Word on the street is that they've upgraded to a fancypants 3 site, 3 channel mixed-mode simulcast.
Well, there are zero, none, nada, public safety related trunked licenses in Erath County. But that did not make them blink a few years ago when they upgraded to P25 conventional without being licensed.
Took a look at the meeting agendas & minutes for the Erath County Commissioners Court back to the first of this year. A couple of comments, one in May, the other June, about a Motorola radio project, plus another comment, in June, about 'discussion for repair to the existing radio system'.
I did find comments in the Stephenville City Council minutes about 'approving a contract with L3 Harris', but no details as to what was being purchased. That might be buried in earler meeting minutes, possibly even last year, but I did not get that heavily into research.
Of course, if either the city or county is purchasing a new system, and using frequencies from the state allocation, as was done for the LCRA sites in Brown County, there would not be a specific license listed in the Erath County FCC license data.
