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?


Yes but it needs to be a mono jack with two conductors tip and barrel.


Connect the wire to the jack tip for a single wire 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?


If you want something better use two wires, one to the barrel and the
other to the tip. Stretch the wires in opposite directions and you have
a dipole. Make sure they don't short to each other inside the jack.


If it ever gets a short, it will not damage the radio, at least
permanently right? I mean since it's not like electricity going
through or something, right?


The jack is meant to power a small external antenna amplifier that Sony
sells so don't short the two contacts in the jack.

Though, will it ever damage the radio?
