ARES Activates as Wind-Driven Year-End Fire Destroys 1,000 Colorado Homes

Members of the Amateur Radio Emergency Service® (ARES®) in Colorado, volunteering for the Boulder County (Colorado) Amateur Radio Emergency Services (BCARES), turned out on December 30, 2021 as the devastating Marshall Fire roared through Superior and (portions of) Louisville, Colorado. Intense winds whipped a grass fire south of Boulder near Marshall into a massive firestorm that became too large and fierce for firefighters to battle.

"The only battle was evacuation, as the towns of Louisville and Superior and [the] northern suburbs of Denver lay in the fire's wind-driven path," said Amateur TV (ATV) enthusiast and equipment dealer Jim Andrews, KH6HTV, of Boulder. Andrews said the only thing limiting the fire's spread was the fact that the winds diminished by that evening.

"By that time, hundreds of homes had burned down," Andrews said, whose own house was among them. "This was not a typical forest fire, but an urban firestorm." Thousands of people were evacuated.

BCARES Board of Directors Chairman and Region 1, District 3 Emergency Coordinator Allen Bishop, K0ARK, said that a request from the Boulder Office of Emergency Management (OEM) to activate the emergency operations center (EOC) is what initiated the ARES activation. "At that time, staffing was initiated with the activation of the BCARES Radio Network, with three BCARES members assigned to the EOC," Bishop said. The BCARES Net was promptly activated.

ARES volunteers supported communication at evacuation sites and established emergency communication as commercial power failures and preventive shutdowns by utilities caused a loss of commercial communication. "Within about 8 hours," Bishop said, "battery back-up systems for cell phones and landlines failed, and 911 services went down."

"To facilitate a restoration of these emergency services, BCARES activated the Mountain Emergency Radio Network (MERN)," Bishop said. Established in 2010, MERN consists of repeaters installed at fire stations in Gold Hill and Allenspark, at community centers in Nederland and Raymond, and the privately owned Airlink Repeater. "These repeaters provided the emergency communication links that facilitated the restoration of 911 communications back to the dispatch center for the duration of the power outages," Bishop explained. The Allenspark Neighbors Emergency Network (ANEN) and Airlink (Alternate Access Radio Network) participated.

According to Bishop, as the Marshall Fire expanded, evacuation center support was requested at three locations to provide on-site situation reports using Winlink. Bishop said BCARES members and mutual-aid ARES operators from neighboring Districts established local communication with the BCARES EOC radio position from designated field locations. BCARES was activated for 2 days. One person died as a result of the fire.

As Andrews reported, Boulder County announced on New Year's Day that nearly 1,000 homes were lost. In addition to his own home, the fire destroyed his daughter's home next door, as well as the homes of all his close neighbors. "We had no official warning of the coming firestorm," Andrews said. "My only warning was from our daughter who saw it happening." Andrews added, "KH6HTV VIDEO, as a supplier of ATV gear, will be out of operation for a very long time to come." Andrews edits the monthly Boulder Amateur Television Club TV Repeater's REPEATER newsletter.

Extended ARRL Team Will Support February's ARRL National Convention in Orlando

An extended ARRL team of member-volunteers, program representatives, and presenters will advance the convention theme inviting attendees to "reDiscover Radio" at Orlando HamCation, host of the 2022 ARRL National Convention February 10 - 13. A wide-ranging roster of workshops, exhibits, and activities will educate and entertain radio amateurs committed to developing knowledge and skills in radio technology and radio communication.

The convention will be held in two parts. On Thursday, February 10, an all-day ARRL National Convention Program will be held at the DoubleTree by Hilton Hotel Orlando at SeaWorld. Advance registration is required and includes a series of day-long ARRL Training Tracks and a National Convention luncheon with a keynote address by ARRL CEO David Minster, NA2AA. The Training Tracks comprise four workshops led by experienced presenters: Contest University (CTU), Emergency Communications Academy, Hands-On Handbook, and Technology Academy. Registration can be completed online.

DX Engineering is the Official Sponsor of the 2022 ARRL National Convention Program.

On Friday, Saturday, and Sunday, February 11 - 13, HamCation will take place at the Central Florida Fairgrounds and Expo Park in Orlando -- an 87-acre lakefront fairgrounds. The convention marks the 75th anniversary of HamCation -- one of the largest annual gatherings of radio amateurs in the US. HamCation tickets can be purchased online until January 31 and at the gate during the event.

The centerpiece of ARRL's participation will be a large exhibit area in the East and West Hall. Nearly a dozen ARRL program areas will be represented, including Radiosport and DXCC Card Checking, Radio Clubs, the Amateur Radio Emergency Service®, Development, and the ARRL Foundation.

A suite of exhibits organized by the ARRL Education and Learning Department will include an introduction to the new ARRL Learning Center.

National Science Foundation Awards Nearly $50,000 for HamSCI Workshop

Nathaniel Frissell, W2NAF, an assistant professor at The University of Scranton Department of Physics and Electrical Engineering, has received a National Science Foundation (NSF) grant of nearly $50,000 to support the 2022 Ham Radio Science Citizen Investigation (HamSCI) Workshop. The event is set for March 18 - 19 at The US Space & Rocket Center® in Huntsville, Alabama. The in-person conference also has a virtual format option.

HamSCI is a collective of professional researchers and radio amateurs with the objective of fostering collaboration between the amateur and professional communities to advance scientific research and understanding, encourage development of new technologies to support this research, and provide educational opportunities for both the amateur radio community and the general public.

The workshop will serve as a team meeting for the HamSCI Personal Space Weather Station project, the beneficiary of a $1.3 million NSF-funded project grant awarded to Frissell. That project seeks to harness the power of a network of radio amateurs to better understand and measure the effects of weather in the upper levels of Earth's atmosphere. The theme for the 2-day HamSCI workshop is "The Weather Connection." The fifth annual workshop will feature prominent leaders in space weather, atmospheric weather, and the connection between them.

"The workshop series has led to cutting-edge work in the fields of space physics, citizen science, and the use of crowd-sourced ionospheric data," Frissell said. "To maximize the potential of the ham radio-professional researcher relationship, meetings are needed to bring these groups together to learn about each other's communities [and] vocabularies, to share ideas, and to participate in activities that advance both the scientific field and the radio hobby."

Frissell's research focuses on the ionosphere, the atmospheric region that extends 50 - 600 miles above Earth's surface. According to Frissell, changes in the ionosphere alter the behavior of radio wave propagation and greatly affect the radio communications and global navigation satellite systems. "Understanding ionospheric structures and processes will lead to an increased understanding and prediction of these effects," he said. Frissell said he's still seeking presentation abstracts for the workshop. Submit abstracts using the form on the HamSCI Workshop page.

  • The ARRL Board of Directors' Annual Meeting will get under way on Friday, January 21, and continue into the next day. Topping the agenda is the election of officers, including President, Vice Presidents, Secretary, Treasurer, CEO, CFO, Executive Committee, and ARRL Foundation Directors.

  • FEMA's Emergency Management Institute (EMI) will offer the K0428 CERT Train-the-Trainer course online. This course prepares participants to deliver FEMA's CERT Basic Training course. For additional information, contact Jamie "Betsy" Mauk, EMI Course Manager. Refer to the EMI website for course date availability.

  • The YOTA (Youngsters on the Air) Contest Committee has released claimed scores for the third round of the 2021 YOTA Contest.

  • The State QSO Party website has been updated. It includes the 2022 rules for the SQP Challenge and Worked All QSO Parties, the SQP calendar, an updated 2022 WAQP submission form, and the addition of the Quebec QSO Party to the approved list of QSO parties. -- Thanks to Stan Zawrotny, K4SBZ

  • Pete Smith, N4ZR, announced that the Reverse Beacon Network (RBN) node at TI7W is up and running. The node fills a gap in the RBN network's coverage, as it is the first in Central America.

FCC Seeks Attorney-Advisor for its Mobility Division

The FCC has posted an opening for an attorney-advisor in the Mobility Division of its Wireless Telecommunications Bureau in Washington, DC. As a principal attorney with mid-to-senior level responsibilities, the individual's job duties would include working on policy, rulemaking, and legal issues; drafting Commission- and Bureau-level rulemaking and adjudication decisions, and reviewing proposed legislation, rulemakings, orders, and changes to regulations.

According to the FCC website, the Mobility Division is "responsible for developing policy and rules that facilitate rapid, widespread deployment of wireless communications services. Along with the Broadband Division, it oversees nearly 2 million licenses used to provide an array of wireless services. The Mobility Division helps carry out the [Broadband Personal Communications Service], to private land mobile used for dispatch and remote monitoring of equipment, to maritime and aviation, to personal use such as ham radio."

ARRL CEO David Minster, NA2AA, has suggested that the position listing be shared by ARRL members who know an attorney interested in communications law and who has an amateur license. "This non-supervisory position is at the top of the government pay scale. I would urge any amateur who is an attorney and has several years of experience to apply -- especially if they are interested in wireless," Minster said. The deadline to apply for this opening is January 28, 2022.

Launch of a Wooden Satellite Still Pending

Two spacecraft comprised of wood or using wooden framing are hoping to launch this year and next. One will carry an amateur radio payload.

WISA Woodsat, a Finnish spacecraft that planned to include an amateur radio payload, was forced to postpone its announced launch target from 2021 to 2022 after the International Amateur Radio Union (IARU) Amateur Satellite Frequency Coordination system turned away its request to use amateur radio frequencies.

"I regret to inform you that IARU is not in a position to support the WISA Woodsat Coordination request," the coordinator said. "The main reason is that the primary mission doesn't seem to be an amateur mission."

As announced last year, WISA Woodsat was designed to accommodate multiple missions -- from materials science, space education, and awareness to promoting and facilitating amateur radio communication with and via satellites. No transponder was on board, but the satellite's sponsors said they had the support of Finland's IARU member-society, SRAL, to use amateur radio frequencies. They are now reworking the spacecraft to use commercial radio frequencies.

Meanwhile, LignoSat, a 1U-sized CubeSat with an outside structure mainly composed of wood, has applied for IARU frequency coordination and hopes to launch from the ISS in 2023. Built by students at Japan's Kyoto University, LignoSat includes a unique amateur radio payload but not a transponder.

The LignoSat application for IARU Satellite Frequency Coordination in December said the CubeSat would carry amateur radio equipment that will extract call signs of amateur radio stations from uplinked FM

packet signals and respond to them via the CW downlink and the sender's call signs to convey thank you messages. The plan proposes UHF downlinks for CW and FM.

The satellite's development team, comprised of Kyoto University and Sumitomo Forestry Company, said it's aiming to harness the environmental friendliness and the economy of wood in spacecraft development. They say a satellite with a wooden exterior would burn up upon re-entering Earth's atmosphere at the end of its mission, lessening its burden on the environment. The wooden framework also will permit the satellite's antennas to be inside the spacecraft. A plan is under way to use an experimental apparatus on the International Space Station to hold wooden sheets of varying hardness, taken from several tree species, attached. These would remain exposed to the space environment for about 9 months to determine their deterioration.

LignoSat would be deployed from the ISS in July 2023. Read an expanded version. -- Thanks to Joey Ferguson, W4JF, and Japan Times.

Two Radio Amateurs Appointed to the FCC Technological Advisory Council (TAC)

FCC Chairwoman Jessica Rosenworcel named two prominent radio amateurs among her appointments to the FCC Technological Advisory Council (TAC) on January 19. Appointed were Greg Lapin, N9GL, and Michelle Thompson, W5NYV. Lapin chairs the ARRL RF Safety Committee and has represented ARRL The National Association for Amateur Radio on the TAC since 2001.

Greg Lapin, N9GL

ARRL Laboratory Manager Ed Hare, W1RFI, noted that Lapin has been involved with RF safety and the FCC since the last FCC significant rules changes in 1998," he said. "He is again helping the FCC prepare information on OET Bulletin 65, Supplement B for amateur radio, giving guidance for amateurs who need to comply with the FCC rules on RF exposure. His work is highly respected by the FCC and the ARRL Lab, making it easier for amateurs to evaluate their stations."

Michelle Thompson, W5NYV

Thompson is CEO of the Open Research Institute (ORI), which she will represent on the TAC. ORI is a non-profit research and development organization dedicated to open-source work that includes such areas as amateur satellites and digital communications. She is an ARRL Life Member. Thompson will discuss "Digital Communications Technology" on February 10 at the ARRL National Convention in Orlando, as part of the Technology Academy workshop Track.

The TAC serves to assist the FCC in identifying important areas of innovation and developing informed technology policies that support US competitiveness in the global economy. The TAC will consider and advise the FCC on topics such as 6G, artificial intelligence, advanced spectrum-sharing technologies, and emerging wireless technologies, including new tools to restore internet access during shutdowns and other disruptions. The TAC will hold its first meeting of the year on February 28.

In Brief...

A new Section Manager has been appointed for Northern New York. Thomas Dick, KF2GC, Section Manager for the ARRL Northern New York Section, has stepped down after serving, first from 2000 - 2006 and again from 2009 - present. ARRL Field Services Manager Mike Walters, W8ZY, has appointed Rocco Conte, WU2M, of Gloversville, New York, to succeed him on an interim basis. Conte has served as an Assistant Section Manager and District Emergency Coordinator for the last several years. His appointment became effective January 17, 2022.

Amateur operation in the 3.45 - 3.5 GHz of 9 centimeters must cease by April 14, 2022. Secondary operations will be permitted to continue indefinitely in the remainder of the band, 3.3 - 3.45 GHz, pending future FCC proceedings. On January 14 the FCC released DA 22-39, which announces the results of Auction 110 for the 3.45 - 3.55 GHz band. Release of this notice triggered FCC rules adopted last year requiring that amateur radio operations between 3.45 GHz and 3.5 GHz cease within 90 days of the public notice. In October 2021, ARRL President Rick Roderick, K5UR, urged Congress to direct the FCC to preserve Amateur Radio's secondary use of the 3 GHz band in a written statement responding to H.R. 5378, the Spectrum Innovation Act of 2021, before the US House Commerce Communications and Technology Subcommittee. A chronology of actions responding to amateur access on the 3.5 GHz band can be found on the ARRL website.

The K7RA Solar Update

Tad Cook, K7RA, Seattle, reports: Solar and geomagnetic activity increased this week. The average daily sunspot number rose by 52 points, from 42.4 to 94.4. The sunspot number peaked at 120 last Saturday.

Average daily solar flux went from 101.6 to 112, peaking at 119.4 on Sunday. Average daily planetary A index rose from 6.1 to 15.6, and average middle latitude numbers went from 4.1 to 11.3.

As reported by, sunspot AR2929 erupted at 1744 UTC on January 18 with an M1.5 class solar flare, blasting a pulse of X-rays and causing a shortwave radio blackout. I observed the blackout while using FT8 on 10 meters to observe propagation using Just before the blast I could see my 10 meter signal reported by stations on the East Coast, but suddenly I saw no reports. The surprising part was during that period no local stations could copy my signal either!

Predicted solar flux is 102, 98, 94 and 92 on January 20 - 23; 90 on January 24 - 26; 100 and 95 on January 27 - 28; 90 on January 29 - 30; 95 on January 31; 100 and 105 on February 1 - 2; 110 on February 3 - 10; 115 on February 11 - 14; 110, 108, and 106 on February 15 - 17; 102 on February 18 - 21; 100 on February 22 - 23; 95 on February 24, and 90 on February 25 - 26. Flux values may rise to 110 after March 2.

Predicted planetary A index is 16 on January 20; 8 on January 21 - 22; 12 on January 23; 8 on January 24 - 26; 5 on January 27; 10 on January 28 - 30; 5 on January 31 - February 3; then 15 and 10 on February 4 - 5; 5 on February 6 - 9; 12, 15, 12, 18, and 10 on February 10 - 14; 5 on February 15 - 19; 8 on February 20 - 22; 5 on February 23, and 10 on February 24 - 26.

Sunspot numbers for January 13 - 19 were 111, 112, 120, 103, 99, 59, and 57, with a mean of 94.4. The 10.7-centimeter flux was 105.5, 110.2, 115.6, 119.4, 113.5, 114.5, and 105.3, with a mean of 112. Estimated planetary A indices were 3, 15, 22, 19, 9, 18, and 23, with a mean of 15.6. Middle latitude A index was 3, 10, 17, 16, 6, 12, and 15, with a mean of 11.3.
