I didn't want to create such an elaborate or heavy setup for my own portable ops, but I did need something better than the old Yuengling beer case that I've been using.
On the IC7200 Yahoo group someone mentioned that the radio will fit into a Harbor Freight #69318 18" x 6" x 13" aluminum toolbox. Today I took a ride to the nearest HF store to look at them in person and bought one. Note that HF sells two very similar toolboxes. The #69318 is the one that comes with pluck-to-fit open cell foam and dividers. The #69315 appears to be identical but does not come with the foam.
Here is the one I bought:
As shown in the sticker on the box, it also comes with an insert for holding tools. I removed this because I needed the interior height.
It took only a few minutes to pluck out the foam pieces so that my radio is nicely cradled in the box:
An oblique view shows the depth relative to the radio and LDG IT100 tuner:
(The tuner is secured to the radio with Gorilla tape.)
The box closes with a bit of pressure on the lid and keeps the rig from moving around. I have copies of my ham and GMRS licenses tucked behind the egg crate foam in the lid, along with a print out of the ARRL band plan.
Many go boxes are watertight. This one is not, but my use for it is transport to and from a campsite in my truck. Likewise, it's only one part of my portable setup: I still need to bring a separate power source, netbook, and of course, the antenna and mast. But, this will be easier to transport in my truck, easier to carry, and it was cheap. With a 20% off coupon the toolbox was about $25 out the door. I might pick up another one for the laptop and assorted other gear.
