Sending any encrypted comms is against FCC rules. That includes using a brevity type coding via voice, digital or CW. With that written, if the SHTF I wouldn't worry about the FCC trying RDF you. \"/

On the other hand, if you were to send digital brevity messages using lets say Fldigi, using a yagi antenna and the lowest power setting to get out there; although illegal, nobody would catch ya'. If you did this, I would also use a pirated out of the USofA call sign like one from Cuba, Mexico, Canada to name a few.  ;)


How would they even know it was a brevity code and not just jibberish?
Blessed be the LORD my strength, which teacheth my hands to war, and my fingers to fight: My goodness, and my fortress; my high tower, and my deliverer; my shield, and he in whom I trust; who subdueth my people under me.

Psalm 144:1-2

you get one ahole listening to your brevity code and he hears you give out your call sign. Which you should do every 10 mins legally and now hes crying to the FCC that he cant understand you and you are talking in code LOL.
With AmRRON and ARES we post our brevity codes online on our websites so its public for anyone to see. If anyone were to break into our conversation on the air we would explain that we are using brevity codes due to an emergency or training and they are publicly available on our website at what ever location we posted them on.

 :sarcasm:
use Morse code to transmit Hollerith code in Chinese?
post the code base in several different web sites that aren't linked.
-
use Morse code to send Swahili - if anyone complains, scream 'cultural bias'.
-
have even more fun and send Morse in SolReSol.
-
i think the point is to be somewhat private without going overboard or breaking the law.
you need to make it harder to break your code than the timeliness allows.
if the idea is constant security with constant conversations - use a commercial license - run it though a latop vocoder of your choice into your radio and transmit scrambled digital.  break the simplex chain - one side of the conversation is via the method mentioned above and the replies sent via email or text in a different language. 
if the idea is a go code - use plain language - 'time to pack for our vacation' = get ready to bug out, or the inlaws are coming over.
-
my personal favorite i plucked out of a spy novel - transmit voice on a common carrier, like GMRS FM - and send the interesting part in the subaudible tones - there are more than 255 of them (enough to send in most letter based languages) So, talk about the weather while typing the actual conversation into your laptop for xmit as subaudible.
