This problem is fixed in the current (7.6.0) release of the ldm-mcidas
decoder, lwtoa3.  Please update your ldm-mcidas decoders to the current
version (announced today!) by FTPing a binary distribution for your
platform from the pub/binary directory of our FTP server,
ftp.unidata.ucar.edu.  Make sure that you grab a 7.6.0 ldm-mcidas
distribution as the 7.4.0 version will exhibit the streaks that you
note above.

>Any suggestions would be GREATLY appeciated.

Let me know (address@hidden) if this does not fix your problem.
