The other thing you can do is to go into the CW WGHT menu, tap the 4 key and select VOX AUTOOFF. This turns VOX off when you turn the radio off and so the PC won't key the radio while it (the PC) is booting up. You have to push VOX to turn it back on, which is a bit of a pain, but I put a message in the banner message telling me to do this. This only works if you turn the K3 off and then back on before booting up the PC. Cheers and 73, Fred
