That would take care of my "dream keyer" idea. Heh heh heh. Actually, I have gone the other way with keyers. I eliminated it altogether by connecting a straight key directly to the K1 jack! It allows me to make dits and dahs my way. Also turned out to be a hardy choice for the trail. It is smaller, lighter and less fragile than any paddle of comparable quality.

One step away from a bug in that a string of dahs not just one dah comes out when you hit and hold the dah paddle. There is a circuit in "Solid State Design for the Radio Amateur" page 178 that I think does this using three NE555 'timer' ICs, VERY simple, with a pot controlling speed. The Dah, Dit and Spacing times can also be adjusted to suit the user's taste. The authors were discussing applications of the NE555, not keyers as such. CMOS ICs would keep the power draw low. 73, Geoff.
