[gembud] REFD and REFC in NCEP HRRR?

With the Iowa State HRRR feed discontinued (much thanks for hosting that 
Daryl!), I have moved to using the HRRR GRIB2 files from NCEP.  After 
downloading and converting these files to .gem format using dcgrib2, I'm not 
seeing any of the reflectivity products in any of the available GRIB2 files 
(REFD and REFC).  I'm using gdinfo to view all fields - anyone else seeing the 
same?  I sent a note to NCEP and they say that those fields are there.

I'm running GEMPAK 7.1

Thanks!
