I apologise. When you said in your original survey request :-

"EUMETSAT are very grateful for the technical feedback you are providing."
"Oh, and are you a RIG member?"

Naturally, and this was my mistake, I thought you were involving Eumetsat
and RIG in this. I didn't realise it was a personal survey to help you as
an individual decide how to get going on MSG via Hotbird.

So my advice, and even more so now John, is to get a single computer system
running in your home. And let us know how you get on with it.

Dave,

Thank you for your response.

Well, not exactly 'personal' and to help just me but, though I'm not
operational,
I think (hope) I'm fairly well informed but there are things I don't know
about
'operating' (from a computer point of view) a receiving system.

If that is the case with me, then some of our members - or potential users
are
going to be even more 'confused' and intimidated.

We know the spec. that EUMETSAT put out and many will have looked at that
and said 'forget it.'
But it has been proved that lesser and in some cases much lesser spec.
systems
will 'work.'

I thought it would be interesting and useful information to get some idea of
what
systems are in use.
It seems a beginners guide is not viable?
And a FAQ's document might also not be easy due to varying wants and systems?

How it will all end up remains to be seen.
It might just end up being an interesting exercise but I hope it will be of
use to those
who don't have much idea of what is required - you know, they come along to
the
stand and say 'what do I need - and how much will it cost.'

Also, it's interesting (to me anyway) that some users have had no problems
and
others have had several problems.

Anyway.

Regards,
John.

20.00 scan, HRV segments 8 & 9 missing and data gap on other

agreed the same here.
No I/O error on the 17.40 as far as I know.
Thnaks for the report, Douglas. MSG-1 data seems to have stopped at
21:39, although Foreign Satellite Data (and Admin messages) are
still flowing.

Subject: [MSG-1] Data gap tonight


Folks,

I seemed to get a data gap in my Tellique log tonight around 20:08
UTC, in between:

20:08:45.717:Disconnect from data channel `EUMETSAT Data Channel 2

and

20:10:06.353:Received new key 43993

(Tellique log file entries)

This seemed to co-incide approximately with segments 8 and 9 being
missing from the HRV image, and a data gap on the other channels. I
say data gap because the program shows no missing segments, and the
visible gap is not exactly 464 lines high. Did anyone else see this
or do I have a local problem?

Also, did anyone get an I/O error 103 around 1740 UTC today?

Thanks,
David

I have just got up and running with MSG data in the last few days and I feel
it is worth sharing a few points that might be of assistance particularly to
anyone considering going ahead.
I went the Eumetsat route for the Tellique software and I have to say that
their service was superb. From the day I submitted my application to payment
and receiving software I was kept informed by e-mail and all was completed
fast and efficiently.
It would appear that there has been some minor updates to the Tellique
software. For example when I switch on my computer the data starts to load
in automatically without me needing to do anything ( in start up ) except
for starting Data Manager.

A number of mails over the last few months have discussed systems, problems,
over heating and other issues, so I don't want to bore you with more facts.
However I will just say this. The card worked first time without the

PC requirements - comparison of single and dual systems.

David J Taylor GM8ARV 🏴󠁧󠁢󠁳󠁣󠁴󠁿 🇪🇺
 

I recently had chance to compare some results with Sam Elsdon who
commented about disk activity on a single PC system during
animation. We compared results when not running animation - my
system just running MSG Data Manager, and Sam's running the Tellique
software as well. Measurements done with the Windows Performance
Monitor. Thanks to Sam for sharing his results.

Dual PC setup:

% Disk Time: 1-2%
Average disk bytes per transfer: 10KB
Disk transfers per second: 5

Single PC setup:

% Disk Time: 9%
Average disk bytes per transfer: 33KB
Disk transfers per second: 150

Now this isn't a scientific comparison on two identical PCs with two
identical operating systems, memory, or disks. However, 150 disk
I/Os per second is massive! One disk I/O every six milliseconds.
Both a small cluster size and lack of regular defragmentation could
cause this result, but having to handle all the temporary I/O for
the Tellique software, plus writing and reading 8 segment files to
and from disk instead of one network transfer must contributes as
well.

My recommendation would be that, if you must use a single PC system,
be prepared to tune that system carefully for best operation.

Comments welcomed.

Cheers,
David

I don't know what your quest is here. Sam and I both run animation on a
single computer, and we could run several computers if we wanted to. We
choose to use one computer.

John, could it be, that you are still not receiving MSG at all ? In which
case why don't you telephone Sam or me, or even fellow RIG committee member
Mark Clark for some one to one assistance ?

Dear MSG-1 user group.

Presumably a slip of the finger?

All,

I have never said nor suggested that the MSG equipment survey I am
undertaking
is being done for EUMETSAT - OR RIG for that matter!

It is entirely due to my own initiative and my somewhat of a lack of detailed
technical
knowledge in some areas - which some users posses - and the hope that
information supplied by users may be of use or value to others that prompted me to
take this on.

I've no doubt EUMETSAT will be interested to know what users are using as a
receiving systems - as they are in the valuable feedback amateurs are
currently
providing on this new service.

Your best bet, bearing in mind who you are, is to adopt my and David
Taylor's suggestion, start with one computer, sooner rather than later ! (?)
And what's that supposed to mean - 'bearing in mind who you are'?

Re: Solar outages to be expected on MSG-1 next weeks

johnrigsec@...
 

Arne,

You beat me to it!

In fact there will be two losses of data due to sun, satellite co-liniarity.
The first 'outage' will be when the sun and users Hot Bird 6 receiving dish
are
co-aligned.

The second outage will be when the sun, MSG-1 and EUMETSAT's ground
station are co-aligned.

John Tellick.

Did you REALLY mean you are unaware of Geosatsignal John? Or are you

overlays of Bracknell charts, temperature calibration read out, zoom in

I think David might let you have a trial license if you want to dip your

Hello James,

It's OK, I've had my wrists slapped by David when I phoned him.

No, knowing there was an animator with MDM now I wondered why people might
want to use Geosatsignal.
But I am now aware thanks to David and yourself that you can do so much more
with it.
It certainly sounds quite amazing.

I'll get there in the end - promise.

Thanks for explaining the animation differences.

Most TVsat installers will confirm that a burst cap due to solar
outage is a common problem around this time of year!

Arne, I have seen these split caps and have wondered what caused them. Thanks for the warnings, I can always throw some cover over the LNB. More likely than not, the sun just won't shine!!

Hello Alan,

You're partly right Alan, TV dishes do suffer from the same effects.
But there won't be many TV viewers watching around 11:00 UTC. And
before they know what is happening, the solar outage will be over.
But MSG "viewers" might miss multiple images and unnecessarily start
checking their equipment or blaming Eumetsat!

About damage to LNB's: As I said, only in exceptional cases damage
could occur because modern dishes have a rough, structured surface to
prevent reflecting too much sun and LNB's have a sturdy cap. But this
won't be of any help if your dish is covered by ice. What are the
chances of rain, followed by a frosty night and a sunny morning in
early October ?
Let's hope we don't have these conditions!

Most TVsat installers will confirm that a burst cap due to solar
outage is a common problem around this time of year!

Arne van Belle
