via HACKADAY: Drone + Ground Penetrating Radar = Mine Detector?

Most civilized nations ban the use of landmines because they kill indiscriminately, and for years after they are planted. However, they are still used in many places around the world, and people are still left trying to find better ways to find and remove them. This group is looking at an interesting new approach: using ground-penetrating […]

via the ARRL: DX Group Seeks Reconsideration of Kure Atoll DXpedition Permit Application

The Pacific Islands DXpedition Group (PIDXG) is hoping to gain approval of its latest application for a DXpedition from Kure Atoll — currently the 7th most-wanted DXCC entity according to Club Log. The last ham radio activity on Kure Atoll took place in 2005. Once home to a US Coast Guard LORAN station, Kure Atoll […]

via HACKADAY: An Enigma Wrapped In A Riddle Wrapped In A Vintage Radio

Puzzle boxes are great opportunities for hacking. You can start with a box which was originally used for something else. You get to design circuitry and controls which offer a complex puzzle for the players. And you can come up with a spectacular reward for those who solve it. [thomas.meston’s] Dr. Hallard’s Dream Transmission Box, which […]

“Hello, America. This is the International Space Station. Who’s out there?” And with that “CQ” of sorts on 145.800 MHz, NASA astronaut Serena Auñón-Chancellor, KG5TMT, MD, spent some time at the helm of NA1SS on October 6 making casual, random contacts — something that’s fairly rare these days. The ISS was on a pass that […]

via HACKADAY: Studying Airplane Radio Reflections With SDR

A property of radio waves is that they tend to reflect off things. Metal surfaces in particular act as good reflectors, and by studying how these reflections work, it’s possible to achieve all manner of interesting feats. [destevez] decided to have some fun with reflections from local air traffic, and was kind enough to share the […]

via HACKADAY: Fully 3D Printed And Metalized Horn Antennas Are Shiny and Chrome

We’ve seen our share of 3D printed antennas before, but none as well documented and professionally tested as [Glenn]’s 3D printed and metalized horn antennas. It certainly helps that [Glenn] is the principal engineer at an antenna testing company, with access to an RF anechoic chamber and other test equipment. Horn antennas are a fairly simple […]

via HACKADAY: Buy A Baofeng While You Still Can? FCC Scowls at Unauthorized Frequency Transmitters

There was a time when a handheld radio transceiver was an object of wonder, and a significant item for any radio amateur to own. A few hundred dollars secured you an FM walkie-talkie through which you could chat on your local repeater, and mobile radio was a big draw for new hams. Thirty years later […]

via HACKADAY: Tiny Telescope For Simple Radio Astronomy

We are used to imagining radio telescopes as immense pieces of scientific apparatus, such as the Arecibo Observatory in Puerto Rico, or the Lovell telescope in the UK. It’s a surprise then that they can be constructed on a far more modest sale using off-the-shelf components, and it’s a path that [Gonçalo Nespral] has taken […]

via the ARRL: AMSAT-DL Symposium Hears Update on Es’hail-2 Geostationary Satellite

Progress toward the launch of the Es’Hail-2 geostationary Amateur Radio satellite was reported as AMSAT-DL held its annual symposium on September 29 at the Institute for Environment and Future Research (IUZ) Bochum Observatory in Germany. Es’hail-2 is set to go into space this fall or early winter aboard a SpaceX vehicle; a specific launch date is not available. AMSAT-DL […]

via the ARRL: IARU Region 1 Volunteers and Partners Getting Behind WRC-19 50 MHz Agenda Item

International Amateur Radio Union (IARU) volunteers are continuing their work toward a favorable outcome for World Radio Conference 2019 (WRC-19) Agenda Item 1.1, which seeks a 6-meter allocation for the Amateur Radio Service in Region 1 in the International Telecommunication Union (ITU) Radio Regulations Table of Frequency Allocations. The effort is aimed at aligning the band with […]

via the ARRL: ARRL, FCC Discussing Issue of Uncertified Imported VHF/UHF Transceivers

ARRL has taken a minor exception to the wording of a September 24 FCC Enforcement Advisory pertaining to the importation, marketing and sale of VHF and UHF transceivers and is in discussion with FCC personnel to resolve the matter. The Enforcement Advisory was in response to the importation into the US of certain radio products that are not FCC […]

via the ARRL: Online Fundraising Campaign Backs ISS Radio Upgrades

ARISS and AMSAT are supporting a FundRazr campaign to raise $150,000 for critical ham radio infrastructure upgrades on the International Space Station (ISS). “ARISS is in critical need of infrastructure upgrades to ensure that programs such as talking to astronauts in space using Amateur Radio can continue,” ARISS International President Frank Bauer, KA3HDO, said. ARISS seeks several upgrades, including new […]

via the ARRL: Scouting’s Jamboree on the Air (JOTA) Looking Forward to Successful 2018 Event

Some 450 sites in the US are among nearly 3,000 locations around the world that will host Jamboree on the Air (JOTA) or Jamboree on the Internet (JOTI) stations over the October 19 – 21 weekend. “It looks [like it will] exceed last year’s registration number by next weekend,” JOTA Coordinator Jim Wilson, K5ND, said.
