[Elecraft] 6 KHZ FILTER

[Joe Subich, W4TV]

The 6KHz (or 13 KHz FM) filter will do an indicated 4 KHz width
with 2200 Hz center for a bandpass of 200-4200 Hz.  I do it all
the time.

The reason I do not use 2000 Hz center is that the K3/K3S DSP
rolls off at 200 Hz (there is an option to set the LF response
lower but I prefer the 200 Hz cut off for SSB otherwise).
