[GEMPAK #CSI-145319]: dcmetr and Antarctic AWS sites

Robert,

I clipped out your metar and sent it to dcmetr and it decoded:
[2273920] 061109/1104[DC 3]  Starting up. Version 5.9.4
[2273920] 061109/1104[DCMETR 7]  DCMETR version:  3.3

[2273920] 061109/1104[DC -9]  End of input data file.
[2273920] 061109/1104[DC 5]  Normal termination.

when you say nothing happened, I'm assuming that you mean you have no files 
named
YYYYMMDD_saot.gem in your surface directory? If you do, then you are probably 
just waiting for
the data to flush the write before you can see it (without any other data, the 
decoder will flush in 600 seconds by default but can be adjusted with -t).

Otherwise, you might want to do some tests by cat'ing the FILE'd bulletin to 
the decoder
so you can test things out with -v 4. You can send me one of your metar 
bulletins for me to try if you 
still have trouble.
