The true test would be have the other end of the contact on the land line
and test with him over maybe a 10,000 mile path or the path one is
interested in
Since a contact is 95 percent propogation a good op at the other end can
possibly copy a signal down about 10 db below other signals.
50 years ago when I was at the 12th USASA field station I could copy the
weakest signal with 2 stronger stations on top of him.
