  • To gather and disseminate information concerning Amateur radio operation especially in the frequency modulation mode and repeater operation, and
  • To coordinate efforts and establish standards in regard to repeater systems and associated functions, and
  • To associate with groups similarly constituted in order to broaden the scope and function of Amateur Radio as a service in the public interest, convenience or necessity, and
  • To encourage experimentation by the Society members in advanced techniques in the use of repeaters in order that the general technical excellence of repeater systems shall be improved, and
  • To provide a forum for discussion of spectrum utilization and the achievement of maximum compatibility between various users of the Amateur Radio Bands.

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

Coordinated Repeater Listings for Oklahoma - November 3, 2014

Repeater information was last updated 01-Nov-2014.

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 01-Nov-2014. 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 Any updates received afterwards will NOT be published in the ARRL Repeater Directory until the next edition.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.

The DCS code may be changed if interference with a repeater on the same channel with the same DCS code near Bartlesville occurs. Also on the same tower is an improved version of the 147.33 (+600 88.5 PL) down on the two meter band. The 147.93/33 machine also will respond to transmissions using p25 mode with a NAC of 293, however it only transmits analog FM.
