I'm once again considering winding high power chokes with enameled wire. Zo of a closely #12 pair is about 53 ohms, which makes it desirable IF breakdown voltage is sufficient. I would appreciate for
Have you thought of using a 1:1 balun of the guanella type? I built mine using RG400 and one core. No signs of problems at the legal limit and 2:1 SWR. -John NI0K Jim Brown <mailto:jim@audiosystemsgr

Greetings to all, I agree with Grant Saviers, KZ1W, on recommending Tempco magnet-wire. Tempco guarantees their product to be USA manufactured. I use their GP/MR-200 grade magnet-wire rather than the
Hi Jim, As you probably know a Class 3 insulator material is best. Some enamels work well at 105C temps, FormVAR variants etc... If you think it will run hotter there are materials that go a lot high

Understand your preference for enameled wire. On the other hand have used the Salas-recommended wire (see link below) with no problems at HV. http://www.ad5x.com/images/Articles/Current%20Balun%20Rev

Dumb question ... is the insulation sufficiently flexible that it will not crack when wrapped around the toroid ? 73, Dick, W1KSZ _______________________________________________ _____________________
