This is a mobile emergency communications setup, it is primarily used to support the Western States 100 Mile Endurance Run at one of the remote locations.
I have ruggedized everything as a result of some bad weather last year. Lots of rain caused some damage to some of the equipment as a result of the moisture. The setup uses two 12V Gel batteries (in parallel), a Yaesu FT-8800 2m/70cm FM Radio, a Kantronics 9612 Plus TNC, a Stealth DC Computer and an Astron SRM-30M Switching Power Supply. Many of the components were made rack mountable using custom cut outs using a CNC.
A friend of mine helped out by creating the mounting system you see for the batteries below.
