20020214: gdradr, gdplot2

Chance,

It sounds like gdradr is either:
1) not finding current radars within the 30 minutes (RADDUR) 
   previous to the RADTIM
or
2) Not finding your radar data.

When gdradr runs, it will list out to the screen the
radars it is using, or if they are too old. I might
need you to send me that output from the program.

Verify that your radar data is within 30 minutes of current, or set
RADTIM back to the time of your data.
