What an intriguing circuit - I read up on the "Spontaflex" on this web site: http://www.spontaflex.freeserve.co.uk/autoflex/autoflexpage1.jpg I had not heard of it before. I wonder how you demodulate CW signals - do you allow the circuit to oscillate as you would do with a conventional regenerative circuit ? The basic Spontaflex seems to be an AM receiver. 73 Hugh M0WYE
