[gembud] Synoptic Data source

Hi,

I'm looking for a good source for synoptic surface data.  I've been trying
to use the files available at http://weather.admin.niu.edu/data/, but I
keep getting errors with dclsfc:

[8515] 140725/0228[LS -3]  Bad group length - reject rest of report: 521
SMMX01  MXBA    250600

Something that is in a format that's ready to be pushed through dclsfc
would be great... or already in gempak format would be even better!

Thanks,
