Otherwise, how do I know that I have permission to listen to 89.5 in the car? It's available... but if that doesn't imply permission, then what would? Do I have to write the radio station a letter, asking if I could kindly listen in to their broadcast?
You do not have permission to listen to arbitrary RF signals that fall onto your property. For many years, elevator music was broadcast via Subsidiary Communication Authority subcarrier. This is a subscription service, and it is illegal in the US to receive it without paying a subscription fee. You have indeed been granted permission to listen to 89.5. It is in the FM radio band which has been set aside for public broadcasts. It is also illegal to listen to someone elses cellular phone conversation, or to their cordless phone conversation. Since these things are fairly easy to listen to, most services have moved to using encoded or encrypted signals to make decoding more difficult. Also, decrypting a signal without authorization violates another set of laws as well. David -- [email protected] http://www.kernel-panic.org/cgi-bin/mailman/listinfo/kplug-list
