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

Robert,

As expected, the problem with your report is the unseen carriage return 
characters.
Your file uses a single \r\n sequence at each line, while the FOS patterns 
expect
\r\r\n. In particular, the start of a bulletin is requires to be SOH \r \r \n
and the end of a bulletin is required to be \r \r \n ETX. Without that correct
sequence, the decoder is just reading bytes looking for a valid bulletin.

You can modify and decode your data through a pipe such as:
cat BIWS2006111017 | sed 's/\r/\r\r/g' | dcmetr -v 4 -d - -c 061110/1700 
YYYYMMDDHH_metar.gem
