I've heard Elektor did a similar project in 1996

Elektor 04 / 1989, P. 14-17     RDS: UKW WITH TEXT AND DATA
Elektor 04 / 1989, P. 58-60     RDS demodulator SAA 7579 T
Elektor 12 / 1989, P. 94-95     Decoding RDS data with the PC
Elektor 12 / 1989, P. 96-97     RDS DECODER SOFTWARE FOR THE ATARI ST
Elektor 02 / 1991, P. 24-28     RDS decoder for 8032
Elektor 06 / 1992, P. 58-59     RDS demodulator SAA 6579T
Elektor 01 / 1994, P. 8-15      RDS DECODER using M68HC05
                                (based on Motorola app note AN460,
                                which I already have.
Elektor 03 / 1996, P. 48-53     RDS DECODER using PIC
Elektor 03 / 1996, S. 35-36     RDS-Demodulator/Filter TDA7330 datasheet

These may not appeared in non-German editions.

However the AN460 code does not manage the tuning and re-tuning,
so the RDS features that need this (e.g. retuning to traffic
announcements) are not implemented. That was 8Kbytes of code.
I expect the PIC project is even more limited.

I expect to need a beefier micro. An H8, or Toshiba TMP87CM71F.
The latter has on-chip VFD and keypad drivers.
