Every radio nut will recognize three notes in this snappy tune!


  

Hudson American Corporation

Manufacturer of marine radios in the 1940s
Category: Vintage Radio
 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

    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

Replacing C-frame fans

Boatanchor parts from the home improvement store
Category: Technical
 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...  READ MORE

My SWR Dilemma

Learning about trap dipoles and SWR
Category: Vintage Ham Radio
 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

The WRL Duo-Bander 84

An "only 50 cents per watt" transceiver
Category: Vintage Ham Radio
  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

The Codar AT-5

A long-sought addition, enabling my mid-60s UK ham station
Category: Vintage Ham Radio
  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 buyers were close to hand.However I&...  READ MORE

How many got their start in radio with a Christmas gift?    And how many times did it come from the Sears or Mongomery Ward "Christmas Wishbook"?Mine did...the little crystal radio in the upper right?   Didn't work very well but was really cool!    The Remco Crystal radio was memorialized in this photo from about 1958 - age 7:  T...  READ MORE

   The B&W 850 is a kilowatt-rated tank assembly that was used in the company's linear amplifiers and sold as a component for many years.  Unfortunately most of the plastics available were not capable of surviving for 50-70 years and thus have deteriorated to the point they no longer support the coil turns properly and must be repaired.    Here's a typical example from...  READ MORE
