Oops. Forgot to fix that. Leaving the radio on is intentional, but it
should turn off when playing an MP3.

I can tune it much finer than that. What resolution would be acceptable?
It should'nt be tedious to tune by hand.

This is a little complicated, since I can't really measure the signal
strength in a good fashion. But sure, we can give it a try.

No can do. The RDS chip is not mounted on the FM recorder. There is a
socket for this, but it is empty. Even if we had it mounted, it would
put a huge strain on the CPU. I guess that's why they never shipped it

Ah, of course.
