Q) When is the transmission of codes or ciphers allowed to hide the meaning of a message transmitted by an amateur station?
A) Only when transmitting control commands to space stations or radio control craft
NJ2X Notes:
Allowing encryption or other methods of protecting control commands to a space station or radio control craft helps assure the control operator stays in control. Physical access to an amateur radio in space is somewhat limited.
Adventure in amateur radio - the greatest of scientific hobbies.
