There's the Data / Sound / Radio / Washington / Events, and a bunch of INI files beneath. The "Events.ini" controls each of the other INI files in that folder, with the Radio.ini file in the folder 2 levels above controlling the overall behavior of the "radio channel". None of those from my first-looks have anything about a base change for you... and Messages.txt in the Campaign folder doesn't either... nor does UPCLocalization.tsr... My brain is failing me. I know it gets generated when you base is "transferred", but we'll have to wait for an expert to come along and refresh my memory as to where to look...
