Bring your own Repeater

 

Are you interested in bringing your own repeater (BYOR) to the PNW DMR network?  Do you have a site, a repeater or only part of what is needed to deploy and need help getting to the finish line?

Well here is how it's done, what we need from you and what we can do for you as well as a bunch of other stuff in our effort to grow DMR in the Pacific Northwest. More on the technical side.

 

So what you need?

  • A repeater; Motorola MotoTRBO, any model VHF or UHF, capable of IPSC networking, almost all are.

  • A site in our region; wide area or fill-in sites wonderful but garage locations are possible.

  • Internet connection, dynamic IP, slow speed is fine, 30khz bandwidth is miniscule but must support UDP port inbound to your repeater.

  • RF system to support a repeater; typically a duplexer, isolator, quality feedline and quality antenna, much depends on your site requirements.  Similar to any FM repeater installation but with an Internet connection.

  • A frequency pair in the 2 meter or 70 cm Ham band suitable for your site.

  • A Radio ID (issued by DMR-MARC).

  • Your ability to put it all together and deploy your hardware.

    • If you need help with some aspects of parts to deploy, ask us if we can with equipment.

What we can provide you:

  • All IPSC networking and backend support to put your repeater onto the PNW DMR network

    • In some cases, a collaborative effort where PNW DMR will supply all or part of the indoor hardware such as:

      • DMR repeater when replacing an existing repeater

      • DMR repeater, duplexer, isolator and polyphaser/local group provides site, Heliax, antenna and Internet

  • A deck of talkgroups, much your choice but also with several required.

    • Your choice of talkgroup setting to suit, again with certain requirements

    • May try the open network if you wish to test or provisionally join PNW DMR

  • PNW DMR Web support for your repeater (see our website generally)

  • A c-Bridge account to help your admins monitor your repeater...and the rest of the network

Other considerations:

  • We require that your repeater be "open" and welcoming to visitors and travelers.  A closed repeater does not align with PNW DMR's goals.

  • Your repeater and it's users must conform to the commonly accepted DMR radio settings to keep the maximum compatibility possible for the smoothest trouble-free network operation. (no ARS services, use TXI if available, never use TX always, etc)

  • Your user's TX audio levels must be maintained at typical levels; very low or high audio is hard on the listening audience.

  • All user radios must have valid (DMR-MARC issued) Radio ID's and assigned to that user.  Do not use default 1 nor use someone else's Radio ID.

  • PNW supports EMCOMM and public service events and places priority there

    • Special talkgroups are available for local and statewide exclusive use for EMCOMM and other non-emergency training or public service events.

  • Do not use active GPS services, Private Call nor Encryption

  • Basically, be a good Ham neighbor.

  • Please no politics or religious discussions over the air.

Our resources:

  • PNW Website; chock full of everything about MotoTRBO/c-Bridge networks

  • Resources for your users via the web

  • Yahoo Group support

  • Codeplugs for many different DMR radios that cover the DMR repeaters in our region

 We can help with Internet settings, router UDP pin-holing (port-forwarding), ISPC settings, Talkgroups, codeplugs and user/system management.  If you have your repeater already, we suggest you get it on the IPSC network sooner than later, let it burn-in, be sure that the IPSC networking is correct.  When you do make your way to your mountain-top, you will know that your ISCP networking is fine so if you have any issues getting onto the PNW network, you will know that your local Internet connection is the choke point.

We will provide you with the master IP, master UDP port and the network authorization key.  We publish all our information otherwise on this website.  Data is supported throughout our c-Bridge and across to many other c-Bridges. 

 The current line-up of talkgroups and their timers are shown on the talkgroup matrix and it is always the best source for determining what is available on the IPSC Open Manager or any manager for that matter.

Some details, rules and other odd stuff:

We do not support GPS data services.

We encourage the use of a simple programmable power timer (off for 1 minute overnight to power cycle the repeater in case of loss of Internet connectivity) or better, an IP Power Switch ($90 plus; inexpensive to pricey examples: IP9258, Web PS 7, NP-05, ICT-180S-121 ) and that one be deployed with your repeater especially if your repeater will be located a significant distance away from physical control.  This will enable easy power cycling that may be needed from time to time but also and more importantly, it enables powering your repeater off so that network diagnostics can be run when we experience network issues.  Taking repeater off an Ethernet connection remotely vastly simplifies locating a problematic router or Internet connection.  It is also useful as a router failsafe as well as remote control of other AC devices.  We are not asking for control of your switch but only that one be available to help you and us when things go wrong.

Client radios have many more operational settings than your repeater and that programming can have a major adverse impact if not programmed correctly.  DCI has published a standard network codeplug for US repeaters and networks and we highly encourage you to clone or paste in our settings as an example of how best to program for DCI, not so much for the current repeaters, as the plugs tend to become stale.  Then copy one of the DCI zones for your own zone and then change the freq and color code for your use on our network.  DMR-MARC, NorCal and others may have slightly different setting and these setting are customized to match each netwo

More details on how to program your repeater and your client radios for our network operation are linked below.  We strongly suggest that you follow our programming details as it will help the entire network to run more smoothly.  Not all of our suggested programming follow Motorola default settings as we have developed these setting during our  first 4 years of Ham TRBO IPSC experience.  So use ours unless you have more experience and if you do, please share it with us.  We are all about helping others and not keeping anything but our network keys, hidden from the TRBO community.
