FM
FM stereo reception is
noisy.
The characteristics of FM stereo
broadcasts may cause this problem
when the transmitter is too far away or
the antenna input is poor.
Check the antenna connections.
Try using a high-quality directional FM
antenna.
Use the manual tuning method.
There is distortion, and
clear reception cannot
be obtained even with a
good FM antenna.
There is multipath interference.
Adjust the antenna position to eliminate
multipath interference.

eliminate all noise.
