I heard the Southern Indiana TMC (Traffic Mangement Center) on talkgroup 28784 in Indianapolis. Indianapolis 52 TMC Traffic Mangement Center was talking to 8501. 8501 Hoosier Helper was advising Indianapolis TMC that he was 10-7 in Clarksville off of I-65. Now 52 TMC can dispatch for Southern Indiana TMC Center. Also on talkgroup 28784 I was also hearing the Indianapolis 52 TMC Units. Sounds like 52 TMC Had the channels patched.
