Abstract : HF radio waves at a number of discrete frequencies from WWV in Ft. Collins, Colorado have been studied in order to determine the dependence of Maximum usable frequency (MUF) on electron content and slab thickness. MUF is determined using skip phenomena of the WWV signal for the Ft. Collins - Danville path (1460 km). Electron content is measured at Urbana, Illinois and at Sioux City, Iowa near the midepoint of the path. f(0)F2 (from Wallops Island) data are used to determine slab thickness. (Author)
