>From the ARRL "Contest Rate Sheet" issue of May 18: The "Falling Derrick" method of tower erection has nothing to do with using AA5BT as a counterweight. Rick N6BK uses this method to erect his 50-foot, 18-inch face Glen Martin Hazer tower and has been kind enough to describe the method at http://www.n6rk.com/falling_derrick_gme/falling_derrick_gme.html.
