Wijnand, I would send you my EtherRegen anytime without hesitation so you can try. But there will be duties and taxes and expensive shipping coming from Canada. I know it’s me insisting but I wouldn’t be resisting if I can do without.  And I guess I hope it will help you find answers about the « half »  bits (with John Swenson you never know, he might be close to the answer).

I couldn't resist 😉 , I made my first choke cable, very promising. I tried to share a picture with both of you but this site is really awkward and the most user unfriendly unfortunately (to me at least). No clue how to do that.

Cheers!

Nice! Keep in mind that it could change after an amount of hours

Thanks Paul, That is a really nice gesture. Let me think about it 🙂

Today I have tried to take the core box another step up, but that seemed not that easy. I have tried some extra windings on the main cores. I have tried a second (smaller) cores per pair. I have tried copper tape to create internal shielding. I have tried aluminium foil in layers. I have tried EMI absorbers inside. I have added some cores on the output cable. It all has an effect.

The internal copper tape shielding is a yes!

The EMI absorbers are a Maybe

The pair of smaller cores is a big NO! (A strong field inside the box was created)

The aluminium foil is a no

The extra windings on the main core is a no (because a stronger field is created)

The external cores on the output cable is a yes!

I will soon build a serie of 6 for some friends 🙂
