Hello all, I have a bunch of cores in my junk box and would like to make use of them on 160. Is there and easy way to test the frequency range they are good for? I have a GDO, MFJ 259B and other test equipment, Thanks, Rick Darwicki -= N6PE =- ================================================= 17775 Elmhurst Circle Yorba Linda, CA 92886 http://www.qsl.net/n6pe/
