If I remember correctly, the original RDS feed the stereo pilot to the
DBPSK block as it had the correct symbol phase. From this
https://www.cgran.org/raw-attachment/wiki/RDS/rds.png it looks just
like band passing the pilot and dividing to the correct rate.

I'm not feeding it the stereo pilot. I just use a fractional
resampler to resample the few kHz at 19.0kHz/8 --this gives 4
samples/symbol into the DBPSK block.
The spectrum looks roughly
correct--a double-humped structure either side of zero.

exactly 19.0kHz/8?
Are you feeding it the stereo pilot or generating your own?
Have you tried looking at the signal with an FFT scope to see if there
is anything there or if it looks distorted or something?

I'm having trouble demodulating the RDS signal that comes along
with a lot of broadcast FM signals these days. I know that there's
"gr-rds" that has already done this, but I wanted to do my own just for
personal education.
I spent a lot of time yesterday playing with it,
and I can't get anyth
