I miss good old WIOU. He had some technical insights which were unique,
to say the least.

Yes, but speaker wire is only good for audio up to about 25 kHz. It
has a
frequency limiting component in the wire alloy that must be removed
in order
to use this type wire at RF.
This removal procedure is fairly easy to accomplish. First, soak the
wire
in a bucket of laundry detergent and water over night, then remove
the wire
and rinse it thoroughly.
After assuring the wire is dry, place in an oven set to about 150
degrees
for about 3 - 4 hours.
In lieu of the oven, you can also place the wire in an afternoon of
summer
sun.
After that, place the wire on the ground and hold a 2 meter hand-held
over
the wire, approximately a foot away and key up the radio for 20
seconds at a
couple watts output.
If you see no reaction, sparking, especially tingling in your ears, or
physical movement of the wire, it is now safe to use as an antenna.
