               K3 SSB Possible Filter Set XFIL option

	Some of us have physical limitations that hinder our ability to get the 
most out of the K3.

1. 	Manual dexterity and touch feeling are required to change the filter 
settings especially on SSB. This is difficult to do during a QSO as it 
is so easy to nudge the VFO knob. Positive detent encoders and 
larger/longer knobs (RIT size, parallel, not tapered) would have helped.
	It would have been easy to feel detent clicks but without them, you 
cannot tell when you have turned the knob far enough to make a change 
(have to look at display). Maybe use audio beeps when enabled?

	The “XFIL” button is not useful on SSB. Could this button be used to 
recall a number of user settable DSP bandwidths and offsets? Tap to 
recall, 3sec hold to store and 8sec hold to clear or set/assign/name 
via config.

	I myself would program something like the following:
		2.7KHz – for good band conditions
		2.1KHz – for general DX/Contesting
		1.7KHz – for normal voice in QRM/noise
		1.7KHz – for bass voice in QRM/noise

	Knob twiddling is OK for filter set-up when time is of no consequence 
but not during the heat of the battle. Button pushing can be 
accomplished quickly and no need to look at the display. Set as many or 
as few bandwidths as required. It could be a benefit on CW/Data as well 
but then would require a different set-up by mode.

	I believe this use of the XFIL button would be of benefit to all, not 
just those of us that find knob twiddling awkward.

	Then there is the big question. Are we running out of firmware memory 
yet, or is there plenty left? We need to keep Wayne busy or he might get 
bored and find something else to do!!!
