[Elecraft] K3 SSB Possible Filter Set XFIL option

[Tony Fegan VE3QF]

Hi Lyle, Joe,

	Yes I have used Norm 1 and Norm 2. It works fairly well but it's not 
easy for me as sometimes I hold on too long and usually end up with both 
set the same. Others have reported the same problem. A longer hold for 
save might help here.
	I have 13KHz (not used on SSB) , 2.7KHz, 2.1KHz, 1.8KHz and 400Hz (not 
for SSB) filters installed. The centre frequency is not positioned for 
clearest audio on the narrower filters. This means juggling with shift 
and high cut which is not easy for me. This is what I want to get away from.
	I assume that Norm 0 is the same setting as using XFIL button for 
2.7/2.8KHz and is not a problem.
	My best way of getting 3 preset filters is to use Norm 0, Norm 1 and 
Norm 2. For SSB dx working I can put a narrower Norm 1 and Norm 2 into 
I/II and switch with one push of the I/II knob. I operate the Norm 1/2 
button with the flat of my thumb and lift my arm up and down to rotate. 
Not easy but it usually works. I would like to try bigger and longer 
knobs but am not sure of the shaft size. 1, 2 or 3 taps on a button 
(XFIL) would be much easier and quicker.
	The other (and maybe easier for me) alternative is software macros 
which I have not looked into yet. I don't think any control program at 
the moment will directly set the DSP filters.

	Hope this makes sense.
