The first form of the network, built in the very late 1940s and early 1950s, used 23/24 channel ~2 GHz equipment from Federal Telecommunication Laboratories/ITT. During the 1960s many links were upgraded to 600-channel equipment (in 72-channel banks) over 8 GHz radios, all from Lenkurt. Another round of upgrades occurred in the 1970s around the Dittmer control center and computer control project, mostly to Lenkurt equipment with some Motorola used. |
