Here are some pics of how I configured the rig for the DXpedition. I was able to shoehorn everything into a Pelican 1520 case - KX3 , KXPA amplifier, PX3 panadapter, power supply and DC distribution. The whole arrangement was shock mounted to a piece of polycarbonate. I used the SOTABEAMS stands to get the viewing angle just right.
I can then take everything out to setup on a table or on the case itself as shown below. I kept all the wires as short as possible. The battery just connects to the blue Powergate. The whole arrangement case included weighs 9.6 kilograms.
