Emergency Messaging Demonstration for Red Cross, FEMA is a Success
On May 23, with Red Cross and Federal Emergency Management Agency (FEMA) officials monitoring, dozens of radio amateurs along the US east coast demonstrated Amateur Radio’s ability to deliver messages without commercial power, infrastructure, or permanently established stations. The event took place in coordination with ARRL, as a mock response to a simulated disaster scenario — a major hurricane with mass casualties. During the event, radio amateurs at portable stations from New England to the Carolinas delivered message traffic to W1AW, which coordinated and delivered the information to officials attending a joint Red Cross-FEMA meeting in Baltimore.
“About a dozen stations participated in the demonstration, including operators in Maine, Rhode Island, Massachusetts, New York, northern New Jersey, western Pennsylvania, Delaware, and South Carolina,” ARRL Communications Manager Dave Isgur, N1RSN, said. “Red Cross officials were on-site at W1AW and at the receiving station in Baltimore. At both sites, they indicated that were impressed with Amateur Radio’s ability to deliver messages digitally so that could be displayed on a computer screen and in a format that matched the format for messages that the Red Cross uses.” Isgur said ABC, CBS, and Fox TV affiliates sent reporting teams to W1AW.
A few stations, including W1AW and stations in Baltimore, generated local media coverage of their participation, much of it tied into the notion of “Amateur Radio operators and the partner agencies they serve are getting ready for the 2018 hurricane season,” which begins on June 1 and continues through November 30.
W1AW Station Manager Joe Carcia, NJ1Q, said the exercise went well overall. “Conditions were a bit tepid at best, but we were able to establish voice contact first, and then proceed with the digital traffic (MT63-1KS) during the roll call,” Carcia said. “Digital signals were good. I needed just one retransmit. We used fldigi with flmsg. This made life so much easier.”
Ohio ARES Activates in Wake of Tornadoes that Badly Damaged Hara Arena
Hara Arena, in Trotwood, Ohio, which served as the home for Dayton Hamvention® for more than 6 decades, was among the structures extensively damaged when tornadoes swept through the Dayton area on Memorial Day. WHIO-TV drone video showed that the roof and side of the structure had been blown off in several places by the EF3 (severe-scale damage) event. Ohio Section Emergency Coordinator Stan Broadway, N8BHL, said ARES counties and districts activated after nearly 40 tornado warnings were issued across the state. He said Ohio ARES was in the process of announcing a partnership with the Ohio Emergency Management Agency Watch Desk, in which some 2,000 Ohio radio amateurs will feed situation awareness to the state.
The severe weather struck after dark, causing widespread damage in and around Dayton and elsewhere in the Miami Valley. Multiple injuries and one fatality have been reported. It appears that at least two tornadoes were responsible for most of the devastation, which was called “catastrophic.” The NWS office in Wilmington, Ohio, estimated that at one point, storms and tornadoes left some 5 million people without electrical power.
Snow plows were repurposed to remove debris from Interstate Route 75, and the American Red Cross set up shelters to accommodate displaced residents.
“First-tier communications remained solid in most of the affected areas,” Broadway recounted, “but amateur operators were able to provide situational awareness that enhanced the response.” Most ARES activities in Ohio wrapped up on May 29.
WHIO-TV reported on June 5 that structural engineers were still assessing the damage at Hara Arena, but Michael Heitz, the Kentucky developer who now owns the building and the surrounding 120 acres, has expressed confidence that the main arena can be saved, although an attached section will have to be demolished.
Hurricane Michael Investigation Digs into Factors that Hindered Wireless Services Recovery
On May 9, the FCC’s Public Safety and Homeland Security Bureau released a report on its investigation into communications providers’ preparation for and response to Hurricane Michael last October. An array of Amateur Radio public service assets was active as Hurricane Michael made landfall near Mexico Beach on the Florida Panhandle, boasting devastating 155 MPH winds. The storm was the first Category 4 or stronger hurricane to hit the Florida Panhandle since 1992.
“There were numerous cases in which a wireless provider had restored service to customers only to have that service brought down as third-party crews damaged communications assets while clearing trash or restoring power lines and utility poles,” the FCC recounted in a news release.
To improve recovery efforts from future storms, the report recommended, among other things, that wireless providers use diverse backhaul options, such as microwave links and satellite links in hurricane-prone areas, and that communication providers participate in training to improve coordination of restoration efforts.
The Hurricane Michael Report is available at on the FCC website. — FCC News Release

New FT4 Beta Release “Leaps and Bounds” Better than Earlier Iterations
The WSJT-X Development Group released yet another new beta version of the FT4 protocol this week, and WSJT-X 2.1.0-rc7 is now available for testing. Developers point out that the FT4 included in this “release candidate 7” version is not compatible with any previous releases. A short mock contest session to wring out the contesting features of FT4 took place on June 4.
Based on data compiled by Steve Franke, K9AN, Taylor said that it appears developers have the WSJT-X timing behavior under good control on all supported platforms, and the range of measured signal-to-noise values extended down to -21 dB.
“I operated for about 3 hours using 100 W and a dipole,” Taylor recounted. “I copied transmissions from 263 unique call signs and made 143 QSOs in 29 states, 5 Canadian provinces, and 15 DXCCs.”
Taylor said the developers anticipate addressing all remaining issues they’re aware of. “I believe we are on a good path toward a General Availability (GA) release of WSJT-X 2.1.0 by mid-July,” he said.
“This new version of FT4 is leaps and bounds better than before,” said Mike Black, W9MDB, in a June 4 post to the Yahoo WSJT Meteor Scatter and Weak Signal Group. “I worked almost everybody I could see without any repeats. Seems like we have a winner here.”
Changes, improvements, and bug fixes that have been made since WSJT-X 2.1.0-rc5 include:
Release candidate WSJT-X 2.1.0-rc7 will be available for beta-testing through July 21, and it will permanently cease to function after that date. It will not be usable during the ARRL June VHF Contest or during ARRL Field Day. Taylor advised using WSJT-X 2.0.1 and FT8 for these events.
Downloadable installation packages for WSJT-X 2.1.0-rc7 under Windows, Linux, and macOS are available on the WSJT-X web page.
China Set to Launch New Amateur Satellite with “Sail Ball” Stabilization
Chinese Amateur Satellite Group (CAMSAT) has announced the impending launch of the CAS-7B satellite, also designated as BP-1B, a short-lived spacecraft that will carry an Amateur Radio payload. An unusual feature of the spacecraft is its “sail ball” passive stabilization system. The 1.5 U CubeSat is attached to a 500-millimeter flexible film
The spacecraft will carry an Amateur Radio transponder and educational mission. CAMSAT is working with the Beijing Institute of Technology (BIT), a top aerospace school, which is providing launch support. BIT faculty and students are participating in the development and testing of the satellite, and, with CAMSAT’s help, the university has established an Amateur Radio club (BI1LG). CAMSAT said many students are now members, “learning Amateur Radio satellite communication and [experiencing] endless fun.”
The VHF and UHF antennas are quarter-wave monopoles. CAS-7B will transmit a CW telemetry beacon on 435.715 MHz. The V/U FM voice transponder downlink will be 435.690 MHz, and the transponder uplink will be 145.900 MHz (16 kHz passband).
The 3-kilogram satellite will have an apogee of 300 kilometers.
“Because of the orbital apogee and the size and mass of the satellite, the orbital life is expected to be only 1 week, up to a maximum of 1 month, which will also provide an opportunity for hams to track and monitor satellite entering the atmosphere,” CAMSAT said in announcing the new satellite, scheduled for launch late this month.
“The launch will use a new launch vehicle from a small commercial rocket company,” CAMSAT explained. “This is the first launch of this launch vehicle, and there is a large possibility of failure; if the launch fails, we will have another launch later this year.” — Thanks to Alan Kung, BA1DU/CAMSAT
Mexican Amateur Radio Volunteers Provide Communication in Wildfire Response
Mexican radio amateurs provided communication support in late May from a fire scene in a remote area to civil protection authorities in Monterrey, Mexico. Two-member teams of volunteers were flown in via helicopter since May 20, the first day of radio support, when the fire had already been burning for a couple of days. The fire in Pajonal — about 20 kilometers south of Monterrey — covered more than 200 acres in rough terrain. Temperatures topped 100 °F.
Teams had been using Winlink but added the weak-signal software Vara HF, after José Alberto Nieto, EA5HVK, provided a Vara license on short notice. Tom Whiteside, N5TW, in Georgetown, Texas, supported the effort from across the border, aiming his 40- and 20-meter arrays in the direction of the fire in Nuevo Leon. Alfonso Tamez, XE2O, president of Mexico’s IARU member-society Federación Mexicana de Radioexperimentadores (FMRE), was been among the volunteers.
In addition to HF digital traffic, the volunteer teams took advantage of VHF repeaters. HF antennas consisted of a 40-meter dipole for 40 and a steerable portable dipole. A generator is providing electrical power.
The K7RA Solar Update
Tad Cook, K7RA, Seattle, reports: According to Spaceweather.com, as of June 5 there have been no sunspots for 17 days in a row. Average daily solar flux went to 69.5 for the May 30 – June 5 reporting week from 67.4 in the previous 7 days. The average daily planetary A index declined from 7.3 to 5.6, while the mid-latitude A index dipped from 8.1 to 5.

AMSAT, ARISS Veteran Keith D. Pugh, W5IU, SK
AMSAT and ARISS engineering veteran, Keith Pugh, W5IU, of Fort Worth, Texas, died on May 24. An ARRL Life Member, he was 80.
Born and raised in Dodge City, Kansas, Pugh was licensed in 1953. Amateur Radio strongly influenced his decision to pursue a career in electrical engineering, and he earned a Bachelor of Science in electrical engineering at Kansas State University in 1961. He moved to Texas to work for Convair (later General Dynamics and Lockheed Martin), and, after upgrading to an Amateur Extra-class license, he became W5IU. Pugh retired from Lockheed Martin in 2004 after a career in RADAR and Navigation Systems Engineering.
In the early 1980s, he became interested in ham radio satellites, making contacts on AO-08 and AO-10. He went on to become an AMSAT Area Coordinator and, later served as AMSAT Vice President for Operations.
Pugh jump-started his passion for Amateur Radio on human spaceflight missions in 1991, when the Soviet space station Mirwas in orbit. Pugh joined the Amateur Radio on the International Space Station (ARISS) team in 2004, where he has provided support as an operations leader, mentoring numerous schools and ARISS contact organizations and attending ARISS International meetings.
ARISS ARRL Representative Rosalie White, K1STO, said Pugh made a difference in his role as an ARISS Technical Mentor for many schools. “ARISS contacts are always exciting and sometimes produce tense moments,” White said. “He touched hundreds of thousands of youth along with all ages of people who had curiosity about ham radio, space, and satellites.”
