ARES and Red Cross Cooperate to Assist Storm-Affected Residents in Texas
ARRL Amateur Radio Emergency Service (ARES®) and American Red Cross volunteers joined forces in Texas under the ARRL/Red Cross memorandum of understanding in responding to the situation resulting from unseasonably frigid weather. Kevin McCoy, KF5FUZ, said the Red Cross formally requested an ARES activation in Texas to address the effects of the natural disaster, which included a lack of drinking
“We made a special effort to use Winlink email over radio to get reports of infrastructure problems and unmet needs [and to] communicate information about warming centers,” McCoy said, adding that Winlink operators provided the most valuable contribution in the disaster response. Several teams deployed to support emergency operations centers (EOCs) in Bexar, Brazos, Kerr, Travis, and Williamson counties, he added.
“Our effort in the start of the activity was to focus on folks with medical needs who required power, and to get those folks to safety,” McCoy said. “Reports from operators were passed to Disaster Program
Managers and Disaster Action Teams and to Red Cross Disaster Mental Health personnel for evaluation. Government partners and citizens provided transportation and Red Cross provided hotel rooms in areas with reliable power to keep these citizens safe while following COVID-19 protocols.”
On February 20, the Red Cross made a formal stand-down request to Texas ARES sections from the Central and South Texas Red Cross Region. “Transportation, communication, and internet had restored sufficiently to allow for that change of status,” McCoy said. “We did let all Winlink operators know that we would still monitor the tactical addresses until the disaster recovery was over.”
Key issues remaining include the prolonged power outage and the freezing weather that left Texas with damaged water infrastructure. “Things are improving rapidly,” McCoy said on February 22. Read an expanded version.

“Whirlwind Boom” Emergency Communications Exercise Set
The amateur radio communications team of Florida Baptist Disaster Relief has created a multi-site radio communications exercise dubbed “Whirlwind Boom,” designed to bring together volunteers and local agencies across northern Florida and throughout the southeastern US. The 2-hour drill is set for Friday, March 19. Invitations have gone out to Amateur Radio Emergency Service (ARES®) groups, county-level emergency managers, state
The exercise scenario involves a swarm of tornadoes coupled with the terrorist bombing of the telephone system, and large numbers of displaced residents seeking shelter. Only radio remains. During the exercise, volunteers will practice transmitting formal reports about the utility, water, and safety situations in their counties (Incident Action Plan). Many participants will communicate using portable radio gear powered by battery or generator. Simulated outbound survivor messages to friends and family will also be sent. Participating groups will receive secret messages advising them of unexpected handicaps that mimic what might happen during an actual disaster — complicating their tasks.
Amateur Radio Helping to Fill Earthquake Report “Donut Holes”
An article describing how radio amateurs can help fill the information “donut hole” by providing post-earthquake “Did You Feel It” (DYFI) reports via Winlink HF radio email appeared on February 22 in the American Geophysical Union (AGU) magazine Eos. As the article points out, “Ham radio networks gear up to provide real-time, on-the-
As the article explains, DYFI uses a questionnaire to gather individuals’ experiences and observations, and USGS uses the information to evaluate the shaking intensity at that person’s location. DYFI has been in operation since 1999 in the US and 15 years around the world, during which the USGS has gathered more than 5 million individual DYFI intensity reports.
The article notes that a potential problem is that “public access to it may be compromised as a result of strong earthquake shaking,” with affected individuals experiencing power and communication outages or may be distracted by more immediate priorities.
“USGS and other global seismic network operators have witnessed felt report ‘donut holes’ in areas of strong shaking due to loss of internet communication,” the article said, “most recently during the magnitude-5.7 earthquake that hit near Salt Lake City in March 2020.” The article suggested that “alternative pathways” of communication are needed to “gather important ground-truth shaking data with minimal delay.” And
“We now expect to sample the donut hole with the help of amateur radio groups worldwide,” the article’s authors said. “These groups can mobilize a significant number of licensed radio operators after a strong earthquake, especially near large population centers, ensuring a baseline level of macroseismic intensity reporting even in heavily affected areas.”
As the article explains, USGS has partnered with Winlink, a radio email platform with more than 28,000 users worldwide, and with ARRL Amateur Radio Emergency Service (ARES®) members. Winlink adapted the USGS DYFI questionnaire to its platform, and this version is now available to all radio amateurs, the article said. Read an expanded version.

Hams Participate in Winter Yellowstone VHF Radio Rally
Wyoming and southern Montana hams belonging to the North Yellowstone Amateur Radio Club and Park County (Montana) Amateur Radio Emergency Service (ARES®) took to the wilderness in late January during heavy snow to take part in an emergency preparedness exercise. The groups have about 15 members in all; many more bison and elk roam the roads than do hams.
The critical winter duty for North Yellowstone radio amateurs is
deployment to remote locations of winter emergencies. To train for these responses, the members devised the VHF Radio Relay, a radio scavenger hunt designed to get members out to remote road locations where winter emergencies may require radio communications support. The group uses the Eagle’s Nest repeater located at 8,000 feet on Electric Peak southwest of Gardiner, Montana — the north entrance to Yellowstone National Park. The repeater covers the northern one-third of the vast park and southern half of Park County, Montana.
Participants received two pages of instructions. The first contained directions for completing their call-out assignment and listed 15 locations that required hams to deploy to the far reaches of the radio coverage area. The second page consisted of a map. Only three roads are in the area, and conditions on one dirt road are typically difficult. Each route had five locations along the way to the terminal checkpoint. The 15 widely spaced locations guaranteed that no operator could visit all of them. Locations were chosen such that hams needed to plan their route strategy — ideally before leaving the starting point, where odometer readings were recorded.
Each location was assigned a tactical call sign, and communicators had to use GPS to verify that they were in their precise positions. At all locations, hams radioed net control to have their location verified before moving to the next location.
At the last check-in point, participating hams had to call in and were given instructions on how to find a code word hidden in an interpretive sign to verify their location — for example, the seventh word in the third paragraph — and relay it to net control. Each participant had a different code word.
Directions included a safety warning about bison and elk on the road, and bad driving conditions due to snow. All departed at 9 AM and were to be back at the starting point at 11:30 AM. A prize was awarded to the ham who visited the most locations with the lowest mileage. First place went to Doug MacCartney, K7GRZ, and second place to Reve Carberry, KX4LZ. Jim Halfpenny, K9YNP, served as net control. — Thanks to Park County Emergency Coordinator and ARRL PIO Jim Halfpenny, K9YNP
ARRL Interview Explains Background of Ham Radio in Space Film Short
Josh Tanner, the Australian filmmaker who produced the thriller Decommissioned by Perception Pictures, has explained how he came up with the idea to develop the movie short. In the approximately 6-minute film, SuitSat returns in the future to haunt International Space Station commander “Diaz,” played by Joey Vieira, who spots SuitSat, the surplus Russian Orlan spacesuit that Amateur Radio on the
An exclusive ARRL video interview premiering on Saturday, February 27, brings together Tanner, who directed the sci-fi horror film about an eerie ham-radio-in-space reencounter, and ARISS-International Chair Frank Bauer, KA3HDO. In the interview, conducted by ARRL volunteer Josh Nass, KI6NAZ, of the popular YouTube channel Ham Radio Crash Course, Tanner described the uniquely creative and technical aspects of the filmmaking involved in Decommissioned and its connection with the real-life SuitSat-1.
“My wife, Jade, who is also a co-writer of this short film, and I are both really obsessed with space, and we discovered SuitSat on
SuitSat-1 transmitted a voice message, “This is SuitSat-1 RS0RS!”, in several languages, plus telemetry and a slow-scan TV image on an 8-minute cycle as it orbited Earth.
Tanner said a lot of the films he produces involve “pieces of history that are rather quite odd or interesting that maybe a lot of people don’t know about.”
Bauer described the background of the 2006 SuitSat project, which involved ARISS’s relationship with Sergey Samburov, RV3DR.
“We had 3 weeks to pull it all together and get it ready for launch,” Bauer said, and that included getting safety approvals. SuitSat-1 operated for about 2 weeks, and a contest of sorts evolved to guess when it would burn up in the atmosphere, which wasn’t until about 6 months later. A SuitSat-2 was launched from the ISS several years later.
Tanner said the Decommissioned script was written about 3 years ago, but creating the realistic atmosphere and sets involved a number of complexities, which was “very expensive,” he revealed. A big push toward using video game engine technology in feature-film development made it possible. Decommissioned was produced using a game engine called Unreal Engine, which was also used to produce the TV show The Mandalorian.
ARRL reminds interested schools and educational organizations in the US that the latest window to submit proposals to host scheduled ham radio contacts with an ISS crew member opened on February 15. Contacts would be scheduled January 1 – June 30, 2022. Proposals are due to ARISS by 0759 UTC on April 1.
