[Elecraft] K3 AM operation with "FM" roofing filter?

[ab2tc]

Hi,

I am still confused as to whether I can *receive* AM with the FM roofing
filter with the *current* firmware. Can someone please give me an
authoritative answer on this? I have just received the FM filter and the
included note seems to imply that I have to wait for an firmware update. I
am not asking whether I can get more than 3kHz audio BW on AM with but just
simply if it will work?
