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

[Mr. Carlson] is truly an old radio surgeon. The evidence? He recently restored an 83-year-old DeForest radio by transplanting an identical chassis from another similar radio. The restoration is fun to watch, but the 7D832 radio dial looks amazing. The …read more
By studying the twinkling of stars, astronomers in Australia have discovered a huge cloud of cold gas in our galaxy, not far from Earth. This invisible mass could provide new hints about where to find the universe’s missing matter.Continue ReadingCateg… Continue reading Cold gas cloud in our galaxy could be hiding universe’s missing matter
For many commercial broadcast radio has lost its luster, leaving an unknowable number of perfectly serviceable AM/FM radios to lie dormant. But they don’t have to. As [Dan Gebhardt] shows in his recent hack, integrating a Bluetooth audio receiver into …read more
