Remember, Close Call is primarily for on-the-scene comms. The scanner receiver is attenuated, reception range is drastically reduced. It’s intended use is primarily for the reception of activity of all the services working that incident, fire, police, EMS, etc. In some areas, regions, emergency services may use something like Connecticut uses, called “STOCS” (do a search for Ct. STOCS) where all agencies have a simplex frequency on the band they use which is received and repeated on low power. It allows each agency to cross-patch with other agencies, allowing for comms across VHF, UHF, UUHF. A “STOCS BOX consists of three radios, each on the bands listed here. It then retransmits on all three bands which allows for the ability to cross agency comms. And because it’s low power (5 watts) it only services those agencies on scene. It’s interoperability at its finest, considered a stopgap method, until full interoperability can be phased in by all agencies, which may never happen for various reasons, but I suspect the major reason is budget constraints. And I’ve heard once in place, satisfies the interoperability needs without replacing current systems, so, the issue becomes not one of a temporary need but more of a permanent solution.
