The K1EL keyers also support Ultimatic mode. They are small inexpensive
PC boards. I use the K12 to provide Ultimatic mode, much easier for me.
I too would like to see the KX1 and K1 rigs provide Ultimatic keying.
The K2 is not a problem for me - the external keyer works fine, but it
would be nice to have Ultimatic 'inside' the K2 and K3 too.

Mike,
It's my understanding that the MODE is a function of the chip being
used. At this time I know of three Ultimatic units. The cube keyer that
goes with that mini Palm paddle key (the newer cube), the offerings from
Jackson Harbor - I think the PK4 chip (that's used the new Palm), and
there's a keyer for about $17 that is constantly for sale on that
Auction site (I think it comes up when searching on QRP) Unfortunately,
I don't believe the older PK3 chip is plug to plug compatible. That is,
you can't take a keyer based on the PK3 Chip and plug in the PK4.
I think the circuit board for the basic keyer (not a lot of memories) is
pretty small. So you might be able to stick in inside the rig and just
wire it to the key jack - or you can install it as a small box at the
key end - sort of in-line with your key.
