First - make sure you have set yourself up for Internet uploads. See the section below if you haven't

1: Click on "Control Panel"  and choose Internet & File Uploads. Check that the "Main Internet Switch" is on. If not, then switch it on by clicking on it.
2: Click on "Setup Page #2" - find the line that says clientraw.txt. (File #28). Click on Set
3a: A new window opens up. Click on "Update Every Minute", and then Click "Save Now", or alternatively...
3b: A new window opens up. Click on one of the update period buttons, hourly, 5 mins, 10 mins etc. depending on how frequently you want to update your file (5 mins max is recommended). A list of times will appear in the window. Click "Save Now"
4: Click on the "Show file upload times". Again, choose your upload frequency. 5 mins or less is recommended. Click "Save Now"
5: Click OK and the window will close

6: Check that the two "Lights" back on the Advanced internet settings are green. If you have your ftp servers setup okay, you are good to go

If you need to configure your FTP server, you can do this in a number of places
(a) The best place to start is under Control Panel, FTP & Connections METAR NOAA, click on the connections tab. About 1/3 of the way down put in your main FTP host settings, alternatively

(b) Again under advanced internet settings  (Under  Internet & File Uploads, where you were before), click on the Other FTP servers setup. You can add ftp server settings in here - so maybe you want to upload to more than one server - or a specific server that's not your default server.

Post below if you have any problems
