IARU Holds First 2023 Meeting

The 56th meeting of the Administrative Council of the International Amateur Radio Union (IARU) was held via Zoom on January 16, with President Tim Ellam, VE6SH, presiding.

The council received reports from the officers of each of the three regions. The meeting’s focus was on the International Telecommunication Union’s (ITU) upcoming World Radiocommunication Conference (WRC-23) later this year in Dubai, United Arab Emirates. The IARU effort for WRC-23 is being led by IARU Vice President Ole Garpestad, LA2RR.

Here is a summary of the meeting submitted by IARU Secretary Joel Harrison, W5ZN:

“Of particular interest to the amateur radio and amateur satellite services for WRC-23 is agenda item 9.1b concerning the amateur allocation in the 23 – centimeter band at 1240-1300 MHz. The Radio Navigation Satellite Service (RNSS) is seeking protection from secondary users in addition to an expanded allocation. Preparatory work for this item is being conducted within the ITU’s Working Party 5A. IARU’s global WRC-23 9.1b team, led by Barry Lewis, G4SJH, has been consulting with the amateur community, resulting in a contribution to the draft guidance recommendation in support of coexistence with RNSS. Details on this work can be found at

The council reviewed a comprehensive written report from IARU [Electromagnetic Compatibility] Coordinator Dr. Martin Sach, G8KDF, on his work with the International Special Committee on Radio Interference (CISPR). CISPR was formed in 1934 to set standards for controlling electromagnetic interference in electrical and electronic devices. CISPR’s specific areas include radio interference measurements and statical methods, and limits for the protection of radio frequencies.

An ongoing strategic planning review of the current IARU structure is being conducted within several Working Groups (WGs). The Administrative Council received reports from the Futures WG Steering Committee, Relationship WG, Governance WG, and the Legal WG. This work is scheduled for completion no later than July to allow discussion at the Region 1 [General] Conference in Serbia in October, with additional opportunities provided to the other two regions.

Region 1 has received several inquiries regarding the status of [John Devoldere’s,] ON4UN, and [Mark Demeuleneere’s,] ON4WW, book, Ethics and Operating Procedures for the Radio Amateur and is considering how this document [can] be updated.

The Summary Record from this meeting, in addition to previous meetings, is available at”

The next virtual meeting of the Administrative Council is scheduled for March 20, and an in-person meeting is scheduled for June 25 at the conclusion of Ham Radio in Friedrichshafen, Germany.

The members of the IARU Administrative Council are the President, Vice President, Secretary, and two members from each of the regional organizations. Members participating in this meeting were IARU President Tim Ellam, VE6SH/G4HUA; Vice President Ole Garpestad, LA2RR; Secretary Joel Harrison, W5ZN; IARUI Region 1; George Gorsline, VE3YV, President, and Rod Stafford, W6ROD,Sylvain Azarian, F4GKR, President, and Mats Espling, SM6EAN, Secretary, IARU Region 2; George Gorsline, VE3YV, President, and Rod Stafford, W6ROD, Secretary, and Region 3; Chairman Ken Yamamoto, JA1CJP, and Director Yudi Hasbi, YD1PRY. Assistant Secretary David Sumner, K1ZZ, also participated.

Founded in 1925, IARU is the worldwide voice of radio amateurs who secure and safeguard the amateur radio spectrum. ARRL serves as the International Secretariat of IARU.

AMSAT IT Tackles TLE Problem

AMSAT IT, in conjunction with the New England Sci-Tech STEM Education Center assembled a tiger team of software experts from the Olin College of Engineering, Boston Latin School and the Wilson Middle School to investigate the recent disappearance of AO-7 from and the legacy naasbare.txt files.

The team determined that AMSAT’s processing is not robust in the face of minor format differences in the source data received from the USSF’s 18th Space Defense Squadron. Specifically, the TLE data provided does not always include the leading zero in AO-7’s object number “07530”. The official report from the team’s leader: “My grandma would say that AMSAT’s software is just a little too persnickety.”

A member of the tiger team agreed to adjust the update script to account for the vagaries of the 18th SDS data. A production quality fix is expected by March 1. Meanwhile, manual monitoring and updates will keep AO-7 in the files.

SpaceX Dragon Will Carry More Hams to ISS

NASA will provide coverage of the upcoming prelaunch and launch activities for the agency’s SpaceX Crew-6 mission with astronauts to the International Space Station.

Launch is targeted for 07:07 UTC, Sunday, Feb. 26, from Launch Complex 39A at NASA’s Kennedy Space Center in Florida. The Dragon spacecraft is scheduled to dock to the space-facing port of the station’s Harmony module at 07:54 UTC, Monday, Feb. 27.

The Crew-6 launch will carry two NASA astronauts, Mission Commander Stephen Bowen, KI5BKB, and Pilot Warren “Woody” Hoburg, KB3HTZ, along with UAE (United Arab Emirates) astronaut Sultan Al Neyadi, KI5VTV, and Roscosmos cosmonaut Andrey Fedyaev, who will serve as mission specialists to the space station for a science expedition mission.

This is the sixth crew rotation mission with astronauts using the SpaceX Dragon spacecraft on a Falcon 9 rocket to the orbiting laboratory as part of the agency’s Commercial Crew Program. This Dragon is named Endeavour.

NASA TV launch coverage begins on Sunday, Feb. 26 at 03:30 UTC (10:30 p.m. EST).

Balloon Experimenters Worry About Reactions

Balloon hobbyists are also worried that the small balloons they launch into the sky could be shot down or that the focus on balloons could lead to tight restrictions on their little-known hobby.

Speculation has grown about whether one of the unidentified objects taken down by a U.S. F-22 on Feb. 11 over Canada’s Yukon Territory was a small party-style balloon launched by a hobby group whose name is a whimsical reference to the children’s film “Up.” The Northern Illinois Bottlecap Balloon Brigade recently said one of its balloons went “missing in action” on Feb. 11, near an island off the coast of Alaska.

People launch balloons for radio experiments, or as part of projects to learn more about technology, balloons, and the sky — as well as for fun, according to Dave Akerman, a member of the U.K. High Altitude Society who has launched nearly 100 larger latex balloons. Now enthusiasts are concerned “there will be a knee-jerk reaction to what’s happened,” he said in an interview.

He said he hoped that authorities and hobbyists could coordinate on reasonable guidelines or rules if needed. “It’s also in the interests of authorities not to be shooting down party balloons with missiles.”

Changes to AMSAT-NA TLE Distribution for February 19

Two Line Elements or TLEs, often referred to as Keplerian elements or keps in the amateur community, are the inputs to the SGP4 standard mathematical model of spacecraft orbits used by most amateur tracking programs. Weekly updates are completely adequate for most amateur satellites. TLE bulletin files are updated Thursday evenings around 2300 UTC, or more frequently if new high interest satellites are launched. More information may be found at

The following satellites have decayed from orbit and have been removed from this week’s AMSAT-NA TLE distribution:

CP-7 DAVE NORAD Cat ID 43615 (decayed from orbit on 02/12/23 per Space-Track).
NO-104 (PSAT-2) NORAD Cat ID 44354 (decayed from orbit on 02/15/23 per Space-Track).

Satellite Shorts From All Over

+ The Pehuensat-1 or PO-63, the hamradio payload made by Universidad del Comahue, Argentina that was attached to the structure of an Indian PSLV rocket, re-entered Earth atmosphere on January 16, 2023 according to Space_Track. (ANS thanks Gustavo Carpignano, LW2DTZ, for the above information)

+ As reported above, NO-104 (PSAT-2) decayed from orbit on 02/15/23. The Technical University of Brno in Brno, Czech Republic wishes to thank again Bob Bruninga WB4APR(SK) who allowed us to build the PSK transponder and to add the SSTV camera to the project undertaken by the U.S. Naval Academy. “We had lot of fun during experiments! Both transponder and camera operated flawlessly till the battery deterioration. Hopefully some future satelite builder will be interested in those space tested blocks.” (ANS thanks Tomáš Urbanec, OK2PNQ, of Technical University of Brno, for the above information.

+ A new Indian rocket successfully delivered three satellites to orbit on Thursday, Feb. 9, including Janus-1, which was built by the Indian-American company Antaris, is a technology-demonstrating “smart satellite,” according to the ISRO mission description. Like its predecessor, AzaadiSAT-2 was built by hundreds of female students from across India. AzaadiSAT-2 “aims to demonstrate LoRa and amateur radio communication capabilities, measure radiation levels in space and demonstrate expandable satellite structure, etc,” ISRO officials wrote. (ANS thanks for the above information)

+ Even as Russia’s Progress MS-22 arrived at the ISS, the uncrewed ​​Progress MS-21 cargo craft lost pressure—this vehicle isn’t used for crew return and will be disposed of in a fiery reentry anyway, but it doesn’t increase confidence in aging ISS and Russian hardware—meanwhile, Russia is planning to launch a replacement for their other failing ISS vehicle, Soyuz MS-22, on Sunday, Feb. 19. (ANS thanks The Orbital Index for the above information)

+ As SpaceX tests a vehicle that will be capable of 100 tons to LEO (and, eventually, as much as 150 t), and continues a record-setting Falcon launch (and pad turnaround) cadence, the industry is talking about “bloodletting” and how other launch companies can’t compete with the $275,000 that SpaceX charges to take a 50 kg smallsat to Sun-Synchronoous Orbit (SSO) on a Transporter mission.
