I have some hum in my micpres, so im going to shield the toroid to try to lower it some.
I was wondering, will the shield (two to three layers of tin can) work better if it is on top of the toroid, or will it be enough to have a metal band around the toroid sides and leave the top open? Im not 100% shure how the radiation pattern looks for these things.
Im also worried i might be creating a closed turn if i put the toroid inside the cans with the top up.
