Path

Station:

My antenna Their antenna, assumed My noise Their noise, assumed Noise belongs to whichever end is listening, so the two directions of this circuit do not use the same one: my noise affects only “I hear them”, their noise only “they hear me”. Each category marked “from the locator” is a guess from the settlement class at that square (GHSL, ~5 km) — the two ends are looked up separately; pick one yourself and it stops guessing for that end. Heights are fixed at 0.25λ — the shipped ITSA-1 pattern set has no height variants. ITURHFProp (the second engine) has no antenna files installed, so it stays isotropic; both noise categories reach both engines.

O-mode X-mode solid glow altitude ×4 for visibility ink and thickness = that ray’s own SNR on the same −30…+10 dB scale as the matrix cells, so rays are comparable between cells
