## Abstract

In this document the Commission revised the duty cycle specifications for stolen vehicle recovery system operations on 173.075 MHz by adding a new duty cycle option of 1800 milliseconds every 300 seconds, with a maximum of six messages in any thirty-minute period. This action was taken to enable the enhancement of police performance in the recovery of stolen vehicles and apprehension of suspects. This rule change will facilitate: more efficient law enforcement, a decrease in the time between when a vehicle is discovered stolen and when the theft is reported to the police, greater stolen vehicle recovery rates, and a greater rate of apprehension of criminals.
