You can also use a separate detector with this regenerative circuit. On this receiver at http://www.b-kainka.de/bastel3.htm you have the same regenerative stage which you have used in the noisy regen. But there is a seperate audion detector used. The regenerative stage and the detector a coupled onto a tap of the coil.

Cool circuit, some time ago i've built it for shortwave on a breadboard in 15 mins using a polyvaricon cap and a molded inductor, and it worked immediately. Seems to me quite identical to the russian "universal demodulator" (Polyakov, I think), see http://ok1ike.c-a-v.com/soubory/det.htm (in Czech, use google to translare). The audio output is taken from a one stage fet amplifier (or detector?), and it's recommended to use low noise fet. Maybe an improvement for your "noisy?" I've dismantled the noisy after listening a little, but I'm going to try the fet mod. See later, 73 de Michele IZ8JJI

Jason,

I'm glad to hear you built the Noisy Regen and got it working OK. Send me a picture if you happen to take one, or shoot me a URL and I'll link it to this page.

Regards,

Alan

That is a cool little projct i build it from your diagram and it worked thanks
