[ct-user] PTT keying when using CW

In the future, I want to avoid using vox in CW contests.  I am using
LPT1 for CT CW contests. I am already using pins 1,17,18 for CW keying.
Am I correct to assume, I need identical components for ping 16? Or
do I just need an additional 1-K resistor from ping 16 (PTT SLCT) to
base of existing transistor on pin 1?
