K3 CW Filter Tip

[N4BP]

I have the 400 cycle 8 pole optional filter and was disappointed with
the latest firmware to see NR disabled below 500 cycle width settings.
My filter is in the "FL2" position, so I went into the configuration and
changed "FL2 BW" to 0.50.  Now the 400 cycle roofing filter switches in
at 500 cycles width setting and noise reduction remains on.  The NR is
truly amazing even at this narrow setting!

Bob,

The firmware revision we're now testing allows noise reduction at all
CW filter bandwidths. Sorry for the temporary inconvenience.
