From the Placer County Interoperability Network P25 radio network. Primarily covers Placer County Sheriff's but also includes the P25 talkgroups of South Placer County Fire District and Placer County Fire.
This is a feed from Site 001 of the Placer Countywide Interoperable Radio Network (CIRN). My receiver is using an RTL-SDR dongle and the SDRTrunk software. My system is set up in the City of Roseville using a small antenna in my computer room. I am feeding the Placer County Sheriff's Dispatch talkgroups, as well as the South Placer Fire District and Placer County Fire dispatch talkgroups. I do not know if those talkgroups are actually active, but at least the sheriff talkgroups are active.
Temporary note: Currently, this is operating on my primary desktop machine, for the purposes of troubleshooting but my ultimate plan is to place it on the same machine that is already feeding the City of Roseville P25 network.
