FCC Technician Exam Question Of The Day (T1D03)

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 (i.e. you need a rocket to get there).  It is important to understand that codes or cipers are not allowed to hide the meaning of a message for other types of transmissions.
