Don, many thanks for this.
The mist is at last clearing.  I have the CBLP3Y connected as per the P3 manual 
and all works well.
I now understand that the 'PC' jack is predominantly for firmware 
updates/Elecraft Utility and remote operation.  It was naming several 
connectors 'PC' across all the boxes that had me confused about where the shack 
PC should connect.  It's on the USB and staying there ;-)

Will buy/make a suitable Y cable to connect the antenna controller to the P3 PC 
connector.
Thanks again,
73, David G3WGN  M6O

David,

Download the latest P3 manual and look on page 5.  You will need the CBLP3Y 
cable.

The KAT500 and KPA500 use the AUX cables and not the serial data.  The PC 
connection shown in the KAT500 manual is for connection to the PC for use of 
the KAT500 Utility and has nothing to do with the normal serial data between 
the K3 and the P3.

To get the serial band data to your antenna controller, use a "Y" cable at the 
PC connector on the P3.

There are other ways of connecting things as shown on page 6 of the P3 manual, 
but you will have to connect the PC to the PC connector on the
P3 and not use the internal USB to serial adapter included in the KIO3B, but 
you will still have the USB soundcard that is internal to the K3.

73,
Don W3FPR
