Bollinger County EMS is licensed for MotoTrbo with a tower at the sheriffs office (WNIJ977).I'm pretty sure you aren't hearing DMR traffic from Bollinger Co. SO - I think what you are hearing is encrypted P25. BCSO is routinely heard on MOSWIN on the Bollinger County Travel (TG 4002) coming over to Cape County Jail for prisoner runs with multiple UID's for the vehicles (i85xxx series). Additionally, no current FCC license shows an emission grant for DMR on 155.520 MHz and no legitimate radio shop would set up a system when the licensee isn't authorized to use it . I just can't see BCSO spending that much money on a DMR system when they have MOSWIN radios in all of their vehicles.
