I have two "ancient" documents covering LOS Microwave and Tropo Scatter
comm. They are both about the size of a Sears catalog (speaking of
ancient!!) They are both military documents, one has a large number of
charts and nomographs. They are too large to copy but I would be willing to
lend them to anyone wishing to research them in detail.
