09/13/2017 After a 6-hour flight, astronauts Mark Vande Hei, KG5GNP, and Joe Acaba, KE5DAR, and cosmonaut Alexander Misurkin arrived at the International Space Station on September 12. The trio launched aboard the Soyuz MS-06 spacecraft from Kazakhstan, orbited Earth four times, and then docked at the space station. The hatches between the spacecraft and station opened early on September 13. The arrival of Vande Hei, Acaba, and Misurkin restores the station’s crew to six. They join Expedition 53 Commander Randy Bresnik, and Flight Engineers Sergey Ryazanskiy and Paolo Nespoli, IZ0JPA, on station. The new Expedition 53/54 crew members will spend […]

QST Announces 2017 Antenna Design Competition Winners

09/12/2017 A state of emergency continues in Southern Mexico as new aftershocks occurred today in the wake of a magnitude 8.1 earthquake last Thursday. The aftershocks were in the coastal zone of the Isthmus of Tehuantepec. Preliminary reports indicate a magnitude 5.0 temblor today 35 kilometers to the south of Salina Cruz, Oaxaca; a 4.7 magnitude aftershock today 125 kilometers southwest of Tonala, Chiapas, and a 4.6 temblor today 115 kilometers southwest of Pijijiapan, Chiapas. There does not appear to be any danger of significant damage from these aftershocks. The National Emergency Net (RNE) could activate on 7.060 and 14.120 […]

State of Emergency Continues in Southern Mexico, Emergency Net Could Activate

09/12/2017 Radio Miami International (WRMI) reported on its Facebook page that Hurricane Irma did extensive damage to the station’s studio/transmitter site in Okeechobee, Florida. The station is off the air entirely. “Two antenna towers are down and many poles holding transmission lines are also down. Power went out at around 2030 UTC Sunday, and it may not be restored for days. Meanwhile, all transmitters are off the air,” WRMI reported on its Facebook page, where the station has been posting updates. “We are off the air since Sunday night,” WRMI Manager Jeff White told ARRL. With Internet service also out, […]

Hurricane Irma Extensively Damages International Broadcast Station in Florida

09/08/2017 At this time, it is ARRL’s understanding that only Amateur Radio Emergency or Amateur Radio Priority traffic is moving in and out of areas affected by Hurricane Irma. Amateur Radio Health and Welfare communications are being queued up for later delivery into the affected area, as the emergency and priority traffic eases.  In the aftermath of a natural disaster, it is human nature for persons outside of the affected area to seek information on their loved ones. Those wishing to send Health and Welfare queries are encouraged to use the American Red Cross’s “Safe and Well” website to facilitate […]

No Amateur Radio Health & Welfare Traffic At this Time;

09/08/2017 ARRL has set up a temporary phone number that ARRL section leadership can use to communicate Hurricane Irma-related information or requests to ARRL Headquarters. The number will be monitored at W1AW when the station is staffed. During off-hours, the number will be forwarded to an on-call ARRL staffer. This number should also be used to report problems such as extended interference with ongoing emergency communications. The number is 860-594-0337. Source link

ARRL Establishes Hurricane Irma Hotline for ARRL Section Leadership

09/06/2017 The ARRL September VHF Contest gets under way on September 9 at 1800 UTC and wraps up on September 11 at 0259 UTC. This popular operating event provides a chance for radio amateurs at all levels to experience contesting on the most popular VHF and UHF bands, as well as on those less-frequented frequencies above 450 MHz. Newcomers and veterans alike will attempt to work as many 2 × 1 grid squares as possible on frequencies above 50 MHz from home stations, from the field, or from “rovers” that travel from grid square to grid square. With a heightened […]

The ARRL September VHF Contest Requests your Presence!

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

09/06/2017 A new “pre-release” version of WSJT-X now is available. This is the Amateur Radio digital software suite developed by Joe Taylor, K1JT, that includes the new FT8 mode, which has been catching on like wildfire. The September 2 release, WSJT-X version 1.8.0-rc2, fixes a number of issues, provides better performance, and offers some new features. “Implementation of FT8 and its auto-sequencing feature is now more capable and more polished,” Taylor said in the release notes. “The decoder is faster and better. It now includes signal subtraction, multi-pass decoding, and the use of accumulated ‘a priori’ information as a QSO […]

New “Pre-Release” Version of WSJT-X Includes FT8 Changes

09/06/2017 NOAA’s Space Weather Prediction Center (SWPC) has upgraded its geomagnetic storm watch for today and tomorrow (September 6 and 7) to G3 (Strong). “The G3 Watch is in anticipation of the expected arrival of a coronal mass ejection (CME) that took place in association with an M5 flare,” the SWPC said. The Center said its current analysis and forecasts indicate that the CME will arrive late on September 6, with CME effects continuing into the next day. The primary area of impact is “large portions of the sunlit side of Earth,” and blackouts for up to an hour. Auroral […]
