The A-R ident was a static white star on a black background, accompanied by a jaunty fanfare. It reminds me of the sound made by a bugle horn, but with added beeps, the morse code signal made by tapping out the initials "A" and "R". Incidentally, this is A-R's second ident – the original looked identical to this, but the jingle was different.
