Cherokee SO NXDN or MOTOTRBO?
Well this is interesting. The Clay system is definitely NXDN but I'm not so sure about Cherokee. A quick check on the FCC website for their 158.970 MHz license shows a 7K60FXE emission code. That isn't NXDN but MOTOTRBO 7K60FXE (voice). That is definitely an interesting development.
