Collaborate Disseminate
Fast radio bursts (FRBs) are among the most intriguing cosmic mysteries of our time, and now we might be one step closer to an answer for what creates them. By examining multiple “radio colors” simultaneously in a batch of repeating signals, astronomer… Continue reading Multicolored radio rules out more suspects in fast radio burst mystery
We will have all at some point seen a fascinating project online, only to find not enough information to really appreciate and understand it. Such a project came [Bill Meara]’s …read more Continue reading Traditional Analogue And An FPGA Make This Junkbox HF Receiver A Bit Special
We’ll admit we haven’t heard of the AGS-38, it reminds us of the shortwave receivers of our youth, and it looks like many that were made “white label” by more …read more Continue reading Rare Radio Receiver Teardown
Astronomers have taken a close-up image of a radio jet emitted by a supermassive black hole for the first time. The Event Horizon Telescope (EHT) has zoomed in on this jet with 16 times the resolution and at 10 times higher frequencies than previous ob… Continue reading Event Horizon Telescope snaps close-up of supermassive black hole jets
Dipoles are a classic builder’s antenna, after all they are usually little more than two pieces of wire and a feedline. But as [Rob] shows us in the video below, …read more Continue reading A Cheap Dipole Antenna from an Extension Cord
We don’t normally embrace the supernatural here at Hackaday, but when the topic turns to the radio frequency world, Arthur C. Clarke’s maxim about sufficiently advanced technology being akin to …read more Continue reading New Video Series: Learning Antenna Basics with Karen Rucker
Last year, as my Corona Hobby™, I took up RC plane flying. I started out with discus-launched gliders, and honestly that’s still my main love, but there’s only so much …read more Continue reading You Can’t Fix What You Can’t Measure
What do you do with floral wire and balloons from Dollar Tree? If you are [Ham Radio Crash Course], you make a ham radio antenna. Floral wire is conductive, and …read more Continue reading Balloon Antenna Doesn’t Need a Tower
Japanese astronomers have discovered the echoes of a “dying” supermassive black hole. While the object is quiet now, the team spotted the signatures of two huge radio jets that indicate it only recently fell silent after a bright, active phase.Continue… Continue reading Astronomers discover dying echoes of a supermassive black hole
It’s easy to get caught up in a build and forget that the final version usually needs some sort of enclosure, especially things with sensitive electronics in them. The [Director …read more Continue reading Radio Build Goes Outside The Box
