[SFDXA] Hammarlund & Hallicrafters

[Bill]

  Hammarlund Built the Best Ham Radios — Then Made One Bad Call

In 1910, a Swedish immigrant named Oscar Hammarlund opened a small 
manufacturing shop in a Manhattan loft. Within two decades, his variable 
capacitors and radio kits had become industry standards. By World War 
Two, nearly ninety percent of all American electronic military equipment 
relied on Hammarlund components. The SP-600 receiver became the 
benchmark for military and commercial operations worldwide, and amateur 
radio operators considered Hammarlund the gold standard.

  What Happened to Hallicrafters? | The Radio Every Boy Heard the World On

In 1933, in the dead center of the Great Depression, a sixteen-year-old 
wireless operator from Boston named William J. Halligan started a radio 
company in a rented room in Chicago with nothing but two trucks' worth 
of parts and a dream. He called it Hallicrafters — a combination of his 
own name and the word handcrafters — because that is exactly what he 
intended to do: build the finest shortwave receivers ever made, by hand, 
one at a time.
