I have just completed the translation to English of my description of
RDS decoding. It is now available at

Hi Jean-Michel and List:
As promised here is my RDS reception flowgraph. It is based on a USRP device
(I have a B200) so you may want to swap that for whatever device you are using.
I’ll leave it to you to develop the decoding program. Mine is written in C,
but you can use whatever you want.
Hi,
you might also want to have a look at gr-rds.
I collected some links here:

Hi Jean-Michel:
Certainly! It took me a couple of months of reading, experimentation and
head-scratching to figure the DSP side of RDS reception out. I had a bit of
help from a couple of people on the [discuss-gnuradio] list as well.
The GRC is at home, I will post it to the list (or a pointe
I finished work on a C-QUAM (AM Stereo) transmitter, and now want to add
something similar to RDS, but not sure how to go about it. I am aware of
AMSS, but I like my wideband audio signal, and think that using the
subsonic frequencies could work.
Basically, I want to send maybe a call-sign, genre,

I don't know about having it inside the main codebase, but
converting it to use the CMake build system would be good, since it
didn't really understand how to place its python files into a filesystem
that uses /usr/local/lib64--so I had to move them manually.

It would be great to have the rds code inside the gnuradio tree instead of
in a separate cgran project!
; )
I don't know why, but when I tried the cgran rds code, the grc example
worked much better then the python one.

Actually, I'm using the blks2 WBFM block, which I believe is a PLL

I managed to get gr-rds built tonight, and was able to test it planted
inside my FM receiver.
Even for a local station, there are *lots* of errors, and more distant
stations get even more.
I'm going to play around a bit with filter bandwidths, etc, to see if
I can improve it.
Looking at the mod
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.
On Tue, 21 Feb
2012 12:27:54 -0500, Andrew Davis
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.

Hi Erlend,
I think you should be able to see the subcarrier with the USRP. The
injection level of the RDS signal is typically around 1.5 to 2%, this is
substantially less than the pilot, which is typically around 9%, but it
should still be visible. Make sure you have a good signal without too
