  • 1/31/07 - Towns to buy 113 cop radios (By Susan DeMar Lafferty SUN-TIMES NEWS GROUP)
    • Frankfort, Mokena and New Lenox are teaming up to purchase new radios for police officers. 113 800 MHz units will be bought with grant funds from a settlement agreement under the Telecommunications Infrastructure Maintenance Fee Act. The new equipment will allow all of their police officers to have a portable radio capable of communicating on Will County's 800 MHz system, and be used as a backup should the Lincolnway radio network fail.
    • Ultimately, this would become their primary source of communication as they transition to this new 800 MHz technology, Mokena Police Chief Randy Rajewski said. Mokena and New Lenox decided to share the funds with Frankfort because they rely heavily on each other for 911 services, Chief Martin said. "This benefits every officer on our network," Chief Rajewski said.
