Via the ARRL: Virginia Radio Amateur will Recreate 1906 Fessenden Christmas Eve Broadcast

The Canadian inventor, experimenter, and entrepreneur Reginald Fessenden has been credited as the inventor of radiotelephony.

Via HACKADAY: WWII Aircraft Radio Roars to Life: What it Takes to Restore a Piece of History

I’ve been told all my life about old-timey Army/Navy surplus stores where you could buy buckets of FT-243 crystals, radio gear, gas masks, and even a Jeep boxed-up in a big wooden crate. Sadly this is no longer the case. Today surplus stores only have contemporary Chinese-made boots, camping gear, and flashlights. They are bitterly […]

Via HACKADAY: Retrotechtacular: 934 MHz CB Radio

The radio spectrum is carefully regulated and divided up by Governments worldwide. Some of it is shared across jurisdictions under the terms of international treaties, while other allocations exist only in individual countries. Often these can contain some surprising oddities, and one of these is our subject today. Did you know that the UK’s first […]

Via HACKADAY: Hacking Transmitters, 1920s Style

The origin of the term “breadboard” comes from an amusing past when wooden bread boards were swiped from kitchens and used as a canvas for radio hobbyists to roll homemade capacitors, inductors, and switches. At a period when commercial electronic components were limited, anything within reach was fair game. [Andy Flowers], call sign K0SM, recently […]

Few occupations are more fraught with peril than predicting the future. If you are a science fiction author, it might not matter, but if you are trying to design the next game-changing piece of hardware, the stakes are higher. It seems like, for the most part, even if you manage to get some of the […]

via HACKADAY: Retrotechtacular: The OSCAR 7 Satellite Died and was Reborn 20 Years Later

If I were to ask you what is the oldest man-made orbiting satellite still in use, I’d expect to hear a variety of answers. Space geeks might mention the passive radar calibration spheres, or possibly one of the early weather satellites. But what about the oldest communication satellite still in use? The answer is a complicated one. Oscar […]

via HACKADAY: The Great Moon Hoax — No Not That One!

Humans first walked on the moon 50 years ago, yet there are some people who don’t think it happened. This story is not about them. It turns out there was another great conspiracy theory involving a well-known astronomer, unicorns, and humanoids with bat wings. This one came 134 years before the words “We chose to […]

via the ARRL: Centenarian Radio Amateur’s Efforts Helped Pave the Way to the Moon

The Nashville Tennessean newspaper recently featured the story of a 104-year-old ARRL member who contributed to NASA’s effort to put the first humans on the moon 50 years ago this month. Cary Nettles, W5SRR, of Columbia, Tennessee — who calls himself the nation’s oldest rocket scientist still alive — was a NASA project manager and research engineer on […]

via HACKADAY: Live Apollo 11 Transcript On eInk Display

There are few moments in history that have ever been recorded in more detail or analyzed as thoroughly as the Apollo 11 mission to the Moon. Getting three men to our nearest celestial neighbor and back in one piece took a lot of careful planning, and recording every moment of their journey was critical to […]

A newly-digitised classic film of the 25th Anniversary Congress of the IARU is now on the RSGB YouTube channel. Taking place in 1950, the Congress was attended by many well-known amateurs from around the world.
