Air traffic controllers and airline pilots use frequencies between 118 MHz to 137 MHz to communicate. More to the point, how might the workers themselves reach the top of the ridge (Wainwright, 1997). Military radar band nomenclature, L, S, C, X, Ku, and K bands originated during World War II as a secret code so scientists and engineers could talk about frequencies without divulging them.
