My plan was to use a variation of the manhattan style of component placement, by cutting-out spaces from a grid of squares on the copper surface of the pc, as I did with the oscillator/amplifier project described in the previous post. Because he was so forthcoming about his ups and downs in his regen saga, I decided that I’d try following in his footsteps for my first scratch-built regen. John Fuhring has an extensive and entertaining account of his attempts at building a Charles Kitchin “ Scout Beginner’s Receiver” regen kit. Last year I built several regens, some successful, some not: John Fuhring’s Regen Receiver – April–October 2016 Over the past year or so, I’ve taken the “at least one” part of the title literally.
Although the regen is one of the oldest receiver designs, it’s still widely used in garage door openers, walkie-talkies and wireless “internet of things” devices. These are relatively simple radios to build and they can receive any type of modulation, from AM to Single Sideband, to FM. Hackaday recently had a post called “ Everyone Should Build at Least One Regenerative Receiver“.
