And I just dug out my HD radio. It was a gift when I worked in radio up north, but it's not been generally hooked up down here (too many radios, too little space!).
Tuning in 101.9 on the HD radio, a little unit by an outfit named "Directed", and using a wire/dipole antenna, I pick up 101.9 in HD with no trouble at all. In that mode, I get all kinds of station/artist/title info. Now, I believe that I recall that the info that HD radio sends is a different technology than RDS. It may use the same files, but the technology is different, right?
So could it be that 101.9's RDS data is stuck/broken/faulty, while the same info is scrolling normally on the HD side? I can recall occasionally prodding the engineers at our stations to give a kickstart to the RDS data every now and then.
