For applications like this the rule "automessage:" was invented. What you 
could do is:

automessage: 60 1

This will run the utle command every 60 minutes. For digi_ned it appears 
to come from port 1 but that doesn't matter as the direct reply to the 
utle command is not send back on RF but only shows up on screen.

Alternatively use:

automessage: @0 1

to run the utle exactly every hour or

automessage: 1440 1

to just run it once a day.

Now you can use wget to just get two line elements in a digi_ned.tle file 
and utle will update the sattelite database when it runs.

It is a bit primitive, but it gets the job done...

Kind regards,
