Cable History Highlights For This Year Range
Do you have $100,000 in 1975? If so, you could have purchaed the
Scientific-Atlanta TVRO receiver (earth station) which is 10 meters (33 feet) in diameter to pick up the satellite signals.
In 1975, James Grabenstein and William O'Neil demonstrate the first use of feed-forward technology to handle expanded channel capacity and higher frequencies.
This would make it possible to send channels into the frequency range above channel 13 (as cable channels 23-36 or K-W).
