I've got several different "go" boxes. The first is a complete 20m station in a camera bag. I bought the bag some 30 years ago to carry a portable SW receiver and a scanner around when I traveled. I like it because it's padded on all sides with internal padded compartments. In it I have a Wilderness SST, gel cell battery, alternate AA battery pack, paddles, zulu clock, ear buds, notebook & pen, coax & wire antenna which can be set up as either a dipole, sloper, inverted V, or vertical.
