Is there actualy a timing problem with kx3 cpu ??
Keying with 30wpm and more the dot-dash ratio is incorrect - very short dots like a machine gun :)
Compared to my k1, kx1,k2 and k3 the cw from internal keyer of kx3 is terrible

Dick, do you think there will be a solution in firmware soon ??

Elecraft does not use separate keyer chips.  Morse code generation is performed by the main microcontroller.

Since I am interested in the Ultimatic mode and the Bug mode I have on my Pico keyer, can anyone tell me (I am mostly concerned with the KX1 and also the KX3 keyer chip):

1)
Do the Elecraft keyer chips have these modes?

2)
Is the Elecraft keyer keyer chip (drop-in) upgradable to a Pico Keyer chip?
