Why do you say that no other data is being received?  According to 
    
http://www.unidata.ucar.edu/software/idd/rtstats/siteindex.php?squall.ias.sdsmt.edu
the LDM on Squall is receiving feedtypes HDS, IDS|DDPLUS, NNEXRAD, and
UNIWISC.

There's nothing wrong with the REQUEST entries in your 
configuration file:
    request HDS "^[YZ].[Q].*/mNGM" papagayo.unl.edu
    request HDS "^Y.[AQ]... KWBC.*/m(AVN|SSI_AVN|GFS|SSI_GFS)" papagayo.unl.edu
    request HDS "^[YZ].[RQU].*/m(ETA|NAM)" papagayo.unl.edu
    request HDS "^Y.[AI]... KWBH" papagayo.unl.edu
    request HDS "^[YZ].Q.*/mRUC" papagayo.unl.edu
    request MCIDAS "^pnga2area Q[01]" papagayo.unl.edu
    request NNEXRAD "/p...(UDX|ABR|FSD|RIW|LNX)" rainbow.al.noaa.gov
    request NLDN "^.*" striker.atmos.albany.edu
    REQUEST IDS|DDPLUS     .*  uni0.ucar.edu
    REQUEST NNEXRAD        .*  uni0.ucar.edu
However, I think they would be better rewritten as
    REQUEST HDS "^[YZ].Q.*/m(NGM|RUC)" papagayo.unl.edu
    REQUEST HDS "^Y.[AQ]... KWBC.*/m(AVN|SSI_AVN|GFS|SSI_GFS)" papagayo.unl.edu
    REQUEST HDS "^[YZ].[RQU].*/m(ETA|NAM)" papagayo.unl.edu
    REQUEST HDS "^Y.[AI]... KWBH" papagayo.unl.edu
    REQUEST MCIDAS "^pnga2area Q[01]" papagayo.unl.edu
    REQUEST NNEXRAD "/p...(UDX|ABR|FSD|RIW|LNX)" rainbow.al.noaa.gov
    REQUEST NNEXRAD .*  uni0.ucar.edu
    REQUEST NLDN .* striker.atmos.albany.edu
    REQUEST IDS|DDPLUS .*  uni0.ucar.edu
