Go to CONFIG and select CW WEIGHT. Then press the "3" key on the numeric
keypad to toggle it.
It doesn't seem to make much of a difference for me.

Using the most current K3 F/W, I compared the New versus Old QSK
configuration using a dual-trace scope and an external keyer modified with a
buffered output for scope triggering.
Under the "Old" QSK setting, the CW envelope rises ~ 15 ms after contact
closure versus ~ 19 ms for "New." Under "Old," the keyed RF envelope more
closely matches the external contact closure duration.
Listening in the headphones, I detect little difference in weighting and T/R
recovery time. I haven't had time to compare the two modes under varying
AGC and band conditions, but unless I detect some anomaly, I am leaving my
K3 set for "Old. QSK."
