Bob W1GWU, who you may remember as one of the three founders of Hosstraders and the voice on the PA system, sent me this link to lots of ham radio equipment manual pdfs. It even has some 50s Collins stuff.

He did a great job at it. It's been many years but I can still hear his voice in my head when I think of Deerfield.... especially in the early days when hams were paging their buddies day and night. I think they just wanted to hear their calls announced... :-) Nowadays it's mostly quiet on the PA. (ahhhh.. tranquility)
