Command failed: string index out of range

To Reproduce

Change grid square to be less than 6 characters

Expected behavior

If the user has forgot to set the grid square or if its less than 6 characters warn with a popup in the GUI.
The modem reports if the grid square is wrong but should handle this so that there are no errors.

Either add random characters if its less than 6 characters.

This errors appears after a wrong grid has been used so i guess this is a consequence of the wrong grid.
