"You may also encounter repeaters converting one of the digital subchannels of an FM station to analog mode on a different frequency. I haven't run into any of these running RDS but if it did, it would most likely show a legitimate set of call letters on the "wrong" frequency."
W293AH(106.5 KISS FM) in Huntsville, AL is a good example of this. W293AH is a translator with a HD parent station, WQRV HD 2, and uses RDS. The 7 character space displays KISS-FM. Strangely when I picked up the RDS call letters it said WLRH, which is the calls of another Huntsville station on 89.3. I don't know if this is a glitch or not, but perhaps this is another I Heart RDS screw up.
