Dear amigo Ed--- Please notice that you have a fixed 200 pF capacitor to return to ground the tickler coil !!! My advice is to try to use instead an air spacedacoro33100
Dear amigo Frank W4NPN Nice to hear from you and learn about your interest to build vacuum tubes regenerative receivers. Amigo from Italy , Cris, circuitacoro33100
G'day Prof Coro (and others), Thank you for your invitation to try the 6EJ7 (& co) pentode as a detector. I'll say "no" until I have test equipment that willles.au49
Regenerative detectors are simple enough for children to build, yet can challenge even the most experienced builders. Usually, the receivers utilizing these detectors require a minimum of parts. However, some can be complex indeed, and can be incorporated into superhet designs such as the Super Gainer and the Regenerodyne.
Since 1990 there has been renewed interest in the old fashioned Regenerative receiver, many are even being used in active communication service. Join us as we explore these classic circuits and use them as they were intended to be used. You just might get hooked.
Note: Regenerative receivers embrace a wide spectrii of subjects, and span a wide area of time, thus thread topic can range widely, from circuit dynamics to old radio lore. It is hoped that Olde Tymers might feel free to share their own stories and experiences of their past with the ol' stand-by 'genny, and as well the Not So Old Timers.
Folks just starting out are encouraged to share their questions, successes, and frustrations too. Remember: for every page that Thomas Alva Edison (Al) entered in his journals about his successes, he devoted reams of pages for his failures. He studied his mistakes and turned them into successes. I think we can learn something from Al. And each other!
