Fix car radio static
old post, and my first radio noise post.
im an old radio guy USN, and ex ham.
Q1: AM or FM? (even on cassette or CD?)
1: bad antenna, and for sure, there are upgrades !
2: too far from station, AM is worst for static, but FM has shorter distance for same station power. (I heard XERB in VietNam! AM)
3: bad radio. (rare for both am and fm bad)
4: bad alternator can sing, play with throttle and it sings higher for higher RPM bingo. stop engine, singing gone?, bingo. Alternator.
5: and last ignition noise, so stop engine still have ignition popping sounds. no more? , then Ignition noise, clicks or pops. (spark)
6: noise has 2 sources , radiated or conducted.
if conducted on power line, 12v to radio , we can buy a filter to stop that.
older cars do this. what year is yours. a honda what a 73 civic?
