[TrunkCom] Michigan State Police To Upgrade MPSCS TRS

[Wayne M H]

What added talkgroup capabilities? How they're announced shouldn't
have changed if that's what you're asking. A part of the APCO-25
trunking standard is a group of OSWs that are public information and I
believe can't be changed by the system manufacturer. Motorola can
develop their own OSWs, which they identify in the manufacturer
portion of the OSW, but are there mainly for their own network
support. System and network ids, along with group call announcements
should be decoded no matter what version a system upgrades to. These
things don't change, that's why they call it a standard.

The system before was 9600 and still is 9600. If the system will be
completely APCO-25 and using the trunking standard, it will use the
9600 baud rate. Btw, 4800 baud is EDACS narrowband only. Moto is 3600.

Stop worrying! Just wait for the scanner to ship and worry about it
then. It's already been tested and performed well.
