Where are these equations? I have searched the ARRL handbook for Gamma and did
not find it. This is also the first reference to rho.

Rho is mentioned on page 5 of AN77-3. Unfortunately, as I have
written a long time ago in other threads, Hewlett-Packard's authors
(and divisions) could not agree among themselves on a standard
notation for complex reflection coefficient.

The same holds true for the rest of the literature. My personal (and
others') choice is to use upper case Gamma for the complex reflection
coefficient and lower case rho for the magnitude of Gamma.

If this was standard then there would be no confusion.
