In the EP-3 the Nav had to load
all of the friggin crypto on
all of the damn radios. And if memory serves me correctly that was seven radios, some of them needed their own crypto and some needed two. Once you got it down it took about 15 minutes (you had to key each radio on three different channels for each crypto loaded...........:icon_rage), but the first few times it took 45-50 minutes. And this is before the automatic keying machines, it was an individual strips one by one in each friggin/damn/cursed radio.......and you had to do it all over again in flight when a new Zulu day turned over in PACOM............It was a real pain in the ass........
By the way, all of this was carried in a very heavy double-locked orange metal breifcase that weighed about 150 pounds.......okay, about 40......it was still a pain in the ass to haul around.
And we used all three nets all of the time, especially the highest one.
