Some Surrounding States Starting to Put Repeaters on What Were Simplex Frequencies

We've recently received some clearance requests from AR and I believe MO to clear repeaters on frequencies like 145.45. Which have traditionally been used for FM simplex. I believe they are using these frequencies for some of the digital audio modes, such as DMR. They might be simplex DMR hot spots, since 145.5 to 146.0 is reserved for amateur satellite operations. Otherwise they may be using a + offset. I'm not sure how this works. However, bottom line, if anyone knows of organized or semi-organized activities on two-meter simplex frequencies in eastern or northeastern Oklahoma, please let us know so we can let the coordinators in the surrounding states know that a repeater operation on those frequencies might create a problem.
