As mysterious as fast radio bursts (FRBs) are, they’re now so common that they’re at risk of becoming mundane. But a newly discovered signal deepens the mystery with a few oddities – it hails from an unexpected region of space, and its pulses are about… Continue reading Ultra-fast radio burst could usher in whole new class of space signals
We’ve said it before and we’ll say it again: the best part about holding an amateur radio license is that it lets you build and use your own transmitting equipment. …read more Continue reading Retro and New Tech Combine in this Hybrid Ham Transmitter
Millimeter-wave Radars used in modern cars for cruise control and collision avoidance are usually designed to work at ranges on the order of 100 meters or so. With some engineering …read more Continue reading Machining Waveguides For 122 GHz Operation Is Delicate Work
Astronomers have discovered a bizarre radio signal coming from somewhere in our galaxy that can’t be explained by any known object. When it’s active the source gives off energetic radio bursts lasting up to a minute, every 20 minutes – which should be … Continue reading Bizarre radio signal repeating every 18 minutes discovered in Milky Way
If you read old antenna books, you’ll probably see the idea of phased vertical antennas. These use certain lengths of coax to control the phase of a signal going to …read more Continue reading Directional Antenna 3-Way
As consumer electronics companies chase profits on tighter and tighter margins, it seems like quality is continually harder to find for most average consumer-grade products. Luckily, we don’t have to …read more Continue reading Modern Features In Classic Radio
For radio enthusiasts worldwide, the inexpensive Chinese handheld radios produced by the likes of Baofeng and other brands have been a welcome addition to their arsenal. They make an ideal …read more Continue reading Is The Game Up For Baofeng In Europe?
Mission extensions for interplanetary robot explorers are usually continuations of their primary mission. But sometimes the hardware already on board are put to novel uses. European Space Agency has started …read more Continue reading Two Mars Orbiters Chatted for Atmospheric Science
The Starlink beta has semi-officially ended, but it seems as though the global chip shortage is still limiting how many satellites are flying around the world for broadband internet access …read more Continue reading Detect Starlink Satellites Passing By
Astronomers have spotted two “invisible” galaxies hiding near the dawn of the universe. The team used radio waves to peer behind a curtain of dust that was obscuring them from view, and the find suggests that there were far more galaxies in the early u… Continue reading Astronomers spot “invisible” galaxies at the dawn of the universe
