Can anyone recommend a simple antenna for MW DXing with the Superadio III?
I have a 60 foot long wire outback that I use for SWL. Could this help with
wthe SRIII or should I just use the internal ferrite rod?

Jeffrey - you take that 60 foot wire and attach it to one end of a coil.
You make the coil with a Porridge Oats container - those cardboard
cylindrical boxes that oatmeal comes in. Wind about 50 turns of insulated
wire - any size, usually about #18 will work fine. Hold the turns in place
with scotch tape if you like. Connect one end of the coil to your antenna
wire. Connect the other end to ground (or CAREFULLY to the ground pin on an
AC outlet) with about a 2-3 foot long wire or whatever you need to do to
ground it properly. THEN hold the coil near the MW / AM-band radio receiver,
and you should hear a remarkable increase in signals and dig out ones you
never could hear before. I have tried this trick and IT WORKS!!

You can experiment a bit with what direction you orient both the radio and
the coil in this set-up, but believe e it works WONDERFULLY!
Get the wire antenna up as high as you can and let those signals roll in!

The length should be at least 50 feet. 100 feet is even better.
The far end should be as high as possible, but just whatever you can manage
will be a major improvement over just the radio by itself or with a whip
antenna!

Hi Brian,

I intend to make one these coil antennae for my Sony 2010.  Would you
please address the following issues?

1) What is the approximate diameter of a Porridge Oats container?

2) You talk about winding 60 ft of wire and in another place you refer
to 50 turns. Which one is more important the lenght of the wire or the
number of turns? or Does it matter?

Quote:> Connect one end of the coil to your antenna wire.

3) Do you mean to the whip antenna? or Do I need to have a long wire
antenna attached to the radio before I even think of this coil antenna?

Quote:> The length should be at least 50 feet. 100 feet is even better.

4) Is this referring to the length of the wire on the coil or to the
wire used to make the long wire antenna?

Regards,

Carlos
