I found a bag of small toroids in my parts box. They are 3/8 dia with 1/8 doughnut hole, wound with 5 turns of 26ga twisted pair. No idea what the mix is. What good are these to me? They probably are RF chokes for something but no idea what. Any ideas? Thanks and 73, Dick KF4NS St Petersburg, FL 33714 USA Keep The Glow!
