What do you think amateur radio does? Why do you think that broadcasting your location, and that you're looking to get information from somewhere other than the approved sources will end up in anything other than tragedy? What information do you think could reliably be provided with amateur radio in a situation like this?
Sure, if you are smart enough. Maybe mount a small transmitter on a tree then use a directional antenna at a very low power and use the tree as a repeater.
Or use NVIS, which at least makes triangulation harder.
~5m antenna during the day, 10m at night for a simple dipole antenna
I'd be more worried about them being able to triangulate the radio signals though. If they can jam GPS, surely they can detect a 100W signal around 14MHz.

And you know, I'm fairly sure being able to talk to the outside world makes it so that you can at least get information out to others.
Pray tell, what methods do YOU have to bypass a shutdown with privacy and no reliance on ISP and resistant to jamming?

That way, we might end up with enough nodes such that mesh networking comes within reach.
