I am aware of the supposed attenuation on the narrower filters, and have
tried testing this many times. I am unable to notice any attenuation
except very occasionally with the 300... and I also have heard (here)
that this attenuation is only a problem on Orions, not Orion II's.
In other words, I am quite happy leaving all enabled and auto-select on.
(I should mention that I also seldom use wider than 500 or 600 Hz either.)

Doesn't anyone but me just leave it on "auto" filter selection?
I use auto filter selection after I've decided which of the optional filters
I want to enable. The narrower the filter, the more insertion loss, so you
don't want to enable the narrowest filters unless you need them, such as in a
crowded CW band.
