[Elecraft] K4 on AM

[Grant Youngman]

An audio response of 4-5 KHz isn’t unreasonable.  A maximum around 6 KHz would be better, and since it will be adjustable, the response (with relatively steep rolloff) can be tailored to be compatible with band conditions and occupancy as necessary.

I know this is a sensitive, if not plain explosive, topic in some circles — but most AM users do manage their bandwidth with common sense, and to be considerate of the rest of the community.
