via the ARRL: Major Rove by Satellite Ops Could Make Rare Grids Squares Available

2018 ARRL International Grid Chase (IGC) participants take note: satellite operators Doug Tabor, N6UA, and Ken Alexander, VE3HLS, will travel to the James Bay area of Québec, Canada, in early May, activating as many FO grid squares as are accessible by road in the limited time they have. The plan is to arrive in FO […]

via HACKADAY: Fail of the Week: How Not To Build Your Own DGPS Base Station

GPS is the modern answer to the ancient question about one’s place in the world yet it has its limitations. It depends on the time of flight of radio signals emitted by satellites twenty thousand kilometers above you. Like any system involving large distances and high velocities, this is bound to offer some challenges to […]

via HACKADAY: At 71,572 KM, You Won’t Beat This LoRa Record

A distance record for LoRa transmission has been set that you probably won’t be able to beat. Pack up your gear and go home, nothing more to achieve here. At a superficial reading having a figure of 71,572 km (44,473 miles) seems an impossible figure for one of the little LoRa radio modules many of […]

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. […]
