[Elecraft] K3/K3s filter setting with the K3 Utility

[Richard Ferch]

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 bandwidths, one of which
happens to be the same as or close to the bandwidth of one of your roofing
filters. You find that when that roofing filter is engaged, that particular
digital mode does not decode as well as it does with a wider filter
setting. You might find that changing the configuration to switch that
filter in at a narrower setting allows that particular mode to decode well,
without having a noticeable adverse effect on the next narrower bandwidth
mode you normally use. The likelihood of all this happening in combination
with an actual need for a tight roofing filter because of nearby very
strong signals might be quite low, but there is at least a theoretical
possibility of such a scenario. There are probably more likely situations -
just pointing out that it is not impossible that someone might want to do
this. The good thing is, the capability is there if you somehow find that
you need it.
