When I see those initials I think of the abbreviation for a shortwave pirate:
Radio Newyork International...
Wikipedia: "Allan Weiner of Monticello, Maine, USA, who had been a resident of Yonkers, New York, was a radio engineer who had operated both a licensed radio station and unlicensed transmitters. (snip)...As a result of this meeting, Weiner, Ford and other associates decided to replicate Radio Caroline as Radio Newyork International from a ship to be anchored in international waters off Jones Beach, Long Island, New York.
While the station was actually called Radio New York International, the name contraction gave Weiner the opportunity to use of the old Radio Northsea International jingles and thus call their station RNI."
