𝑮7𝑰𝙕𝑼 𝑹𝙍𝑫Radio Propagation
My Ionospheric Path Monitor has been adjusted to plot chordal hops correctly using accepted physics. Signals across the equator usually stay airborne for a considerable distance before coming back down to earth.
New orange "glow zones" show the potential zones for the airborne reflections from the ionosphere at around 400km altitude.
