Heathkit Built a Generation of Engineers. America Threw Them Away.

In 1947, a surplus oscilloscope kit arrived in a cardboard box with 437 components and a 112-page manual that taught you exactly how to build it — and exactly how it worked when you were done. For the next four and a half decades, Heathkit did that for radios, televisions, computers, and hundreds of other devices. It did not just sell electronics. It built the technical literacy of an entire generation of American engineers, technicians, and makers, one kit at a time. In 1992, the company closed. Not because it failed. Because the kind of customer it required — a citizen who assumed he had the right to open his own equipment and understand what was inside — was being quietly phased out of the American economy. This is the story of what Heathkit built, why America let it disappear, and what we have been paying for that decision ever since. The Last Frequency covers the electronics, the brands, and the everyday technology that shaped American life — and what it really meant when they went silent.
