3.3 Receiver
3.4 Self-Quieting Frequencies
Self-quieting frequencies are frequencies that are also generated by the radio and cause internal
interference.On these frequencies the interference caused by the self-quieter spur is great enough
that a radio will not meet its receiver sensitivity specification.
The frequencies are: Midband 67.2, 83.78 and 84MHz.
