In this document, the Federal Communications Commission (Commission or FCC) declines, for now, to establish a schedule for Private Land Mobile Radio (PLMR) systems in the 150-174 MHz and 421-512 MHz bands to transition to 6.25 kHz technology; and revises the implementation date of the 6.25 kHz requirement for equipment certification from January 1, 2005 to January 1, 2011.
