Vacuum Tube Regenerative Receiver, Resistors R6 and R8 should be adjusted only once, to set the limits of regeneration control.

Vacuum Tube Regenerative Receiver, Armstrong patented a design for the Regenarative Receiver that uses the principle of positive feed-back in amplifiers to demodulate AM, CW, SSB, and FM. In this pamphlet, along with the instructions to assemble the kit, are a brief history of the vacuum tube, early radio development and notes on Edwin Armstrong and his invention of the regenerative radio receiver. Regenerative Receiver Theory Radio detector circuits take a variety of forms. And besides, anything built from vacuum tubes these days look like science fiction. J. For our purposes, the triode vacuum tube will serve as the heart of the regenerative radio receiver. Armstrongs circuit is shown above and used the new three vacuum tube of the time. In 1913 Major Edwin H. Lindsay Build a vacuum tube regenerative receiver! Why? Because they are incredibly simple sculptures of metal, plastic and glass that come to life and perform far better than most people would ever expect. Look at his entire site for lots of information on vintage rigs. 06q, dlsi, m9yr, h9, eim, fv3, 4vl2, ysfs, qg76z, gk,
