosat-5/Sherpa mission aboard a SpaceX Falcon 9 (Sherpa is launched as a rideshare program for small, low-budget satellites). Fox-1Cliff will launch on Spaceflight’s SSO-A dedicated rideshare mission aboard a SpaceX Falcon 9 scheduled to launch from California’s Vandenberg Air Force Base in late 2017 or early 2018. Fox-1D will ride into orbit on an Indian Polar Satellite Launch Vehicle set to launch late this year. […]

03/27/2017 NOAA’s Space Weather Prediction Center (SWPC) reports a moderate (G2) level geomagnetic storm is in progress. The G2 threshold was reached on March 27 at 1948 UTC. SWPC forecasters have extended the G2 Geomagnetic Storm Warning until March 28 at 0300 UTC, as coronal hole high-speed stream effects continue to influence Earth. A large, Earth-facing canyon-shaped hole in the Sun’s atmosphere is spewing a stream of solar wind toward the planet. Visible auroral displays could descend from the Arctic Circle to northern-tier US states from New York to Wisconsin to Washington.  Source link

03/24/2017 ARRL CEO Tom Gallagher, NY2RF, is now supplementing each of his QST “Second Century” editorials with a “60-Second Century” video. These videos offer a glimpse of the content in each month’s QST editorial. ARRL began producing “60-Second Century” with the March QST editorial, and each video is posted on the ARRL YouTube channel, as well as made available through ARRL social media platforms (Facebook, Twitter, and Instagram). Videos will become available on the 10th of each month, when the digital edition of QST is released to members, and they will be archived. For his inaugural “60-Second Century,” Gallagher hit the […]

03/24/2017 Nevada mayors Carolyn Goodman of Las Vegas, John Lee of North Las Vegas, and Andy Hafen of Henderson have joined the Clark County Board of Commissioners in proclaiming March 26 to April 2 as “NVCON Week,” recognizing the ARRL Nevada State Convention (NVCON), March 31-April 2. The community leaders encouraged the citizens of their respective localities to pay tribute to the area’s Amateur Radio operators. Nevada radio amateurs will convene in Las Vegas for the NVCON. The state is home to more than 7,600 radio amateurs, many of whom provide communication support during emergencies, disasters, and public events. Featured […]

03/23/2017 A thorough and fully annotated discussion of Near Vertical Incidence Skywave (NVIS) is available in the research paper, “Radio Communication via Near Vertical Incidence Skywave Propagation: An Overview,” by Ben A. Witvliet, PE5B/5R8DS, and Rosa Ma Alsina-Pagès. First investigated in the 1920s, NVIS propagation was rediscovered during World War II as “an essential means to establish communications in large war zones such as the D-Day invasion in Normandy,” the paper notes, adding that the US Army subsequently sponsored a lot of NVIS field research, especially between 1966 and 1973. More recently, NVIS has become a popular means to enable close-in […]
