Fast-radio-burst-like signal traced to dead star in our galaxy

We may be a step closer to understanding the mystery of fast radio bursts (FRBs), as astronomers have now detected the first such signal from within our own galaxy. The radio burst in this case was traced to a highly magnetic dead star called a magneta… Continue reading Fast-radio-burst-like signal traced to dead star in our galaxy

Ham Radio Mobile Operations Circa 1919

You used to be able to tell a die-hard ham radio operator on the road by the number and length of antennas protruding porcupine-like from their vehicle. There are still some mobile high frequency operators that have respectable car-mounted antenna farms, but they have nothing on Alfred H. Grebe. In …read more

Hubble and ALMA mosaic captures stellar fireworks of star formation

Astronomers are celebrating the 4th of July weekend in their own trademark fashion – by releasing a new image of some cosmic fireworks. The spectacular shot is made up of a mosaic of radio and infrared images, showing a cluster of young stars exploding… Continue reading Hubble and ALMA mosaic captures stellar fireworks of star formation

Faux Vintage Radio Gets AirPlay Upgrade

There’s plenty of vintage-styled hardware out these days, with quality and functionality being mixed at best. [Huan] found such a device in the form of an attractively-styled Bluetooth speaker. Deciding he could improve on the capabilities while retaining a stock look, he got down to hacking.

The aim of the …read more

Rotary Phone Takes You Around The World And Through Time – With Music

Purposely choosing obsoleted technology combines all the joy of simpler times with the comfort of knowing you’re not actually stuck with outdated (and oftentimes inferior) technology. The rotary phone is a great example here, and while rarely anyone would want to go back to the lenghty, error-prone way of dialing …read more

Tackling Trunked Radio with Software

For those starting to wade into radio as a hobby, one of the first real technical challenges is understanding trunked radio systems. On the surface, it seems straightforward: A control channel allows users to share a section of bandwidth rather than take up one complete channel, allowing for greater usage …read more

Hidden pattern discovered in repeating radio signal from space

New clues have been uncovered in the mystery of fast radio bursts (FRBs) from space. One of these strange signals has been repeating seemingly at random – but with years of observation, an international study has now found a pattern hidden in the noise… Continue reading Hidden pattern discovered in repeating radio signal from space
