Subject: Radio Shack got out making shortwave radios?
I was in a Radio Shack for the first time in about a year and I notice they
no longer sell their own models but sell Grundig, etc. Did Radio Shack get
completely out of making the DX series?? There must be some good discounts
out there somewhere on the DX models if that is the case.

The deep discounts were a little over a year ago, around Oct-Nov 2002.  I
picked up two DX-396s for $50, a DX-402 for $50, and a DX-398 for $99.
Basically I got all four radios for the list price of the DX-398 alone.

I gave the DX-396s as gifts, but still use the DX-402 and DX-398.  Both are
very good radios.

    Agree with Bob's response, but also think it's worth pointing out
(given the original header of the post) that, to my knowledge, Radio
Shack *never* "made" their own radios.  Some of their stuff is "made to
their specifications" however you want to interpret that, but I don't
think they have their own manufacturing facility for anything, and don't
know if they ever did.  The DX-402 Bob refers to, for example, was made
by Sangean.

Don't forget those portable cassette decks they have been having made by
Hitachi for 30+ years.. even the style hasn't changed much.. :)

SNOW,

A long long time ago many of RadioShack's Radios were made by Hitachi.

Then for many years, RadioShack used to Re-Badge other manufactures
radios and equipment with there own Brand Names.

More recently, Sangean has made most of RadioShacks "DX" Series
of World Band Radios.

Today RadioShack is becoming a Brand Name Re-Saler: Grundig; RCA;
Sprint; Dish TV; Direct TV;  and others.  (A 'mini' Circuit City)

Speaking of Radio Shack, I was real disappointed in their sales people
a couple of weeks ago when I purchased their SW antenna kit.  I'm an
electronics dummy so I asked them some very basic questions about
hooking the antenna up to my Sony 7600GR....like hooking up the lead
in wire to a plug (which I bought from them) that has a hot pin and a
ground sleeve.  They had no clue.  First they said hook it up to the
ground, then the hot, and finally both!  This happened at two stores.
I remember not too long ago when their commercials bragged how their
salespeople were electronics experts....well, now they don't even know
the basics of the stuff they sell.

The URL is still good but the product is now named:

    C. Crane AM Antenna with Twin Coil Ferrite (TCF)

If anyone wants a very well-done review, throw +stinger and +"justice
antenna" into google.

I said I'd give an "informal" opinion on it.

My observations are:

   1. On many frequencies - both day and night - I will be receiving
absolutely nothing but static + rushing noise with the CCRadio+. When I turn
on and tune the CC Antenna, I'll get a reasonably strong station "most of the
time" (subjective).

   2. Particularly at night but - occasionally during the day - I can, by
tuning the antenna, actually get two stations on one frequency and get both
of them quite well enough for them to be "clear (or "4x4" if you like that
sort of rating).

The antenna works.

I'm in a horrible location over the river and under the hill and with only a
sealed-window facing South for an indoor antenna. I have the antenna itself
at the midpoint (where the top and bottom meet).

A very impressive antenna.

They're only minimum wage droids who barely have enough knowledge to
flip hamburgers (their last job). I went to a RS for something and the
store was empty so I got to talking with the salesgirl clerk. She said
that she makes $7 an hour, took the job because there was nothing else
available and she didn't have a college degree (this was a few months
after the terrorist attacks), and is trained to sell cellphones. She
said that people ask her questions about "that stuff back there" (the
parts section) but she doesn't know what it is, much less what it's
meant for. She said I knew more about it than she did.

But the point is they didn't make radios. Most of their SW line was
rebadged Sangeans, except for the DX396 and maybe another model, which
were made by a company in China that I never did find out who it was. I
had a look at the radio line of one of the biggest RS's in my area and
they sold only two SW capable radios, the Grundig YB400 and the Grundig
windup. Shortwave must not be too popular these days, or else the
cellphones have greater profit margins.

Hi, Gray!

Yeah, the folks left at C.Crane renamed the Chris Justice Antenna (now that
he's no longer with them -- he's at RadioLabs).

I agree with everything you wrote about it.  If you live in an accidental
"Faraday cage" because of metal studs or siding, it's a great way to bring
in strong AM signals.

Also, to answer another post, yes -- it is directional, but I don't find it
as quite as directional as a CCRadio+, even though it has two of the same
8-inch ferrite coils in it that the CCRadio has.

Your reading comprehension needs work. The claim was that RS ever made

STINGER,

I would Agree with your assessment of the Justice AM Antenna.

"Also, to answer another post, yes -- it is directional, but I don't
find it as quite as directional as a CCRadio+, even though it has
two of the same 8-inch ferrite coils in it that the CCRadio has."

To me Justice AM Antenna by C. Crane Co. is a "Great Signal Magnet"
for those who are in locations that have very poor AM/MW Reception.  

*  The Justice AM Antenna is directional but not as directional
as a Select-A-Tenna Model 541-M; or a home made Box Loop Antenna
of about 15" or bigger.

*  The Justice AM Antenna's 'advantage' over the Select-A-Tenna
Model 541-M; or a home made Box Loop Antenna of about 15" or bigger;
is that is an ACTIVE "Tuned AM/MW Antenna" and because of it's
built-in Amplifier the Justice AM Antenna has more Gain.
SAT=> http://www.selectatenna.com/

IMHO:  When compared to the Quantum "QX" Loop Antenna or the Kiwa MW
Air Core Loop Antenna:  The Justice AM Antenna is NOT as Directional
as those two.  
QX=> http://www.dxtools.com/PRODUCTS.htm
KIWA=>  http://www.kiwa.com/kiwaloop.html

FWIW:  For me the Justice AM Antenna will Always be the "Justice
AM Antenna (JAMA) that is sold by the 'c. crane co.' .
JAMA=>  http://www.ccrane.com/justice_antenna.asp

TBL:  The Justice AM Antenna is the 'best' VALUE for the $100 of
any of the Commercial AM/MW Antennas on the Market Today.
- PENDING - The Release of the upcoming "PETE [KE9OA] MW Loop Antenna".

All small antennas have the same nulls, the problem being that
they all have two patterns: a magnetic field pattern (with infinitely
deep nulls), and an electric field pattern (with infinitely deep nulls)
that doesn't null anywhere near the same place.

So in the nulls of the magnetic field pattern, you hear the electric
field signal instead of silence.

Careful balance and symmetry can eliminate most of the electric
field response, and that's how you get deep magnetic nulls.

If it's on the end of a long cable, it starts picking up electric
field again.

You can make it less important by having the first amplifier at the
antenna itself.

The passive MW loops work not by gathering signal (signal magnet) but
by matching impedance.  Active ones work by having a lower internal
noise level than the receiver they front for.

RH,

Well my simply (No Theory Required) Empirical Evidence using several
small commercial AM/MW Loop Antennas: RadioShack AM Loop Antenna;  
Terk AM Advantage Loop Antenna, and Select-A-Tenna Model #541-M.
That there were differences in the Peaks and Nulls of each Antenna
when used with a variety of small 'portable' radios.

Even the Kiwa MW Air Core Loop Antenna and the Quantum "QX" Loop
Antenna have different Peak and Null characteristics when I have
used them with my Kenwood R-5000 and Icom IC-R75 (R-75).

When I compared the Justice AM Antenna (JAMA) to the Select-A-Tenna
(SAT) Model 541-M the Peaks and Nulls were different.

The SAT had a relatively Sharp Peak and Normal Null.
- If you move the SAT 'off' Peak by 30* you could see the Peak fall-off.
- From 30* to 80* the Signal would taper-off uniformly.
- From 80* to 90* the Signal would decline further to the Null.

The JAMA had a Wide Peak with a Sharp Null.
- If you move the JAMA 'off' Peak by 30* you would not see the
Peak fall-off as much.
- From 30* to 80* the Signal would not change greatly.
- From 80* to 90* the Signal would dramatically fall to the Null.

This Is Why I Say:   The Justice AM Antenna (JAMA) is a Good Signal
Magnet for weak AM/MW Signal Locations.
