Thanks the responses Tom and Tree. I checked the signals at the port with no 
electronics connected. All appears normal there. I will check my electronics 
when I get home tonight.

One thing I did notice while I was playing around was the the 'CW after PTT 
delay' value is still active even with PTT disabled. Probably won't bother 
anybody. It was just something I noticed.

Here are the results of my probing:

STROBE: 
PTT disabled = only active with CW characters or ctrl-shft.
PTT enabled = same as above plus always active when keyboard CW active.

PTT: 
PTT disabled = never active
PTT enabled = same as strobe above with PTT enabled

KEY: 
PTT disabled/enabled: only active with CW charaters or ctrl-shft.


Note: CW is always delayed by the PTT delay value.
