The PL-880 is a fine portable receiver, but does not meet the agreed-upon definition for an Ultralight radio. Two matters in particular where it "transgresses" are the overall cubic inches of the case dimensions, and the extra modes like SSB and CW.
You can read about the Ultralight requirements in the "ULR Definitions" PDF that is found in the "General Information" folder in the Files section of this Yahoo Group.
