The purpose of the Society is

  • To render public service through Amateur Radio, and
  • 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.

Google Map of Open Repeaters

Map Image Please try out the Google Map page that displays a map with markers for repeater locations. The markers can be clicked with the mouse to display details about repeaters near that location. The location markers are based on the repeater City in coordination records, and are positioned using Google Geocode searches. The map and markers are generated dynamically from the coordination records on the web site. Common Google Map features are available, like zoom, positioning, and others.

Some browsers, such as Internet Explorer or old versions, may be slow to render this map. This is because some browsers are not optimized for JavaScript. FireFox 3.5+ seems to handle it fairly well. I will continue to make changes to improve performance.

Coordinated Repeater Listings for Oklahoma

Repeater information was last updated 01-Jan-2010.

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

This Oklahoma database was published here as of 01-Jan-2010. The database as of Circa 16-Jan-2009 was sent to the ARRL for use in that year's edition of the "Repeater Directory." The ARRL sent the data for the 2009-2010 Repeater Directory to the printer on 30-Jan-2009, any updates received after this date will NOT be published in the 09/10 "RD".

Frequency Coordination Issues and Answers

  • What is a Shared non-protected pair?
  • It was asked about using 145.25 for a network of repeater for disaster work, so one would never be out of range of one.
  • How or who do we work with in the surrounding states?
  • What if someone puts up a repeater in one of the surrounding states that interferes with my repeater?
  • What if the trustee of that repeater says he is coordinated, but it is through a coordination group that we don’t know or recognize?
  • So what about the mess in Texas? What is ORSI doing about it?
  • What is the biggest problem we have here in Oklahoma?
  • Speaking of that, “I want a repeater pair for my area; you say there are no pairs available. You guys have one listed, but I have not heard it on the air for a long time. What’s the deal?

Some of you have changed your mailing address

Some of you have changed your mailing address, please email us with an update of that. If we have too much trouble tracking you down, it could jeopardize your coordination.

Please note

New coordination, unless on 145.25, will only be protected for 90 miles, and must use coordinated PL tones. Meaning, we will guide the repeater trustee in PL selection, so that adjacent repeaters will not use the same PL tone. 145.25 remains as the shared-non protected pair on two meters. We are working on some SNP pairs on 70 CM.
