de KPH

Yes, a holiday greeting card from the original KPH, Port Reyes CA.    I don't have an exact date but I would guess late 50s or early 60s because it came from the estate of Roger Kaney (SK) who was W9AF when I knew him, but had been W9ZRU previously.  Roger was a retired marine radio operator when I met him in the late 80s, and even then would "stand watch" at night with receivers monitoring the marine frequencies which were still active then.  He showed me an article that predicted the end of shipboard Morse operation with great sadness, which of course came to pass along with the demise of the shore stations.  KPH unlike most not only survived in a new form but has prospered since and is still kept on the air thanks to the dedicated volunteers of the Maritime Radio Historical Association who have devoted uncounted hours to that end since 1999.    CLICK HERE to read more about the MRHA.

Before Roger's shipboard career began he spent a short time as an operator at KPH and was there over at least one Christmas, and got his "sine" included in the holiday card.   Pretty cool!

   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
