Reply to "PW Whistle Detection Circuit"

I think I posted too early in the morning - I mistook the R2/C2 part of the circuit for the "RC filter" part. When I was writing my post I kept wondering why the R and C were backwards in the filter but chalked that up to only one cup of coffee at that point - doh! Everything makes much more sense now...my thanks to everyone who posted! I've got an order accumulating for DK so will add a couple of the less common parts to it and then breadboard up a sample to see how things go.
