Every once in a while, you find something cool and cheap. Or free.
The guys at NASA's history department have done it again. "Read You Loud and Clear" (13 MB Adobe Acrobat ".pdf" format) is about the Minitrack, SATAN, STADAN, Mercury and other tracking and communication networks that were deployed for the space program.
What I've read so far, a variety of frequencies (HF, VHF, SHF) were used as well as a variety of modes. (radar, SSB, teletype) for tracking, telemetry and comms.
Looking forward to exploring the book more. I guess maybe 40 or 50 years later, some of this could be homebrewed... sounds like fun.
