King George has made some tone changes for sheriff/fire.
Sheriff
159.0900 [146.2] Dispatch
Fire
151.1150 [141.3] New primary dispatch?
155.7600 [141.3] Old primary dispatch; unknown new use
His post was made about 3 weeks ago, however, it seems that it's been determined that since that time, that the Fire/Rescue dispatch has remained on 155.760. I'm too far away to verify, but I am sure that David can add some info for us when he sees this thread.
I also see that a bunch of 173MHz freq's are licensed to King George County, related to public safety. Anyone know what these might be used for?
