65 Years as a YL Ham
This all started when I discovered a fantastic collection of vintage photo QSL cards on a Google+ site – I’d encourage every ham to spend some time looking through this amazing bit of history: https://plus. google.com/115747543308902188110 The photos capture a wide range of ham gear and stations from the spark era through the 70’s, and nearly eve...

Multi Elmac PS-500
Some pieces of vintage ham gear are not really unique, but are so rare as to almost never be seen. The Multi Elmac PS-500 power supply is an example, it was sold as an AC power supply for the A54 and A54H transmitters in the mid-50s. There's nothing special about it - just a big transformer with 5 volt rectifier, 6.3 volt filament, and 500 volt secondaries. Two... READ MORE |

My experience with the Nouveau 75
Mini-review of the Nouveau 75 by W9RAN I like it, warts and all! OK, maybe not quite that "mini". ..here's a few of my impressions of this innovative kit from the 4 State QRP Group. I've been interested in amplitude modulation of a class E PA for some time and after Dave Cripe said to stay tuned for the next 4SQRP offering, I wasn't too surprised to see ... READ MORE |

International Crystal's KB-1 Citizens Bander for Kit Fans

Phasing SSB transmitter alignment - the easy way!
Equipment manuals and handbooks of the 1950s and 60s were filled with complex oscilloscope screens and discussion of ripple and as a result proper alignment of a phasing rig eluded most hams. But a clever New Zealand ham, Fred Johnson ZL2AMJ was able to see what everyone else had missed, and published a short note in the NZ ham magazine in 1972 that makes the process simple and...

Bearing puller for pennies
Finding myself in need of a tool to remove a bad bearing on a blower from a linear amplifier I first tried the usual automotive type gear puller but it wasn't able to get underneath this small 5/8" OD bearing. So I improvised a tool that took 10 minutes to make, cost a few cents, and had the job done in no time at all The secret is wedges sold at the hom... READ MORE |

W9RAN Field Radio
In the early days of aviation radio, transmissions originated from the ground using the longwave transmitter also used for homing, and pilots acknowledged by wagging their wings. It didn't take long to realize the benefits of having transmitting capability onboard the plane as well, and the first generation of aircraft radio used the low HF band. Given today'... READ MORE |

I find the show-biz association of the founder of Allied Radio, Simon Wexler, to be rather fascinating. What started out as a supplier of crystal set parts led to a family that became a major force in the entertainment industry and in Chicago business...including many recognizable names: "Allied Radio (now known as Allied Electronics) is a company with a long history. On A... READ MORE |
