via HACKADAY: Es’hail-2: Hams Get Their First Geosynchronous Repeater

In the radio business, getting the high ground is key to covering as much territory from as few installations as possible. Anything that has a high profile, from a big municipal water tank to a roadside billboard to a remote hilltop, will likely be bristling with antennas, and different services compete for the best spots […]

via the ARRL: German Radio Amateur Successfully Sends 2.5 mW OPERA Signal via Es’hail-2

Markus Vester, DF6NM, recently used the digital mode OPERA to send a 2.5 mW signal through the 2.4 – 10 GHz transponder of the Es’hail-2 (QO-100) geostationary satellite. OPERA is a “slow” digital mode for very weak signal work that enables the exchange of call signs and signal reports. According to a post on the Digital Radio […]

via the ARRL: KickSat-2 is Alive and Being Tracked

For the first couple of days after the 3U KickSat-2 was deployed from Cygnus NG-10 last November, nothing was heard from the satellite. But in a February 16 post to AMSAT-BB, Nico Janssen, PA0DLO, reported receiving several short and weak transmissions from KickSat 2 — short telemetry bursts on 437.5077 MHz. Assistant Professor of Aeronautics and Astronautics at […]

via the RSGB: Geostationary satellite transponder active

The geostationary amateur radio narrowband transponder on the Es’hail-2/QO-100 was made available for amateur experimental use on the afternoon of Tuesday, 12 February 2019. The 250kHz bandwidth transponder uses the 2.4GHz band for the uplink with the downlink in the 10.45GHz band and should provide communications over a wide portion of the globe. Potentially both Brazil […]

via the ARRL: AO-85 Turned Off due to Return of Eclipse Periods and Poor Battery Condition

The Fox-1A (AO-85) CubeSat has been turned off until further notice due to return of eclipses and poor battery condition, control operator Mark Hammond, N8MH, has announced. In December, AO-85 experienced precarious battery voltage drops during eclipse periods; it’s believed that the batteries suffered degradation due to heat during previous no-eclipse periods, making it difficult […]

via the ARRL: ARISS Plans Do-Over of Slow-Scan TV Transmissions over February 15 – 17 Weekend

Amateur Radio on the International Space Station (ARISS) is planning another popular slow-scan television (SSTV) event in the wake of an SSTV experiment last weekend, during which signals were reported to have been weak. Even so, more than 5,500 images were submitted. Transmissions are scheduled to begin on Friday, February 15, at 0845 UTC and […]

via the ARRL: ISS Packet Radio System is Back in Operation with New Equipment

The Amateur Radio on the International Space Station (ARISS) packet system is back on the air with new equipment. The replacement gear arrived last November and had been awaiting unpacking and installation. ARISS hardware team members on the ground were able to locate a functional duplicate of the old ISS packet TNC module that had […]

via the ARRL: MarconISSta Offering One Last Chance to Test UHF Antennas

The MarconISSta experiment at the Amateur Radio on the International Space Station (ARISS) Columbus module ham station will be decommissioned on February 9, about 3 weeks earlier than anticipated. MarconISSta is a radio spectrum analyzer on the ISS that monitors parts of the RF spectrum in VHF, UHF, L, and S bands in order to analyze current use and […]

via the ARRL: AMSAT Announces 50th Anniversary Space Symposium

The 2019 AMSAT 50th Anniversary Symposium will take place on October 18 – 20 at the Hilton Arlington in Arlington, Virginia, next to Washington, DC. Connected to the Ballston Metro Station, the hotel offers easy access to the capital’s top tourist destinations, and tours will be available; it’s 6 miles from Reagan National Airport. The […]

via the ARRL: Es’hail-2/P4A Satellite is Designated as Qatar-OSCAR 100 (QO-100)

AMSAT has now granted OSCAR status to 100 Amateur Radio satellites. The latest, Es’hail-2/P4A — now Qatar-OSCAR 100 (QO-100) —launched from Cape Canaveral, Florida, in November. It carries the first geosynchronous Amateur Radio payload. Es’hail-2/P4A was developed jointly by the Qatar Amateur Radio Society (QARS) and Es’hailSat (the Qatar Satellite Company), with AMSAT-DL as the […]

via the ARRL: Earth’s Magnetic North Pole Shifts toward Siberia

National Centers for Environmental Information (NCEI) scientists have updated the world magnetic model (WMM) mid-cycle, as Earth’s northern magnetic pole has begun shifting quickly away from the Canadian Arctic and toward Siberia, an NCEI report said this week. The new WMM more accurately represents the change of the magnetic field since 2015. The alteration could have an […]

via the ARRL: ARISS Announces Slow-Scan Television Event

Amateur Radio on the International Space Station (ARISS) has announced another slow-scan television (SSTV) transmission event, using images from the NASA on the Air (NOTA) program that celebrated NASA’s 60th anniversary and key events in NASA’s early history during 2018. Transmissions are scheduled to start on Friday, February 8, at 1400 UTC and run through […]

via HACKADAY: The 1859 Carrington Event

Like many Victorian gentlemen of means, Richard Carrington did not need to sully himself with labor; instead, he turned his energies to the study of natural philosophy. It was the field of astronomy to which Carrington would apply himself, but unlike other gentlemen of similar inclination, he began his studies not as the sun set, […]

via the RSGB: Slow-scan TV experiment on ISS

The Inter-MAI amateur radio slow scan television experiment on the International Space Station is scheduled to be activated between Wednesday, 30 January and Friday, 1 February. It appears that the experiment will only be active during a couple of orbits that overfly Moscow, rather than a continuous operation. Expected periods of activation appear to be […]
