-### How Trunking Works
+## How Trunking Works
 For those not familiar, trunking systems allow a large number of user groups to share a limited number of radio frequencies by temporarily, dynamically assigning radio frequencies to talkgroups (channels) on-demand. It is understood that most user groups actually use the radio very sporadically and don't need a dedicated frequency. 
 
 Most trunking system types (such as SmartNet and P25) set aside one of the radio frequencies as a "control channel" that manages and broadcasts radio frequency assignments. When someone presses the Push to Talk button on their radio, the radio sends a message to the system which then assigns a voice frequency and broadcasts a Channel Grant message about it on the control channel. This lets the radio know what frequency to transmit on and tells other radios set to the same talkgroup to listen.
