I-5 --- TG ID
3168 on Timeslot 1
Interstate 5 is the
only freeway in the US that is contiguous from border to
border or coast to coast in the United states. The
goal with this talkgroup is to be able to have
continuous (or nearly so) coverage from our northern and
southern borders with Canada and Mexico (Wiki).
Including our current coverages into Baja Mexico and
British Columbia, that would be approximately 2400
miles. While unlikely that complete coverage will
ever be attained, the major population areas could be.
Currently, our coverages are approximately 508 miles
with another 243 miles to be added based on new
repeaters being planned for Oregon and Washington in
All repeaters have
I-5 on full time. Please limit the general chatter
so that our repeater owners will not be pressured to
change to PTT. Any change to PTT will dilute the
value of this travelers talkgroup. 3-5 minute
hold-off timers are in place generally.
increasing use and arguable success of the I-5 talkgroup
has spawned a new talkgroup: PNW 2 (103187 on TS 2) to
augment I-5. PNW 2 is also full time but on TS2
and is a general chatter talkgroup, implemented in
part to reduce the chatter on I-5 which occupies PNW's
main or priority timeslot. PNW 2 is open to any
c-Bridge that wishes to carry it, without the
restrictions imposed on I-5.
The Interstate 5
talkgroup has been created specifically for use by those
who travel Interstate 5 anywhere from Canada to Mexico
or have an interest in TRBO communications up and down
this freeway corridor. It should, in essence, be
considered a "phone home" talkgroup for travelers moving
along this 1,400 mile stretch of North America with RF
coverage that spans 3 countries. More on the
"phone home" concept in the
iCall talkgroup page.
approximately 20-25 TRBO repeaters that have likely
Interstate 5 coverage in California, Oregon and
Washington as well of much of British Columbia (Hwy 1
and 99) . San Diego (Otay Mtn) has coverage well
into Baja California as well. By the end of 2016,
we expect to have 13 repeaters carrying this talkgroup
sans any existing repeaters that choose to join
randomly. We expect his should provide coverage of
all of Washington and most of Oregon by years end.
California growth has increased with the participation
by Mountain West in January of 2016.
USE of I-5:
By design, I-5 is to be kept on full time on the
repeaters that carry it. As DCI has I-5 on
timeslot 1, it is considered a priority talkgroup on our
c-Bridge. This is important as it is always
problematic when users try to use it as a timeslot 1 gab
channel. It is specifically for the I-5 travel
corridor and of little use if the talkgroup evolves to
PTT access as repeater owners tire of its misuse.
It is considered a calling talkgroup and limited talk
and then when no other TG is convenient. If
allowed to be another wide area talkgroup, repeater
owners are going to press for changes to PTT and that
will reduce its value to its users overall.
c-Bridges carrying I-5 are encouraged if not expected to
have the 3 common statewides and TAC's in place to
afford I-5 users options elsewhere for longer chats.
Repeaters without I-5 corridor coverage should not have
access to this I-5 talkgroup as a general policy.
If your repeater or
c-Bridge would like to join this special purpose
interstate TG and agree in concept to the use outlined
above, please contact us at
DCI for more information.
