Coordinated Repeater Listings for Oklahoma - September 15, 2015

Repeater information was last updated 15-Sep-2015.

The ORSI board voted to list all coordinations, where a trustee requested non-publication, we will only publish the frequency, city, county, coordination date and update dates. Then show it as a closed access repeater.

This Oklahoma database was published here as of 15-Sep-2015. The database is sent to the ARRL for use in their annual edition of the "Repeater Directory" at the start of the year (January). Any updates received afterwards will NOT be published in the ARRL Repeater Directory until the next edition. However, we will continue to update the listings on the ORSI web site periodically during the year.

DMR Repeaters Accidentally Left Out of Database

The April 5th update of the coordinated repeaters for Oklahoma left out the new DMR machines that are popping up around the state. The software problem has been fixed, and a new update will be posted again soon. DMR repeater trustees do not be concerned, your machines are in the official coordination database. They just didn't get published on the web-site. I am also working closely with Bob W5RAB on getting the information correct on the DMR repeaters in Oklahoma. I am also working with ARRL on getting all the digital audio machines published correctly in the ARRL"Repeater Directory".

Digital Mobile Radio Comes to Oklahoma - aka Moto-TRBO

Digital Audio is making serious in-roads into Oklahoma with a series of DMR machines hitting the air-waves in Oklahoma, and we already have a number of D-Star machines around, now we've added another digital mode called Digital Mobile Radio. Marketed by Motorola INC under the trade name Moto-TRBO. However, you don't need Motorola Equipment to use the mode. Although I am told that for it to have the best network inter-operability The repeater equipment needs to be actual Moto-TRBO. Like D-Star Voice Over IP protocols are used to link the repeaters and users over the internet
