----- Original Message ----- Got a note from Gary K9AY, he says no time to make the RAS8x2 switches, real work is too busy. So I suspect until Gary can make more they are not available. Dave Anderson, K4SV ----------------------------------------------------------
That's a pity, I was just about to order one! I haven't a clue of the methods of interlock switching the RAS8x2 uses but as it looks like we're going to have to make our own and my need to keep to simple click-clunk technology. I believe that using relays with a spare contact in such a cicuit that disables any other relay once operated, would do the job? Before I set about reinventing the wheel, does anyone have the knowledge or a basic circuit diagram for this sort of relay interlocking please? Tnx Dave _______________________________________________ UR RST IS ... ... ..9 QSB QSB - hw? BK
