Collaborate Disseminate
Astronomers are another step closer to solving one of the most intriguing cosmic mysteries of recent times – fast radio bursts (FRBs). A team has now traced five signals to their points of origin within the spiral arms of galaxies, narrowing down the l… Continue reading Five fast radio bursts tracked to home galaxies
Swim coaches have a difficult job, as they have to shout in order for swimmers to hear them – and even then, they still may not be heard. The Sonr system is designed to address that problem, using one-way radio communications.Continue ReadingCategory: … Continue reading Sonr tech lets coaches talk to swimmers by radio
There’s no doubt that the RTL-SDR project has made radio hacking more accessible than ever, but there’s only so far you can go with a repurposed TV tuner. Obviously the …read more Continue reading The Evil Crow is Ready To Cause Some RF Mayhem
In a world with software-defined radios and single-chip receivers, a superheterodyne shortwave radio might not exactly score high on the pizzazz scale. After all, people have been mixing, filtering, and …read more Continue reading A Superheterodyne Receiver with a 74xx Twist
The mystery of fast radio bursts (FRBs) from space may be a step closer to being solved. Astronomers studying a repeating signal from a nearby galaxy have detected radiation at the lowest frequency of any FRB found so far, providing new potential hints… Continue reading Astronomers detect new frequencies from mysterious fast radio bursts
Apparently, if the GPS on your shiny new DJI FPV Drone detects that it’s not in the United States, it will turn down its transmitter power so as not to …read more Continue reading Web Tool Cranks Up The Power on DJI’s FPV Drone
If you are a ham radio operator, the idea of sending pictures and data over voice channels is nothing new. Hams have lots of techniques for doing that and — …read more Continue reading Web Pages (and More) via Shortwave
Artificially constrained designs can be among the most challenging projects to build, and the most interesting to consider. The amateur radio world is no stranger to this, with homebrew radio designs that set some sort of line in the sand. …read more
