Don, Philip & Paul - Thank you guys so much for the help! It turns out I was confusing "infinite resistance" with "zero resistance" - it looks like I am good to go ahead with the next step.
I have a steady hand and I am good at following the excellent direction provided by Elecraft - so with your occasional help, this project should end successfully! Again, thanks for the clear and patient explanations. Burke Jones N0HYD Olathe, KS On Mon, Dec 22, 2008 at 9:08 PM, Don Wilhelm <[email protected]> wrote: > Burke, > > What do you mean by "nothing"?
