Bruce Perens writes "FCC is currently processing a request for rule-making, RM-11699 (PDF), that would allow the use of Amateur frequencies in the U.S. for private, digitally-encrypted messages. Encryption is a potential disaster for ham radio because it defeats its self-policing nature. If hams can't decode messages, they can't identify if the communication even belongs on ham radio. A potentially worse problem is that encryption destroys the harmless nature of Amateur radio.There's no reason for governments to believe that encrypted communications are harmless. See hams.com/encryption/ for more information."
