one or none diamonds showing in nsharp

gempak 5.8.3a

I've got only one or none diamonds representing soundings to plot
in nsharp when looking at observered $GEMDATA/upperair .gem files.
What gives?

The ldm 6.4.5 pqact.conf entry is:
DDS|IDS ^U[ABDEFGHIJKLMPQRSTXZ].... .... ([0-3][0-9])([0-2][0-9])
       PIPE    /unidata/nawips/bin/freebsd/dcuair -b 24 -n -m 16
       -d /unidata/ldm/logs/dcuair.log
       -e GEMTBL=/unidata/nawips/gempak/tables
       -s snstns.tbl
       /data/gempak/upperair/(\1:yy)(\1:mm)\1\2_upa.gem

Is there a binning issue here and/or only one sounding getting written
to the .gem file?

The just has to be a Doh! on my part somewhere, but I don't know where.

Thanks,
-Neil
