The Utah Communications Agency Network (UCAN) and the Utah Communications Authority (UCA) will be decommissioning the current 800Mhz Motorola trunking system by the end of 2023. UCAN is the main Public Safety trunked system used throughout the state of Utah and is one of the largest systems in the nation. Over 100 Motorola Trunking sites will be shut down and replaced with an all-digital P25 system using 700Mhz. It will impact all Utah public safety and services agencies. After the change, a large body of the information on this site will be out of date.


Your scanner or radios must support P25 digital and will need to be reprogrammed to continue to hear anything on the new system. The community isn't sure how much of the traffic will be encrypted after the switch. If regular channels are encrypted, it will become illegal to attempt to monitor that traffic. We can only hope that if the UCA chooses to do this, they will offer time-delayed or filtered streams of radio transmissions to the public. The public has a special interest in monitoring the activity and operations of public safety agencies. Recent documented abuses by law enforcement officers who have covered up activities or mistakes by abusing laws originally meant to protect victims are a prime example.

Please copy any information you want or need from this site prior to December, 2022. For additional details see the RadioReference Utah forum. An effort is underway to save some content on the RadioReference Utah wiki: https://wiki.radioreference.com/index.php/Utah_(US).
