RTS and DTR can be configured to assert PTT and key the K3.  It is 
controlled by a menu entry CONFIG:RS-232, and there are several choices 
including turning it off.  Turn them off in the menu and your problem 
should go away.  I think you have to have CONFIG:TECH MD set to ON to 
see the RS-232 menu entry.
