[LDM #VLH-822247]: TDWR Product

Hi Warren,

Sorry for the slow response...

To confirm, you did stop your LDM, delete and remake its queue, and restart,

OK, thanks.

Thanks, this was very useful in narrowing down where the problem is likely to 

I extracted the file you sent and accessed it in McIDAS-X with no problems.
This tells me that there is likely nothing wrong with the file and so with
the LDM writing the file.  This leaves GEMPAK as the likely culprit.  I will
talk to our GEMPAK guru, Michael James, to see if he has any problems using
the file in GEMPAK.

The test I just ran strongly suggests that there is nothing wrong with
your LDM, so I would concentrate on GEMPAK.

> Or perhaps that LDM is working perfectly and consider this a GEMPAK issue?

Yes.  Again, I will get Michael to take a look at the TV0 image you sent
to see if our installed version of GEMPAK has any problems.

More later...
