Ron,

Thanks for the complement; I enjoy seeing what I can do to make
something fit my needs.

I don't have a particularly noisy site but I have the radio sitting
on a shelf with another shelf just above it which makes the top
firing speaker in the K2 more difficult to hear. So I added the
amplifier to connect to a front facing speaker. I probably don't need
the extra audio level, but added it because I don't know what I might
connect it to in the future.

73,
