George, Thanks for the settings you quoted below on your mic. Yes, my mic actually works and I am learning that my errors may be in thinking that I do not have to talk close to the mic.
I am continuing to experiment today but it will have to wait, taking my wife out on a bird photography trip up in the Skagit Flats. 73, phil, K7PEH On Mar 5, 2011, at 11:19 PM, George A.
