Hi all,
Does anyone experiment troubles listening to Asiasat 3 ?
The problem is that for a week now and everyday at the same time
12H05
to
12H20 (during the News !!!) I get the No Signal message on the screen
with
every channels on Asiasat 3.
All the others satellites - from 65 Deg (Pas 10) to 152 Deg (optus) -
are
sending the signal normally and I can get them.

I checked the antenna and notice it aim right to the sun at that
time,
so
I
can only suppose that the sun interfere with the micro waves sent by
the
satellite.
Does anyone knows a way to solve the problem? and why does it happen
now
? -
I never had it - do I have to readjust the antenna?
Puzzled !?!
Any info is welcome and thanks.
John & Su.

Don't panic at this time of the year for around 1 week there will be
solar
outage at certain times of the day. The outages should stop
eventually..

Thanks for the info.
I do not panic but I was thinking my antenna wasn't anymore on the right
direction or rats get dessert with the cable under the roof!!
Perhaps you can answer this question :
Does the satellites have the same orbit that the sun or are they a little
bit moved forward ?

Sun Outage
Each Spring and Fall, cable companies experience a technical phenomenon
called "sun outages." For a period of about 2 weeks, the sun causes "solar
interference" to all geostationary satellite signals. As the sun's path
across the sky gets lower each day, there are times when it is in a direct
line behind a communication satellite that is sending signals to a
receiving
satellite dish here on earth. When the dish antenna is looking into the
sun,
the interference from the sun overrides the signals from the satellite.
This
is when a sun outage occurs.

Sun outages typically occur during the months of February/March and
September/October and can last as long as 15 minutes a day and take place
over a period of 15 days. The effects of a sun outage vary in degree from
minimal to total outage throughout the 15 day period. Once it reaches its
peak, the interference will gradually decrease becoming less noticeable
each
day after.

Unfortunately, there is technically nothing we can do to prevent sun
outages
from occurring. Each satellite service that we receive signals from will
experience this interference at predictable times.

I wonder...
... since each satellite will experience interference at predictable times,
if they could coordinate switching to less affected satellites as the period
passes ...
or ..... is it that they all experience interference in so small a time
window that it would make switching pointless...
Of course the cost of switching could be a big factor even if it is
possible.
Do you know about that Khun Craig?
