via HACKADAY: AI Finds More Space Chatter

Scientists don’t know exactly what fast radio bursts (FRBs) are. What they do know is that they come from a long way away. In fact, one that occurs regularly comes from a galaxy 3 billion light years away. They could form from neutron stars or they could be extraterrestrials phoning home. The other thing is […]

via the ARRL: Radio Amateurs Receive Images from Chinese Lunar Satellite

Some earthbound radio amateurs and sky watchers have received images from a tiny Chinese satellite now orbiting the moon. In May, China launched the DSLWP-A and DSLWP-B microsatellites — also known as Longjiang-1 and Longjiang-2 — into a lunar transfer orbit, although Longjiang-1 was apparently lost in the process and likely remains in deep Earth orbit. They were deployed as secondary […]

via the ARRL: Reverse-Polarity Sunspot Group Does Not Belong to Cycle 25, Observatory Says

The Royal Observatory of Belgium’s Solar-Terrestrial Centre of Excellence (STCE) has asserted that the reverse polarity sunspot group 2720 observed in late August belongs to the current solar cycle — Cycle 24 — and does not represent the start of Cycle 25. “Because of its reversed polarity, some websites claimed sunspot group 2720 was possibly one of […]

via the ARRL: Digital Mobile Radio Hotspots May Be Interfering with Satellite Uplinks, AMSAT Reports

This week, AMSAT News Service (ANS) cited an August 27 report from AMSAT Vice President-Operations Drew Glasbrenner, KO4MA, saying that a digital mobile radio (DMR) signal has been interfering with the AO-92 (Fox-1D) satellite’s 435.35 MHz uplink frequency. Glasbrenner said hotspots, repeaters, terrestrial simplex, and “anything not satellite” should never transmit in the segments 145.8 […]

via the ARRL: Chinese Amateur Radio Satellites Receive OSCAR Designations

AMSAT has announced that it has granted OSCAR designators for the Chinese DSLWP-A and DSLWP-B microsatellites, successfully launched on May 18 into a lunar transfer orbit by a CZ-4C launch vehicle. DSLWP-A is Lunar-OSCAR 93 (LO-93), and DSLWP-B is Lunar- OSCAR 94 (LO-94). Telemetry signals were received from both satellites soon after launch, although DSLWP-A was […]

Es’hailSat, the Qatar Satellite Company, has tweeted that it’s anticipating that SpaceX will launch its geostationary Es’hail-2 satellite sometime in the 4th quarter of 2018. The commercial Qatari satellite will provide the first Amateur Radio geostationary communication and will be capable of linking amateurs from Brazil to Thailand. Es’hail-2 will carry two AMSAT-DL-designed Phase 4 Amateur Radio […]

via the ARRL: Indonesian Hams Take Advantage of Satellite for Post-Earthquake Communication

Amateur Radio volunteers in Indonesia have been taking advantage of the LAPAN-ORARI (IO-86) ham satellite in addition to HF on 7.110 MHz as the Lombok area recovers from two recent earthquakes. The death toll now has topped 400. A second powerful earthquake in the area on August 5 killed at least 98 people and seriously […]

via the ARRL: Slow-Scan TV Transmissions from International Space Station Set for July 30 – 31

Russian cosmonauts on the International Space Station are expected to activate Amateur Radio Slow Scan Television (SSTV) transmissions on 145.800 MHz FM on July 30 and 31 The SSTV experiment should be active on Monday, July 30, 1600 – 1930 UTC, and Tuesday, July 31, 1325 – 1915 UTC, using the RS0ISS call sign. SSTV […]

via the ARRL: BIRDS-2 Constellation CubeSats Transported to ISS for August Deployment

The second generation of CubeSats in the BIRDS constellation now is on board the International Space Station (ISS) and set for deployment in early August using the Japan Aerospace Exploration Agency (JAXA) module’s remote manipulator arm. The June 29 SpaceX Falcon 9 launch carried the BIRDS-2 CubeSats — MAYA-1, BHUTAN-1, and UiTMSAT-1, built by students from Malaysia, […]

via the ARRL: CASSIOPE Spacecraft Listens In on 2018 ARRL Field Day

The Canadian CASSIOPE (CAScade, Smallsat, and Ionospheric Polar Explorer) spacecraft once again eavesdropped on ARRL Field Day activity. CASSIOPE’s Radio Receiver Instrument (RRI) was tuned to 7.005 MHz during six passes over the North American continent during Field Day 2018, although there was no advance publicity this year. The RRI is a component of the spacecraft’s Enhanced […]

via the ARRL: CubeSats to Deploy from International Space Station on July 13

Japan’s space agency JAXA has announced that nine CubeSats will be deployed from the International Space Station on July 13. Three of the satellites — EnduroSat AD, EQUISat, and MemSat — will transmit telemetry in the 70-centimeter Amateur Radio band. EnduroSat AD will transmit on 437.050 MHz (CW, 9.6 kB GFSK); EQUISat will transmit on […]

via the ARRL: CAMSAT Offers More Details on New Satellites, One Carrying HF Transponders

CAMSAT, China’s Amateur Radio Satellite organization, has offered additional details about the three Amateur Radio satellites it plans to launch later this year. Two of the satellites, designated CAS-5A and CAS-6, will carry transponders, and one of them will offer HF capability. CAMSAT’s Alan Kung, BA1DU, told ARRL that the 6U CAS-5A will carry two […]

via the ARRL: Space Station Digital Amateur Radio TV System Transmitter Determined to be Defective

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 […]
