Manatee County Public Primary Control Channel?

I'm trying to find the exact primary control channel frequency for Manatee County Sheriff's Office operations or any police chatter. I'm using UniTrunker and an RTL2832U dongle and tuning to the listed frequency for West Bradenton at 854.73750 is not showing anything, even after fine calibration of the dongle and also viewing a waterfall in HDSDR. I'm able to pull in Sarasota County and other nearby towns but although the location of the transmitter for the West Bradenton primary control channel is about 2 miles from home I believe it's no longer correct.



Does anyone happen to know if the primary control channel was moved in the last few months or if there was a system switch?



Thanks!
