I built this circuit and it seemed to work pretty good. It
certainly isn't as good as a superhet or a DC rcvr but for the
amount of parts involved it does pretty good picking up BC stations.
 I built mine on a Radio Shack coppper protoboard but probably
should have built it "ugly" style. It might have eliminated some of
the squeeeels :-)

You will need to keep the shaft of the tuning cap at ground and also
put a plastic knob on it to keep down the "hand" effects. Also the
circuit really hates soft batteries so make sure they're fresh.

I dug it up when I built and probably still have it on file. Bill's
reprint was identical to the original EDN version. Also the article
didn't offer much more insight.
