Hello Johan,

Your equipment is well suited for this job.
Try to install ProgDVB and tune to Kurdsat.
This digital TV channel is on the same transponder (=downlink
frequency) as EUMETCast, only uses another PID.
You should be able to enjoy image and sound without interruptions
or "freezes".

Hello Ian and Douglas, the Internet is just two clicks away (or was

first. Could be waving trees or a wobbly mount.

99% signal quality does not mean a lot, as we have seen before it
depends totally on Card version (2.3/2.6/USB BOX) and used driver
version.
We have also noticed that the signal bar is averaged/delayed and

does

not show fast fading signals due to a dish wobbling in the wind.

A local interference on the IF at 1346 MHz could theoretically

ruin a

good reception but is hard to detect without sophisticated

equipment.

If a second receiver does show good steady TV signals on Hotbird,

it

is time to install ProgDVB (using the doc I uploaded to the files
area) to see if the PC can cope with the high data rate for longer
periods.
A faulty PCI Bus/card or rogue driver can cause DMA or IRQ

conflicts

that disrupts the data stream intermittently.

Johan, to rule out some know problems can you give us some details

on

your PC? (Windows version, CPU speed, Memory)

David,

I am maybe being a little unfair in that I only run Met 8 from about 08.00
to about 22.00 UTC and not 24 hours. I did lose the 17.00 ch 10 seg.8 on
5/3/04 but that was reported by Eumetsat and in the 14 hours per day that I
am running I have not appeared to lose a segment at this end since
installing the updated drivers. Having said that my Athlon 1200 has been
struggling recently with multi-tasking ( particularly dial-up ) although
that is probably not surprising. However that should be resolved soon with
upgraded computer although I have still to decide about networking.You and I
know however that an expert on that subject lives some 55 miles from me and
I am sure I could persuade him to assist me in networking XP Home and XP
Professional !!!!!

Not been in touch yet with Eumetsat. The mail situation has been horrendous
here last week ( with Freeserve) but it looks like it is getting back to
normal today, so will send off a mail this week.

Regards

Ian.

David,

Might not be. I am now using the latest DVB drivers 4.2.8 and in

clear conditions my signal quality also sits at 99%. Also have to
say that I have not lost one segment in the four weeks that I have
been using these drivers even with this low spec. computer.

How about:

2004 Mar 05 0400 HRIT ch 10 seg 3, 1700 ch 10 seg 8
2004 Mar 06 0730 HRIT ch12 seg 11

I think both Arne and I missed those....

However although paid for well over 4 weeks ago, I have still not

received my EKU and that will be the real test for the updated
drivers. It is likely however that my new computer will have arrived
before the EKU and that will be even more interesting ( Athlon 64
3200 ) --- that will give Tellique a fright !!!

Regards

Ian

Yes, it was the real test for me - but I don't see many reports of
problems here. I presume you are in touch with Eumetsat - four
weeks sounds like a long time - but you do have until mid-April so
no panic quite yet.

Cheers,
David

You're right David,

If the Setup4PC icon is changing colour, Tellique won't be able to
make any sense of it.
Johan send me a TQ log directly and it does only show a lot of
disconnections and lost messages.
The problem is that he had his dish and cabling installed by a
company. Johan will have to prove (by viewing a TV station) that
there is somthing faulty in the setup.

I also had a "professional" installation (please don't laugh) and I
found that the signal was lower than I remembered from the first
time the system was installed. The signal level also varied a lot
in the wind. I concluded that the dish alignment had altered, and I
got the installers back to correct the alignment. This was about
six months after the first install, and they did the re-alignment
free of charge.

If receiving a TV station on your PC does not work, I think what you
need is a satellite TV Box, and try plugging the cable from the dish
into that. Will prove if the LNB, cable and dish are OK.

Can you remind me if the installation has ever worked correctly?

CHeers,
David

Arne, thanks for your advice. The way I read Johan's message was
that it was the Server4PC icon that was changing from red to green -
so what would you expect to see in the Tellique log file? I believe
Joahn's system used to work, so I would ask:

- when did it work?
- when did it stop?
- what changed in between?

I think the only time I saw the red/green colour change was when I
had the two PCs driving the LNB in different ways - by accident.
One trying to set hi-band and the other lo-band (or a conflict over
polarisation).

Cheers,
David

Is it normal for hurricanes (such as the one currently near
Madagascar) to show through quite so much on the water-vapour
channel? Is so, why?

Thanks for the reply David. Just pasting from the web address.

At the moment yesterday morning's mails are just coming in !!
Freeserve have now admitted to a problem but their web site says
some mails are up to 40mins late !.....that should be hours !

I had one that was about 30 hours....

Back to topic. Got you now. I thought perhaps it was a GSS4

option I had missed ! No I think better as delivered from the
satellite with some image enhancement according to time of day. I
am still surprised at the channel 4 response considering how close
(in wavelength) it is to the AVHRR channel 3B.

Thanks - I found channel 1 had the highest visibility of the dust.

I am hoping to find out more from that new Eumetsat web page I

mentioned in my mail yesterday with hundreds of Mb's of downloads.
Talk about educational....it's superb and I have only looked at a
tiny fraction of the downloads.

Thanks again.
Douglas.

It says you can ask for them on CD - for those who don't have the
bandwidth, by the way.... I looked at the 30-minute/5-minute
animation comparison - remarkable!

You will have noted that your comments on the dust triggered me into
action!

Cheers,
David

However you have caught me here in that I am not sure how I create
the ''visible'' element setting to which you refer, or at least
using GSS4. Could you please put me out my misery. (with apologies
for delayed responses due to protracted method of working at the
moment).

Regards
Douglas.

I just meant do you use the channel 4 image as delivered from the
MSG Data Manager (black is hot - like a thermal image) or is the
dust more visible if you mage a negative of the image, and view it
like a visible channel image (white is hot, i.e. more radiance is
white).

David

Credits go to Douglas who pointed us to the dust storm that is
heading out of the Western Sahara at this moment.

I did a GeoSatSignal job using Meteosat-8 Ch1, Ch2 and Ch3 data,
composing a stunning colour animation of this huge dust storm that

heads out to the Atlantic Ocean. The dust movements actually
started on March 03 but its effects are most visible on March 04 and
today.

On today's animation you see the dust already reaching
Spain/Portugal. In the wake of the Cape Verde Islands you can see
some Karman vortices in the dust.

I followed Arne's instructions and made an animation, although I
used a smaller image size to help reduce the file size. I then used
JASC's Animation Shop to convert the movie into MP4 format which
ended up as being a 5MB file. You can download the movie from:

ftp://ftp.blueyonder.co.uk/store1/incoming/2004-03-05-Sahara-dust-
mp4.avi

(beware any wrap...)

I also uploaded another couple of animations showing cyclone Gafilo
just off Madagascar, in both visible and IR fomats. Both animations
are about 5MB in size.
