Also for things like remote control of repeaters etc.  If some wombat
started playing music over it (or worse), I merely commanded it off.

Naturally I changed the key every so often, because the idiots regarded it 
as a challenge to decrypt my commands (I'd quickly learned to avoid replay 
attacks by using some sort of a rolling-key scheme), but strong crypto 
was, and still is, a definite no-no.
