via the ARRL: Canadian Radio Amateur Finds Resurrected NASA Satellite

When he’s not on ham radio, Scott Tilley, VA7TIL, an amateur astronomer, hunts spy satellites. Using an S-band radio from his home in Roberts Creek, British Columbia, Tilley routinely scans the skies for radio signals from classified objects orbiting Earth, according to a recent article on Spaceweather.com. Since starting 5 years ago, Tilley has located dozens of secret […]

Why the US should notify the public of all satellite reentries

In January 2017, a retired satellite reentered the atmosphere—an old soldier that undoubtedly had provided many years of good service. Hopefully, in some secure vault somewhere, the organization that flew it had a ceremony where they honored the memory of their departed friend. This was certainly a US satellite that had been tracked and monitored […]

via the ARRL: January 1 Hosts Events for Legacy Keys, CW on Satellites

Every day is a good day to send CW, but January 1 is reserved for Straight Key Night (SKN), sponsored by ARRL. Enjoy CW as it has been sent and enjoyed since the earliest days of Amateur Radio. The 24-hour event, which gets under way at 0000 UTC on January 1 (New Year’s Eve in […]

via HACKADAY: Start Tracking Satellites with This Low-Cost Azimuth-Elevation Positioner

Tracking satellites and the ISS is pretty easy. All you really need is an SDR dongle or a handheld transceiver, a simple homebrew antenna, and a clear view of the sky. Point the antenna at the passing satellite and you’re ready to listen, or if you’re a licensed amateur, talk. But the tedious bit is […]

Zombie Satellites – Should We Fear the Graveyard Orbit of Un-dead Satellites?

If you’re prepared for ghosts, ghouls and goblins this Halloween, you might want to also consider zombies…satellites that is. Deep in outer space, where machines orbit the Earth, they share the sky with the un-dead. Can these historic satellites come back to life? HOW DO SATELLITES DIE? After a satellite completes its useful life and […]

via HACKADAY: Accidental Satellite Hijacks Can Rebroadcast Cell Towers

A lot of us will use satellite communications without thinking much about the satellite itself. It’s tempting to imagine that up there in orbit is a communications hub and distribution node of breathtaking complexity and ingenuity, but it might come as a surprise to some people that most communications satellites are simple transponders. They listen […]

via HACKADAY: Satellite Tracking With Friends

If you’re in the mood to track satellites, it’s a relatively simple task to look up one of a multitude of websites that can give you a list of satellites visible from your location. However, if you’re interested in using satellites to communicate with far-flung friends, you might be interested in this multi-point satellite tracker. […]

Oklahoma Radio Amateur is First to Score Satellite VUCC from Greenland

It took just 4 days — some of that time without much sleep — but ARRL member Gabe Zeifman, NJ7H/VE6NJH, of Oklahoma City recently became the first radio amateur to earn VUCC — working 100 grid squares — by satellite from Greenland. In fact, his is the first VUCC award of any kind from Greenland. […]

via HACKADAY: Old Rabbit Ears Optimized for Weather Satellite Downlink

Communicating with a satellite seems like something that should take a lot of equipment. A fancy antenna and racks full of receivers, filters, and amplifiers would seem to be the entry-level suite of gear. But listening to a weather satellite with an old pair of rabbit ears and an SDR dongle? That’s a thing too. […]

Virginia Engineering Students Tackle Satellite, Ground Station Projects

The University of Virginia (UVA) reports that some of its engineering students are among those at other Commonwealth schools working on Amateur Radio satellites and matching ground stations to track them and collect data. UVA said its student-built satellite is set to go into space late next year aboard an International Space Station resupply vehicle […]

via HACKADAY: See Satellites with a Simple Radio Telescope

Have you got a spare Dish Network antenna lying about? They’re not too hard to come by, either curbside on bulk waste day or perhaps even on Freecycle. If you can lay hands on one, you might want to try this fun radio telescope build. Now, don’t expect much from [Justin]’s minimalist build. After all, […]

Grote Reber Listens to Space: Out Of This World Hobbies at Eco Relics (Florida)

January is national hobby month, a time to acknowledge our interests that fall outside of our professions. Hobbyists and amateurs have reached the highest levels of human creativity, from backyard astronomers and garage chemists to Sunday painters and midnight scrawlers. Consider Grote Reber, for instance, an American original born in Wheaton, Illinois, in 1911. When […]

via HACKADAY: Junkyard Dish Mount Tracks Weather Satellites

There’s a magnificent constellation of spacecraft in orbit around Earth right now, many sending useful data back down to the surface in the clear, ready to be exploited. Trouble is, it often takes specialized equipment that can be a real budget buster. But with a well-stocked scrap bin, a few strategic eBay purchases, and a […]
