Radio amateurs used to have a sign a "Declaration of Secrecy of 
Communications" before we could get our ticket i.e. we could not reveal 
anything that we happened to hear...

And boy, I heard some juicy things :-)  The old analogue (and 
unencrypted) cordless phone system was quite entertaining at times.

Any CBer with a scanner could sand-bag, but it was Amateurs who copped the 
blame, because of our antenna arrays.

Heh heh; I got blamed on a couple of occasions for clobbering a 
neighbour's TV set, but the simple fact that I was in Tokyo at the time 
(and on another occasion being interstate) made little impact upon her (I 
made damned sure that everthing was switched off).
