The frequency 148.600 is used by most of the MSHP vehicular repeaters (radio extender). The Highway Patrol has an agreement with the Missouri National Guard (who holds the license) to use 148.600, 148.700 and 148.800.
The Special Emergency Response Team (SERT) uses 148.700 and 148.800 for there operations in different areas of the state mostly around Kansas City.
I still hear the Division of Drug and Crime Control (DDCC) on 154.920 running surviellance operations. Also have heard the Organized Crime Drug Task Force (OCDTF) on 418.750 (low power simplex) working with DDCC on operations.
