I think it came with the Tecsun R9700DX, but I cant remember for sure.

It's a 30' wire black insulated wire with a plastic alligator clip on one
end.
I've never used it much.

One evening recently, I decided to open the window, and drop the wire out of
of the small space between the screen and the window frame. I clipped the
end to a variety of portable receivers.

Sony-7600GR
Grundig-YB-400
RS DX-398
RS DX-202
Kaito KA-1103
Kaito KA-1107
Tecsun R-9700DX
Tecsun-PL-230

The results were impressive. It gave the portables stronger receive, better
clarity, and improved sensitivity.

The 1107 strugged with selectivity, but the rest performed well.
I have used that a few more times, when the weather is cool enough to open
the window, and turn off the A/C.
I'm anxious to use it this fall.

SWLO-2010 - What 'works' . . . WORKS ! ~ RHF

-IF- you have two Windows try running/routing
the Wire across/between the two Windows
so the the Wire Antenna Element is Horizontal
vice Vertical - Sometimes this will help to
reduce the local Noise pick-up of the Antenna.

Here are a few 'other' simple Wire Antenna Ideas to use
with 'portable' AM/FM Shortwave Radios in an Apartment :

You might want to try out one of those small magnetic loop antenna's.
They allow you to null out any interference from the apartment and
generally they pick up less noise anyway. Put it on a stick and direct
it out of the window...

Experimenting with antenna's should be half the fun of shortwave
listening. Its the most important part of the listening station and
theres sooo much to gain, especially in challenging situations such as
you are in yourself!

Thats a good idea.

I do a lot of experimenting and improvising with antennas. I have a Kaito
window loop I bought a few months ago, and it's actually not to bad for the
price. I've been at this apt. living and SW-listening for quite some time
now. I'm going to add a section for atp. dwellers on my website.
And, not just for antennas, but how I made up my own work benches on
casters, so when you're not it, you can just roll it against the wall and
use it for a shelf. You can screw a power strip on the front, and use an
extension cord, so you can solder, drill, or plug in any AC device or wall
wart. They also make a good recharging station for cell phone, batteries, or
anything that needs a charge.

Another example. I figured out a way to make cradles for portables
receivers, that you can put at just the right angle for your pleasure. I got
the idea when the back stand broke on my favorite portable receiver, my old
and trusty DX-398. Then I realized the size I was using was perfect for the
larger portables like the Grundig S-350, S-350 DL, and they fit my new
KA-2100 as well. It's nice to sit them at a convenient angle.

You can make 2 of them for about 5 bucks.
How can you beat that?
I have to photograph. them and then add them to the site.

I would love to be able to do that, but each room has only one window, and
I'm in a high rise with no balcony.
You know, if a guy had an apt with a balcony, he could really come up with
some good configurations.
But, since I don't, I just have to do what they told me to do many years ago
in the Army...Adapt!

Thanks for the links.

JFTR, this was probably caused by overload - this kind of receiver
concept (borrowed from Sony's dual conversion multiband portables)
generally has a fairly poor dynamic range.

What you've proven (again!) is the old adage of "get it outside, get

All the fanciest actives/indoor loops etc. can't compete with a Good
Piece of Long Wire in Fresh Air.

A poor receiver with a good antenna will out-perform a great receiver
with a dubious antenna.

SG,

Overload Reducing Shortwave Listening (SWL) Antenna
for 'portable' AM/FM Shortwave Radios in an Apartment
http://groups.yahoo.com/group/Shortwave-SWL-Antenna/message/13687

The webpage written by by Tom Sevart [N2UHC] describes the
construction and set-up of the Portable Wire Antenna [ PWA ]
to be used with the Sony ICF-2010 and other Sony 'portable'
AM/FM Shortwave Radios like the ICF-SW7600GR.
PWA=> http://www.geocities.com/n2uhc/portablewire.html
- - - To 'quote' Tom Sevant [N2UHC]
"This is an antenna I put together after having problems
with overload on my Sony 2010 portable shortwave receiver"

FWIW - Basically, the PWA is a a Short to Medium Length
(30~50 Feet) "Random Wire Antenna" that is 'couple' via a
a 'portable' AM/FM Shortwave Radio's Whip Antenna for
improved radio reception.

HOW-TO-USE-IT - Place the "Coupling Coil" :
http://groups.yahoo.com/group/Shortwave-SWL-Antenna/message/306

#1. Vertically [Over] the 'portable' Radio's "Partially Collapsed"
Whip Antenna for Improved Shortwave (SW) Radio Reception.
- - - Vary the "Length/Stub" of the Whip Antenna to 'adjust'
the amount of effective coupling and SW Signal Transfer.
PWA=> http://www.geocities.com/n2uhc/portablewire.html

#2. Vertically [Over] the 'portable' Radio's "Fully Extended"
Whip Antenna for Improved FM Radio Reception.
PWA=> http://www.geocities.com/n2uhc/portablewire.html

#3. Horizontally [Near] the 'portable' Radio's AM/MW
Ferrite Rod Antenna for Improved AM/MW Radio Reception.
PWA=> http://www.geocities.com/n2uhc/portablewire.html
- - - Adjust the 'position' of the Coupling Coil to vary the
amount of Effective Coupling and MW Signal Transfer.
