All,
What I love about this group is the "real time" method of comparing and
discussing recording methods. Your photos, sounds and sonograms are
wonderful Rich. What are the two pieces of pipe for? Perhaps you could
have a smaller block than 1 foot square, say 8 inches square, for the same
effect? Easier to carry around maybe? (Walt, I could not access your frog
sonogram - address showed an error.)
