tripleJ should have RDS, I haven't seen it on my MK2 tuner, only on the MK1 some time ago. It occationally flashes on, I think there may have a problem with transmission itself.
I haven't known MMM or Austereo to have RDS. they're too backwards.
I'd love it if they could have RDS come up with the track title.
