whine with stubby antenna

[wmh9680]

Hi everyone. Hope all were out ridin today. It was beautiful here.

Recently I put a short antenna on my RT LTD and I get a hi pitched whine on 67 am (the Cubs station). I do not get it on FM or any other stations. No Cub jokes please. It is only there when the engine is running. It sounds like when you needed resister plugs in you car to get rid of the engine noise. Any ideas what it might be. Thanks, Mike

you can get rid of that

You can get rid of it by going back to the standard antenna or
installing a 1000 µF electrolytic capacitor in hot lead to the radio.
or you can switch over and listen to the giants hahaha.
sorry to say but that's a pretty common problem when switching the antenna

AM radio? That is always pretty noisy! :thumbup:
The antenna may have made it a bit worse...

Actually I forgot about AM, I probably haven't listened to that early 80's.

Is that anything like a flux capacitor? Seriously, what is that? To me it sounds like when you had a car a while back and the engine noise was reduced with resistor plugs.Thanks, Mike

is this what you are talking about
