The CCDOA is another entity that utilizes the SNACC TRS belonging to Clark County. Numerous talkgroups associated with the DOA are found on it but one of them does become rather interesting during emergencies at the airport and it is TG ID 37072 Channel 7. It was cleared for emergency traffic earlier this evening when the TSA activited an alarm at one of the terminal checkpoints. It might be worth putting into a radio if you like to monitor the SNACC system.
