A very interesting explanation with history and math combined! I’m not sure if most of HN cares about rf things at this level but I was very happy to see a discussion of transmission lines, and a lot of the discussion of the trades of parameters to improve a Morse code transmission.
RF is definitely interesting - it's the closest thing to black magic in electrical engineering (all went over my head during my degree...that's why I ended up in power systems :^) ).
Yes, especially since in power transmission the distances are large; if you turn on the power at point A, then point B will not immediately receive the power and this is quite measurable.
