Hi jjw, that signal process is very easy verify, but before you must know the Plasma physics, if you don't know that, that's say the reason why the signal is captured for the plasma and get the earth curvature that practical meditions are not random, theory predicts that you can deduce that equation by using Maxwell equations in plasma structure and you can see 3 conditions in that equations, for begin, all plasma in gas state has a oscilating frecuency you can calculate with this equations and according for the input frecuency signal you will see this 3 cases:

1) If the input frecuency is less than the plasma frecuency the signal is reflected

2) if the input frecuency is greater than the plasma frecuency the signal is refracted in a angle

3) if the input frecuency is equal than the plasma frecuency the signal is captured for the plasma and follow his way

The Ionosphere has severeal layers of very densities and in consecuence many resonance frecuencys from 7,8 Hz in the more lower Heaviside layer to some MHz in the top layers
You can verify and I verify that waves follow the earth curvature using a single test, you can modulate a 7,8 Hz signal with another wave and get it an another world position and register times and follow the trayectory of the pulse, remember that waves finds in the antipode, with many people we have verify that speed of 470000 Km /seg app
About equations here is very large put them and send you for email

This single test show there is phenomena more speed that light and with theorical explanation, of course at start you send waves with a speed less than light speed but there is another waves travelling for Ionosphere, traditional EM waves you send only activate the process
This waves in scientific terms are more speed than light are called longitudinale, scalar waves or more specific, magnetodielectric waves

Thanks, bye
