Just looked at the application, apparently they needed to file a new application, and get a new authorization letter, granted in June of this year. New license with P25 Phase 1 emissions designator granted June 11, 2020. Delay was possibly due to failure to complete tower construction on time, based on the attached Construction Reminder letter sent Feb 4th of this year. The new construction date for some of the new towers is June of 2021, so it might be next year before the change happens (see attached license).
