They have been having horrible interference on their radio system. They will be utilizing Ops 20 when transmissions over their own radio system become unintelligible. I believe EMS has all their radio traffic on Ops 20. As far as I know fire is an as needed utilization.
This is a temporary solution until their radio system gets fixed. There is no plan I have heard of to move over to the Morris County Trunked system. It's just a temporary home, just like how Denville did the same thing when they were migrating radio systems.
