Pre/post script format

I’m trying to run a shell script before and after the observations to shut down an APRS transmitter that will interfere with reception. Below is how I’ve configured them but they don’t seem to work. Is my syntax incorrect? What else should I do to enable them?

Not sure that the image below will show the configuration so I’m simply entering the script name into the field.


Try providing the full path, and make sure the script is executable, or start it from the shell. For example, I use:

sh $HOME/software/scripts/ {{SCRIPT_NAME}} {{ID}} {{FREQ}} {{TLE}} {{TIMESTAMP}} {{BAUD}}
