Ken, This sounds like your K3 is configured for DTR keying. Go to the CONFIG menu and look for the PTT-KEY parameter. If it is set for DTR keying, then when the computer boots, its BIOS raises the DTR line a few times which keys the radio.
Unless you are normally keying your radio this way, you should set the menu parameter to OFF OFF. I find it easier to turn it off between contests than to remember to go into test mode or unplug the cable every time I boot the computer.
