They filed a CP a few years ago for "mode" change and a slightly different GPS coordinate location of the TX.

I know they have been trying to find an FM for a while. God Squad has that locked up well in this city. There have been rumbles WGN wants to get out of the city. Not confirmed if that is legit or not. The digital licensing and ID requirements are a moot point especially for AM stations. So that is not it.

Looks like they cancelled the app for the mode change. Don't be surprised if attachments don't show up at a later date as it was lodged today.
