A strange star just got even stranger. In the midst of its death throes, the star V Hya has been belching out a series of rings and plumes of materials, in a pattern never before seen from a dying star.Continue ReadingCategory: Space, ScienceTags: Astr… Continue reading Dramatic dying star blows smoke rings in unique celestial show
Astronomers may be a step closer to solving a cosmic mystery known as odd radio circles (ORCs). New images, captured by the MeerKAT radio telescope, are the clearest and most detailed yet taken of an ORC, helping to narrow down the list of suspects as … Continue reading New data reveals secrets of million-light-year-wide “odd radio circles”
An abiding memory for a teen fascinated by electronics and radio in the 1970s and 1980s is the proliferation of propaganda stations that covered the shortwave spectrum. Some of them …read more Continue reading Owning A ShortWave Radio Is Once Again A Subversive Activity
Cross-pollination between different activities and industries can yield some pretty useful techniques or product combinations, and [Steve] shares some details on using ice fishing gear to make winter ham radio …read more Continue reading Ice Fishing Tent Makes Winter Ham Radio Comfy
There’s one component which used to be ubiquitous in every experimenter’s junk box, but nowadays unless you happen to be a radio amateur the chances are you may not have …read more Continue reading A Variable Capacitor For Not A Lot
As mysterious as fast radio bursts (FRBs) are, they’re now so common that they’re at risk of becoming mundane. But a newly discovered signal deepens the mystery with a few oddities – it hails from an unexpected region of space, and its pulses are about… Continue reading Ultra-fast radio burst could usher in whole new class of space signals
We’ve said it before and we’ll say it again: the best part about holding an amateur radio license is that it lets you build and use your own transmitting equipment. …read more Continue reading Retro and New Tech Combine in this Hybrid Ham Transmitter
Millimeter-wave Radars used in modern cars for cruise control and collision avoidance are usually designed to work at ranges on the order of 100 meters or so. With some engineering …read more Continue reading Machining Waveguides For 122 GHz Operation Is Delicate Work
Astronomers have discovered a bizarre radio signal coming from somewhere in our galaxy that can’t be explained by any known object. When it’s active the source gives off energetic radio bursts lasting up to a minute, every 20 minutes – which should be … Continue reading Bizarre radio signal repeating every 18 minutes discovered in Milky Way
If you read old antenna books, you’ll probably see the idea of phased vertical antennas. These use certain lengths of coax to control the phase of a signal going to …read more Continue reading Directional Antenna 3-Way
