DR570T.2

Separate Audio for the Alinco DR570T.

There is a way to separate the audio in the Alinco Dr570T.
The high side of both the main and sub bands can be tapped right
off of the volume control circuit board.

There are nine pins on the connector of this board.
The center one is the high side of the sub band.
Right next to the center, going towards the ground (brown) wire,
is the high side of the main band.

The volume control can be easily accessed by removing the bottom
cover. The end of the board sticks out from the front housing.
There is a small piece of clear plastic protecting the board.

The difficult part is routing the wires out of the cabinet. 
Since I am using this as a base unit, I removed the power cord
grommet and brought the wires through that hole.

I can now run packet off the main band using this connection for
the audio feed while monitoring the 440 band through the rig.  
Also by using an amplified speaker the audio can be physically
separated.  Good Luck.  73's, JIM.  N3KHM @ KA3NVP.WPA.PA.USA.NA
