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.

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.
