RDS blocks

Hello, I’ve started playing around with the RDS blocks and examples, but
I
found that the blocks do not compile as taken from the tgz that was
posted
on the list some time ago. In order to make them compile, I had to move
them in the how-to-write-a-block environment.

This done, I have been able to successfully see RDS information, even
though I am not completely aware of the meaning of what is shown on
standard output.

In the distribution there are also some blocks, like a frequency divider
and a byphase demod; now my question is : is there any particular reason
for having dedicated blocks or is it possible to think to use standard
gnuradio blocks in order to frequency divide and psk demodulate?

Also, is there anyone aware of any reference with detailed information
on
the error correction bits at the end of the blocks and how to use them?
I
haven’t been able to find the standard anywhere, and I have the strong
suspect it’s not going to be available for free. Some detail is
available
here and there, but I could not find any detail about error correction
bits.

You can find the information you are looking for in a book called “RDS:
The
Radio Data System”, it is the book referenced by the RDS webpage. I got
hold
of it through my university library…

how can you compile rds blocks? I really need help

Here is a link to the full RDS stanard.

Hopefully that is the system you are trying to decode.
