I got to play with one of those WW2 walkie talkies. They were built
tough enough to drive a car over - more like ten pounds. Remarkable
piece of gear.
And last time I played with military radios they were still that weight.
It's the idiot proofing that adds the weight and size.
I once wondered why our Bergens were steel framed instead of being more
like the Al civilian ones. Until I saw one of the guys get his down the
mountain by placing it on the ground and giving it a big kick.
