via the ARRL: Caution Urged in Using High Duty Cycle Digital Modes on Satellites

Satellite enthusiasts planning to try FT8 or MSK144 via satellite are being urged to use caution or possibly to avoid digital modes altogether in light of problems being blamed on the modes’ high duty cycle. Stations have reported problems getting into satellite transponders, even during favorable passes, which were traced to digital-mode signals in the […]

The next AMSAT Fox-1 satellite, RadFxSat (Fox-1B), is scheduled to launch on November 10 at 0947 UTC. RadFxSat (Fox-1B), which will carry a 435/145 MHz FM transponder, is one of four CubeSats making up the NASA ELaNa XIV mission, riding as secondary payloads aboard the Joint Polar Satellite System-1 (JPSS-1) mission. JPSS-1 will launch on […]

via the ARRL: Chinese CAS-4A and CAS-4B Amateur Radio Satellite Transponders Activated

The Amateur Radio linear (SSB/CW) inverting transponders on the CAS-4A and CAS-4B satellites were activated on October 18. CAMSAT’s Amateur Radio payloads piggybacked on the optical remote-sensing micro-satellites OVS-1A (CAS-4A) and OVS-1B (CAS-4B), launched on June 15. CAS-4A (call sign BJ1SK) has a CW telemetry beacon on 145.855 MHz, and 4.8 kB GMSK telemetry on […]

SpaceX seeks FCC approval to test satellite communications system in Seattle area

SpaceX has filed an application with the Federal Communications Commission to begin ground testing of a satellite communications system between its facilities in Redmond, Wash., as early as this month. Redmond is the base of operations for SpaceX’s multibillion-dollar effort to create a 4,425-satellite constellation in low Earth orbit for global broadband internet access and […]

Minisatellite surge spurs downlink infrastructure

Joshua Semeter needed a data plan. Not for his smartphone, but for his satellite. Semeter, an engineering professor at Boston University, is the principal investigator for ANDESITE, a toaster-sized satellite destined for low-Earth orbit. After it launches in November, the satellite will eject a cloud of eight even smaller sensors that will track how the […]

VIDEO: Spacewalk 360: RT releases first-ever panoramic video of man in outer space (with Amateur Radio CubeSat Launches)

The video, which shows out-of-this-world views of Planet Earth, is the first time that the so-called extravehicular activity (EVA) has been filmed in 360. The immersive new format previously helped viewers explore the ISS modules as part of the Space 360 project. Cosmonauts Sergey Ryazansky and Fedor Yurchikhin captured the breathtaking scenery while doing their […]

via the ARRL: Ham-Astronauts Taking Part in Spacewalks this Month

Two ham-astronauts on the International Space Station (ISS) crew will participate in a trio of spacewalks this month. NASA Television and the agency’s website will provide live coverage of the spacewalks. Expedition 53 Commander Randy Bresnik will lead all three spacewalks. He’ll be joined on October 5 and 10 by Flight Engineer Mark Vande Hei, KG5GNP, while […]

via the ARRL: FalconSAT-3 Now Open for Amateur Radio Use

The Air Force Academy satellite FalconSAT-3 is now open for Amateur Radio use as a digital store-and-forward system. Built in 2005 and 2006 by cadets and faculty in the Space Systems Research Center at the US Air Force Academy in Colorado Springs, FalconSAT-3 was launched in 2007. The satellite has completed its scientific and training […]

via the ARRL: HamSCI Presents Initial Eclipse Results at ARRL-TAPR Digital Communications Conference

At the 36th annual ARRL and TAPR Digital Communications Conference (DCC), held September 15–17 this year in St. Louis, HamSCI members presented preliminary evidence that the August 21 solar eclipse had a significant effect on HF propagation. The DCC is geared toward technically minded Amateur Radio operators who specialize in building and designing hardware and […]

via the ARRL: ARISS Invites Proposals to Host Amateur Radio Contacts with Space Station Crew

The Amateur Radio on the International Space Station (ARISS) program is seeking proposals from US schools, museums, science centers, and community youth organizations to host Amateur Radio contacts in 2018 with a crew member aboard the International Space Station (ISS). The deadline to submit proposals is November 15. Contacts would be scheduled between July 1 […]

Two Radio Amateurs are Among Three New ISS Crew Members

After a 6-hour flight, astronauts Mark Vande Hei, KG5GNP, and Joe Acaba, KE5DAR, and cosmonaut Alexander Misurkin arrived at the International Space Station on September 12. The trio launched aboard the Soyuz MS-06 spacecraft from Kazakhstan, orbited Earth four times, and then docked at the space station. The hatches between the spacecraft and station opened […]

via the ARRL: Space Weather Prediction Center Says Solar Phenomena May Continue

The Space Weather Prediction Center (SWPC) said today that G4 (Severe) geomagnetic storm levels were observed at 2350 UTC on September 7 and again at 0151 UTC and 1304 UTC on September 8, due to the effects of a coronal mass ejection (CME). A G3 (Strong) or greater warning was in effect until 1500 UTC […]
