re bandwidth select on am mode re K3

[Fern Rivard]

    On my K3, on ssb mode,  I can select the wide am filter position but if I go to the AM mode, the widest bandwidth shown on the display is 3 khz! Should it not go to 6 khz as I do have that filter installed and it works on the ssb and other modes except for the AM mode.  Any clarification or help with this would be greatly appreciated.
    Thanks from Fern

3kHz either side of a carrier = 6kHz

In AM, both side bands have to fit through the filter so you're audio
bandwidth is actually half of the RF bandwidth.  With SSB, since there
is only one sideband, you get audio bandwidth which is equal to the RF
bandwidth.

SSB - 6 KHz filter gives 6 KHz audio bandwidth.
AM (2 side bands) - 6 KHz filter gives 3 KHz audio bandwidth.
