You can heard some strange noise if you call 140.66 in some area, the one I know is 'The Connecting Bridge'.

In your codec, have you ever wonder what the last row and last columm for? Try calling frequency 140.07 to talk to the staff. Unfortuately, the conversations are in Japanese, so I don't know what they are talking about. There is no English voice-overs available.
