R = # of Radios
C = # of Containers
H = # of Hams
R x C x H = the number of ways to pack a portable radio.
Translation = a lot of ways to pack a radio
So here is my solution for carrying an ATS4B and an MTR to the top of the mountain, complete with power supply, ear phones and key.
Pelican 1020 and 1040 Case
I put a thin layer of spongy material on top to keep the radios from moving around in the box. So there you go, my main rig and a back-up.
