Digital Audio is making serious in-roads into Oklahoma with a series of DMR machines hitting the air-waves in Oklahoma, and we already have a number of D-Star machines around, now we've added another digital mode called Digital Mobile Radio. Marketed by Motorola INC under the trade name Moto-TRBO. However, you don't need Motorola Equipment to use the mode. Although I am told that for it to have the best network inter-operability The repeater equipment needs to be actual Moto-TRBO. Like D-Star Voice Over IP protocols are used to link the repeaters and users over the internet

147.225 Cheyenne moved to Mayfield
Submitted by wb5osm on Mon, 08/18/2014 - 11:26The 147.225 N0GB repeater that was coordinated for Cheyenne in Roger Mills County is now on the air from a site near Mayfield in Beckham County, close to the border of Oklahoma with the Texas Panhandle. The trustee, Guy Baker, now has a new call sign W5LWV. A PL tone of 114.8 Hz is required to key the machine and it is open to all radio amateurs. We calculated the HAAT of the repeater to be about 120 ft. It should provide good coverage to Beckham county.
