This identifier does not work for non-U.S. stations!
Some Canadian stations now work. In some cases, Canadian stations are
using the same codes as assigned to U.S. stations. Often, the "C" is
replaced by a "W". (so if you see a PI code that resolves to "WING" on
107.9 while the real WING is on 102.9, you're probably actually tuned to
CING.

There is no error checking in this JavaScript. Enter a nonsense PI and you
may get a callsign anyway.
