Re: dcwtch newbie question

Pete,

The decoders are expecting the FOS or AFOS bulletin delimeters to
identify where
a product starts/stops. Since your log output shows no bulletins read,
you
will have to add them to the bulletins before streaming them to DC text
bulletin decoders, such as the following script:

----------------- addfos.csh -------------------
#!/bin/csh -f
printf "\001\r\r\n000 \r\r\n"
cat
printf "\r\r\n\003"
----------------- end of csh script ---------------

place the 4 line script in a file called addfos.csh, and make the script
executable with "chmod a+x addfos.csh"

then pipe your data to the decoder through the above script such as:

cat  wwus30.kwns.saw.5.txt | addfos.csh | dcwtch -v 1 -d - -c 15/1800 
YYYYMMDDHH.watch

Using your text product below, you should obtain output that looks like:
|TS|070515/1755|070516/0200|275 |0|0    
    39.99   -85.82
    39.99   -88.84
    43.80   -84.50
    43.80   -81.29
