The two narrowest widths do not have the Rx EQ available.  What you are 
hearing is the loss of +16 dB boost when you go to the narrowest 
selectivity settings.  You can get around this by not using boost of the 
desired frequencies.

In general, the Rx EQ will not add selectivity. It is *not* an 
additional filter stage.
