AM 6K filter

[Philippe Trottet]

Dears,
Just installed the 6K filter and used the K3 utility.
Can hear the difference on AM mode but, when pressed on XFIL it indicates normally 6.00 but if using the width knob, it indicate maximum 5.00 at the edge.
I missed something in the configuration ?
Your advises are welcome

Phillippe,

The K3 width display indicates the audio bandwidth rather than the IF
bandwidth.  An AM signal has two sidebands that must be demodulated,  so
a  6 khZ IF bandwidth results in a 3 kHz audio bandwidth.
