Well, yes. There are builders and there are users I think. If you
enjoy building, you spend most of your time doing that.If you enjoy
operating, you do only the minimum necessary building. The valve gear
mostly satisfies the artistic creation desires, at least in my case. I
have done about half a dozen QSOs with my 7 MHz 807 set and the funny
thing is I still build CW transmitters when I am not really all that
competent in Morse code... :-) Explain that if you can!
