Yes folks, Jack and I collaborated on the design of this one. I started with a few logic gates, and Jack kept saying 'do it with no active devices - anyway, you can see the result in Jean-Francois website and judge for yourself.
Since Jean-Francois gave me credit in his posts, I thought I should pass along extra credit where it is due, and Jack deserves it. BTW, if I ever get both my K2s to the operating position instead of one in th eworkshop and the other for operating, I will be using this arrangement myself - not fully SO2R, but a reasonable compromise suitable for my operating. 73, Don W3FPR > -----Original Message----- > > There is one important step in the construction of the circuit that > should make it work well. > > Now it is important to take this step... > > What is the step? > > Contact W6FB in the Phone Sweepstakes - I need the VA2 QSO! > > :-) :-) :-) > > Good luck making it run.
