I suggest that it still lies in the areas of LC filters, resistor
networks and individual transistor (or valve) operation.
One traditional area that I did not mention, but perhaps should
have done, was the tradition of gentlemanly conduct, a tradition
that is seen to be lacking in _ALL_ those who have responded
to this thread.
All have responded as Childish Broadcasters (CBers) with
gratuitous and infantile personal remarks.
Shame on you all. You do nothing for the
PR of Ham Radio.
