A few years ago the banter on this list often was in reference to the material 
in the ON4UN book and it surprises me so many here now don't seem to have it or 
use it. It is truly the bible of 160 meter operation for both little squirts 
and big guns and anyone who wants to operate on 160 really should use it. It 
would also enrich the dialog here as we once had if more questions were based 
in pinging the book first.
