Hi Mike, >From K3 Owner's Manual in the section describing menu entries, p.55: CW WGHT 1.15 Adjusts element/space timing ratio (weight) for the internal keyer. Additional functions of this menu entry, via numeric keypad (Advanced): Tap 1 to select SSB -CW (default) or SSB +CW (allows CW in SSB modes). [highlighting is mine] 73, Mike, K8CN
