MARS HF Net Participants Aid in Response to Fatal Maritime Disaster
On July 6, an evening Army Military Auxiliary Radio System (MARS) HF practice net in Federal Emergency Management Agency (FEMA) Region 2 (New York and New Jersey) was interrupted by several “mayday” distress calls on the channel, which is shared with the maritime service. Net control station Ron Tomo, KE2UK, immediately halted training and attempted (without success) to establish radio communication with the station in distress. Tomo then directed two other net members who heard the distress call — John Hoover, K2XU, and Wayne Gearing, K2WG — to attempt to establish communication and offer assistance.
While the other net members were attempting to contact the vessel by radio, Tomo contacted the US Coast Guard (USCG) station at Jones Beach Island in New York, which alerted the USCG Sector Command at Long Island Sound to join the MARS operators on frequency. MARS operators remained on frequency to assist the USCG in listening for the distress call.
Several hours later, the fishing vessel Falling Star was identified as missing with 15 individuals on board, all from Honduras. Ten days later, the USCG confirmed that 10 of the passengers survived in a skiff and were rescued by a passing commercial oil tanker — the MTM
Amsterdam — which spotted their small craft. Tragically, the skipper of the Falling Star died 1 day before the survivors were found, and was buried at sea.
The vessel was en route from Jamaica to Guatemala when it was reported to have rolled over without warning on July 6, just before midnight.
MARS volunteers alerted the USCG to the vessel in distress several hours before the Falling Star was identified and confirmed as missing. While 10 of those aboard Falling Star were rescued, five others didn’t make it home after this tragic event.
FCC to Re-Establish Technological Advisory Council, Solicits Membership Nominations
The FCC is seeking nominations for a chairperson and members of the Technological Advisory Council (TAC). In a July 21 Public Notice, the Commission announced that it intends to re-establish the TAC for 2 years by August 20, 2021. It’s anticipated that the renewed panel could hold its first meeting in October.
The TAC provides technical advice to the FCC and makes recommendations on the issues and questions presented to it. The panel typically has several radio amateurs among its members. Greg Lapin, N9GL, has represented ARRL on the TAC.
Among other issues, FCC Acting Chairwoman Jessica Rosenworcel will ask the TAC to start looking beyond 5G and conceptualize 6G. In addition, she’ll ask the TAC to study advanced spectrum-sharing techniques, implementation of artificial intelligence, and machine learning to improve the utilization and administration of spectrum and other emerging technologies.
All organizational or individual members appointed to the Council or its working groups are subject to an ethics review by the Commission’s Office of General Counsel. Council members receive no compensation for their service. Nominations for membership must be submitted to the FCC by August 20.
Procedures for submitting nominations are spelled out in the Public Notice, which includes details on membership qualifications and obligations.
The FCC said it’s particularly interested in receiving nominations and expressions of interest from individuals and organizations in these sectors:
“Members will be selected to balance the expertise and viewpoints that are necessary to effectively address the issues to be considered by the Council,” the FCC said.

More Slow-Scan TV Transmissions from RS0ISS Scheduled
Friday and Saturday, August 6 – 7, Russian cosmonauts on board the International Space Station (ISS) will transmit slow-scan television (SSTV) images from the station on 145.800 MHz FM. They will use
SSTV mode PD-120.
The transmissions are part of the Moscow Aviation Institute SSTV experiment (MAI-75) and will be sent via RS0ISS, the ham station in the Russian Zvezda (Service) module using a Kenwood TM-D710 transceiver.
The announced schedule is August 6, 1050 – 1910 UTC; August 7, 0950 – 1555 UTC. Dates and times are subject to change. For stations in the ISS footprint, the RS0ISS signal should be easy to copy on a handheld transceiver and a quarter-wave whip. Use 25 kHz channel spacing, if available.
ITU-R Working Party Considers Preliminary Studies on 23-Centimeter Band
WRC-2 preparatory work for Agenda Item 9.1b continued July 5 – 13 in ITU-R Working Party 4C (WP4C), with a focus on coexistence between the 23-centimeter amateur allocation (1240 – 1300 MHz) and satellite-navigation systems. IARU member representatives from Australia, Brazil, Canada, Germany, Japan, Norway, the UK, and the US participated in the meeting and delivered additional information on amateur activities in this key microwave band.
This Agenda Item is relevant to ITU Region 3 (Europe, Africa, the Middle East, and northern Asia), where one channel of the Galileo GPS system in the Radio Navigation Satellite Services (RNSS) received interference from amateur radio.
Preliminary studies from France were based on the ongoing CEPT (European Conference of Postal and Telecommunications Administrations) effort to provide initial estimates of separation distances required between Galileo receivers and a sample of amateur emissions. The European Commission Galileo team provided a set of observations pertaining to an RNSS interference event in northern Italy.
“The IARU is working to ensure the amateur services are realistically represented in the studies as they move forward,” said Barry Lewis, G4SJH, of the IARU. “It remains vital that national amateur communities present their views on the importance of this band to their national regulators in a consolidated and consistent manner. The work will continue throughout the year and beyond both in ITU-R and in the regional telecommunications organizations, and the IARU is committed to ensure every group hears the amateur position on this important microwave band.”

8-Meter Experimental Station on the Air from the US
WL2XUP is an FCC Part 5 Experimental station operated by Lin Holcomb, NI4Y, in Georgia. It’s licensed to operate with up to 400 W effective radiated power (ERP) between 40.660 MHz to 40.700 MHz.
John Desmond, EI7GL, reports that as of mid-July, WL2XUP was intermittently transmitting on Weak-Signal Propagation Reporter (WSPR) on 40.662 MHz (1500 Hz) for 2 minutes out of every 10, with an output power of 20 W ERP into an omnidirectional antenna. For FT8 check-ins and tests, an ERP of 100 W may be used. The band is affected by several propagation modes, including tropospheric ducting, sporadic E, transequatorial propagation (TEP), and F2 propagation. As Desmond notes, the 40 MHz band will open a lot earlier than 50 MHz and could be a useful resource for stations monitoring the transatlantic path.
A 2019 Petition for Rulemaking (RM-11843) asked the FCC to create a new 8-meter amateur radio allocation on a secondary basis. The Petition suggests the new band could be centered on an industrial-scientific-medical (ISM) segment somewhere between 40.51 and 40.70 MHz. The spectrum between 40 and 41 MHz is currently allocated to the federal government and, as such, within the purview of the National Telecommunications and Information Administration (NTIA).
ARRL member Michelle Bradley, KU3N, of Maryland, filed the petition on behalf of REC Networks, which she founded and described in the Petition as “a leading advocate for a citizen’s access to spectrum,” including amateur radio spectrum.

Amateur Radio Activities to be a Part of Missouri’s State Bicentennial Celebration
The Missouri First Capitol State Historic Site in St. Charles will host an amateur radio event on August 10, in association with this year’s celebration of the Missouri State Bicentennial. The original capitol building on the west bank of the Missouri River served as the state’s capitol from 1821 to 1826. The site is part of the St. Charles Historic District in the city’s Riverfront neighborhood and is adjacent to Frontier Park, from which Lewis and Clark launched their Corps of Discovery Expedition in August 1803.
Members of the St. Charles Amateur Radio Club (SCARC) will use the special event call sign K0B at the site of the First Capitol on August 10. The First Capitol site also qualifies for the Parks on the Air program (POTA) with the identifier K-3349. Additional POTA-style activations from both the First Capitol site and from the adjacent Frontier Park are listed as “possible” on other dates, depending on weather and operator availability.
K0B will be active on SSB, CW, and FT8 on 80 – 6 meters, as well as on 2-meter FM. K0B will also be active from the annual SCARC hamfest and flea market in O’Fallon on August 8 and from SCARC member stations at various times on August 7 – 15. An operating schedule will be posted on the SCARC Facebook page.
Contacts will be uploaded to Logbook of The World (LoTW). A paper QSL and a downloadable PDF certificate will be available.
Members of the Mid-MO Amateur Radio Club will use the special event call sign W0M August 7 – 10, and other Missouri clubs may also be active to commemorate the bicentennial.
The Missouri QSO Party on July 31 – August 1 will also feature special call signs and the activation of rare counties. Typically, the event is held in April.
The Daily DX Editor Bernie McClenny, W3UR, has offered a suggestion for calling DX while using FT8. He advises that FT8 users avoid the “Generated Std Msgs (TX 1)” field when attempting to call DX on FT8. “You can turn it off by double clicking on it,” he said. “When the band opens up, serious DXers want to get in and get out as quickly as possible. We don’t know how long the opening will last, [and] the DX station does not care about your grid locator. You want to get your call sign and report to the DX station as quickly as possible, so you don’t miss the opening. When you are calling a DX station, set the FT8 software to go to message 2 (e.g., TZ4AM KZ3ZZZ -14). Then you want to get the “RR73.” That is all you need for a valid contact. During contests where the grid locator is needed, by all means, send it.”
A Michigan club is considering establishing a common email address for members lacking internet access. Big Rapids Area Amateur Radio Club (BRA-ARC) in Michigan is hoping to establish a common email address so that members lacking a valid email address may receive messages. The impetus for this was the recent FCC requirement that all licensees have an email address on file. “One of our members is in a nursing home, and…we are her family,” said the club’s secretary, Bruce Werner, WB8TVD. “One of our board members suggested club-sponsored personal email, which is forwarded, similar to what is offered by ARRL.” Werner said the club is planning to work out something to accommodate members who have no, or limited, internet access. As ARRL VEC Manager Maria Somma, AB1FM, notes, the FCC simply requires a valid and current email address where the licensee can receive electronic correspondence. She told Werner, “The good news is that it doesn’t matter whose email address is used, as long as the FCC can reach the licensee.” The box would be periodically checked by a club officer, who would contact the member personally.
Swiss radio amateurs are facing a fee to use the QO-100 Satellite. In what might be a first, Switzerland’s telecommunications regulator OFCOM is charging the equivalent of $76.25 to issue special permits to radio amateurs to use the QO-100 (Es’hail-2) amateur satellite transponders. According to a post on the website for the USKA — Switzerland’s IARU member-society — the regulator wishes to protect license-exempt users in the 2.4 GHz industrial, scientific, and medical (ISM) band, and OFCOM reserves the right to withdraw the special permit if problems arise. The special permit entitles the holder to use a transmitter with a maximum output of 100 W PEP for a satellite uplink in the 2400 – 2410 MHz band. As part of their application, radio amateurs must provide coordinates, antenna gain in dBi, antenna height above ground, antenna direction, and a telephone number where the radio amateur can be reached while operating, in addition to the usual name and call sign information.
