The difference between iambic and Ultimatic keying is that when you hold
down both paddles, the Ultimatic keyer sends a series of elements
corresponding to the last paddle closed instead of sending alternate dits
and dashes as an iambic keyer would. For example, the sequence L on, R on
would cause an iambic keyer to send di-dah-di-dah..... An Ultimatic keyer
would, however, send di-dah-dah-dah.....
If you count the number of paddle movements, you can see where this might be
advantageous. There's no advantage when sending a K. The sequence is R on, L
on, L off, R off for both iambic and Ultimatic keyers. Take X, however. When
using iambic keying, it's R on, R off, L on, L off, R on, R off. With
Ultimatic keying, the number of paddle movements is the same as for the
iambic - R on, L on, L off, R off. - a savings of two paddle movements. You
just hold down the left paddle a little longer for the X then for the K.
Another keyer that now supports Ultimatic keying is the N0XAS PicoKeyer
(www.hamgadgets.com). It's only $18, and fits in a mini Altoids tin. I have
no affiliation with the company; I just think it's a cool little keyer.
73!
