I don't know if it has anything to do with this one.
Granbury 700 MHz P25 2 site phase II simulcast system. https://wireless2.fcc.gov/UlsApp/UlsSearch/license.jsp?licKey=4480264

Sites 1 & 3 on the new license have the same frequencies as on the earlier license. Site 5, in Somervell County at Glen Rose, has different frequencies. The original license, WRNM607, is licensed to Grangury, this newest license is for Hood County. So, appears to be a 4-site simulcast for Hood County, and one site in Glen Rose, apparently joining the same system. In past City Council meeting minutes in Granbury, references were made to GRRN (Granbury Regional Radio Network). Whether that proposed name will change with the county apparently now participating, I don't know. It will take more review of City County, & Hood County Commissioners Court, meetings to investigate.
