As far as I know, everyone in SL County are on UCAN except Murray PD.
Of course SLC PD and Fire are on their own system (ac33) with Dispatch Talkgroups patched to UCAN. The main SL Co Sheriff's trunked system was integrated into UCAN earlier this year, their Big & Little Cottonwod Canyon IR sites are still intact but now have UCAN system Id (7202) instead of their old 643e system Id. Parley's IR site combined the old UCAN 3 channel system with the old Sheriff's 3 channel system and is now a 6 channel system, also with a 7202 system ID.
SLC PD & Fire's old 10 channel system is now two separate systems, one 6 channel site (ac33 site 1) and one 4 channel site (ac33 site 2) systems. Data channels for site 1 are: 860.1625 (main) and 867.2500 (alt). Site 2: 866.6000 (main) and 866.8500 (alt).
American Fork PD and Pleasant Grove PD are showing up on UCAN, I believe this is finally a full transition to UCAN for those two departments. Perhaps Brett Miller could expound on that.
