If you remember it, you were there!
If you remember "Beaker Street" it's about the best news ever! Otherwise this will seem like going to someone else's high school reunion...In the late 60s, for kids living in "flyover country" in most small towns in the midwest, there were not many local rock and roll radio stations that could be heard during the day. But with sunset came the ski... READ MORE

COLOGNE, GERMANY—According to a Live Science report, archaeologist Erich Classen of the Rhineland Regional Association and his colleagues were looking for a Roman villa in western Germany when they unearthed a Soviet spy radio that had been sealed in a metal box and hidden along a path through what was the Hambach Forest, just a few miles away from a nuclear research center and military air ...

One even Dachis doesn't know about!
A while back I acquired a six channel HF transceiver made by the Radio Industries division of Hallicrafters, probably in the 1960s, called an SBT-20. It is capable of 20 watts SSB or 5 watts AM (or CW with an optional board) in the range of 2-12 MHz and thus was probably aimed at commercial and light-duty military applications. The radio could by ordered with fu... READ MORE
It's not just for VHF!
I'm always thinking about interesting combinations of equipment to try out on the air. One day while rearranging the shack I was getting ready to connect my Globe Scout Deluxe back up with a Collins 51S-1 receiver when the LED (the energy-efficient version of the old light bulb) came on.When I first started playing with DVB-T dongles back in 2012 I wanted an upconverter so I ...

Classic circuit with some modern twists
There's a good chance that more homebrew ham transmitters have been built using a 6L6 than any other tube, and when combined with the superior performance of the 6AG7 oscillator, it's a hard combination to beat (click here for an explanation of the 6AG7's benefits)I'll be adding more info about this project soon, but one of my goals was to reproduce what was a budget-friendly...

A time capsule from JA-land
All who operate AM in the midwest know and probably have talked to Masa, AB9MQ, who is a very active AM operator. Having become interested in ham radio while still living in Japan in the early 1960s, Masa's memories of the "dream rigs" is a bit differen than most US hams, and because the markets were still quite regional at the time, much of the ham gear...

Manufacturer of marine radios in the 1940s
I enjoy playing with old marine radios that operated in the AM mode between 2-3 MHz. This was the standard for "ship to shore" radio and telephone service from marine radio operators from after WWII until about 1970 when SSB was phased in and AM became obsolete. Through this era a number of manufacturers were major players including RCA (Ra... READ MORE
Bead blasting is the secret
I've always thought that knurled aluminum knobs were a high-class option for radio gear, and while they are more durable than plastic they do accumulate tarnish, corrosion, and grunge from dirty fingers over the years and start to look poor. Fortunately it is easy to restore them to a new attractive appearance using a bead blaster. Mine is a Harbor Freight floor-standing... READ MORE
Boatanchor parts from the home improvement store
It's not often that you can buy a replacement part for a vintage transmitter or amplifier off the shelf at the home improvement store, but this is one example. And since it's not a perfect drop-in replacement, here's now I adapted a new Broan-Nutone BP-27 bathroom-kitchen exhaust replacement fan to fit into a Johnson Desk Kilowatt.These small shaded-pole "C frame...

Learning about trap dipoles and SWR
When I got my Novice license in the fall of 1965, my dad had also decided that as long as he was taking me to the classes at Blue Valley Amateur Radio Club in Seward, Nebraska, he might as well try for his license too. I was fortunate that not only were my parents supportive of my ham radio interest, but my dad could build anything. So the first thing was a 40 f... READ MORE
An "only 50 cents per watt" transceiver
Go Mobile! That was an attractive marketing message to 1960s era hams who were enjoying the fun of operating SSB mobile, and WRL knew a low-cost rig that didn't have to be hauled back and forth to the car would be a winner. Heathkit and Swan had already proven that with their single (mono) bander transceivers, but what if you're heading out in the middle of th... READ MORE
After the conclusion of World War II, there were only about 300 radio amateurs in Japan. In the year 1952, the JARL reported that only 30 provisional licenses were granted. Realizing the value of ham radio in developing a technological workforce, Japan introduced its entry level Class 4 licence in 1959 - it would prove to be the world's most succ... READ MORE
