Tonight at about 2:10 SLC PD Pioneer TG started to get a major static interruption. Sounded like a open mic but just static and scratching. After about 3 mins they moved everyone on to SLC PD Tac 1. Sounded like maybe a radio that had ether gone off the wall, or someone may have gotten onto the system causing havoc. By chance were any of you Trunk Tracking the AC33 System from about 0145-0230 would be interesting if mabe we can solve this one.
