Collaborate Disseminate
There’s nothing quite like vintage hardware, and the way it looks and works is something that can be worth celebrating. [Old Tech. New Spec] did that with his loving modification …read more Continue reading Vintage Radio Gets Internet Upgrade
Astronomers have discovered strange radio signals that could be coming from unseen planets. Models suggest that some of the signals could be produced through interactions between the magnetic fields of planets and their host stars, which could represen… Continue reading Mysterious radio signals may be coming from undiscovered planets
With the push to having most of a radio receiver as part of a PC, it might seem odd to have a standalone communication receiver, but [OM0ET] reviews the latest …read more Continue reading Shortwave Radio Picks up Sideband
Astronomers have detected a strange radio source coming from somewhere near the center of the Milky Way galaxy. The signal repeats seemingly at random, and can’t be neatly attributed to any known astronomical object, leading the team to consider that i… Continue reading Bizarre repeating radio signal near galactic center may be brand new object
Astronomers have spotted a new type of supernova for the very first time. An unlucky star seems to have prematurely exploded after colliding with an extremely dense object, perhaps a black hole or a neutron star, creating a unique signature in the sky…. Continue reading New type of supernova detected as stellar corpse kills companion star
Lightning is a powerful and seemingly mysterious force of nature, capable of releasing huge amounts of energy over relatively short times and striking almost at random. Lightning obeys the laws …read more Continue reading Detect Lightning Strikes with an Arduino
We like regenerative receivers. They perform well and they are dead simple to create. Example? [Radio abUse] modified a few existing designs and built a one-transistor receiver. Well, one transistor …read more Continue reading Regen Receiver with Few Parts
Hopefully by now most of us know better than to rent a modem from an internet service provider. Buying your own and using it is almost always an easy way …read more Continue reading Cable Modem Turned Spectrum Analyzer
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
