The Amateur Radio on the International Space Station (ARISS) “Ham Video” digital Amateur Radio TV (DATV) transmitter on the International Space Station (ISS) is reported to be defective, with onboard repair not possible. Also known as HamTV, the DATV system stopped working in mid-April, and a subsequent test on June 1 using a second L/S […]

via the ARRL: Unicorn-2A PocketQube to Launch Later this Year from Alaska

According to a BBC News report, a new UK-built PocketQube satellite, Unicorn-2A, developed by radio amateurs at Glasgow’s Alba Orbital, will launch later this year from Alaska. Three radio amateurs at Alba Orbital worked on Unicorn-2A, which will have downlinks in the 437 MHz and 2400 MHz bands. One of the transmission modes will be LoRa, a patented wireless communication […]

via the ARRL: Radio Amateurs to Swap Spots on International Space Station (ISS) Crew

One radio amateur now onboard the International Space Station will be heading home on June 3, while two more will come aboard a few days later. Flight Engineer Scott Tingle, KG5NZA, will join Expedition 55 Commander Anton Shkaplerov and Flight Engineer Norishige Kanai in returning to Earth on the Soyuz MS-07 spacecraft after 168 days […]

via the ARRL: Post-Launch Signals Received as Amateur Radio Heads to Moon

China has launched two microsatellites into a lunar transfer orbit. They launched as secondary payloads with the Quequiao relay satellite on May 20, in conjunction with the Chang’e 4 mission to the far side of the moon. Once in lunar orbit, DSLWP-A1 and DSLWP-A2 (DSLWP = Discovering the Sky at Longest Wavelengths Pathfinder) — also known as Longjiang-1 and Longjiang-2 — […]

via the ARRL: FCC Releases Notice of Proposed Rulemaking on Small Satellites

The FCC released a Notice of Proposed Rulemaking (NPRM) on April 17, seeking comment on proposals to streamline its rules regarding the deployment of “small satellites.” This would include small spacecraft put into orbit for Amateur Radio purposes, as well as small satellites launched by non-Amateur Radio entities, such as universities, but using Amateur Radio spectrum. The NPRM primarily addresses […]

via the ARRL: More Frequent Spotless Days Now, Can Signal Solar Activity in the Future, Top Contester Says

The sunspot numbers have not been good, and it does not seem they’ll be getting much better anytime soon. According to the April 6 “K7RA Solar Update,” only 2 days of the March 29 – April 4 reporting week saw sunspots, and that was at the bare minimum. No sunspots showed at all for the […]
