The FM Tuner appears to be very sensitive to noise and static compared to the original firmware radio.

Apart from the static and noise the Rockbox FM Tuner sounds much clearer and sharper than the original firmware, so I wonder if this may be related to the OF using a lower sampling rate or cutting off the higher frequencies to reduce noise.
This task depends upon

This maybe linked with  FS#11878  I have a sansa e200, two or three actually, and will run some tests.

On both of my Sandisk MP3 players, the default FM tuner is actually a lot better than Rockbox's, or so it seems so, especially when picking up weak stations. Rockbox seems to automatically lower down the volume on weak stations, and make the quality less pleasing in doing so.
