Fox Hunting with Software-Defined Radio

Fox hunting, or direction finding, is a favorite pastime in the ham radio community where radio operators attempt to triangulate the position of a radio transmission. While it may have required a large amount of expensive equipment in the past, like most ham radio operations the advent of software-defined radio …read more

Indoor Antennas Worthy of 007

Many ham radio operators now live where installing an outdoor antenna is all but impossible. It seems that homeowner’s associations are on the lookout for the non-conformity of the dreaded ham radio antenna. [Peter] can sympathize, and has a solution based on lessons of spycraft from the cold war.

[Peter] …read more

FM Radio from Scratch using an Arduino

Building radio receivers from scratch is still a popular project since it can be done largely with off-the-shelf discrete components and a wire long enough for the bands that the radio will receive. That’s good enough for AM radio, anyway, but you’ll need to try this DIY FM receiver if …read more

“Odd radio circles” are the latest cosmic mystery to stump astronomers

With the mystery of fast radio bursts looking increasingly solved, astronomers need a new cosmic conundrum to ponder. And right on cue, a brand new noodle-scratcher has emerged from the depths of space – everyone, meet “odd radio circles,” or ORCs.Cont… Continue reading “Odd radio circles” are the latest cosmic mystery to stump astronomers

iPhone Bug Allowed for Complete Device Takeover Over the Air

Researcher Ian Beer from Google Project Zero took six months to figure out the radio-proximity exploit of a memory corruption bug that was patched in May. Continue reading iPhone Bug Allowed for Complete Device Takeover Over the Air

Gathering Eclipse Data Via Ham Radio

A solar eclipse is coming up in just a few weeks, and although with its path of totality near the southern tip of South America means that not many people will be able to see it first-hand, there is an opportunity to get involved with it even at an extreme …read more

Earth is 2,000 light-years closer to galactic center than we thought

For two decades the Japanese VERA radio astronomy project has been gathering data to build up a 3D map of the position and velocity of objects revolving in our galaxy. The latest analysis indicates that the Earth is 2,000 light-years closer to the cent… Continue reading Earth is 2,000 light-years closer to galactic center than we thought

HackRF PortaPack Firmware Spoofs All the Things

The HackRF is an exceptionally capable software defined radio (SDR) transceiver, but naturally you need to connect it to a computer to actually do anything with it. So the PortaPack was developed to turn it into a stand-alone device with the addition of a touchscreen LCD, a few buttons, and …read more
