California Storms: Amateur Radio is Ready

Southern California continues to feel the effects of a significant rain event that began last week, bringing record rainfall, landslides, and hurricane-strength winds. The heavy rain is the result of two atmospheric rivers, referred to as "Pineapple Expresses" because of their origins near Hawaii. Nearly half a year's worth of rain has fallen in two days. Since Sunday, February 4, areas in Los Angeles County have seen nearly one foot of rain, which has now moved east into western Arizona, southern Nevada, and southwestern Utah, raising the risk of flash flooding in those areas.

ARRL Director of Emergency Management Josh Johnston, KE5MHV, has been in contact with Amateur Radio Emergency Service® (ARES®) leadership from throughout the affected area. "ARES member-volunteers are ready to be pressed into service when called upon by one of their local served agencies," he said.

The situation continues to evolve, Johnston has received several situation updates from ARES leaders.

ARRL San Joaquin Valley (SJV) Section Emergency Coordinator Dan Sohn, WL7COO, wrote:

The SJV Section is experiencing electrical power outages caused by high winds affecting tens of thousands of homes and businesses mostly in the westernmost, lower-elevation Central Valley counties and elevations at or above about 3,500 feet above sea level... The incoming atmospheric river appears to be moving more to the north than the last two storms, so we'll see what that brings the SJV counties that are already saturated... and [we] hope that it lessens the life-threatening, ongoing damage throughout southern California.

Johnston also received this update from ARRL Nevada Section Emergency Coordinator John Abrott, KD7NHC:

Here in northern Nevada, a varying amount of snow was received. I received reports from Carson City of 10 - 11, inches, and reports of 10 - 13 inches in Carson Valley and parts of Reno. There are several feet of snow at higher elevations. I have not received any reports of ARES members being activated. Several counties were requested to be ready in the event that their services were needed. Major roads are clear, but residential streets still have snow.

ARES teams are ready when needed and will continue monitor the situations in California and affected neighboring states. Check ARRL News for the latest updates.

Amateur Radio Goes to High School in New York City

Staten Island Technical High School is the first New York City school to receive a grant from ARRL.

ARRL Education and Learning Manager Steve Goodgame, K5ATA, said ARRL is working with the school in several ways. "We are working with them to build and equip an amateur radio station, to test and license students, and to put [science, technology, engineering, and mathematics (STEM)] kits in the classroom thanks to a grant from Amateur Radio Digital Communications (ARDC)."

Goodgame visited the school several weeks ago to help administer amateur radio license tests, and with the help of the school's engineering and technology teacher, Everton Henriques, KD2ZZT, there are now 32 juniors and seniors who are newly licensed amateur radio operators. Henriques attended the ARRL Teachers Institute on Wireless Technology last year, and he intends to return to the program in 2024 for additional preparation and training.

The ARRL Teachers Institute on Wireless Technology is a donor-funded professional development program designed to help teachers elevate their STEM programs through the use of wireless technology.

World Radio Day

World Radio Day 2024 will be on February 13, and this year's theme is, "A Century Informing, Entertaining and Educating."

World Radio Day was first celebrated in 2012, following its declaration by the United Nations Educational, Scientific and Cultural Organization (UNESCO) General Conference. It was subsequently adopted as an International Day by the United Nations General Assembly. Amateur radio is included in the celebration.

The EA Digital Federation designates the day as AO#WRD: World Radio Day, and they will have nine special event stations on the air on February 9 - 18. The stations will be active on different bands and modes, including phone, CW, and digital. You can locate the stations through the DX cluster or the agenda of activity on their website.

Operating times and special QSL information can be found at FEDI-EA - AO#WRD: World Radio Day 2024 (fediea.org).

In Brief...

As part of the Amateur Radio on the International Space Station (ARISS) program, students at Lilburn Elementary School in Lilburn, Georgia, were able to contact the International Space Station (ISS) on February 7 and talk to astronaut Jasmin Moghbeli, KI5WSL. The contact took place with help from Daryl Young, K4RGK, ARISS representative and member of the North Fulton Amateur Radio League (NFARL). Students were able to ask 15 questions, ranging from "What is the grossest thing about living in space?" to "Have you read the Dog Man books?" Astronaut Moghbeli said that collecting and loading the trash into a special waste vehicle is the grossest job on the ISS. As for the Dog Man books, she has not read them -- yet -- but would be interested in trying them. She also talked about growing tomatoes in space, and how her most important job on the ISS is brushing her teeth every morning. You can view a recording of the contact on YouTube.

ARISS is a cooperative venture of international amateur radio societies and the space agencies that support the ISS. In the US, participating organizations include NASA's Space Communications and Navigation (SCaN) program, the ISS National Laboratory -- Space Station Explorers, ARRL, and AMSAT.

The SouthWest Ohio DX Association (SWODXA), in conjunction with Icom® America, Inc., has announced a DX Mentor Recognition Program to recognize and reward amateur radio operators who have helped others achieve DXCC. An application form is now available for those who wish to nominate their DX mentor. Amateurs who have received mentoring from a nominee must be under 30 years of age during the calendar year of the award; targeting this age group is meant to keep such amateurs engaged in the hobby after they achieve DXCC. The judging committee will comprise SWODXA representatives and a representative from both the Northern California DX Foundation (NCDXF) and the International DX Association (INDEXA). The awards will be presented at the DX Dinner, held annually in conjunction with Dayton Hamvention®. More information and the entry form can be found at www.swodxa.org/DX-Mentor-Program or by emailing thedxmentor@gmail.com.
