Village of Chester Police have apparently changed unit numbers, they are now in the 72X series, as opposed to the 31X series. I'm not sure when that change was made, or why, but that is what the numbering scheme is now.
It definitley isn't internal as they were calling out to OC911 with them on both MRD and Priority channels.
The car numbers may not say anything different though, I know T/Montgomery once used 700 radio ID's, even though the cars were numbered in the 200s, and T/Chester was using the 63X and 64X series, even though the cars were numbered in the 42XX series (that has since changed)
It probably has to do with the CAD/AVL system, because the Town of Newburgh PD has been using the same numbers as the Village of Chester. Several years ago, the Village of Monroe PD changed their numbers because the Town of Cornwall had the same numbers. The previous Monroe numbers were 41x etc. Now they are 45x numbers. Before the County 911 system was around, duplicate car numbers at different agencies were not an issue, but once 911 started using the CAD & more recently the AVL system, duplicate numbers can cause confusion for dispatchers & conflict within the CAD/AVL systems when the "closest car" numbers pop up for a "polling" call.
trauma74, If I'm not mistaken the AVL system has been in place for a few months now, well prior to the v/Chester changing their identifiers. So if it was a problem as you imagine, wouldn't they have addressed it sooner (although who knows what happens at 911 sometimes...)?
-I'm agreeing with your point, just wondering why the wait and why only Chester (v/Maybrook has or has had number conflicts too)
There have been rumors about v/Chester and t/Chester merging....did the news confirm that or was it just speculation?
