Hello Bry,
 
Don't have my KWM-1 manual handy right now, but I'm sure the  info on 
crystal type is in it (I looked it up and ordered the crystals for 12  and 17 
meters some 20+ years ago).   Yes, the crystal holder is a  HC-6 style, just 
like the S Line.   The only glitch in putting the  KWM-1 on 17 meters is the 
fact that the VFO only covers 100 KHz per band segment  (plus a few extra KHz 
on either end of the band).   This means  that if U want to cover the whole 
17 meter allocation in one tuning range  (18.068 to 18.168 MHz) the readout 
will be cumbersome.   One solution  would be to cover the "band" with two 
crystals, and then U won't have to  remember the "odd" KHz error (for example 
18.0 to 18.1, and 18.1 to 18.2  MHz)........fortunately, you can easily do 
this without giving up more  existing "bands" by simply unplugging the 
crystal holder and swapping out the  two "new" crystals.   The other way to 
handle things is to  order one crystal so that the radio will cover exactly 
18.068 to 18.168 MHz  with the VFO reading 0-100 as it does on the "stock" 3 
bands........but then U  will have to make a simple correction chart to track 
the radio's actual  frequency.
