Hi,

I built a 1-transistor regenerative reflex receiver back in the
late '60s. I used a OC170 transistor salvaged from a scrap Ferranti
computer board, which keeps it on-topic I suppose :-)
I wish I'd kept the board now...probably an Atlas one :-(

Just remembered - it was the "spontaflex" ,- it was Sir Douglas Hall and
there is a web page devoted to his circuits.

Hi
A quick search shows that these are at:
http://freespace.virgin.net/spontaflex.reflex/
From looking at some of the text, these are a combination
of a reflex with some regenerative feedback to increase the
Q of the tuning circuits.
I suppose one could write programs to sing through such
a receiver on their clasic computer.
