This is what the campaign radio messages will look like for those not using my UIs mod or MO (sound will be heard also of radioman saying new radio message received):
This is campaign radio messages only (regular radio messages will not work).
Those using my UIs mod or MO will receive the campaign radio messages (and regular radio messages) via the Radio messages box.
I should be releasing this tomorrow. The release will include all necessary files for this to work on stock game. Those who would like to incorporate into their mods may do so. You will have to add everything from the mod and edit your Page layout.py file to include all changes I made.
This is to be used with Trevally's campaign radio messages at post #1 of this thread for those not using my UIs mod or MO so they can receive the campaign radio messages.
