Radio Amateur Helps Rescuers to Locate Lost Hiker

Mon, 04/19/2021 - 20:46

The keen and practiced eye of ARRL member Ben Kuo, AI6YR, helped to guide rescuers to a hiker stranded on a mountainside on April 12. Hiker Rene Compean, 45, had spent the night in a remote region of the Angeles National Forest after getting in a tough spot. After a concerned friend reported Compean missing on Monday, the Los Angeles County Sheriff’s Department dispatched search-and-rescue (SAR) teams. Although amateur radio played no direct role in the rescue, Kuo cited his enthusiasm for technology and ham radio satellites and for Summits on the Air (SOTA) for helping him to develop the skills he needed to guide searchers to the most appropriate area.

“This is actually very applicable to being a SOTA activator — map, navigation skills,” Kuo told ARRL. “Also, understanding RF propagation was key to this. The SAR teams were searching the other side of the mountain, where there is no cell signal.” Kuo knew that from having hiked there before. As Kuo described it, Compean was found between four SOTA peaks.

SAR teams were deployed in the Mount Waterman area of the San Gabriel Mountains to find the hiker. According to the LA Sheriff’s Department, a low-flying helicopter team spotted him Tuesday afternoon between Triplet Rocks and the east bump of Twin Peaks in the San Gabriel Mountains, and he was airlifted to safety with no serious injuries. Kuo pointed the rescuers to the likely search area by matching satellite images with what Compean had transmitted over Twitter.

Kuo told the Los Angeles Times that he has an odd hobby of looking at photos and determining where they had been taken. He was able to employ his skill to determine the hiker’s likely location using the tiny photo the hiker posted on Twitter that shows his legs and the valley below. As the newspaper reported on April 15, “When [Kuo] saw the photo posted by the Sheriff’s Department, he set to work pulling publicly available satellite images and matching them to the vegetation and terrain below the hiker’s legs.”

Kuo’s eye was good. He sent authorities the GPS coordinates of the most likely area, and the rescue team found Compean less than a mile from that location.

As the LA Times reported, the area where Compean was located on steep slopes and very difficult to access, requiring advanced climbing skills. The Sheriff’s Department credited Kuo with saving them hours of fruitless searching. Kuo said this was the first time he’d been involved in a rescue like this one.

Home but never alone: Celebrating World Amateur Radio Day

Fri, 04/16/2021 - 15:59

Image credit: Otava Tuomi.

Early last year, when the outbreak of coronavirus (COVID-19) first pushed much of the world into lockdown, one traditional – some might even say old-fashioned – hobby experienced a spectacular revival. Amateur radio lets people interact socially, intensively, without ever meeting in person.

In those early days and weeks of the pandemic, radio amateurs reached out to each other spontaneously via the airwaves at the local, national, and global levels.

These days, local clubs in Europe and other regions are meeting on-the-air, more frequently than they have in decades, providing familiar, friendly voices, as well as regular check-ins on those, such as the elderly, who may be confined at home.

Special event stations, mostly transmitting from people’s homes, shared the message “Stay Safe” in dozens of countries and languages, reminding us all to help limit the spread of the virus.

Over the past year, on-air activity has reached unprecedented levels.

The K7RA Solar Update

Fri, 04/16/2021 - 07:37

Tad Cook, K7RA, Seattle, reports: On April 12, new sunspot group AR2814 appeared following 5 days of no sunspots. Daily sunspot numbers on the next 4 days were 16, 16, 17, and 22, taking the average daily sunspot number for the April 8-14 reporting week from 6.4 last week to 7. The April 15 sunspot number of 22 was not included in this average. So far in 2021, 39% of the days had no sunspots.

Geomagnetic indicators were quiet, with average daily planetary A index declining slightly from 6.6 to 5.1. Likewise, middle latitude A index changed from 5.6 to 4.1.

On April 14 Spaceweather.com reported a high-speed stream of solar wind from a hole in the sun’s southern hemisphere. This could produce a minor geomagnetic storm on April 17.

At 2338 UTC on April 14 and again at 0239 UTC on April 16, the Australian Space Forecast Centre issued this Geomagnetic Disturbance Warning: Geomagnetic activity is expected to increase to active levels with a chance of an isolated minor storm period from late on April 16, due to coronal hole effects. The April 16 warning said to expect the effects to continue through Sunday, April 18.

Predicted solar flux is 74 on April 16 – 19; 72 on April 20 – 21; 70 on April 22 – 23; 75 on April 24 – May 8; 72 on May 9 – 17, and 75 on May 18 through the end of the month.

Predicted planetary A index is 18, 20, and 16 on April 16 – 18; 12, 8, 5, and 10 on April 19 – 22; 8 on April 23 – 24; 5 on April 25 – 26; 10 and 8 on April 27 – 28; 5 on April 29 – May 3; 15 on May 4; 5 on May 5 – 7; 8 on May 8; 5 on May 9 – 10; 8 on May 11 – 12; 5 on May 13; 20 on May 14; 8 on May 15 – 16, and 5 on May 17 – 18.

Here’s the geomagnetic activity forecast for April 16 – May 11 from F.K. Janda, OK1HH, who has been compiled this weekly bulletin since January 1978.

The geomagnetic field will be:

  • quiet on April 25, May 1-3, 5
  • quiet to unsettled on April 26, 28-30, May 6-11
  • quiet to active on April 19-20, 23-24
  • unsettled to active April 21-22, 27
  • active to disturbed April 16-17, (18,) May 4
  • Solar wind will intensify on April (16-17,) 18-19, (21-22, then irregularly between April 23-May 1,) May 3-5, (6-7, 10-11)

Parentheses means lower probability of activity enhancement.

Jon Jones, N0JK, reported on April 15: Stations in New England spotted CE2SV and CE3SX (FF46) on 50.313 MHz FT8 ~ 2200 UTC on April 13. Likely a sporadic-E link to transequatorial propagation (TEP). AC4TO (EM70) in Florida reported 18 DX contacts in 10 countries on April 13. Solar flux was 83.

Steve Sacco, NN4X reported: Here in Florida, we saw a late-afternoon opening into Europe on both 10 and 12 meters. Looking west on 10 on FT8, I noticed ZL3IO completing a QSO with CT1ENI, and then calling EA5RW. Note that it’s the middle of the night in EU at 2034 UTC.

Don’t miss this truly remarkable presentation on “HF Ionospheric Propagation” by Frank Donovan, W3LPL, to the Central Arizona DX Association

Universe Today has an article on Galileo sunspot drawings and an application of artificial intelligence.

Here is the April 14 report and forecast from Space Weather Woman Tamitha Skov, WX6SWW.

Sunspot numbers for April 8 – 14 were 0, 0, 0, 0, 16, 16, and 17, with a mean of 7. The 10.7 centimeter flux was 74, 77.8, 70.4, 72.9, 82.8, 72.8, and 74.4, with a mean of 75. Estimated planetary A indices were 5, 3, 5, 6, 5, 5, and 7, with a mean of 5.1. Middle latitude A index was 3, 2, 3, 5, 4, 5, and 7, with a mean of 4.1.

National Science Foundation Funds Creation of Research Lab at Alaska’s HAARP

Thu, 04/15/2021 - 06:22

A 5-year, $9.3 million National Science Foundation (NSF) grant will allow the University of Alaska Fairbanks (UAF) Geophysical Institute to establish a new research observatory at the High-frequency Active Auroral Research Program (HAARP). A former military facility, HAARP is now operated by UAF and is home to HAARP Amateur Radio Club’s KL7ERP. The new Subauroral Geophysical Observatory for Space Physics and Radio Science will be dedicated to exploring Earth’s upper atmosphere and geospace environment. The facility’s 33-acre Ionospheric Research Instrument will be the centerpiece of the observatory.

“This NSF support will provide the scientific community increased access to the instruments at the observatory and, hopefully, grow the scientific community,” said Geophysical Institute Director Robert McCoy, the project’s principal investigator.

A second NSF-funded project will add a Light Detection and Ranging (LiDAR) instrument at the site, which will allow the study of other regions of the upper atmosphere. A LiDAR sends pulses of laser light to determine the composition, temperature, and structure of regions of the upper atmosphere from 90 to 150 kilometers. UAF hopes to add additional instruments over time at the Gakona, Alaska, research site.

The research grant will allow scientists to investigate how the sun affects Earth’s ionosphere and magnetosphere to produce changes in space weather. Their work will help fill gaps in knowledge about the region, which is important because ionospheric disturbances, if severe enough, can disrupt communication systems and damage the power grid.

Research at the observatory is initially expected to include the study of various types of aurora and other occurrences in the ionosphere, which stretches from about 50 to 400 miles above Earth’s surface.

The Gakona facility is a prime location for the study of the ionosphere and magnetosphere because of its location in relation to one of Earth’s magnetic field lines that reaches deep into the magnetosphere, the magnetic field that shields the planet from much of the sun’s plasma energy.

“Amateur radio will clearly benefit with an improved understanding of ionospheric propagation and space weather physics, and providing improved HF propagation prediction modeling data,” HAARP Research Station Chief Engineer and ARRL Life Member Steve Floyd, W4YHD, told ARRL. He said, “Radio science experiments will also provide a valuable data set to encourage development of new radio technologies and modulation methods useful from VLF through HF.”

Floyd is the KL7ERP trustee, which, he says, is available “to demonstrate amateur radio to visiting scientists and students, to maintain contact with Alaska hams, and to provide visiting hams with an opportunity to operate from this unique Alaska location.”

For more than 25 years, UAF, the US Air Force, the US Navy, and the Defense Advanced Research Projects Agency (DARPA) have collaborated on ionospheric research at HAARP. As Air Force funding for research and development decreased, the Air Force transferred the research equipment to UAF under an Education Partnership Agreement (EPA). The UAF Geophysical Institute operates the facility under an agreement with the Air Force.

St. Vincent Radio Amateurs on Alert During Volcano Emergency

Tue, 04/13/2021 - 13:25

Donald de Riggs, J88CD, on the Caribbean island of St. Vincent, says that on April 13, the 42nd anniversary of the 1979 eruption of the La Soufriere volcano, island residents were awakened to another column of volcanic ash creating a thick blanket, obscuring part of the eastern sky as the volcano continues to erupt violently.

“Almost all residents in the Red Zone have been evacuated, save for a few diehards who will not move, for reasons unknown,” he said. Since the effusive eruption began last December, local hams have been in a state of readiness via 2-meter networks and regional networks via HF. A 24-hour regional HF network and vigil has been active since the violent eruptions began 4 days ago, to provide communication support should telephone service be disrupted by the volcanic hazard. This includes a twice-daily link-up on HF with the Caribbean Disaster Emergency Management Agency (CDEMA).

There is also a 2-meter gateway via EchoLink on the J88AZ node. The other active VHF repeater is the main resource for domestic communications. The Grenada repeater, which is linked to St. Lucia and Barbados, is also accessible by hams in Tobago, Trinidad, and St. Vincent and the Grenadines. 

The La Soufrière volcano on St. Vincent began a series of explosive eruptions on April 9, sending clouds of hot ash some 20,000 feet into the air, blanketing much of the island in ash and causing water and power outages. The volcano is “a constant threat,” according to CDEMA. — Thanks to The Daily DX

Updated Radio Frequency Exposure Rules Become Effective on May 3

Mon, 04/12/2021 - 14:44

The FCC has announced that rule changes detailed in a lengthy 2019 Report and Order governing RF exposure standards go into effect on May 3, 2021. The new rules do not change existing RF exposure (RFE) limits but do require that stations in all services, including amateur radio, be evaluated against existing limits, unless they are exempted. For stations already in place, that evaluation must be completed by May 3, 2023. After May 3 of this year, any new station, or any existing station modified in a way that’s likely to change its RFE profile — such as different antenna or placement or greater power — will need to conduct an evaluation by the date of activation or change.

“In the RF Report and Order, the Commission anticipated that few parties would have to conduct reevaluations under the new rules and that such evaluations will be relatively straightforward,” the FCC said in an April 2 Public Notice. “It nevertheless adopted a 2-year period for parties to verify and ensure compliance under the new rules.”

The Amateur Service is no longer categorically excluded from certain aspects of the rules, as amended, and licensees can no longer avoid performing an exposure assessment simply because they are transmitting below a given power level.

“For most amateurs, the major difference is the removal of the categorical exclusion for amateur radio, which means that ham station owners must determine if they either qualify for an exemption or must perform a routine environmental evaluation,” said Greg Lapin, N9GL, chair of the ARRL RF Safety Committee and a member of the FCC Technological Advisory Council (TAC).

“Ham stations previously excluded from performing environmental evaluations will have until May 3, 2023, to perform these. After May 3, 2021, any new stations or those modified in a way that affects RF exposure must comply before being put into service,” Lapin said.

The December 2019 RF Report and Order changes the methods that many radio services use to determine and achieve compliance with FCC limits on human exposure to RF electromagnetic fields. The FCC also modified the process for determining whether a particular device or deployment is exempt from a more thorough analysis by replacing a service-specific list of transmitters, facilities, and operations for which evaluation is required with new streamlined formula-based criteria. The R&O also addressed how to perform evaluations where the exemption does not apply, and how to mitigate exposure.

Amateur radio licensees will have to determine whether any existing facilities previously excluded under the old rules now qualify for an exemption under the new rules. Most will, but some may not.

“For amateurs, the major difference is the removal of the categorical exclusion,” Lapin said, “which means that every ham will be required to perform some sort of calculation, either to determine if they qualify for an exemption or must perform a full-fledged exposure assessment. For hams who previously performed exposure assessments on their stations, there is nothing more to do.”

The ARRL Laboratory staff is available to help amateurs to make these determinations and, if needed, perform the necessary calculations to ensure their stations comply. ARRL Laboratory Manager Ed Hare, W1RFI, who helped prepare ARRL’s RF Exposure and You book, explained it this way. “The FCC did not change any of the underlying rules applicable to amateur station evaluations,” he said. “The sections of the book on how to perform routine station evaluations are still valid and usable, especially the many charts of common antennas at different heights.” Hare said ARRL Lab staff also would be available to help amateurs understand the rules and evaluate their stations.”

RF Exposure and You is available for free download from ARRL. ARRL also has an RF Safety page on its website.

The ARRL RF Safety Committee is working with the FCC to update the FCC’s aids for following human exposure rules — OET Bulletin 65 and OET Bulletin 65 Supplement B for Radio Amateurs. In addition, ARRL is developing tools that all hams can use to perform exposure assessments.
