Robert,

The file you sent me was 82 bytes as the attachment. There are 4 instances of 
"\r" in the file (see with od -c obs200611132000). That means that the sed 
replacement of
"\r" with "\r\r" should yeil 86 bytes of input:
[2635166] 061113/1625[DCMETR 7]  DCMETR version:  3.3
[2635166] 061113/1625[DC 2]  read 86/102399 bytes strt 0 newstrt 86
[2635166] 061113/1625[DC 2]  read 0/102314 bytes strt 86 newstrt 86
[2635166] 061113/1625[DC -9]  End of input data file.
[2635166] 061113/1625[DC 5]  Normal termination.
[2635166] 061113/1625[DC 2]  Number of bulletins read and processed: 1
[2635166] 061113/1625[DC 6]  Shutting down.

I see 86 bytes of input.

You show only 82 and 83 bytes of input in the 2 sets of log messages
you sent me which just doesn't match the file you sent me earlier. 
An "od -c" of the file you sent me piped to that sed command looks like:
% cat obs200611132000 | sed 's/\r/\r\r/g' | od -c
0000000 001  \r  \r  \n   9   2   1  \r  \r  \n   S   A   A   A   1   0
0000020       S   S   C   C       1   3   2   0   0   0  \r  \r  \n   M
0000040   E   T   A   R       B   I   W   S       1   3   2   0   0   0
0000060   Z       A   U   T   O       1   9   0   4   3   G   5   1   K
0000100   T       M   1   2   /   M   2   2       R   M   K       A   0
0000120   1   =  \r  \r  \n 003


Verify that you have that identical input.
