I have a Nissan Car radio with shortwave, and its sensitivity suddenly dropped on AM & SW. FM still ok.




What to do?










Rod antenna? Active stub? Active on glass?


Without an antenna FM reception would be extremely poor in a car.


My AM and FM antennas are separate, both on glass. There is an FET line
driver involved for the AM. This is a likely point of electrical failure
as we all learned from Sony way back in the 1980s.
