CHECKING TOROID CORES WITH A DIP METER , DIP METER TIPS

[@hustonherman7870]

Hi Robert, outstanding video. So I have a dip meter and I am checking some hopefully hf toroids. Question I only have a 100pF capacitor. My readings only deflect the needle somewhat near the end of the scale only. Is this what you would expect? And once I receive the 50pF and use as you illustrated will I have better readings? I do have two 240-43 Toroids from commercial source. Thank you in advance.

I have a HM-10A that was given to me by a friend who is now since passed. He ended up using some foam to keep those coils in place. When the foam wears out, I think I will construct your plexiglas one.

Are any from the computer power supplies any good for RF? I have quite a few yellow ones from computer power supply.

Can we use nanovna the same way?

Very interesting, and I can finally figure out what all these random toroid Coils are for I have

I just got a nice old grid dip meter. This is going to be my first project.
