Motorola designed "All Call"
to be a supervisory talk group. "All Call"
is heard by ALL Talkgroups on the Time Slot. These unique
properties over-ride all efforts for selective listening
capabilities programmed into other user's modes
(channels). "All Call" over-rides the settings
of "Rx Groups" to provide selective monitoring of
other Talkgroups. An analogy would be making every
channel a "Priority" channel in a cheap police scanner,
simulcasting 100% of the time on all Talkgroups or as if
one turned PL decode off in a receiver and then
listening to "carrier squelch" on a community repeater
with a tone panel. "All Call" is the only
Talkgroup that enables a user to over-ride all
user's radios selective settings on a repeater or IPSC
network. It was designed to be much like field
supervisor's channel to all the troops, which is
certainly not to be routine or constant.
For these reasons and for slightly
better network security, the "Comm" talkgroups
were created as a replacement for "All Call".
So, "Comm 1" (TG ID #03777215) has replaced "All Call" on
Time Slot 1 and "Comm 2" has replaced "All
Call" on Time Slot 2. "All Call" is
NEVER to be used on
Time Slot 2. To be clear "Comm 1" and "Comm
2" are two distinct
talkgroups and are only to be used on their matching
Time Slots. There are benefits to having these
talkgroup "pairs" and we have several "pairs" authorized
for network use on both Time Slots.
Currently, "Comm 1" is the
standard entry point into the TRBO-6 Network. This
means that the "Comm 1" talk group is used on
time slot 1 (only) for all normal communications on our
main networked "channel" or "mode".
"All Call" should
NOT be used on Time
Slot 1. If your local repeater has IPSC enabled on
Time Slot 2, then again, do not use "All Call"
on Time Slot 2 either. See:
Repeater List to learn if your local repeater has
network traffic on Time Slot 2. Only a few repeaters have IPSC enabled on Time Slot 2.
Some local owners may allow the use of "All Call"
if they have a local only Time Slot 2. You should
check with the local owner first before using "All
Call."
If you do not have "Comm"
talkgroups in your radio, then "All Call" is
permitted for now only on Time Slot 1 but
PLEASE make an effort
to have "Comm 1" and/or "Comm 2" added to
your radio. More details are available in the
member area,
including the latest
User's Codeplug
that has the complete setup for the network, less your
local freq and color code.
