[Elecraft] An FM Filter working for AM or ??

[Doug Hensley]

Can someone unravel this for me?   IF the FM filter works for AM, does the AM filter work for FM ?  If not, why not ?  Elecraft says:

** AM and FM bandwidth filters are required on the main K3 TX/RX board for TX in AM and FM modes. (Only one AM filter is required for AM TX/RX, and one FM filter for FM TX/RX.) All filters can be used for RX in any mode.

So,, just what do those of us new to the K3 line need to know when choosing an AM filter ?  Are they saying "Pick your transmit mode and don't worry about the receive mode?"

/The FM filter will work for both AM and FM.  That's what I chose.  Also, I
