• Answer:

  Trunking is a system which multiple agencies are sharing the same system. One individual department conversation jump from one frequency to another. Conversations of individual group/department can be followed by programming a talk group. Most system there is one frequency called a Control Channel, this channel sounds like a buzz-saw if monitored conventional. The Control Channel is the brain of the system, assigning each user on the system a frequency when transmitting.
