I just heard the Dispatcher informing units on CI-2 that it will no longer be the select mode as of today. Units using CI-2 are to ID the channel as well as their unit number when calling coms. They were instructed to use “CI-7 Mobile” full time instead of CI-2 if they have it. Begs the question, what is CI-7? I could not find a frequency or Talk Group with that designation.
