Ever wondered how they transmit your TV signal?
David Kilpatrick from TXAustralia takes us on a detailed tour of the old decommissioned 10kW analog TV transmission system at the Artarmon facility in Sydney. It is still used to transmit digital TV. How it all works from the broadcaster video input to final transmission output up the 180m broadcast antenna. Plus some teardowns of the old equipment that’s been used to transmit the Channel 7 TV signal in Sydney since 1981.
Copper rigid coaxial lines, waveguides, filters, splitters, combiners, converters, transmission valve, power supplies and all the equipment necessary to transmit a 10kW analog or digital TV signal in a major city like Sydney.

A look into Fairchild Semiconductor’s integrated circuit manufacturing from an educational promotional film broadcast on television on October 11, 1967:
Fairchild Semiconductor presented its new products and technologies with an entrepreneurial style, and its early manufacturing and marketing techniques helped give Californias Santa Clara County a new name: Silicon Valley. It was one of the early forerunners of what would become a worldwide high-tech industry, as evidenced in this short promotional film.
