that's a pretty good idea actually.

Btw, I have tested with multiple radios, in different frequencies and the result is the same. Moreover, I've read most of the threads on the issue and there are people with similar experiences, so it's either hardware issue, software restriction, or maybe in places where the fm band is crowded the radio works much harder (but then some people have pointed out before that their n900 can overpower radio stations at close range).
