Restoring Aluminum Knobs

  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 Frei...  READ MORE

Replacing C-frame fans

  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-...  READ MORE

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

The Codar AT-5

    For many years I have wanted to add this cute little AM transmitter to my collection, but since it was never sold in the US,  the number that came up for sale were few and far between.    And there was usually a buddy waiting in line, or a reluctance for UK sellers to bother with the hassle of shipping to their former colony when local bu...  READ MORE

Restoring the B&W 850 Plate Inductor
