How the HELL do they shut down the truckers "radios"?
You can't shut down the Earth's ionosphere, which does the propagation. There is literally no infrastructure required -- nor can any be taken away -- between one trucker's radio and another trucker's radio dozens of miles away. They are probably using CB radio, 27 MHz. Similar to 10M ham radio band.
It should be child's play to monitor CB radio (or whatever they're using) to get around ANY media blackouts.
When I read that, I said to myself, "They probably mean they shut down their radio
programs." I was thinking of programs like the sat radio Truckers Channel* on Sirius XM and maybe some podcasts. Also, while they cannot shut down the ionosphere, they can certainly use jamming technology on the Aussie equivalent of CB and ham bands.
*I have tried to call the Truckers Channel, but never succeeded in getting on air. I wanted to say, "Here's a tip for truckers. If you want to pass another truck, you actually have to go faster than the other truck." I can't count the number of times I have been on two-lane interstate while some rig takes 10 or 15 minutes to "pass" another rig going only ½ mph faster than the rig he's trying to pass.
