Hi Gary,

The keyer state machine in the K3 firmware emulates the Curtis keyer 
chip if you set IAMBIC = A in the CONFIG menu (default). It emulates 
the "Super CMOS" keyer's mode B if you set IAMBIC = B. Based on your 
description, I think you'd like mode A.

Some K3 owners have asked for emulations closer to other keyers. 
Firmware can be changed ("small matter of programming"). Enough said ;)
