I could occasionally summon this message by mashing the touch-tones on an analogue telephone in the late 1980s and early 1990s. "RA" may refer to Rockford Airport, which would explain the notion of a "special service air channel," but that's as close as I can get. It's been a mystery for almost 25 years. Anyone from the area have any explanations, or perhaps remember this message as well?
