Got that, but my inquiry is what does the "targets" preset mean.  I only see targets in the AIS section of commands; is that the required check?

You need more than one to see a track. The boat positions will be interpolated to the display time.

​Also, if you deselect a boat to be drawn, it won't

They do have a date part, but Windows doesn't display that for the null time. Maybe I should get Exp to set it to be blank to start with.

​Eg, try settings a start timer, then click the 'set all start times to gun' button.

thanks - that worked
 

You can use XGate between Exp and the Iridium Go, but I suspect something like the Sailmail Airmail app might be the best option.

Someone else might be able to comment.
