Fast radio bursts (FRBs) are one of the most intriguing mysteries of modern astronomy. Picked up from all corners of the cosmos, these perplexing radio signals usually only last milliseconds before fading forever, but some particularly strang… Continue reading Eight new repeating radio signals detected from deep space
The meaning of the word portable has changed a bit over the years. These days something has to be pretty tiny to be considered truly portable, but in the 1940s, anything with a handle on it that you could lift with one hand might be counted as portable electronics. Zenith …read more
In about five billion years’ time, the Sun will grow into a red giant, probably swallowing the Earth and putting an end to any and all life that’s still kicking then. As this material is shed off, the Sun itself will become a small, dim, whit… Continue reading Astronomers hope to search for radio waves broadcast from dead planets orbiting dead stars
Statistically, it’s pretty much a given that alien life is out there somewhere, whether that’s Martian microbes or highly intelligent life beaming comms through the cosmos. While the Curiosity rover is poking around in the dirt for the former… Continue reading Powerful new telescope joins the search for possible laser pulses from aliens
Coherers were devices used in some of the very earliest radio experiments in the 19th century. Consisting of a tube filled with metal filings with an electrode at each end, the coherer would begin to conduct when in the presence of radio frequency energy. Physically tapping the device would then …read more
Would you add another radio to your smartphone? No, not another WiFi or cellular radio; a smartphone already has that. I’m talking about something that provides connectivity through ISM bands, either 433 or 915 MHz. This can be used where you don’t have cell phone coverage, and it has a …read more

Strange signals known as fast radio bursts (FRBs) are one of the most intriguing mysteries of modern astronomy, so the more of them we can locate, the closer we get to figuring what causes them. Now we’re a step closer to solving the riddle, … Continue reading Astronomers close in on the fast radio burst mystery by tracing new signal to distant galaxy
Antique radio receivers retain a significant charm, and though they do not carry huge value today they were often extremely high quality items that would have represented a significant investment for their original owners. [CodeMakesItGo] acquired just such a radio, a Philco 37-11 made in 1937, and since it was …read more
