As of January 1, 2013, all public safety and industrial/business land mobile radio systems operating in the 150-174 MHz and 421-470 MHz bands were required to cease using 25 kHz efficiency technology and begin using at least 12.5 kHz efficiency technology, with only limited exceptions.
By ordering and using this MOTOTRBO CPS 25 KHz license you acknowledge and assume responsibility to comply with the FCC regulations and the narrowbanding mandate in the United States. Enabling 25 kHz operation if your FCC license does not specifically authorize such use is a violation of FCC rules and could result in FCC enforcement actions that include monetary fines and other penalties.
