   We propose to observe YY Dra (= DO Dra, 3A 1148+719), a DQ Her which we
   have recently detected in archival Ginga data. The proposed observation
   would complete a high quality ASCA survey of Ginga-detected DQ Her
   stars. With so few known DQ Hers, quantifying the properties of each is
   important in advancing our understanding. By binning the spectrum into
   several different spin and orbital phase bins, we will be to study the
   different continuum components, and constrain their locations in the
   system. We will use the combination of high spectral resolution of the
   SIS, and large effective area near 7 keV in the GIS, to separate the
   multiple component Fe emission. This will help to quantify the
   characteristic temperature, and place limits on the mass of the white
   dwarf.
