[Elecraft] K3 and Utility question

[John Watkins]

When I have the K3 turned on when I start up my laptop and it happens to be in SSB mode the com port I use for the utility apparently causes the PTT to send about 5 longs T's over the air.  If I am in CW no problem because I have told the rig to come up with VOX off.

Is there a setting that will prevent this unattended transmission while in SSB mode?

Thanks, John N0EVH
