Alex - Thank you so very much for the break down in costs - and what
you have is where I'm heading. I started with the basic $10 single
band RX, now just finished the V9.0 with my plans for starting the
RXTX next Jan. My plans are to wind up with what you have - perhaps
by the time I get there, a complete kit will be available - WITH a
soundchip on board - perhaps that's on possible, not sure.
Your statement earlier in thread of " The happiness, pride and self
confidence gained is, of course, invaluable." is exactly why we build
and homebrew stuff. I just enjoy melting solder and learning new
things - I realize I do learn slow, but something are better slow
{grinning}.
I have taken your list of links and prices listed and printed them
out for review and learning more. Not that I am planning to start
ordering just like that right now, but it will be a source of
learning.
Thank you for taking the time for such an in-depth reponse to my
question.

with
FCC requirements for harmonics):
