[Elecraft] K3/0 and CW

[John Huffman]

I'm setting up a K3/0-Mini to control my K3 remotely.  I would like to 
use an external keyer (Logikeyer) since I don't like the timing of the 
RemoteRig keyer. I have questions.

Does the KEY jack on the back of the K3/0-Mini do anything?  If it 
operates like a straight key I could send my keyer output to that jack.

I've seen suggestions to modify the cable to the I/O jack on the 
RemoteRig box and insert the keyer output there.  Does this interfere 
with the other I/O functions of the K3/0-Mini?
