Radios operating with a 12.5 kHz channel spacing shall transmit with a minimum FM hum and noise ratio of 34 dB. Receiver Performance Characteristics Radios operating with a 12.5 kHz channel spacing shall support a minimum of 200 channels and be able to receive on an number of channels that will be provided “as needed” to the vendor when a procurement order is initiated. Radios operating with a 12.5 kHz channel spacing shall support a minimum 20 MHz frequency spread be able to receive over an UHF Band frequency spread “as needed” that will be provided to the vendor when a procurement order is initiated. The radio receiver audio output shall achieve a minimum of 12 dB SINAD using a reference sensitivity of 0.35 uV at the receiver RF input. The maximum audio output power shall be a minimum of 0.5 Watts of sound pressure level. The audio distortion with maximum audio output power shall be less than or equal to +/- 10 %. Radios operating with a 12.5 kHz channel spacing shall receive with a minimum adjacent channel rejection ratio of 45 dB. The spurious response rejection ratio shall meet or exceed 70 dB. The intermodulation rejection ratio shall meet or exceed 70 dB.
