[Elecraft] Adjusting Filters (K3 newbie)

[Brian Short]

 I am confused about the filters and the bandwidth display...

I get a display that has 2 bars on far left and right.

The Bandwidth widens and narrows the bars in the middle, 
but the bars stay at the edges? Like this:

|   ||||||   |

narrows to

|     ||     |

but, why not

     ||     

or

    |||||   

only?

I have 1kHz, 500Hz, and 200Hz filters.

I am making QSOs etc, but seems strange.

Confused?
