Author: R.J.Edwards G4FGQ © 26th April 2006. Or given values of the elevation angle and height. Of an ionospheric reflecting layer this program calculates the one-hop ground path and radio path distances between the transmitter and places where the radio wave returns to Earth. Without reflection at a 90 degree vertical angle, is also an input to the program. The reflecting layers in the ionosphere have a profound influence on the radio-wave path. There are five principal layers: D, E, F1, F2 and F&#4...
