Very interesting video, but I have a question regarding your results. Many HF radios use an external 12V power supply - does yours? I’ve seen some discussions that such line noise is not likely to pass through the 12v supply, doing away with the need of this filter. Honestly, I disagree. I found that coaxial choke filters, which target common mode noise seem to be more beneficial. Thanks for taking the time to make this video!

Very interesting, I will build one to clear my shack of the noise. Regarding the 3 metal oxide varistors which type are they? Any Part Number or characteristic please? Thanks de M1ENE Stephane

[@sandywallace7362]

Can I ask what size of metal oxide varistors you used

[@gerykis]

What the varistor does why do you need them ?

Will, just came across your video which was very useful. I am in the process of building the filter to resolve my issues. I was considering using "hot melt" glue to secure the can and ferrites. Have you heard of any issue regarding this method? Kind regards Sid M0WCH
