The US Marshals Service JPATS program is soliciting bids for an upgraded Boeing 737 aircraft to be used for prisoner transports.

Usually "JUSTICE" call signs are monitored on typical Air Traffic Control VHF aeronautical frequencies where the aircraft are operating. I have not seen any reporting of any special aero or land mobile frequency being used for the JPATS aircraft. On the ground, the US Marshals units will probably be using radios to coordinate prisoner loading and unloading.
