Werner,
The bandwidth displayed is the audio bandwidth. A double sideband (AM)
signal with an RF or IF bandwidth of 6 kHz will contain only 3 kHz of
audio bandwidth. That is an inherent characteristic of the modulation
method, not any limitation imposed by the K3.
To obtain 6 kHz audio bandwidth for an AM signal requires a 12 kHz IF
filter - the FM filter will do that, but the firmware to support it has
not been released yet - I believe it is coming soon.
OTOH, an SSB signal can contain an audio bandwidth equal to the IF
bandwidth.

Next question: when I am in AM mode, the bandwidth shows 3.00 with FL2
enabled. With LSB it shows 6.00. btw, it sound great!
