[Elecraft] Ultimatic Keying.

[EricJ]

 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.
