During the day on Monday they used UCA Event 11 and Event 16.
Event 11 was for Local LE and Event 16 was for UHP cars and Motor's clearing the road.
I am sure there were other frequencies used but I have found nothing about them yet.
Tuesday they are in Box Elder County and I am noticed the UHP is on Event 16 again. Haven't notice anything on Event 11 but I would expect that is there plan.
