[Elecraft] K3 #656 alive

[Don Wilhelm]

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.

73,
