Yes. Be sure to enable all relevant crystal filters; they'll be 
selected automatically as you rotate the WIDTH control. The 6 kHz 
filter will give you the best combination of fidelity and 
adjacent-channel rejection. You can go down to 2.8 or 2.7 kHz, if you 
like, although that will severely constrain the audio bandwidth (to 
about 1.4 kHz).
