[Elecraft] K3 SSB Possible Filter Set XFIL option

[Brett Howard]

So..... You can't tell when you have turned the knob far enough to
make a change?  If you can't tell audibly then why do you need to turn
the knob?  The whole point of the knob is to filter out noise or other
stations other than the one which you are working.  If you can't
audibly tell when you've made enough of an adjustment there should be
no need to make an adjustment.
