When I try to download the NOAA Pacific 500 mb forecasts within Expedition, I get an error message "waiting for server" but nothing downloads.  The Atlantic 500 mb forecasts are working and download very quickly.  Is this a NOAA problem or an issue with Expedition link?

Thanks, I think this was the problem.  The SoCal race had finished, so I changed to a different race in order to test the YBT functions live.  When I selected the reference boat as the last step in setting up the new race, the Tracking window populated with all the data.  But I am nearly certain I had picked a reference boat for the prior race.  Does the reference boat need to satisfy any particular criteria in order to be a "valid boat" for purposes of the tracking function?  In the current race, I experimented with changing the reference boat, and all the boats I selected seemed to work.

Thanks, Nick.  We have not used Iridium Go much to get Gribs because of speed and connection problems.  We will have to try it again.
 
One complication on our boat is the Iridium Go is NOT wired into the boat network (which relies on a 4G modem and SailorSatphone for data access).  To use the Iridium Go as a backup, we need to log in to the Iridium Go wifi network, which disconnects the laptop running Expedition from the boat network.  We not only lose real-time data while downloading data through the Iridium, but when we reconnect to the boat network, we have not been able to access data from the race prior to the disconnection – in particular, race tracking and stripchart info.
 
This actually is not just an Iridium problem.  The Expedition laptop sometimes gets disconnected from the boat network due to other problems.  When we reconnect, Stripchart data starts over from the time of reconnection, and we usually lose prior tracking data on other boats in the race.  Are we doing something wrong?  Is there a way to reconnect to the prior data recorded for that race?
 
 

Nick - I've done further testing, and I think there is a bug in the Copy function in the Marks management window.  I'm using a new installation of Exp,  I used the Copy function to copy an existing route, rename it and modify it, and set the new route as the active route.  I then saved Settings manually, and also when exiting Exp.  When Exp restarts, Exp does not show the new route as the active route. Instead, Exp shows the route that I had copied as the active route.  If I create the same modified route manually as a new route (without using the Copy function) and save it as the active route, then Exp does show the modified route as the active route when Exp restarts.  It seems like some ID tag for the route is not being updated when a new route is created using the Copy function?

I think the Copy function is very useful (saves a lot of time), so hopefully this is an easy fix.
 

Thanks, Nick.  I created empty new .XML file using Notepad and that worked.
