This aggregation project is primarily an effort to assist travelers and visitors interested in using local area IPSC TRBO repeaters.  Novice TRBO programmers might also find this plug informative.  This codeplug doesn't attempt to include specialized talkgroups or other features for each network.  Our efforts are more to show programmers how to set-up zones, modes, RX groups, scan and roaming and how this all interacts.  Otherwise, our plug enables quick and easy access to the main or common talkgroups on networked repeaters.  As far we know everything contained in this codeplug is public information, with correct or best tech settings for each network and we assume that traveling hams are welcome to use these USA repeaters.  If otherwise, see paragraph 5.

Currently, this codeplug has listings for DCI, TRBO-6, NorCal, DMR-MARC, and NC PRN IPSC Networks as well as a few cBridge Talkgroups.  It includes Talkgroups and RX Groups for each network, Scan, HT and Mobile Roaming lists for NorCal, as well as sampler zones and scan lists for FRS, GMRS and the Win System.  This may also be useful information for setting up your own codeplugs.

We have also adopted a National TRBO Simplex frequency (446.075) as well as a few others as alternates and now include a "Simplex" zone in the codeplug.  This should be useful at Hamfests, Conventions and commercial or industry gatherings for those areas which may not have an available TRBO repeater or for those who don't have the local repeater programmed in their radios.  Catch the discussion in our MTUSA Yahoo group. UHF and VHF frequencies/talkgroups are also located in our repeater listing page.

The latest DMR-MARC "Contact" list is included for all USA based hams.  Any additions or corrections in the digital "Contacts" should be taken up with DMR-MARC directly as they have dedicated substantial energy to maintain a complete world-wide listing for all Ham TRBO interests.

This is a new project and this codeplug release may contain typos, stale info or omissions.  You may send corrections, additions, deletions or new network information to DCI to be included in or deleted from the next update of this plug and webpage.  If you have any other TRBO talkgroup/timeslot combinations as well as open analog repeaters useful to TRBO travelers/visitors, that information is welcome and may be included in the local zone, primarily on a zone space available basis (ie: 16 modes max per zone in an HT).

Lastly, our work here is in part, the work of other networks that put in the labor to share their information.  We appreciate the openness of these groups which enables far smoother network operation as much as providing local users access to their repeaters.  You might even send a word of thanks to your local repeater and cBridge owners as their efforts are not insignificant on many levels.

Our "sampler" is a UHF XPR-6500, rev R01.08.00 codeplug.  It is relatively easy (as best as CPS allows anyway) to "Clip N Paste" into an existing codeplug.  You can bring in all or part of this plug. 

If you plan to use the zones and/or modes, manually create the associated RX groups and Scan Lists (they can't be pasted in) using the identical names BEFORE pasting in,  1)  the Talkgroups (group calls; if not the entire digital contact list), then,  2)  the zones or any modes in any zone.  If you do this out of order or incorrectly, your pasted modes will loose the needed "RX Group list" and "TX Contact name" entries.  Remember to go back and populate the RX groups and Scan Lists as now the info is in the plug to populate both.  Hints on how to best approach this process is in "Codeplug Pasting" if you need additional help.
