Thom,
The 80 kHz or 150 kHz is the range for all bands.
For most bands, the active CW portion is within the first 80 kHz of the
lower band edge, so there is no need to be concerned about which crystal
will be used.
However, on 30 meters, if you choose to use the 18.000 MHz crystal so
you can tune to WWV at 10.000 MHz, then with the VFO tuning range of 80
kHz, you will tune from 10.000 to 10.080 kHz which is always below the
30 meter ham band (10.100 to 10.150). So if you choose the 80 kHz VFO
range, you must use the 18.100 MHz crystal so the tuning is from 10.100
to 10.180 MHz (greater than the 30 meter band high frequency).
If you choose to use the 150 kHz VFO range, you will want to use the
18.000 MHz 30 meter crystal since you can tune to WWV on the low end and
also tune the entire 30 meter ham band since the high frequency on 30
meters will be 10.150 MHz or greater.
With the 150 kHz VFO tuning range, the tuning will be a bit more
"touchy" than with the 80 kHz range because each turn on the VFO knob
covers twice the frequency variation.
The choice is yours.
Looking at it the 'other way around' - if you want to cover the 40 meter
band from 7.000 to 7.150 MHz to work those stations that work in the
old novice portion of 40 meters, then you would choose the 150 kHz
option. It does not matter much on other bands (except 30 meters)
because most CW activity is in the lower 80 kHz of the band.

Howdy All,
Started building my Elecraft K1 this evening. All is going well, so
far, with the KFL1-2 board. Just finished installing all components up
to the toroids on the 40 meter band.
I am confused about the 80 Khz or 150 Khz tuning range setting.
Is this for 30 meters only or for every band?
I installed the 15.000 Mhz crystal for 40 meters at X1. Will the tuning
range be 80 Khz or 150 khz?
The manual says the most used portion of every band for the 80 khz setting.
I am confused about how to set that on the 40 meter band.
