I installed a mobile and it picks up noise from my fuel pumps I think. They are so many line filters. Which is the best in line filter to try first that may help?
check to see where the noise is coming in to the radio. with every thing on as normal pull the connector for the antenna out of the radio and if the noise goes away you are getting the noise in through the antenna. filters on the power cord will not help you any. grounding and chokes on the fuel pump power wires will be about the only thing that will help. try grounding 1st if the noise is coming in through the antenna.
good luck , this is a hard one to get rid of.
have you tried unhooking the antenna to see if the noise goes away? also what radio are you running ?some times a cheap radio will be rather noisey.
if you know some one with a different radio try hooking it up and see if the noise is better. I assume you have a anl or nb switch on the radio and it is turned on.
