Kelly,

from the above decoder line, your KOKX data will be found under
$RAD/craft/KOKX

The RAD variable is set in $NAWIPS/Gemenviron, and is used in the NEXRII 
template
in $GEMTBL/config/datatype.tbl.

Using that NEXRII template, I am able to produce a NEXR2RHI plot from KOKX this 
morning
such as:
 CXSTNS   = 40.9;-73.2>37.4;-71.9
 GVCORD   = hght
 PTYPE    = lin
 YAXIS    = 0/20000
 CINT     = 0
 SCALE    = 0
 LINE     =  
 BORDER   = 1
 SKIP     = 0
 TITLE    = 1/-1
 CLEAR    = y
 DEVICE   = xw
 TEXT     = .8
 PANEL    = 0
 CLRBAR   = 0
 CONTUR   = 3/3
 FINT     = 4/0
 FLINE    = 0;30-7
 CTYPE    = f
 RADFIL   = NEXRII|KOKX
 RADPARM  = dz
 RADTIM   = last
 INTERP   = y
