[TrunkCom] regular talk groups and private calls and configurations

[Jeff Kenyon]

Hi everyone, I am trying to monitor my ADA curb to curb service bus that 
takes me to the class that I am taking.  I have found out this morning that 
they are on the SMART transportation TRS which is a Motorola type II system, 
and from what I can gather and from what little monitoring I have done with 
this system the main talk groups are busy, but I have heard some private 
calls as well.  This morning I was talking with a driver and she said that 
the way that things are set up is that they can talk to dispatch and not 
from bus to bus, and for small buses this would be helpful, and I am 
assuming that they are using private calls, but I am wondering if there is a 
way of setting the system up so that they can use a regular talk group, but 
have it set up so that they can't talk unit to unit, but just unit to 
dispatch?  I looked through the list of talk groups I have and there are a 
lot marked as shuttle vans, and next week when I ride the bus I will take a 
long my 250D since it will monitor I-calls, but I am just wondering if there 
is a way to set up a system so that a regular talk group can be used and 
they can't talk unit to unit?
