And this is my favorite, I kinda came up with this method myself (although, others on youtube have also come up with similar techniques, when I looked around):

Here's an Encrypted Communication method that's "Off Grid" (Encryption over Radio is illegal for some reason):

So...

Rattlegram is an app on iOS/Android that alllows converting a string of text to audio and play it over your phone’s speaker

Secure Space Encryptor (SSE) (known as Paranoia Text Encryption on iOS) is an Open Source app that can encrypt text, turning any string of plain text into ciphertext

So, a smartphone with these apps installed, and a ham radio is all you need. (Or if you want to test it all by yourself, you'll need two radios, two smartphones with Rattlegram installed)

Procedure:

1. Use SSE to encrypt text (both the sender and receipient need to share a password over a secure channel beforehand)
2. Copy-Paste the Ciphertext that SSE spits out into Rattlegram (Rattlegram will convert the ciphertext into an audio)
3. Play the audio over the radio
4. On the other end, use Rattlegram to turn the audio back to the ciphertext
5. Use SSE to decrypt.

Or replace SSE with OpenPGP, but the problem with PGP messages, is that they are much longer and you need to send multiple Rattlegram transmissions to send the entire ciphertext, basically its more time consuming. You want to finish your transmissions as soon as possible.

Voila! Off-Grid Encrypted communications.

(Again: Encryption is illegal over Ham Radio in many jurisdictions. I will neither confirm nor deny that I have tested sending an encrypted transmission 😉

Ususally, most governments will not care unless you started to use it for insurrection or something like that.)
