The Sonar MR-3 mobile receiver
The Sonar Radio Corp. of Brooklyn NY is a well-known manufacturer of Ham, CB, and Marine Band radios over a period of several decades, and it's products were always well engineered and of good quality. But despite several attempts, it's ham radio products never really managed to excite hams enough to plunk down their hard-earned cash. The SRT serie... READ MORE |

The Multi-Elmac CD-10 Project
In 1958, the Multi Elmac Company was riding high on the ham radio waves. The company had seen an opportunity to provide feature rich but affordable transmitters and receivers to hams itching to "go mobile", which was all the craze. Instead of sticking a converter in front of the car radio like many competitors did, Elmac produced full-blown receive... READ MORE |

Mystery Transmitter
I didn't set out to buy this homebrew CW transmitter, it was included in an auction lot that I wanted so I had to take it to get the desired item. But even though I always like to see good quality homebrew gear, this one is just a mystery. Most of the transmitter, including 6CL6 oscillator and buffer stages and a 6146 PA are built on a sub-chassis that is cle... READ MORE |

The Vector VR-50
Most hams are aware that Herb Johnson W6QKI founded Swan in Benson Arizona to make single-band SSB transceivers and then moved his operation to Oceanside CA where Swan thrived throughout the 1960s. Swan merged with Cubic Corporation in 1967, and Johnson managed Swan as its subsidiary until 1973. Johnson founded Atlas Radio in 1974, with the assistance of Southcom Intern... READ MORE |

Hallicrafters AT-10 Antenna Tuner
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 order... READ MORE |

The Clegg Interceptor receiver and Allbander converter
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... READ MORE |

6AG7-6LG Novice Transmitter
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...

Trio Multibander TX-88A
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 th...

My SWR Dilemma
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 ... READ MORE |
