My understanding is that DRM on Shortwave acts just like IBOC on AM,
with adjacent-channel interference. Is this true, and has anyone
noticed sideband interference coming out of 9800 Sackville? I picked
up Radio Canada International today, and did not notice interference
from them...

I have and it usually covers at least 3 channels. It is stupid to have
stations operate in the SW broadcast bands in this mode.

Are you refering to the DRM signal interfering with adjacent analog
transmissions or the other way around?

The fate of the moon in the Holy Quran and science

By Magdy Abd AL-Shafy

I would be thankful if you give my article 5 minute of your
value time. THANK YOU


Modern astrophysics , depending on accurate calculations , says that
both the moon and the sun will be joined someday . The Holy Quran , in
reference to the Doomsday , stresses the same fact .



Here is an article from Nasa that explains how all it will begin : the
study says " Our Sun is made up of more than billions and billons of
tons of matter. As a result, all of that matter produces a huge amount
of gravitational force that squeezes the star more and more inward. In
order to combat the inward crush from the gravitational force, The
Sunutilizes fusion power to hold themselves up. At the Sun’s core,
where the crush is most extreme, Hydrogen nuclei are repeatedly pushed
together and combined to form Helium. A small amount of energy is
given up in these fusion reactions. The newly formed energy flows
outward toward the Sun’s surface heating the outer layers in the
process and puffing the Sun up to counteract the inward force of
gravity. According to scientists, as long as the Hydrogen fusion
reactions are functioning as they have in the past, the Sun is safe
from gravity and can continue to serve as a source of heat and light
for Earth. Unfortunately, the hydrogen fuel of the Sun can’t last
forever. All good things eventually come to an end. In approximately
five billion years from now, the Hydrogen at the center of the Sun
will all be converted to Helium. At this point, the Sun will begin
die. The Holy Quran refers to this stage in the life of the sun , God
says in the Holy Quran what means " When the sun (with its spacious
light) is folded up " [81: 1]This is a matchless ****phor for causing
the sun to lose its light. Takwir means to fold up; hence takwir al-
`amamah for folding up the turban on the head. Here, the light which
radiates from the sun and spreads throughout the solar system has been
likened to the turban and it has been said that on the Resurrection
Day the turban will be folded up about the sun and its radiation will
fade. Many Astronomers also believe that this will also start the
beginning of trouble on our planet. Without its Hydrogen, the Sun has
to find an alternate way to free up energy and combat gravity. The
Helium deposits in its core can be fused into Carbon and Oxygen, but
only if the conditions in The Sun’s core become much more extreme. In
order for this to happen, the Sun changes in a very radical way. The
core contracts and, even more importantly, the outer layers swell.
When the Sun reaches its maturity, it will begin to bloat and swallow
all the inner planets including the moon .

Another scientists says " The Sun is midway through its stable
hydrogen burning phase known as the main sequence. But when the Sun
enters the red giant phase in around 5 billion years things are going
to get a lot rougher in the Earth-Moon system. "During the red giant
phase the Sun will swell until its distended atmosphere reaches out to
envelop the Earth and Moon


The Holy Quran refers to this stage in the following Holy Verse ; God
says in the Holy Quran what means " And the sun and moon are joined
together," Joined together ….doesn’t science say that ? Yes , it does
…..so who told Mohummed …..He must be God , the creator of the
universe …….it must be God who knows all the secrets of the universe …
SO the Holy Quran is surely a Divine Book . When the moon is so close
to the sun , the outer crust will expand and broke into pieces ,
exactly like when the earth when undergoes an earth quake . The Holy
quran mentions this stage in the following verse "When the planets are
scattered" It is scientifically known that the stars are planets .

The moon is moving towards the sun


How was the moon near to the earth billions of years ago billion years
ago, the Moon was much closer to Earth than it will be tonight. Its
tighter orbit meant it needed just 20 days to go around us, to make a
lunar month. Other things were noticeably different, too. A day on
Earth back then was only 18 hours long.

The Moon is now moving away from Earth and by then will be in an orbit
that’s about 40 percent larger than today. It will be the first to
warp under the Sun’s influence. Today, the Moon is on average 239,000
miles (385,000 kilometres) away and has reached this point after a
long and dramatic journey. How far does the moon go every year ? The
Moon is being pushed away from Earth by 1.6 inches (4 centimeters) per
year and our planet’s rotation is slowing. So the further the moon
goes , the less its light till it meets the welloen atmosphere of the
sun . The Holy Quran mention this scientific fact which implies that
the moon is moving away from the earth ." And the moon is buried in
darkness. " [ AL-Kayma :8] The moon will move away from the earth till
it meets with the swollen sun ,thus collected or joined with the sun
Unspeakable events will happen before the doomsday . Further , Quran
tells us that the sun will attract or swallow the moon ; God says in
the Holy Quran what means " And the sun and moon are joined together
" [ AL-Kayma :8]


it is literally says that both the sun and the moon will be joined
together . Numeric miracle : Astrophysics says that the moon and the
sun are aligned (19) times in the year ; the word the moon and the sun
are coupled or mentioned together(19) times . Though scientists
calculate the period of cosmos events by millions and even billions of
years , we would like to say that these are theoretical calculations .
God has created certain laws that we don’t understand , An
astrophysics says , likening the human knowledge of present scientists
as those of kids in kindergarten . this means that human mind hasn’t
got every thing . God says in the holy quran what means " of knowledge
it is only a little that is communicated to you, (O men) [ Al-Asra :
84] We want to say that such calculations may happen because of the
other laws that we don’t know . Any way there is a conformity between
what science and the Holy Quran says



In the intervening eons, the Moon has been drifting away. Each year,
it moves about 1.6 inches (4 centimeters) farther intspace.

Can be a coincidence that such accurate facts in the holy Quran be in
conformity with the newly discovered scientific facts ? If Mohummed is
imposter , why did he leave the culture of his age ,though he received
no culture . He could have won many people on his part , if he had
mentioned the culture of his age . Who told him such highly scientific
facts that highly qualified scientists ,after long –tiring search ,
came to? There is no doubt that Quran must be God’s word , who says in
the Holy Quran what means " Should He not know, He that created? And
He is the One that understands the finest mysteries (and) is well
acquainted (with them). ( Al-Malek :14) What do you still in need to
believe ? What evidence do you still in need to believe ? What can be
called the unseen is turning to be seen You are running out of time ,
once the story of your life comes to an end , there will either
permanent happiness or eternal perdition . It is time to win yourself
"And He found thee wandering, and He gave thee guidance." The word
wandering is not an accurate translation , the word (Dala=wandering "
has another meaning , it is the intended meaning , it means (loving )
In Arabic , excessive love makes the human wander aimlessly , nothing
here or there to attract his attention but his beloved – that is the
case with some Sufis Abu-Alyazedd, once filled the ecstasy of love
towards god , so he wanderd till he entered into a field of
sugarcane , already harvested , so the rest of remained as knives in
the field , he walked on them , not feeling , his leg were severely
wounded and bled so much , he was wandering not feeling of what
happened –he bled all his blood till he died . This what happen when
God manifests himself partly to the human heart Remember what happen
to the mountain when God manifested Himself Also , remember when in
Journey nigh the angel stopped at a certain point no able to move , he
won’t be able to bear the lights of God’s glory –manifestation Only
Mohummed was supplied by another power to bear As to prophet
Mohummed , It is something unknown that was enshrined in his heart ,
this move him to wander , moved him to leave his wife , his tribe ,
all of the world , he left the world to live in a versy small cave in
a very hot desert – for what , the verse answer him saying " we found
you (Dala-wanderer ) and we did guide you.

Are you refering to the DRM signal interfering with adjacent analog
transmissions or the other way around?

DRM is just digital without the analog signal. The digital signal all by
itself covers at least three channels.


I thought that it had a hybrid-mode?

If it does I'm not aware of it.

Yea, doesn't DRM also have digital saddlebags as IBOC?

Digital mode transmission spreads out due to square waves being
composed of odd harmonics. You need at least the first two for a square
wave to have its basic shape and so 1, 3, and the 5th harmonic. For a
square wave that looks very much like you would expect you need
1,3,5,7, and the 9th harmonic, 5 total, so you can maybe get the feel
of how a digital modulated signal needs to spread out occupying a wide
swath of frequencies.

The current scheme to minimize this spread of modulation harmonics IBOC
or DRM is to use multiple carriers switched on and off at an audio
rate. The problem here is that these modulation algorithms are not as
efficient as analog modulation regarding frequency efficiency. This is
one of the dirty secrets of current digital modulation schemes. There
are upsides to using digital mode but you will use up more the
frequency spectrum to get it.

This multiple carrier idea is old technology for either IBOC or DRM.
The only thing remotely new are the algorithms used to digitally encode
the audio before that is applied to the modulation algorithm.

This mix of audio digital encoding and modulation scheme has a tendency
to appear as a random square wave modulation of the carrier, which
completely fills the occupying spectrum used. This creates the
"saddlebags" you mention.

Digital mode is fundamentally incompatible with analog channel
assignments and as such is part and parcel of the folly of mixing
analog and digital modulation modes in the same band. In other words it
is just plain stupid decision making.

Old technology coupled with dumb decisions equals the mess we have to
deal with on a daily basis now on AMBCB and the SW bands.
