Thats going to be hard to follow any new tower locations and frequency changes.It seems RACOM has a wide-area license allowing them full use of the PS TRS spectrum.
ULS License - SMR, 806-821/851-866 MHz, Trunked License - WPIZ405 - RACOM CORPORATION
That is the license they operate under now. It is the only YX Service license still active under their FRN. Im not real clear on how that works, i think they just need to coordinate with other operators in the area and as long as they do not cause interference they are given free reign. I may be wrong about that tho.
