Played a lot with the link above from Alex25 (it's in German). Very interesting, even for Germany. So I see the following needs:

- storing the AF frequencies
- getting TMC working (will be hard, I think)
- (personal opinion: re-inverting the bottomline in tunermode)

I could imagine that coding can be done in hijack, isn't it? I'm not sure if all festures of the tuner can be controlled via some hijacks. On top of this, it shouldn't be a big fun for Mark to code this, because he lives in the USA (is it?) and therefore cannot receive those RDS signals.
I would like to assist an experienced Empeg coder, myself don't know enough for this (no /dev/rds where I can read things from).
