On my K2 there is a J5 Conn. 'AUX AF' right up front next to the CONTROL
BOARD.  The holes are there to put in a connector.

Are both pins 1&3 of the same audio level; and what is that audio level?

Hi, Daniel,

If you care to pay a look to my web site www.qsl.net/ea3blq/int_dig_ang.htm.
you'll see how I use the balanced audio output present at J5 and convert it
from balanced to unbalanced to feed the incoming audio to my Digital
Interface for the K2.  

Greetings from Barcelona, Spain
