I like to listen to the old time radio programs on my antique radios. Hook it up to a cd player and have Fibber Mon, 09 Nov 2009 20:31:17 GMT W3FIS http://groups.yahoo.com/group/regenrx/message/8856 http://groups.yahoo.com/group/regenrx/message/8856 Ok, as soon as I get a few moments, I'll scan it in. I believe I already sent you the detector part. 73 /paul W3FIS Mon, 09 Nov 2009 17:26:54 GMT Richard Brunner http://groups.yahoo.com/group/regenrx/message/8855 http://groups.yahoo.com/group/regenrx/message/8855 You might be interested in my experience resurrecting an old RAL receiver. The original detector values were 510 pf grid capacitor, and 2.2 Meg grid leak Mon, 09 Nov 2009 15:34:28 GMT Prof. Arnaldo Coro Antich http://groups.yahoo.com/group/regenrx/message/8854 http://groups.yahoo.com/group/regenrx/message/8854 Sure amigo, it will be a nice addition to my already useful collection of regenerative receivers designs ! So far the best of the best built here continues to Mon, 09 Nov 2009 14:35:22 GMT ke4id http://groups.yahoo.com/group/regenrx/message/8853 http://groups.yahoo.com/group/regenrx/message/8853 Good morning, I have had great results with 10meg and 20pf grid lead resistor and capacitor in a regen BC-221 based set that I have mentioned before.

Ross http://groups.yahoo.com/group/regenrx/message/8852 http://groups.yahoo.com/group/regenrx/message/8852 I recall using 250 pFd and 4.7 meg in my Gottleib receiver (just check my old report). BTW, would anybody be interesting in me scanning in my 1960 Senior Mon, 09 Nov 2009 14:29:51 GMT Paul W. Ross http://groups.yahoo.com/group/regenrx/message/8851 http://groups.yahoo.com/group/regenrx/message/8851 Long ago and far away, I had a Heathkit oscilloscope that used similar boards for the main circuits. Tube system, of course. First time I had ever put together Mon, 09 Nov 2009 13:52:08 GMT laseraddict777 http://groups.yahoo.com/group/regenrx/message/8850 http://groups.yahoo.com/group/regenrx/message/8850 Hello-- Was just wondering if anyone has bought either the single- or the twin triode regen receivers/or kits from PV Scientific Instruments and how well they Mon, 09 Nov 2009 13:34:53 GMT kyoritsu http://groups.yahoo.com/group/regenrx/message/8849 http://groups.yahoo.com/group/regenrx/message/8849 This is rather long, has to do with the value of the grid leak resistor in a regenerative detector and the resultant sensitivity.

Weird, one entire triode is wasted. There has to be a way to use that last one, even if that's just paralleling it with one of the others. - John Mon, 09 Nov 2009 02:33:49 GMT kyoritsu http://groups.yahoo.com/group/regenrx/message/8846 http://groups.yahoo.com/group/regenrx/message/8846 Hue, I can't make much sense of it, beyond the grounded grid first stage (and the AF stages). And that grid leak resistor going to the B+? First, I'll have to Mon, 09 Nov 2009 00:06:31 GMT Hue Miller http://groups.yahoo.com/group/regenrx/message/8845 http://groups.yahoo.com/group/regenrx/message/8845 http://oernst.f5lvg.free.fr/tubes/1v1-el84/1v1_EL84_anglais.html The detector looks like just the conventional grid leak detector; I don't see that's its input Sun, 08 Nov 2009 22:14:24 GMT moNjP http://groups.yahoo.com/group/regenrx/message/8844 http://groups.yahoo.com/group/regenrx/message/8844 Ah yes, that was in this quarter's Sprat (G-QRP magazine). I really wish people wouldn't make up their own circuit diagram symbols!!
