Last week I noticed that radio service was in the county fixing some of the problems as far as remote siren controls and quality and volume of voice communications....The next day I noticed no traffic during the day shift, but it returned at shift change. I suspect that they were toying with the new system after hearing what I heard last night.....I heard an officer ask what I believe to a county officer if he could switch over to Davis digital frequency. After about 5 minutes radio traffic returned to the normal frequencies....It is my guess that Davis and Murray county are digitally capable....I also noticed during the last few days that the different departments ( PD, Fire, and EMS) were having difficulty communcating with eachother while responding to various traffic problems due to the weather.....I checked the database last evening and saw no changes......Just a heads up to anyone interested.
