Dave, AA7EE, has a really nice blog article about his experiences with regen receivers. He writes about a regen kit he built as a kid (pictured above) and goes on to describe in beautiful detail a regen he built recently using a combination of old tech and new tech:

I agree with Dave when he notes that regens are unfairly thought of as mere novelties. My old "King's Speech" regen (below) is a very useful shortwave listening receiver and could easily be used for 40 meter CW contacts. It is even stable enough for SSB.

My first radio was a Knight-Kit Span Master: high-tech style on the outside, regen on the inside. Drove my mother crazy with the howling.
ReplyDeleteI wanted an AM radio for my birthday to listen to rock & roll. Sneaky EE dad says OK, but for the same money how about this shortwave kit? I fell for it, had my Novice a year later and my MSEE some years after that. Some sneaky dad.
