via HACKADAY: Bidirectional IP with New Packet Radio

There are a few options if you want to network computers on amateur radio. There are WiFi hacks of sort, and of course there’s always packet radio. New Packet Radio, a project from [f4hdk] that’s now on hackaday.io, is unlike anything we’ve seen before. It’s a modem that’s ready to go, uses standard 433 ISM band […]

via HACKADAY: Eavesdropping On Cosmonauts With An SDR

Usually when we hear about someone making contact with astronauts in orbit, it’s an intentional contact between a ham on the ground and one of the licensed radio amateurs on the ISS. We don’t often see someone lucky enough to snag a conversation between ground controllers and a spacecraft en route to the ISS like this. For […]

via HACKADAY: WOPR: Security Loses Some of its Obscurity

As we’ve seen time and time again, the word “hacker” takes on a different meaning depending on who you’re talking to. If you ask the type of person who reads this fine digital publication, they’ll probably tell you that a hacker is somebody who likes to learn how things work and who has a penchant […]

via HACKADAY: EBay Modules And Custom PCBs Make A Plug And Play Ham Transceiver

Many of us have fond memories of our introduction to electronics through the “200-in-1” sets that Radio Shack once sold, or even the more recent “Snap Circuits”-style kits. Most of eventually us move beyond these kits to design our circuits; still, there’s something to be said for modular designs. This complete amateur radio transceiver is a great […]

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 HACKADAY: World’s Oldest Computer Festival is This Weekend

There was a time when owning a home computer was kind of a big deal. In the days before the popularization of the Internet, so-called “computer shows” were the best way to meet with others to swap advice, information, and hardware. Of course today, things are very different. The kind of people who are building […]

via HACKADAY: The $50 Ham: Entry-Level Transceivers for Technicians

Last week , I covered the ridiculously low barriers to entry to amateur radio, both in terms of financial outlay and the process of studying for and passing the FCC examination. You’ve had seven days, so I assume that you’ve taken the plunge and are a freshly minted amateur radio operator. The next big question may […]

via HACKADAY: Justin McAllister’s Simple, Post-Apocalypse-Friendly Antennas

Watch Justin McAllister’s presentation on simple antennas suitable for a zombie apocalypse and two things will happen: you’ll be reminded that everything antennas do is amazing, and their reputation for being a black magic art will fade dramatically. Justin really knows his stuff; there is no dangle-a-wire-and-hope-for-the-best in his examples. He demonstrates that it’s possible to communicate […]
