Windy,

Also note that our 6-kHz 8-pole filter is targeted specifically at AM 
operation, and will provide better adjacent-channel QRM rejection than 
the FM filter, if needed. A 6-kHz filter is also required for AM 
transmit (enforced in firmware). This ensures excellent 2nd-I.F. image 
rejection.
