Hi Buck,
This information didn't make it to the rev C manual. It will be in the
next revision:

Narrow DSP Filter Types
For bandwidth settings of 100 Hz or lower, the K3’s DSP normally uses a
type of filter that minimizes ringing: the Finite Impulse Response or
FIR filter.
If you don’t mind a small amount of ringing, you can select Infinite
Impulse Response or IIR filters for these bandwidths, which have
steeper skirts. Locate the CONFIG:FLx BW menu entry, then tap 7 until
you see IIR ON. Both main and sub receivers will use the same setting.

bandwidths. They have slightly more ringing than the default FIR
filters.)
Can you explain more about this. I don't see a reference to IIR DSP
FILTER
in the manual. And, why would I want to chose a filter with slightly
more
ringing?
