I think CB is very undervalued today. For SHTF you should have every option available to you. We've seen in other countries where the government turns on it's people they use signal jamming and shut down the internet.
Remember if you get jammed there are ways around it. Also often your incoming signal is jammed but you can still transmit and get help incoming if you have a network of people established ahead of time. HOPEFULLY you have enough power to bypass their Mobil jammer. Or you can find the guy or guys with the Mobil jammer and shut it down. But that's a discussion we probably shouldn't get too deep about on INGO.
It's gonna be uneasy not hearing replies to your sos calls but you have to keep the faith and rely on your training. You have been training right?
I have been training for this. I talk to myself every night.
