Rich,
Interesting food for thought. I just
received my 1.8 for the sub RX and was
wondering what others found most helpful
seeing as there are the options to custom
tailor the settings. At the same time, I
really make great use of the narrow filter
on CW and am always looking for something

Since we are on this topic. I have a question regarding the 500hz
filter. From what I have read it is rated at 525hz. So would it be
best configured to come on at 500hz or should I set it to 550hz. I do
not think you can set it to 525hz
Thanks in advance

Earlier I gave an example of a situation where you might choose to enable a
roofing filter at a bandwidth wider than the bandwidth marked on the
filter. I also gave a poor example of enabling a filter at a narrower
bandwidth. Here is a better one:
You use a variety of digital modes with different
I muffed the last part of my previous message, didn't I? Still, there are
some higher-order effects that might push someone into configuring a
roofing filter ti switch in at a slightly narrower setting than you might
at first expect.

There can be reasons to configure a roofing filter differently from its
nominal bandwidth.
For example, I have a "250 Hz" filter. According to the filter plots on the
Elecraft web site, the 6 dB bandwidth of this filter is actually closer to
375 Hz. I configured my filter to switch in at 350 Hz,
It seems as intuitive, the filter you use
is the value you select in the K3 utility
under filter configuration. I.e. a 1.8
filter is set at 1.8 in the utility.
Considering there is DSP simultaneously
occurring at the same time;
Is there any advantage to setting the 1.8
above, say as 2. in
