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

All have responded as Childish Broadcasters (CBers) with

Shame on you all. You do nothing for the PR of Ham Radio.
