Interstate 5 Talkgroup
Border to Border Regional Interstate Coverage - CA OR WA

    DRAFT

NEW:  All of I-5 covered in Washington, 2/3rd's of Oregon and Vancouver BC

     

I-5  ---  TG ID 3168 on Timeslot 1 on DCI and PNW

Interstate 5 is the only freeway in the US that is contiguous from border to border 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 2016.

 

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 at DCI and PNW.

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.

 

 

There are approximately 25-30 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. 

 

We expect by the end of 2017, we will provide coverage of all of Washington and most of Oregon. 

 

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 and PNW have 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.
