Bryan Rawlings, VE3QN, RAC Special Advisor, is in Geneva, Switzerland attending Preparatory Meetings for the 2019 World Radiocommunication Conference (WRC-19) until Friday, November 17.

The current meetings are the fourth of a series of meetings which will continue until just before WRC-19 now scheduled to be held from October 28 to November 22, 2019.

Preparatory Meetings are usually held at the International Telecommunication Union (ITU) headquarters in Geneva and are usually of two weeks duration. This time Bryan is attending as a member of the Canadian Delegation and also as an Expert Consultant for the International Amateur Radio Union (IARU).

Preparatory Meetings primarily prepare documents on the agenda items identified for the upcoming WRC. They are in turn preceded by meetings and the submission of documents from the participating administrations, for example, Canada through its authorized government agency, the Department of Innovation, Science and Economic Development (ISED; formerly Industry Canada). The RAC representative is made a member of the delegation by invitation and Bryan’s role is to advise on Amateur issues.

The principal Amateur Radio issue is an international authorization of the 50 to 54 MHz band in ITU Region 1 (Europe, Africa and the Middle East). Canada has submitted a contribution to this meeting indicating no concerns about interference to the Canadian users who are, of course, Radio Amateurs since 50 – 54 MHz is a Primary Allocation in Canada. Indeed, Canadian Amateurs would welcome harmonization of the six-metre band worldwide.

ITU-R Working Party 5A is chaired by Dr. José Costa, a Canadian, and the Canadian Delegation to WP-5A is being chaired by Ms. Cindy-Lee Cook of ISED.

In addition to Canada, there are Amateur delegates in Geneva this time representing their individual delegations and/or the IARU and they come from the United States, the Netherlands, the United Kingdom, Germany, Japan, Norway, Brazil and Australia.

These meetings are also debating an expansion of the frequencies, powers and deployment of Radio Local Area Networks (RLANs) in the 5 GHz range. Canadian Amateurs have a secondary allocation here in 5650 to 5925 MHz which we already share with the Primary Users – principally meteorological radars – and with ISM (Wi-Fi, etc.).

Also warranting close attention is an agenda item proposing frequencies for wireless power transfer, e.g., charging cellphones and – significantly – larger devices including vehicles. Frequencies under discussion lie in the range 19 to 300 kHz and – possibly – just below the 40m Amateur band. Depending upon the frequencies planned and the technical characteristics there may be significant interference issues to users of the HF and VHF spectrum.

As he has done in recent meetings, Bryan will be tweeting comments on Amateur Radio issues from the meeting using the hashtag #RACatITU. You can also follow him at @VE3QN

Bryan will also be including a report in the next issue of The Canadian Amateur magazine at the conclusion of the meetings.

New AMSAT-NA President Announces GOLF CubeSat Program

AMSAT-NA President Joe Spier K6WAO

AMSAT-NA President Joe Spier K6WAO

At the AMSAT-NA Annual General Meeting in Reno, NV, newly elected AMSAT-NA President Joe Spier, K6WAO, announced the next phase of AMSAT’s CubeSat program: GOLF.

Joe is a Life Member of AMSAT-NA and has previously served as Executive Vice President and Vice-President Educational Relations. He also has Life Memberships in the ARRL, SARA (Society of Amateur Radio Astronomers) and the AFA (Air Force Association). He holds an Extra Class license as well as commercial licenses.

GOLF, an acronym for “Greater Orbit, Larger Footprint,” is a crucial step towards fulfilling AMSAT’s strategic goals involving high altitude, wide access satellite missions.

As an initial step in the GOLF program, the AMSAT-NA Board of Directors approved the submission of a NASA CubeSat Launch Initiative proposal for the GOLF-T satellite project. The GOLF-T project will serve as a rapidly deployable Low Earth Orbit (LEO) testbed for technologies necessary for a successful CubeSat mission to a wide variety of orbits, including LEO, Medium Earth Orbit (MEO), Geosynchronous Orbit (GEO), Highly Elliptical Orbit (HEO), or beyond.

AMSAT-NA Vice-President Engineering Jerry Buxton, N0JY, said “The GOLF-T project tees off the next phase of our CubeSat program. GOLF-T provides AMSAT hardware and knowledge for Attitude Determination and Control (ADAC) capability and the opportunity to develop a 3U spaceframe with deployable solar panels that can be used in LEO or HEO missions, two of the major systems required in future GOLF and HEO missions.”

In addition, GOLF-T provides the opportunity for rapid deployment and on orbit testing of the AMSAT’s Advanced Satellite Communications and Exploration of New Technology (ASCENT )program’s technology, including radiation tolerant transponder and Integrated Housekeeping Unit (IHU) technologies that will lead the way for low cost commercial off-the-shelf (COTS) systems that can function in the MEO and HEO radiation environments. GOLF-T will also provide for the development of “Five and Dime” Field-Programmable Gate Array Software Defined Radio (FPGA SDR) transponders for use on a variety of missions and orbits.

Caution Urged in Using High Duty Cycle Digital Modes via Satellite

Amateur Radio Satellite FO-29

Amateur Radio Satellite FO-29

A report in ANS-288 discussed an experiment operating with the WSJT-X FT8 digital mode via satellite. Satellite operators have gained more experience with this mode over this past week.

As a result of on-the-air observation other satellite users planning to try FT8 or MSK144 modes via satellite are encouraged use caution using these modes and possibly avoid their use completely in light of problems.

Dave, KG5CCI wrote, “He noticed a very hard time getting into the transponder. The pass was nearly overhead, and the 3w-4w that is normally sufficient was barely cutting it. I also noticed it was ‘up and down’ alot, whereas some moments it was easy to get in, then it would be nearly impossible. There were also pockets of ‘noise’ all over the transponder, that sounded somewhat digital, but I just couldn’t place them.” Further investigation revealed that an MSK144 signal in the transponder passband was causing the problems.

Matthew, NJ4Y noted, “Experimentation isn’t the problem, too much power is. It’s bad enough on SSB, worse with CW, and killer on constant duty cycle modes like FT8.”

FalconSAT-3 now open for amateur radio use

FalconSAT-3

FalconSAT-3

The Air Force Academy satellite Falconsat-3 is now open for amateur radio use as a digital store-and-forward system.

FalconSAT-3 DiagramFalconSAT-3 was built in 2005 and 2006 by cadets and faculty in the Space Systems Research Center at the US Air Force Academy in Colorado Springs, CO, and launched in 2007 on an Atlas V.

After serving in scientific and training roles, the Academy has now made the satellite available for Amateur radio use.

The satellite is in a 35.4 degree inclination orbit, with an approximate altitude of 465 to 476 km. The Packet Bulletin Board System is operating at 9600 baud with a 145.840 uplink, and 435.103 downlink. Output power is 1 watt, and the downlink is continuously on. Digipeating is enabled for live QSOs, but unattended digipeating operations is not authorized at this time. Current Keplerian elements can be found in the AMSAT distributed Keplerian elements.

More information can be found at https://www.amsat.org/falconsat-3/

Further operational inquiries should be directed to AMSAT Vice President Operations, Drew Glasbrenner, KO4MA (ko4ma<at>amsat.org).
