Hi Harry,

I got the same error as you when RADPARM is left undefined, but successfully 
displayed base reflectivity, radial velocity and spectral width by defining 
RADPARM as dz, vr and sw, respectively.


GEMPAK-GPNEXR2>l
 MAP      = 1 + 5 + 3
 GAREA    = dset
 PROJ     = rad
 RADFIL   = /data/ldm/gempak/nexrad/craft/KLGX/KLGX_20111114_2147
 LATLON   =  
 PANEL    = 0
 TITLE    = 1
 TEXT     = 1
 CLEAR    = yes
 DEVICE   = xw
 LUTFIL   =  
 IMCBAR   = 1/.9
 TILT     =  
 RADPARM  = dz
 RADTIM   = current
