In Bowling Green they used the county's radio system along with the SO for the bust. I did not monitor any of their specific frequencies, but I know they used the local system heavily. They called each other KBI1, KBI2, etc. They also did not sound real seasoned on the air, not bad, just as if they don't use the radio often. I would guess the channel is rarely used. I will ask some of the SO involved to see if they saw them operating on their own radios.
