It is so exciting with a human in Control, your own brain doing all the work instead of watching a Black Box. Amazing stuff some would say. First Time did you say ?? I recall reading your article about a 700W TX you built and you state it BLEW UP several times before it settled down !!

Or write software, or data modes or whatever. I get no enjoyment , satisfaction, or anything from even contemplating using that morse stuff. It is a foreign language I was forced to learn to get a G4 Licence. Forced to do in much the same way I had to do French O-Level at school, we couldn't opt out. So please stop shouting that you consider yourself vastly superior to anyone else as you can speak a foreign language.
