I can describe it, but can't find it for shit! I've seen it tons and tons of times on old cartoons (bugs bunny etc) and movies.. it's the old radio tower, the signal that goes off.. not anything but beeping, i'm not sure if it's a radio tower, or a transmitter, it's just the old original radio signals that were sent out.. sounds like morse code but faster and a bit more high pitched.. but you see like this tall structure sending off beep waves to wherever they're going.. sometimes at the beginning of a movie/cartoon as a production company.. That's the best I can do. Anyone know what i'm looking for / where to find it? I can't seem to find it, not sure if I don't have the proper name or what!
