Digital encryption in the Motorolas, Yaesu, Kenwoods, Boofwangs are clearly an illusion, and same for the basic scrambling in analog/FM modes.

Stay mobile
Never mention names
Have and keep a convention for nicknames
Use codes that are private to your group
Have a logic and change your channel or frequency very often (there's plenty in VHF or UHF)
Don't share the same codes among different groups
Send pointless encoded messages to confuse the spy even if they are incomprehensible
Stay hard to predict and have a random schedule
Use dead drops, could be anything
One-Time Pads are also simple to decipher a ciphered message
Go cheap, if your equipment is seized by the enemy or spy, it is not exploitable
finally, just have a good memory, i.e, it's good we are in a fandom, can make it based on tropes or obscure references as memorizing techniques you agreed upon. that helps. Let's offer Discord a cup of tea!
