[ARC5] How Edwin Armstrong invented the superhet

[Hubert Miller]

I saw a comment that the superhet was easier to build. Wrong. That's why so many manufacturers in the late 1920s to late 1930s aiming for the "more affordable" market offered TRF and regenerative radios. That "Clipper" radio offered in the today auction that was mentioned here, is a mid 1930s glorified regen  built big with lots of knobs, but at a fraction of the price of a National or Hammarlund superhet. No tracking, virtually no alignment, minimal engineering and construction expense.
