Are you confirming this is still using the freqs in the database? I'd like to mark it confirmed in the Wiki if this is the case.
@Ensnared you might want to look through the wiki and at different systems to get an idea of frequencies, TGs and their labels that are being used. At least in NC/SC the systems are set up similar, but with different freqs and modes in the 400 MHz range. I can promise you no federal prison is using FRS/GMRS/MURS. I have done a lot of monitoring of these systems and the labels are pretty uniform such as Compound, Operations, SHU, Food Service, Medical, CMS (maintenance shops), UNICOR (prison factory) and EMERGENCY CH (where you hear radio tests during switch change). You also might get better responses from across the nation starting another thread in the Fed Forum.

At the Big Spring Facility, I heard something I have never heard. I believe I heard the word "riot." This time, the talk groups were quite active. Since I worked in TDCJ for around 22 years, I have heard similar transmission. I am going to have to listen to these recordings at a greater volume.
At the FCI in Big Spring, I discovered two talk groups: 1) one which was different than the control command and main talk group. This talk group transmissions entailed finding an offender within the facility; 2) 2nd talk group, traffic about sharpshooters/shooter patrol. I will have to listen to this again to see if the the transmissions sound like active training or not.
I believe it was a riot since the custody level pf FCI in Big Spring has changed significantly. Originally, the facility had no perimeter fence and offenders were required/allowed to use public/private transportation to get to the unit. I know there was no fence. My father and I were friends with the Warden.
Most of TDCJ have guard towers while others only have perimeter patrol (i.e., Jester IV unit, one of the units where I worked), At each unit with guard towers, has one that stores all weapons excluding their own. For instance, if sheriff's/police departments, even Secret Service and FBI, they had to put their weapons in one of the designated towers that stored weapons.
At the former Ramsey II, where I started, I was allowed to bring my scanner into the unit. In fact, I had one of those 18/48 inch coax dipole makeup outside my office. I did hear about riots there, from rank and building frequencies. I found some of the building frequencies by asking guards to press the radio key with my frequency counter nearby.
I think I finally caught a fish in Big Spring, but I am going to forward these transmissions to my buddy in Dallas, Steve, to let him hear them. I am "stone cold deaf", reference Motorhead. LOL. I am also still sleeping a concussion off, will do this Thursday.
