The low pressure system which thwarted attempts by the 3Y0I team to arrive at Bouvet was such a powerful storm that it has its own definition: BOMBOGENESIS. According to reports on Bouvetoya.org – “the captain analyzed the latest weather reports indicating a chance to break through the storm – as it hadn’t been that strong […]

Can our brains sense Geomagnetic Storms? Do we have an “internal radar” that tells us when the sun is active?
Brain waves respond to Magnetic Fields (Credit: Earth to Sky Calculus)
I ran across this article this morning posted at http://SpaceWeather.com
CAN HUMANS SENSE MAGNETIC STORMS? Close your eyes and relax. Daydream about something pleasant. In this state your brain is filled with “alpha waves,” a type of electrical brainwave associated with wakeful relaxation.
Now try it during a geomagnetic storm. It may not be so easy. A new study just published in the journal eNeuro by researchers at Caltech offers convincing evidence that changes in Earth’s magnetic field can suppress alpha waves in the human brain.

Southgate ARC - New research published by neuroscientists at Caltech shows that sudden changes in Earth’s magnetic field affect human brainwaves–specifically, depressing alpha waves associated with wakeful relaxation. This raises the possibility that humans can sense geomagnetic storms

The Spring 2019 SPRAT showed up in the post yesterday and I’ve only had a chance to quickly peruse it. My ritual is to scan it about a dozen times quickly, making mental note of things of special interest to me, before devouring the entire thing before the next edition crosses the transom.
On first pass my eye was caught by A Balloon Supported Aerial written by Chris, G3XIZ. He describes a sort of stealthy arrangement where an inexpensive balloon is filled with generated hydrogen gas and used to “float” a wire vertically to heights not easily achieved with physical towers and masts.
In low wind (less than 5mph) conditions the balloon is released, and a hand crank feeds out lightweight antenna wire as the balloon ascends. After an operating session, the balloon and antenna wire are cranked back to Earth.
Part of my interest is that I proposed a similar idea a couple of decades ago. In my scheme, the balloon and winching mechanism would be installed in a fake dog house at the back of the yard. In low-wind conditions (and after dark), I imagined pulling back the roof on the dog house and releasing the filled balloon after a similar fashion.
The entire concept was based on a story told by my friend Don Pasley, K4KXL (SK) who was present at a Field Day operation that used a balloon to support a 160 meter vertical that worked marvelously until thunderstorms moved in quickly from the west and suddenly he could see arcs and sparks between the capacitor plates on the tuner and they quickly cut loose the balloon and ran for cover.
Now that’s real radio adventure!

Many thanks to SWLing Post contributor, Kim Andrew Elliott, who shares the following article and writes:

THE USAGM AUDIENCE INCREASE: LESS STARTLING THAN MEETS THE EYE
by Kim Andrew Elliott
A February 2019 email newsletter from John Lansing, CEO of the U.S. Agency for Global Media (new name for the Broadcasting Board of Governors) proclaimed that “2018 was a banner year” for USAGM. He noted that “USAGM programming was consumed by 345 million adults weekly worldwide—including radio, television and internet—an unprecedented year-on-year increase of 67 million from 2017.” This refers to the USAGM’s Audience Impact Overview for 2018 issued November 2018.
That would be a 24 percent increase in one year. As an international broadcasting audience research analyst for 42 years (10 in academia and 32 for the Voice of America and its parent agencies), a 24 percent “year-on-year” increase gets my notice. Why there was such a dramatic increase? Did a major war break out, causing people to seek information from abroad? No, nothing beyond the ongoing simmering regional conflicts. Did one of the USAGM entities score a new television affiliate, with a prime-time slot in a populous country? If that had caused the increase, I am sure it would have been highlighted in the report.
According to the press release (apparently no longer at the USAGM website but available here), “The measured weekly audience grew to 345 million people in FY 2018, from 278 million people in FY 2017, an unprecedented increase of 67 million.” The reader could easily interpret this as a sudden one-year audience increase of 67 million, but it is actually a change in the “measured” audience.[…]

 Amateur Radio Emergency Service® (ARES®) volunteers in Colorado stepped up as a mid-month “bomb cyclone” winter storm struck the state, with heavy rain shifting to heavy snowfall. The storm affected several states and led to significant flooding in Nebraska. Parts of Colorado recorded winds of nearly 100 MPH and record-low barometric pressure readings. ARES teams in Colorado began preparations a day ahead of the weather event.
Pikes Peak ARES alerted its personnel via email and a regularly scheduled Tuesday net and coordinated with the Special Communications Unit (SCU), a special cadre of radio amateurs in the Pikes Peak Regional Office of Emergency Management (OEM). Most SCU members also belong to ARES, but when called up by the OEM, they wear their SCU hats. The SCU planned to deploy to the Emergency Coordination Center (ECC) on March 12 and be ready to operate first thing in the morning.
At the time, the Red Cross did not anticipate needing Pikes Peak ARES support, so the ARES district planned to undertake weather spotting for the National Weather Service (NWS) office in Pueblo and relaying status information to the ECC. By the morning of March 13, however, the storm’s timing had changed, and the Red Cross requested ARES operators in four shelters, creating a problem with recruiting and deploying sufficient volunteers in time. Three ARES volunteers were identified, but by then the weather was so severe that only one was able to get through, amid difficulties.
At the request of NWS Pueblo, a formal weather net was called up and ran for more than 10 hours, even though the primary and back-up net control stations lost power for several hours. Some 70 operators provided reports during the storm and its aftermath. An informal net continued for another 16 hours until the SCU operators were released from the ECC.
 “While the net started out as a weather net, it quickly became a common way for operators to report stranded motorists, requests for assistance, abandoned vehicles, Good Samaritan rescues — important so that the ECC could clear police, fire, rescue, and National Guard units from responding — shelter status, and requests about road conditions,” said John Bloodgood, KD0SFY, Pikes Peak ARES Emergency Coordinator and Public Information Officer (PIO). The storm stranded more than 1,000 motorists in El Paso County.
Neighboring Douglas and Elbert counties also took proactive measures on March 12, opening emergency operations centers (EOCs) in anticipation of the storm. Both counties count on ARES of Douglas and Elbert Counties (ARESDEC) radio to support communication in emergencies. Before the heavy rain turned to snow, the two counties had already begun to open shelters. The ARES team’s operations staff closely followed weather forecasts and knew this activation would be different.
“Our preferred procedure is to keep our operational periods to about 8 hours,” ARESDEC Operations Chief Denny Phillips, W0DDP, explained. “However, we knew that once our people were in place, especially on the eastern plains, that providing relief would not be possible. Our people would have ride out the storm in the shelters.”
As the storm progressed, it became clear to county officials that additional shelters would be needed. ARESDEC operators assisted the Red Cross in setting up shelters and organizing and managing food service.
“These were incredibly difficult circumstances for the people in the shelters,” said ARESDEC operator Dick Bush, WB0EVA. “I had a very good experience and would do this again in a minute.”
By the end of the storm, more than 1,100 people were hosted in eight shelters across the two counties. ARESDEC deployed 17 radio operators. Emergency Coordinator Jim Rooney, N4JJR, praised the volunteers’ performance, saying, “Our team performed well above expectations due to their commitment to training and willingness to serve.”
Colorado Section Emergency Coordinator Robert Wareham, N0ESQ, oversaw and took part in the overall response. — Thanks to Pikes Peak ARES EC and PIO John Bloodgood, KD0SFY, and ARESDEC PIO Ron Coffee, KD0TRY

 Starting on April 1, Amateur Radio on the International Space Station ( ARISS) will accept applications from US schools, museums, science centers, and community youth organizations (working individually or together) interested in hosting contacts with orbiting crew members on the International Space Station (ISS). Contacts will be scheduled between January 1 and June 30, 2020.
Each year, ARISS provides tens of thousands of students with opportunities to learn about space technologies and communications through Amateur Radio. The program provides learning opportunities by connecting students to astronauts aboard the ISS through a partnership between ARRL, AMSAT, and NASA, as well as other Amateur Radio organizations and worldwide space agencies. The program’s goal is to inspire students to pursue interests and careers in science, technology, engineering, and mathematics (STEM) and Amateur Radio.
“Educators overwhelmingly report that student participation in the ARISS program stimulates interest in STEM subjects and in STEM careers,” ARISS said in announcing the contact opportunities. “One educator wrote, ‘Many of the middle school students who took part in and attended the ARISS contact have selected science courses in high school as a result of that contact.’” ARISS says enthusiasm sparked by a school contact has led to an interest in ham radio among students and to the creation of ham radio clubs in schools. Some educators have even become radio amateurs after experiencing a contact with an ISS crew member.
ARISS is looking for organizations capable of attracting large numbers of participants and integrating the contact into a well-developed, exciting education plan. Students can learn about satellite communications, wireless technology, science research conducted on the ISS, radio science, and any related STEM subject. Students learn to use Amateur Radio to talk directly to an astronaut and ask their STEM-related questions. ARISS will help educational organizations locate Amateur Radio groups who can assist with equipment for this once-in-a-lifetime opportunity for students.
The deadline to submit proposals is May 15. Proposal webinars for guidance and questions will be offered on April 11 at 7 PM EDT (2300 UTC) and on April 16 at 9 PM EDT (0100 UTC on Wednesday, April 17). Advance registration is required. More details, such as expectations, proposal guidelines, and the proposal form, are on the ARISS website.

 Video introduction from Icom Inc. to the IC-SAT100 which is Icom’s first Satellite PTT handheld radio that uses the Iridium satellite communication network. Unlike satellite phones, the IC-SAT100 will provide radio service to users with a push of the transmit (PTT) button. It can be used as a communication tool in remote, isolated areas where there are no mobile phones or landline network infrastructure, such as mountainous areas, remote islands and desert areas. Even if terrestrial network infrastructure is rendered unusable by human or natural disasters, satellite communication can provide a stable backup.

Former Analyst Challenges USAGM Audience Measurement Methods, Claims of Sharp Increases
By Dan Robinson
A former analyst for the U.S. Agency for Global Media, which oversees taxpayer-funded broadcast and online media directed at overseas audiences, has publicly challenged the methods used by the agency in making audience size claims.
An audience research analyst for the U.S. Agency for Global Media (formerly the Broadcasting Board of Governors) for many years, Kim Elliott, Ph.D., is the first former official to raise questions about USAGM figures.
His views, published online by the University of Southern California Center for Public Diplomacy blog, also appeared first in a small circulation subscription journal published by NASWA (North American Shortwave Association). This article is based on both pieces.[…]
Dan also points out the following BBG Watch article which focuses on Twitter polls:
