Tim,

I have never encountered a multi-band SDTS product before!  Do you have a
real need for multi-band SDTS support, or are you just trying all the assorted
data products you could find?  If you need it, I could look into implementing
it.  Please submit an enhancement request in Bugzilla.

Best regards,
