If you expect to receive AM as AM you will need either the 6 KHz
(AM) filter or 13 KHz (FM) filter.  You can receive BCB AM using
the stock 2.7 or 2.8 KHz filter but you must receive the AM signal
as if it was USB or LSB and zero beat the carrier.  Doing so will
give you significantly restricted frequency response - barely good
enough for "Talk Radio".
