1. You are playing EVE, and as mentioned in the Update in
this post, broadcasting is disabled by default for EVE. You can re-enable broadcasting at your own risk. To do so, select your character set in the top left, and untick the option 'Disable capabilities to control multiple windows simultaneously, including Broadcasting and Action Target Groups (EVE Online)'
2. The actions in your Activate Repeat mapped key don't make sense to me. The Target field for the first two actions in Step 1, are normally set to Window:Current, i.e. you want the current window to activate broadcasting. They way you have it configured means that all other windows, except the current window, will activate broadcasting, so you will never get broadcasting from the current window, unless you turn it on, and then switch to one of the other windows where you have just activated it.
