Oh S Band was being used quite a bit back then :) Even 6-7GHz was in use
by the Telcos (AT&T mostly) Heck T1s have been around since the 60s but
a lot of folks outside the telephone companies didnt know it! T1 was
primarily for trunking between locations that were close
enough...microwave was used for the long hauls (remember the old 2600Hz
BLEEP you used to hear at the end of a LD call when the distant party
hung up?)
S Band was chosen because of the noise problems of trying to comm
through the Van Allen radiation belts at UHF. Of course they used S Band
for everything...Data, Video and voice....
