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 multi-path interference.
Adjust the antenna position to eliminate multi-
path interference.
—
The desired station
cannot be tuned into with
the automatic tuning
method.
The signal is too weak.
Use a high-quality directional FM antenna.

Use an outdoor antenna and a ground wire.
This will help somewhat, but it is difficult to
eliminate all noise.

whining noises.
