[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
It’s easy to imagine that once a spacecraft leaves Earth’s atmosphere and is in a stable orbit, the most dangerous phase of the mission is over. After all, that’s when we collectively close the live stream and turn our attentions …read more
Back in September last year, astronomers made a splash when they announced the discovery of phosphine in the atmosphere of Venus, which could be a sign of life. But a new study has found that a different gas could explain the signature detected, and th… Continue reading Biosignature on Venus likely to be mistake, says new study
Astronomers have captured stunning new high-resolution radar images of the Moon, using an experimental instrument mounted on a ground-based telescope. This proof of concept test paves the way for a more powerful radar telescope that could see as far as… Continue reading Experimental planetary radar captures incredible high-res Moon images
It sometimes seems as though antennas and RF design are portrayed as something of a Black Art, the exclusive preserve of an initiated group of RF mystics and beyond the reach of mere mortals. In fact though they have their …read more
If there’s anything about amateur radio that has more witchcraft in it than the design and implementation of antennas, we don’t know what it would be. On the face of it, hanging out a chunk of wire doesn’t seem like …read more
