New post "why-signals-bend" with ten hand-rolled canvas scenes (LOS, Earth curvature, Fresnel, knife-edge and rounded diffraction, refractivity profile, ray tracing, duct trapping, duct types, and the real 65 km QTH-to-W5HN/B path with 4/3-Earth bulge). Also drop QSO/em-dash conventions from prop1 and the "written by humans" footer line. |
