Ham operators notice antennas all over your plane like on a car the exhaust system in a big antenna we use flat braid from exhaust to ground on that, just example of how to fix noise on other devices.
The audio quality on this video is freaking fantastic! Perhaps you could teach others how to record sound for their videos. Oh, and thanks for the info on ferrite chokes. Peace.
Hello I have an idea I would like to run past you. I would like to get rid of the interference on my home stereo. Do you think using these on my my speaker wire right before they go into the speakers would help?
Good video! In my plane (@KUES) I notice that if my daughter plugs in her iphone to one of the 2 usb jacks in the adapter that is in the old lighter socket (24V) I get radio interference. Do you think a core around the usb cable might do it or just replace the usb adapter jack? I noted that the other usb jack in the adapter does not create noise. Thanks.
If you can get behind the panel and put the ferrite core on the wires then you'd be better off. I don't know if putting a core on the cable would work but it would be super easy to try.
You may have static coming from the engine and spark plug wiring. Be sure your engine block is grounded to the frame because rubber shock dampeners will insulate the engine from the frame. Shielding over spark plug wires is a good idea, but be sure the shielding is also grounded to the engine and frame.
I do not fly with a compass so I don't know for certain how it would affect one. The magnetic cores are not terribly strong so I expect very little effect on a compass outside of a 2 or 3 inch radius
Interesting question - cores are basically not magnetically polarised (not strictly true but any renmance is extremely minimal and will not affect a compass deflection significantly) Additionally, the cores, even if split, for a torus and like toroidal inductors minimises flux leaage due to their shape. I won't say that surrounding a navigational compass with a lot of ferrite cores won't affect it, but certainly we're not into compensation or adjusting territory here. Theoretically, if there's a heavy current flowing through the wire and the orientation is just so, then yes, a mangnetic field will be concentrated by the ferrite core but not as much as you would imagine - supression cores are designed to be "lossy" to reduce their loaded Q-factor. This means that although there is a transformer or coupled inductance effect, it is in no way comparable to a solenoid-style inductors or transformers where losses are minimised to optimise EMF efficiency. As high current wiring should not be positioned close to a nav compass anyways then I doubt there will be any significant effect in a typical installation scenario. If there is, a quick compass base check will prove or disprove problems. Not the ferrite cores we're talking about here are very specifically for EMC/RFI suppression and are not random magnets - like I say above the composition is very specific and totally different from magnetically polarised materials. In addition, note that ferrite materials used for suppresion purpses are distinct from those used as RF transformers (baluns or ununs) though to the casual observer they may appear similar. As a general rule, split cores (surrounded by a plastic clip) are almost always suppression cores. Whereas ring cores (unsplit, a complete torus shape) maybe sometimes be for supression, OR transformation/inductor purposes. Stick to split cores. edit: not all ferrite compositions are magnets, though some magnets are ferrites
I really like this video. I do have a question for you and hopefully you can help. I have a cb radio in my semi and have led headlights, everytime that I turn the headlights on I get radio interference through my cb. Will these ferrite collars help with interference and where should I install them? On the power cord or coax to antenna? Radio is wired direct to the batteries of the semi. Thanks in advance.
The ferrite core would go on the power cord to the radio. You may have current being induced on the power wires by other electrical components. Place the core as close to the radio as you can, that will do the most to trap and reduce the noise.

You can get a RG58 one for your external aerial cable put it close to the aerial end. Or use 2 one at each end.
An excellent explanation! This is a very simple solution to a complex problem. Thank you for posting.

Thanks! I do try to create good content.
very good. take it easy in that light craft
you need to change video name to how to make ferrite core as isolation for radio to make video appear in suggestion , cause it's useful one
Thanks for the suggestion, I will do that

thanks for sharing
Like and comment to help the channel.
excellent
my friend suggest me to wrap aluminium foil on ignition coil cable so it can’t interfere with other sensors frequency … will it work ??

thnak you
great idea i will use with car radio
did it actually work? thanks.
@@betavirus11 yes but it will need other capacitor
Did it affect your compass?

So is this the easy way you are talking about?
Yes
