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!
