Technical CB Radio Interference

As said before, solid copper plug leads will emit lots of RF and get into any radio system operating. There are (maybe not available anymore) resistors which would be connected in series with each plug lead which would quieten them down. I liked seeing people in cars around me at the lights fiddling with their radios when I pulled up in my copper-leaded stovebolt (no radio in mine of course) trying to figure out where all the popping noise was coming from. I reckon you could have heard it from the moon!

 

I have no idea what plug wires are on the car.
I’ll look to see if there are any markings on them.

 

Or measure resistance. Solid metal should be just about zero, so anything meant to have resistance should be obviously different.

 

You guys can hear the radio when the car is running…. ?

 

The woody is fairly quiet,
It’s garage mate not so much

 

Hell yeh

 

There is already a condenser at the points on a traditional ignition system. Or are you saying there should be one on the ignition power lead on the coil?

 

I assume he means a capacitor on the power side of the coil, to filter out some of that switching noise that otherwise spreads through the power feed to the rest of the electrical systems. A coil or ferrite on the power lead should improve the situation even more.

 

On the power lead to the cb would be a big help too.

 

That’s what I used as a kid. Was a coil with two leads on it. Killed the alternator buzz/hum I had. But was for a stereo.
