Yes, because that's all you can read from /dev/radioX.

Unfortunately, rdsd (and all the other RDS userspace software) is somehow
unmaintained ATM. I haven't got the time anymore, and there are not many
_active_ developers to take over the project. One serious problem is that
I wrote it in C++ (I wouldn't do it again).

Anyway, if you're really interested, I'll happily give you full write access
to the repository. The project is about to die without active developers.

If there's anyone out there who would like to take over maintainership of the
RDS userspace stuff, please let me know.

I could help with docs, too.
