  • Re: Optimized single FET receiver

    *** I found I could pull the frequency down to below 3500kHz. With a Colpitts/Clapp oscillator i get down from 3580 to <3450 kHz. Typically the amplitude is

    I just installed a ceramic resonator in one of my 602/386 DC receivers in place of the VXO crystal. With a 7200 kHz resonator I was receiving about 7018 to

    Hello Nzerowva, I experimented with "pulling" the frequency of a ceramic resonator (original frequency was 3580kHz). I found I could pull the frequency down

Group Description

The purpose of this group is to facilitate the exchange of information, experiences and ideas aimed at the promotion of and encouragement in operating, designing and building these amazing receivers.


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!
