ORSI Frequently Asked Question

What if someone puts up a repeater in one of the surrounding states that interferes with my repeater?

Before anyone puts up a repeater in a surrounding state, the frequency coordinator for the state involved contacts me and the coordinators in other affected states and notifies us of the proposed coordination, we call the process need of professional courtesy. So normally this does not happen.
Now one of the things we get into is the different states have different separation standards, and in the case of two meters and Texas a slightly different band plan. This usually leads to a bit of negotiation among coordinators and we do our best to resolve the issue.

ORSI has good working relationships with the Arkansas Repeater Council, Missouri Repeater Council, Kansas Amateur Repeater Council, Texas VHF-FM Society, and have rubbed elbows a bit with coordinators in Colorado and Louisiana.

We never intended 145.25 for this use. There are several wide coverage networks already in place, and the beginning of a state-wide UHF backbone. We have the SWIRA link for SW Oklahoma, and the TARC Super System for Eastern Oklahoma and Western Arkansas. It has made some inroads to central Oklahoma with nodes in Stillwater and eastern Logan County.

On the two meter band we have designated 145.25 MHz for use a shared non-protected pair. To put a repeater on this frequency, you do not go through the normal coordination process. It is wise to apply for the pair.
This is for low elevation and low power machines; preferably less than 100 feet HAAT, and less than 100 watts ERP.

By non-protected it means you have no halo around you that someone cannot put a repeater on the same frequency.
