[TowerTalk] Skewed Path to BQ9P

This is reverently called the SKEW path. Been around a long time. I
remember using it on 20 meters in the late 1950's from Long Island. At the
same time, K2DGT (now W6PU) put up a 3 element full size Telrex monster on
40-Meters in Islip, LI and  most mornings he sat there running JA stations
on 40-Meters with the beam at 220 degrees. Many were skeptical because they
couldn't hear the JAs but they were TRUE BLUE QSOs!

Yes, I hear that path many times a year on 40 meters and sometimes even on
80/75 meters!
