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.

Can you just buy those ends anywhere? I never heard of a tip and
barrel, but I guess I can maybe find them at Radio Shack.

I have given you the wrong idea. The tip and barrel are descriptors of
the same plug. The stereo head phone jack you used is a barrel contact,
a ring, then a tip. Examine the stereo headphone jack you have and you
will see that there are three contacts (metal areas) separated by two
insulators. You only need two contacts, a tip and barrel. The plug you
need will be the same size but only have the two contacts missing the
small ring contact.

The antenna jack is meant to power a small external antenna that Sony
sells so you do not want to short the two contacts of the jack. Use
insulated wire.

Telamon,

FWIW - The Sony AN-LP1 Active Shortwave Loop Antenna
requires it's own built-in {Set-of-Batteries} Battery Power to
Opperate. The Sony ICF-SW7600GR Radio simply supplies
a small 'sensing' Voltage to only "Switch" the AN-LP1
On-and-Off; and nothing more.

NOTE - This Switching {On-and-Off} Voltage from the Radio
does NOT Supply the needed Power to actually Power the
Sony AN-LP1 Active Shortwave Loop Antenna.

The Sony ICF-SW7600GR Radio has built-in 'protection'
for this small Switching Voltage : When a normal 1/8" Mono
Phone Plug is used with an Antenna Wire and Ground Wire.

The Sony ICF-SW7600GR Radio can be run on (via) an
AC-to-DC Adapter {Wall Wart} while the Sony AN-LP1
Active Shortwave Loop Antenna can be Powered with
(via) Two (2) "AA" Batteries = 3 VDC.
