Feed through capacitors

Matt Osborn
In my attempt to complete the Poor man's Spectrum Analyzer, I found
that I need some feed through capacitors to shunt RF off the DC power
supply lines.

I've been unable to find a source.  That neither Mouser nor DigiKey
seems to offer them has me wondering if I'm looking in the right place
or for the right things.

I wanted the screw in types that fit in a hole in the Hammond box used
to hold the RF board.  Mouser does sell SMD types, but I don't think
those are particularly useful for this application.

Does anyone know where I might find a supplier?

PS. It seems as though the feed from this reflector isn't working.
I've seen less than 5 posts since Friday evening.  I was able to post
a test message that made to the reflector and back, so I'm still
subscribed, etc.

Check any SPAM filters you have running for one that's decided that messages
with certain common words (like "Elecraft") are SPAM <G>. Also, you can go
to the Elecraft web site and look at the message archives to see if the
count matches what you are getting. They post an archive maintained by AC6RM
that is current to the day.
