I repeat "Read it again, Gary." the example I gave is an
illustration......read what it says and apply your thought process
instead of your reactionary ....If you did read the thread you would
know where the question developed...or perhaps you can find someone to
read it to you so you don't miss anything,since you admit in your post
that in fact you have not read it all.
And FYI, the illustration I used is derived from Ralph Holland's
Amateur Radfg 1996 ....
