09/26/2017 Brian Lloyd, WB6RQN, the Texas aviator who recently circumnavigated the globe following Amelia Earhart’s path, is spearheading “Dominica Airlift — Angels to Eden” to aid residents of the storm-stricken Caribbean island nation. The Category 5 Hurricane Maria slammed into Dominica on September 18, leaving the population of about 70,000 without power or viable telecommunications, in addition to wreaking severe damage to homes and infrastructure, including the island’s port, but sparing at least one usable airstrip. Lloyd learned this week, however, that the relief situation on Dominica is improving. “Our help is needed, but new information came in last night,” […]

09/13/2017 QST has announced the winners of its 2017 Antenna Design Competition. Following a solicitation for entries earlier this year. members submitted nearly 100 antenna designs in three categories: 160 Meters and Lower Frequencies, 80 Through 10 Meters, and 6 Meters and Higher Frequencies. Winners will receive certificates and cash prizes. The winning designs are also eligible for publication in QST and other ARRL media. 160 Meters and Lower Frequencies First Prize: Theodore P. Algren, KA6W, “A Linear-Loaded Low-Angle Radiating Delta Loop for 160.” Second Prize: Joseph H. Reisert Jr, W1JR, “160 Meter Unipole Implementation.” Third Prize: Dave Ahlgren, K1BUK, […]

QST Announces 2017 Antenna Design Competition Winners


09/06/2017 Both professional and citizen scientists conducted formal and informal investigations into the effect of the August 21 solar eclipse on HF radio propagation. Nathaniel Frissell, W2NAF, of HamSCI, has said it will take some time to get a more scientific analysis of data compiled during the Solar Eclipse QSO Party. Frissell and others are investigating whether the sudden absence of sunlight during the eclipse — and especially of solar ultra-violet and x-rays — would briefly change the properties of the upper atmosphere. Professional ionospheric researcher Phil Erickson, W1PJE, of the Atmospheric Sciences Group at MIT’s Haystack Observatory, said he […]

More Professional and Citizen Research Suggests Eclipse Briefly Affected HF Propagation



08/17/2017 ARRL, the American Red Cross, and The Salvation Army Team Emergency Radio Network (SATERN) will partner on Monday, August 21, to provide a nationwide communication link for local and regional American Red Cross units should a communications failure occur during the solar eclipse. “Concern has been expressed by public safety, emergency management, and others that the large number of people — over 7.5 million nationwide — flowing into the relatively narrow path of totality may overload and disrupt the normal communication infrastructure in some local areas,” SATERN said in its August 17 newsletter. If that happens, the Red Cross […]

Amateur Radio Communication Resources to be Available during Eclipse Day


08/16/2017 Amateur Radio will be in the service of science on Monday, August 21, as a total solar eclipse causes the shadow of the moon to traverse the US from Oregon to South Carolina in a little more than 90 minutes, obscuring the sun completely for a few minutes at any given location along the way. The sudden absence of sunlight — and especially of solar ultra-violet and x-rays — is expected to change briefly the properties of the upper atmosphere. A few hundred radio amateurs already have registered as participants in the Solar Eclipse QSO Party (SEQP), a special […]

Solar Eclipse QSO Party Will Facilitate Real Science


08/07/2017 The Solar Eclipse QSO Party (SEQP) is just a couple of weeks away! The SEQP is a special operating event organized by the Ham Radio Science Citizen Investigation (HamSCI) to study ionospheric effects caused by the August 21 total solar eclipse. During the SEQP, hams are being asked to operate on the HF bands in a manner similar to a contest or QSO party. Let the HamSCI researchers know where you plan to be and what modes you plan to operate. Visit the SEQP Pre-Registration page. Systems such as the Reverse Beacon Network (RBN), PSKReporter, and WSPRNet. Participants’ logs […]

08/04/2017 At 0549 UTC on August 3 the Australian Space Forecast Centre issued this warning: “During UT days 4-5 August expect an increase in geomagnetic activity up to active to minor storm levels due to influence of the recurrent coronal hole. INCREASED GEOMAGNETIC ACTIVITY EXPECTED DUE TO CORONAL HOLE HIGH SPEED WIND STREAM FROM 04-05 AUGUST 2017. GEOMAGNETIC ACTIVITY FORECAST04 Aug:  Active05 Aug:  Active” Spaceweather.com issued this warning later on the same day: “GEOMAGNETIC STORM WATCH: NOAA forecasters say there is an 80 percent chance of polar geomagnetic storms on Aug. 4th when a solar wind stream is expected to […]

The K7RA Solar Update


08/02/2017 Fifteen-year-old Marty Sullaway KC1CWF, of Newton, Massachusetts is the recipient of the 2017 Bill Pasternak WA6ITF Memorial Amateur Radio Newsline Young Ham of the Year (YHOTY). Licensed in 2014, he worked his way up to Amateur Extra class earlier this year. A rising sophomore year at Meridian Academy in Jamaica Plain, Massachusetts, Marty is co-founder of the Eastern Massachusetts Contesting Club (KR1DX), which he created to attract more young people to Amateur Radio in suburban Boston. He has helped to teach and mentor many young people, sparking interest in HF contesting. Joe Eisenberg, K0NEB, nominated Marty for the award, […]

05/16/2017 NOAA forecasters have issued a watch for minor-to-moderate geomagnetic storms May 16-17. Forecasters say there is a 40% chance of minor (G1) geomagnetic storming on May 16, as Earth enters a stream of solar wind flowing from a hole in the Sun’s atmosphere. The storm could intensify to moderate (G2) on May 17, due to a combination of coronal hole activity on the Sun’s surface and the impending arrival of a May 13 coronal mass ejection (CME), which is expected to deliver a glancing blow to Earth’s magnetic field. The storming could make auroral displays visible at lower-than-typical latitudes. […]

Moderate Geomagnetic Storming Forecast



04/24/2017 NOAA’s Space Weather Prediction Center (SWPC) says a minor (G1) geomagnetic storm watch remains in effect for April 24-26, due to the continued influence of a large, recurrent, negative-polarity coronal hole high-speed stream (CH HSS). A coronal hole is an area of the Sun where the magnetic field folds back, and solar wind escapes. This follows on the heels of an unexpected coronal mass ejection (CME) impact on April 22. Conditions on HF are no better than fair, with conditions on the higher bands (17 through 10 meters) deemed poor. A G1 warning had been in effect until 1500 […]
