Tom suggested I send this to the reflector also.

This is a good idea. The circuit will use up a 9 volt battery in a few ho=
urs. A few months ago I was demonstrating Spectrogram to the local Ham cl=
ub with the prototype noise generator. Unfortunately I had left it on and=
 the battery was dead. =20

Cohen's law the predecessor to Murphy's law "If it can go wrong it will g=
o wrong during a demonstration"

Oh well I muddled through with band noise and every one was still impress=
ed with the K2 and Spectrogram.

I might suggest that, instead of adding a "power-applied" LED, you might
just want to consider using a MOMENTARY pushbutton switch to activate to
noise source. This helps to ensure that you don't leave it running and ma=
y
lessen the chances of accidental activation as well.
