What are some secure ways to communicate on radio or without wifi/cell service?

Hi where I live it is illegal to encrypt your CB radio. However I could get a sateite device that allows me to text anywhere but without wifi I don't think there's a way to use end to end encryption and I don't think routing the phones would be good enough.

Note : I don't have wifi or access to data or cell service

I think your only option is to ignore the law and encrypt your radio communications.

Careful with encrypting CB radio, it is easy to determine the origin of the signals back to your home, automobile, or whatever you are transmitting from. If merely encrypting it is illegal, I suspect that would be grounds for an arrest warrant in many jurisdictions. Kinda defeats the purpose of encrypting your sensitive info if the opsec practices you use get you popped!

Best bet is to use locally generated wifi meshnets. The range is shit compared to CB (meters vs. kilometers), but if you want encryption that'll have to be the way you do it I think. F-Droid has a number of smartphone applications for this, which means you can use existing smartphones as relays. there are linux programs too. I would recommend finding a router and putting open source firmware on it, then setting up a meshnet with it. You could chain a few together, create a zone of access, and use it to communicate in a small area, but it's probably way too short range for your needs. Unless you're dumpstering the relays, it could get kind of expensive pretty quickly too.

I hear CB radios with encryption built in can be purchased from China, but you may run into international arms export treaty law depending on your country of purchase.

I have some Baofeng digital radio lying around, ordered from Alibaba. There's some loophole around it though. For example, I was able to pick up shipment, but according to the laws it's prohibited to use.

IIRC, as long as the package is not declared, you're fine.

Word of wisdom.

I used to mail things from coast to coast for worse lol. Weed, Xanax, MDMA, card cloner, key grabber, etc. We even mailed an actual Stingray ISMI catcher to our hackerspace for research, all the way from Vancouver, where it was illegal for civilian to possess. None were declared. Fun fact, I still order weed online from gray market stores even weed was legalized. Didn't get caught.

Doing it discreetly and right under their nose is always better.
