*** This is - put more clearly than I could have - the point I was
aiming at by suggesting that the problem hadn't yet been adequately
identified. I understand that getting CBU at strength on just the coax
isn't right, but that also isn't directly indicative of what the
problem is. What Rick suggests would be much more conclusive and is
cheap.
