Hello Dave: The errata with the list of features is the one you should have received with the Owner's manual. The current one on the Elecraft web site is C1-1 dated Nov 18.
http://www.elecraft.com/manual/K3%20owner's%20man%20errata%20C1-1.pdf It sounds like you were looking at the errata sheet for the Kit assembly manual. I have a 6 kHz filter as well, and for best audio fidelity I use a SSB mode to listen to broadcast AM. The excellent stability and high tuning accuracy of the K3 means I just punch in the frequency I want and even music is within one or two Hz of the right frequency - much too close for me to hear any tone error. As Lyle noted, the I.F. bandwidth of an AM signal is *twice* the audio bandwidth since there are two sidebands that must fit through the 6 kHz filter bandpass on an AM signal. I find that's FB on Ham AM signals, but those commercial AM stations who make full use of their 5 kHz audio bandwidth are cut off at about 3 kHz in AM mode. Gong to SSB mode with the 6 KHz filter allows the full audio bandwidth through.
