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.

and clear reception
cannot be obtained
even with a good FM
antenna.
There is multipath interference. Adjust the antenna position to eliminate
multipath interference.
