... Noise you're not listening to is noise you can't hear. Therefore noise _outside the passband_ of your receiver is noise that doesn't matter--assuming thatdavidpnewkirk
Thanks for the input. Those methods work very well for a broadcast receiver or one where the tuning range is wide compared to the frequencies in use. For
... Ok... I know that electrolytic caps are polarized so they are wired with the negative lead connected to ground and that fixed caps can be wired either waydavidpnewkirk
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!
