[TenTec] OMNI VI and EXTERNAL LOGIKEY K3 KEYER QUESTION

[Jliving39 at aol.com]

Folks,  
     I understand some transmitters do not perfectly  reflect the keying 
supplied to them and tend to shorten dots and dashes from the  keyer.  Any idea 
what, if any, correction (plus x number of milliseconds)  is appropriate for the 
OMNI VI.  I know I probably should be satisfied with  the internal keyer, but 
have a K3 and must play with it.  LOL.  Any  thoughts are appreciated.  
Please respond directly.   Thanks,  Jim, K4CFA
