STEVE,

Hello Steve, et al ...

I am not familiar with your shortwave receiver, but perhaps you can tell
me the
receiver controls on the front.

Most communications receivers will have certain circuit designs that
will prevent
"overload", such as an automatic gain control [AGC] which automatically
attenuates large amounts of radio frequency [RF] energy entering the
first stage
of your tuned circuits. If your receiver does have an AGC switch, try
turning this
circuit in the on position and see if there is any difference.

Good communications receivers will have one to two stages of RF
amplification
circuits which are designed for selectivity. These circuits are
manually controlled
by a control on the front of the receiver called an RF control. By
decreasing the
RF control you will decrease the amount of RF amplification and bring
back the
selectivity to the front-end stages. Look in your instruction manual
and see what
your Intermod-Distortion [IMD] specifications are. This is the ability
of your
tuned circuits to reject received signals from heterodyning with the
local oscillator
[LO] during the mixing stage.

After you have read your manual and are satisfied with the ability to
control your
receiver correctly, I will be happy to suggest various external
wide-band antennas
that are simple to construct.

Hi Guys
Im really disappointed that I buy a Sangean 505 shortwave radio for $200
Australian dollars and this morning I could not pick up even one
station?

There may be a chance you have a defective receiver. Even during the
middle
of the day you should pick up some stations on the higher frequencies.
When
I was in the Philippines I used to pick up all sorts of stations from all
over Asia & the Pacific.

I have read http://www.geocities.com/n2uhc/portablewire.html and will
give
it a go!

Yeah the guy who put up that site is a pretty neat guy! :-)

what is overload and why do you think Im not getting any stations
When I press auto search it stops at many stations but all I hear is
rumble
noise, if you know what I mean

Overload means your receiver is being overloaded by strong signals, and
this
results in certain stations being heard all over the bands, no matter what
frequency you tune to. Or, it means that strong stations will show up in
places they shouldn't be. Overload is usually a problem with a high gain
antenna or too much amplification. A short wire (15 to 20 feet) connected
to the whip as outlined on my page above should not overload a portable
receiver.

I usually don't use auto search on HF due to the characteristics of
propagation, fading, etc. Plus weak stations will probably be passed
over.
I'm not sure what you mean by a rumble noise, but if the station is strong
and all you hear is rumbling then I'd suspect a defective receiver.

Is it possible, that by "rumbling" he means a loud buzzing from DC to
daylight? If this is the case, I would look at electrical
interference. Likely culprits could include pole-mounted utility
transformers (pole pigs), poorly filtered compressors on AC and
refrigerator units, or any running electric motors.

Steve, you might check around and see if shutting any of these local
things off stops a lot of the "rumbling."

Communist China planning to invade Taiwan in 2012, says highly placed
source: An unnamed "high level CCP official" told the Epoch Times that the
Communist leadership "set up the timeline for attacking Taiwan" early in
2004. The purpose for the invasion of the island democracy will be "to
resolve conflicts inside China, no matter whether Taiwan announce
independence or not." The pieces of the plan were as follows:

Prior to 2008, every policy should center one the Olympics to further arouse
Chinese people's patriotism and prepare for attacking Taiwan. Around 2010,
reorganize the Party and clean out all the members who are against military
action. Around 2012, attack Taiwan and call for an Emergency Act inside
China. Through the Emergency Act, the CCP could confiscate private property,
especially people's savings, to resolve its financial and economic crises.
Eliminate the groups inside China that the CCP deems "anti-government
forces", such as Falun Gong, unofficial churches, human rights activists,
advocates for Tibetan independence, advocates for the independence of
Xinjian (East Turkestan), and intellectuals. Arouse Chinese people's
patriotism through the Emergency Act in order to resolve the unemployment
issue.

The aforementioned anonymous cadre fears "all these steps means China is
closer to fascism." This source specifically cited the newly minted
"anti-secession law" as part of the plot to "give the right of calling for
military actions to the CCP chairman." That man is now Hu Jintao, who at the
time of the plans formation was Vice-Chairman of the all-important Party
Central Military Commission Chairman. Jiang Zemin, who as Party CMC Chair
led the early 2004 discussion that led to the invasion plan, reportedly told
Hu earlier this month, "if we have to attack Taiwan, the earlier the
better."

Communist China wants to limit American weapons in space: Communist China is
calling for a treaty to limit arms in space, in reaction to U.S. efforts to
protect its satellites orbiting the globe (Washington Post). What the
Communists don't tell the paper is their desire to have a clear shot at
those very satellites in the event of a conflict.
http://www.washingtonpost.com/wp-dyn...2005Mar28.html

Communist media crackdown expands:
The Communist crackdown on media continues, with "warnings to three
newspapers: the China Business News of Shanghai, the Economic Observer of
Beijing, and the 21st Century Business Herald of Guangzhou" (Epoch Times) as
well as Nan Fang Daily in Guangdong. To ensure their warnings are followed,
"When the Propaganda Department finds fault with a reporter, editor, or
supervisor, the Department also withholds several months of the individual's
pay."
http://www.theepochtimes.com/news/5-3-29/27444.html

Professor fired for ripping Communist media control: Meanwhile, Beijing
University Professor Jiao Guobiao has been fired for "an astonishingly bold
paper" he wrote last year "attacking the Communist Party's propaganda
department." Jiao "accused it of sheltering corrupt officials and compared
the state censors to those in Nazi Germany." Prior to getting canned, his
books had already been banned, and "he was included in a blacklist of
intellectuals forbidden from appearing in the media."

Are there any government or Military installations or bases or big radar
domes or big towers near you? I am only guessing,but that could have
something to do with causing your radio recpetion problem.

Taiwan is not and never has been part of China.Taiwan is an Independent
Nation.

It would help to understand 3 things with regard to
the above......

1) The Epoch Times is a newspaper which is allegedly
owned by Sun Myung Moon's Unification Church.
A quasi church cult which is known for far right wing
political leanings.

2) The notion that China would invade Taiwan is just so much pablumous
bullshi+.
Taiwan currently farms out close to 70% of it's vast consumer products
manufacturing base to China. This cross-border trade accounts for close
to $800B
in shared revenue. From an economic standpoint, Mainland China and
Taiwan are already one and the same Country/Political Jurisdiction.
For China to invade Taiwan would be shooting themselves in the foot and
killing
one-Half of the Golden Goose that lays the Economic Eggs. (Hong Kong
being
the other half of this equation.

3) China going to war would destabilize the economy of Japan as many
Japanese
companies do business in China. So does the USA. China goes to war
means
no product shipped from the Pacific Rim. The Banking and Merchant
Trade
Guild will NEVER let this happen.....PERIOD.

(Mrs) That's what I was sort of kind of trying to say too,if China tries
to take over (OK,you said it first and I give you credit for that too)
Taiwan,China will **** up big time! I am fixin to put on my cleanest
dirty clothes now and head on over to the Goodwill thriftstore and see
what kind of junk is over there that I don't need and flirt with them
wimmins over there and yesterday,I saw a certain IBM computer over there
and I wont give them more than five dollars for that IBM
computer,assuming it's still there,that is, and I might,just might see a
GE super radio over there that I can buy for a couple of dollars and
sell it on ebay for one hundred dollars or more.Let me get my ass out
the door now.
