[Elecraft] 6 kc filter

[Don Wilhelm]

Bruce,

The 6 kHz filter is at the IF frequency. passband
AM is a double sideband transmission which means that the audio is only 
1/2 of the IF passband width - 3kHz.

The passband displayed by the K3 is the audio passband.  A 5 kHz width 
would equate to a 10 kHz IF passband.
