Don, Maybe a gate implementation might work ... you set me on a search that led me to http://fermi.la.asu.edu/w9cf/articles/ultimatic/ultimatic.html ... and that's probably the info you recalled. A quick glance won't do for this one: I'll need to study it a bit and see if it'll do the trick.
It appears that the K12 keyer could solve the problem, if the above won't. $17 for http://k1el.tripod.com/K12.html is fairly modest. I'll get back to you all shortly with the conclusion! Many thanks, Alan Alan D.
