[Dxbase] Country Prefixes

[Ed Parish K1EP]

I turned on the cluster today to search for some new band-modes.  It flagged YU/OM2RC/P as a new band-mode.  I was puzzled, as I have YU confirmed or worked many times.  Upon closer examination, DxBase said it was Federal Republic of Germany, or prefix Y (which is deleted).  So why did it not see the U of the YU?  I typed the call into the QSO field and it again came up with FRG.   Did the prefix search stop on the first letter?  Okay, so I tried this.  I typed in YA/K1EP into the QSO field, fine, prefix is YA.  I typed YI/K1EP into the QSO field, fine, prefix is YI.  Not that I was intending to go to either place soon.  But when I type YU/K1EP into the QSO field, I end up with Y.
