    Most radio fans know the history of KDKA  but maybe not "the rest of the story".In November 1920 the Westinghouse Electric and Manufacturing Company began operation of a radio broadcasting station, KDKA, in East Pittsburgh, Pennsylvania, often described as the "Pioneer Broadcasting Station of the World."  KDKA is generally considered to be the first commercially...  READ MORE

   The microwave network constructed by AT&T Long Lines and other telecommunications companies in the past 50 years were engineering masterpieces using state-of-the-art technologies and some were designed to withstand nuclear attack during that Cold War era.     This is a non-hardened site on top of a mountain in upstate New York that existed long enough for graffiti taggers t...  READ MORE

In 1917 a missionary named William Cameron Townsend went to Guatemala to sell Spanish Bibles. But he was shocked when many people couldn’t understand the books. They spoke Cakchiquel, a language without a Bible.   He believed everyone should understand the Bible, so he started a linguistics school (the Summer Institute of Linguistics, known today as SIL) that trained people to do Bible ...  READ MORE

The Mosley Commando II

Made in England and scarce even there
Category: Vintage Ham Radio
The Mosley CM-1 receiver is quite well known and not especially hard to find in the US even though it was the only radio produced by the company that has been well-known for antennas since 1939.   Or is it...?A full-page ad (advert for you on the other side of the pond) appeared in the RSGB Bulletin in 1963 for a nice looking and very capable SSB transmitter called the "Commando II&...  READ MORE

   I'm not ready to publish a description of exactly HOW it works, but 20 minutes effort with scissors and tape produced a prototype  Droplet Energy Generator that allows me to say for sure that IT WORKS!I duplicated the design shown in this video.   I wrapped a scrap of plastic in aluminum foil, then applied a strip of double-sided tape and to that attached a piece of PTFE thread-...  READ MORE

   When I was first licensed in the 1960s in Nebraska, two groups of hams were commonly heard on the air before those with jobs got off work - other teens like me and the disabled hams.   Some of my earliest Novice ham buddies were blind students at the Nebraska School for the Blind in Nebraska City, and there were many other visually-impaired hams, all of whom were exceptional operators, e...  READ MORE

   Old style mica capacitors were used in the pi-net matching sections of several vintage transmitters and the combination of age, heat, and high RF currents have made them likely failure items.   My Collins 32V-2 transmitter was to the point where it would not properly load to full power on 75 meters so something had to be done.   Mica capacitors are no longer made but fortunately new...  READ MORE

   I found myself wanting to convert various frequencies to other frequencies and wanted a cheap and easy solution, so I designed a simple "universal converter" using the NE-602 and a programmable oscillator from Epson.  I'd used the same combination in hundreds of "RANVerter" SDR Upconverter projects since my Dec. 2013 QST article and knew that while there were limitatio...  READ MORE

   It's always a challenge to hold PC boards during assemly and testing.  After purchasing a magnetic holder from Amazon  I realized I wanted more and could easily make as many as I wanted using inexpensive 3 mm hardware from eBay and some strong "fridge magnets".     All that's needed is to epoxy a standoff to the magnet - both tapped and threaded ...  READ MORE
