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!

Phil, Are you using batteries? Or a power supply? If a power supply, try using just batteries and see if the hum is still there. If you are using batteries,

I retouched a large number of solder points on the board and then retried the radio. Well, it fired up and I got a very loud audio hum(which varies as I turn

Re: Ten Tec 1253 - assembled, but only get a hummmmmm
Thanks all for your suggestions. I'll do some more checking and see where that takes me. I'm learning more than I thought with my first outing in radio

one way to test for a bad solder joint is to get a small steel screw driver even a small nail will do and with the radio turn on touch every pad so that you
