K3 I / II Switch

[Larry P. Greenberg]

I understand that the I / II switch on the K3 switches the last two used DSP filter settings and crystal filter selections.  I am having a little trouble understanding how this switch is useful.  Could someone explain its practical application?  Most of my operating is chasing DX and contesting.

I have mine set up fairly spartan, I think.
I   is  700 Hz on CW, 2.7 KHz on SSB and 1.0 KHz on Data
II  is  400 Hz, 2.6 KHz, and 1.0 Khz on the same settings.
I guess going between the two is a lot easier or quicker than turning the
Bandwidth knob.

They used to get a lot of use (actually #I did) when I would be chasing DX
spots, or typing frequencies, from the logging program because when I'd
change band and/or mode several times the K3 would forget what the filter
setting was supposed to be for the mode.

I would rather have them both the same for the DSP filters and have them
store the power level - 100 watts for barefoot and 70 watts for driving the
amp.    Although I could leave the K3 set at 70 watts all the time - if I
can't work them at 70 watts I very seriously doubt that I'm going to work
them at 100 watts!

Now I have the logging program telling the K3 what to set the DSP filter to
for the given mode from the logging program band plan, so I don't know if
the band/mode default was ever fixed!
