[Elecraft] K2 Noise Blanker (KNB2) Demo

[John McClain]

Hey Tom,
        I took you up on your offer and visited your web page.  That
is quite a shack you have.  I recognized the K2 and the Yaesu but they
were about the only thing that we have in common.  I must say that
your desk is much nicer than mine.  I'll give you a quarter for it.
