[Milsurplus] Older USAF airborne receivers?

[Jason White]

Someone out there would probably know this. I'm familiar with the
ARC-5 sets that the WWII era aircraft carried, but what sort of
receivers were employed in the SAC era USAF aircraft? I'm thinking
specifically about the HF range. There is a 60s era B-52 crash site up
on Elephant mountain in Maine that I got to visit once, and there is
scads of comm gear all over the place but not much identifiable except
for one piece of equipment I found with a Collins logo. I of course
didn't touch it out of respect (as countless others before me). I'm
assuming since it was left there in the 60s that it must not be much
of a secret.

Anyone know, or could point me to a good reference to these sorts of questions?
