RDS PI Code Calculator (for USA)
This identifier works for U.S. stations (both full-powered and translators) and most full-powered Canadian stations.This identifier does not work for stations outside the U.S. and Canada! This page
is designed to calculate the correct PI code value for your station's callsign. The R(B)DS standard (Source) assigns specific Program Identification (PI) codes to each U.S.
station, mapping them from the call letters. The point is to ensure two stations with the same service area don't end up with the same code. Otherwise, it is theoretically possible some radios might regard these
stations as interchangeable, and automatically tune between them when one's signal fades. There is no error checking in this JavaScript. Enter a nonsense callsign and you may get a PI code anyway.
To check this result: Go to this page. Enter the hexadecimal PI code in the upper box. Click Calculate. Your station's callsign should appear
in the lower box.
