The CSU Chico Radio Site Tour

Now mostly abandoned - 1999

System Layout

Four ITFS transmitter sites are fed via full-duplex, 12 GHz Harris SS12000 FM analog video microwave from the main classroom/studio at Chico. The ITFS transmission is a 2600 MHz vestigial sideband television signal which is received by the learning centers via a rooftop dish, then down-converted and viewed on a standard TV receiver. Audio talk-back is provided via radio response channels back to the ITFS transmitter site and then returned to Chico via a six channel frequency division multiplex subcarrier system on the microwave. Some of the 12 GHz transmission legs use multiple hops before reaching the ITFS transmitter terminal. In addition, two translators are used to receive and retransmit the ITFS signal for extended coverage.
