No.  If a user's "home channel" (as they are called) is busy they will be
assigned to the next open one.  If all are busy, you get a busy signal.
I'm not sure if LTR systems que additional users when all channels are
busy.  As far as I know Multi-Net systems do queing.

As far as I can tell that just akes the idiot factor out of changing
channels. If <theoretically> you have a sixth agency on a five channel
system, does that agancy share a home channel?

Then you would have to say the same thing about ANY form of trunking,
since all forms use the same principle of spreading the airtime and
non-airtime air across fewer frequencies than if you had a separate
frequency for every company.  But if you look at activity statistics then
you would see the advantage that any trunking (whether LTR or Motorola or
anything) has over conventional systems, especially in a system with
multiple users.


I don't think so, because with conventional Motorola systems,<the ones with
control channels>, you don't have agency home channels.
 I live in an area that got hit with an ice storm in '98, the county
trunking system was going nonstop for days on end, at certain times they
would tell people to stop talking in order to let the equpiment cool down.
It is a standard 800 motorola type 2 system <5 channels>. I can imagine the
mess if it had been an LTR system instead.
