I have a fairly large amount of insulated copper wire, that is solid.
My Sony ICF-7600GR, has an external antenna jack that is just
basically a headphone jack with it's connector. Isn't it possibly just
to put this insulated wire on a 1/8 jack and make fairly ok antenna? I
guess you can't just use any end, I used one from an old pair of
headphones that broke for the heck of it to test and it barely got any
signal in. Am I wrong about using copper wire like this?
