Hear Clear
There are two components of Hear Clear.
1 Companding:
Reduces the channel noise, e.g. OTA transmission, that is
predominantly present in UHF2 and 900 MHz channel with
the following features.
• Compressor – reduces the background noise flow and the
speech signal at transmitting radio.
• Expander – expands the speech while the noise flow
remains the same at receiving radio.
2 Random FM Noise Canceller (Flutter Fighter):
Reduces the unwanted effects of random FM noise pulses
caused by channel fading under high Signal-to-Noise (S/N)
conditions such as in a moving in a transportation. The fading
effects, heard as audio pops and clicks, are cancelled without
affecting the desired audio signal.
The Random FM Noise Canceller operates only in receive
mode.
Note: This feature must be preprogrammed by a qualified
radio technician. Check with your dealer or system
administrator for more information.
