Yes, but you have to be careful when powering up the K3 that 
the computer keying line is not key-down, which may happen 
if you are not running your logging program at the time. 
It's scary when you turn the radio on and it immediately 
goes into transmit! I think there is a software change in 
the works to prevent the K3 from transmitting when you first 
turn it on if the key line is keyed.

You might get away with doing it that way, but the shielding 
in a video cable is irrelevant to the ACC connector pinout. 
I think you would be better off going to Radio Shack and 
buying a plastic hood and male DB-15 and making your own 
nicely shielded FSK cable with a piece of RG-174.
