AMSAT Gearing Up for Hamvention

With barely one month to go, AMSAT volunteers are busy getting ready to return to the Dayton Amateur Radio Club Hamvention. Running from May 20 to 22, 2022, this will be the 70th Anniversary of the legendary Amateur Radio get-together. After a two-year hiatus caused by the COVID pandemic, everyone is anxious to return to examine the latest in technology and to visit with old friends. As before, Hamvention will be held at the Greene County Fairgrounds and Expo Center in Xenia, Ohio.

AMSAT’s presence will be felt in with eight adjoining booths in Building 1. Highlighting the exhibit will be:

– CubeSat Simulator hardware and software demonstrations
– SatPC software demonstrations
– AMSAT Engineering staff question and answer table
– AMSAT Youth Initiative (KidzSat) introduction
– OSCAR ground station for live satellite operations
– Annual Membership sign-up and renewals
– AMSAT President’s Club recognition
– AMSAT Board of Directors and Senior Officers Meet and Greet
– AMSAT Store offering AMSAT trinkets, books and Arrow Antennas

Everyone is also invited to two special evening events:

– The annual “Dinner at Tickets will be held on Thursday evening at 6:00 PM at Tickets restaurant located at 7 W Main St, Fairborn, Ohio.
– The AMSAT/TAPR Annual Banquet will be held Friday night at 6:30 PM at the Kohler Presidential Banquet Center located at 4548 Presidential Way, Kettering, Ohio. Tickets are $57 and must be ordered in advance at the AMSAT Store no later than May 13, 2022.

Additionally AMSAT will also host its annual member forum at Hamvention. (Day, time and forum room to be announced.)

Phil Smith, W1EME, AMSAT Hamvention Coordinator, and his team have been working feverishly to make sure everything falls into place for Hamvention. There is still a need for volunteers to help staff the exhibit. With over 800 square feet of booth space and 20 hours of exhibit time, there is plenty of opportunity for members to spend a few hours to meet their fellow members and to help those new to the world of amateur satellites. Anyone willing to help for an hour or two should send Phil an email via w1eme [at] amsat [dot]org.

IARU Coordinates Two Amateur Radio Satellites

The IARU coordinated two upcoming satellites containing Amateur Radio payloads on April 4, 2022.

URESAT (HADES-B ITU designation) is a 1.5 P Pocketqube mission sponsored by AMSAT-EA. It will offer licensed radio amateurs around the world the opportunity to relay FM voice and AX.25/APRS 300/1200 bps communications. This will be achieved by implementing a SDR based FM and FSK repeater. A SSTV camera module by Brno University is expected to fly depending on time restrictions. Images would be taken randomly but the SSTV module would contain some ROM coded images to be transmitted as well. URESAT hardware and software subsystems are enhanced versions of the previous AMSAT-EA HADES satellite mission launched on a SpaceX Transporter-3 mission on January 3, 2022. A downlink on 436.888 MHz and an uplink on 145.975 MHz have been coordinated for a V/U FM voice repeater, a beacon with FSK, AFSK and APRS telemetry plus a CW beacon. The launch is planned for a 525km polar orbit with SpaceX in October 2022 managed by Exolaunch/Alba Orbital. More info at

LightCube is a 1U CubeSat educational mission sponsored by Arizona State University. Its aim is to inspire and provide a learning experience to people across the planet by producing a light visible to the naked eye. The flash, expected to be as bright as the International Space Station, will be produced by two Xenon flash tubes. The spacecraft will be triggered by Amateur Radio operators. This mission with its outreach goal of increasing the accessibility of satellites will inspire more people to become Amateur Radio licensees and to continue interacting with more CubeSats. In addition to triggering the LightCube flash, radio amateurs can also download and decode the telemetry information. A downlink on 437.175 MHz using 1k2 AFSK with AX25.has been coordinated. Planning a deployment from the ISS NET October 2022. More information at:

IARU-R1 Studies 23cm Band Amateur/RNSS Coexistence

CEPT SE40 meeting #76 being held April 11-13, 2022 is studying the issue of coexistence between Amateur Radio operation in 1240-1300 MHz and RNSS systems such as Galileo.

One of the agenda items for the World Radiocommunication Conference (WRC23) is AI-9.1b “Measures to be applied in the frequency band 1240-1300 MHz to ensure the protection of the radionavigation-satellite service (RNSS) in accordance with Resolution-774.”

SE40 is the CEPT ECC working group that looks at Space Service compatibility issues.

IARU Region 1 has submitted these documents to the April meeting:

  • Amateur density numbers
  • Amateur density numbers Background
  • Updated Proposals for WI_39 report

These papers and other meeting input documents can be downloaded from

Changes to AMSAT-NA TLE Distribution for April 14, 2022

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 satellite has decayed from orbit and has been removed from this week’s AMSAT-NA TLE distribution.

BOBCAT-1 NORAD Cat ID 51081 (decayed form orbit on 4/9/2022 per Space-Track).

Satellite Shorts From All Over

+ Replacing Satellite Components With SDRs
Traditional satellite RF communication systems can often have drawbacks. Software-defined radio can be used in satellite systems as a replacement for these traditional platforms, and have numerous benefits. SDRs can also be configured to various form factors for different payloads, for instance in cubesats. In addition to all these, SDRs are extremely rugged and radiation-resistant and area able to withstand the harsh conditions of space. Considering that satellites function in space for decades without any maintenance, this characteristic is particularly of benefit. Read the complete article at: [ANS thanks for the above information.]

+ Commercial Crew Adapting to Life on the ISS
One crewmember comments, “I think we underestimated just how hard the adaptation would be and sort of how long it would take,” Lopez-Alegra said. “You know, we have this phenomenon that astronauts call ‘space brain,’ when you get up here, things just take about 33 to 50 percent longer than they normally do. And that’s even more true for people who’ve never been exposed to this environment before.” Read the complete article at: [ANS thanks for the above information.]
