Re: 20060323: Radar Level II question

David,

there is a failsafe that if no other location can be found, it just uses
FTG so that it has something...which is what you are seeing, but this
shouldn't be happening. I get the correct display over NY here.

The NEXRII template is in $GEMTBL/config/datatype.tbl and the
file template is there which matches what you used, but
it could be that your $GEMTBL is not pointing to the correct release,
or didn't source the Gemenviron for the new version?

The garbage seems like more of a symptom of a prpogram connecting to
a gplt or device driver from an older version. Make sure you have
shut down your old gplts (either gpend or "cleanup -c").

Check your $PATH variable and make sure the 5.7.2p2 executables aren't
in that path. The Gemenviron will add $NAWIPS/os/linux/bin to your
path for the 5.9.1 version.
