In 1976 Motorola put phones in the MAST/DUSTOFF UH-1H’s at Ft. Lewis. This 35K20 “helped.” That was amazing then.

Loved being in Signals..there was always some pretty neat gear around to handle...former 31m20

My uncle had one of the early phones,that thing was big as a brick and it was quite expensive to use

35K? Damn, you are old! :0) That there’s a 25U’s job these days.
