Mal - the ultimate satisfaction for some of us is to construct Tx / Rx
and other things that work first time, and possibly use them, or give
the deigns awy to others who will.   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.
