Well after listening all weekend, It's defiantly COE. And more than likely it's the primary operations repeater for All COE operations on Lake Texoma including camping area's, beaches and Law Enforcement patrol. They have Bryan Co. Sheriff on their radios because they laugh a lot at the calls. I think they have channels for Texas Game Wardens as well. They are working both sides of the lake (Oklahoma and Texas) Never could get a repeater input identified. Will work on that Labor Day weekend.
