Yes.  Each talkgroup in an LTR system is assigned to a repeater as its "home
repeater".  The talkgroup will always try its home repeater first.  If it is
busy then the system controller will switch it to a free repeater.  On a
slow system a talkgroup may not have to leave its home repeater very often.
Talkgroups can also be given priority status for their home repeater (such
as ambulance and security commpanies) .  They will bump other users off of
the home repeater.  If you hear these priority talkgroups you may not even
realize that it is a trunked system because they don't move anywhere.
