SKA: in Oz radio quiet is number one priority

“……protected from radio noise by most everything state and federal legislation can throw at it.”

“On a former cattle farm in the remote outback, scientists are laying the ground for the biggest science project of the next 20 years: a radio telescope capable of picking out something like an airport radar on a planet in another solar system. Turn on your phone at your peril, because preserving radio quiet here is priority number one.”

“At Boolardy homestead, the base camp for the observatory, there is strictly no wifi…. Televisions are brutally stripped of their wifi and bluetooth capabilities here before anyone is allowed to turn them on.  And this is still 45 minutes’ drive from the site proper, which is protected from radio noise by most everything state and federal legislation can throw at it.”

Quiet, please

If you’re studying radio waves – really old, weak ones from the dawn of the universe – what you don’t want is lots of people making very loud radio noise really close up. And visitors inevitably make radio noise because they use electronic devices, and all electronic devices make radio waves.

A car starting or an electronic camera clicking or a mobile phone searching for reception are much louder to the equipment here than any distant galaxy. Obliterating, even.”
