Up to 2230 no missed segmenst

a_van_belle
 

Very quiet on the list, is everyone watching TV on HotBird now ?

Today I had no missing segments up to 2230

But I do see a lot of late segments in the report and somehow I miss
image HRIT ch09 0830.

Checking your MSG system on a second signal source

a_van_belle
 

A lot of members are having MSG reception trouble at the moment. Looks like
part of these problems are caused by Eumetsat, but others not.
Yesterday I installed a DVB viewer on my receive PC.
This way you can watch TV and judge from a second source if your antenna,
skystar and PC are working correctly.
Viewing DVB does ask for more performance, so it will detect if your PC's
performance is to low for MSG.
I fully tested this program on my W2K PC were I installed the official
Eumetsat CDROM.
ProgDVB and Tellique do not interfere, but cannot be used simultaneously of
course.
Only drawback: after exiting ProgDVB you have to reboot before starting
Tellique again, I guess some buffers or memory addresses might not be
released.
In the files area I uploaded a PDF manual on how to install and setup this
program.

Using this prog I can view Sailing Channel without any blips, freezes or
missing pixels.

You can download the program from:
http://www.progdvb.com/download/history/ProgDVB4.07FullInstall.exe
Please do not use other versions as I have not tested these.

Greetings,
Arne van Belle

Peter, the 0600 channel 12 segment 14 is not shown as missing here.

Re: Lateral thinking

Don't worry, I have disabled all events that I can find. I was merely
pointing out that the defaults for Norton Live Update and other non-obvious
services can be unexpectedly frequent. I run nothing that I don't need or
want to run which is probably why my system is on a par with a 2 PC system.
What I am concerned about are those events that I haven't identified yet
that might a high load on the system at regular intervals - task manager
doesn't allow me to spot those. These could also affect a 2 PC system.

With a number of non-synchronous repetitive processes, there is bound to be
a time when they all coincide, perhaps overloading the system for a brief
period in time.

Does anyone know what the various timeouts on Windows background services
are and what can be shut down without damage to the basic system?

EUMETSAT do monitor for missing segments and they run (I understand)
both similar systems to ourselves and Unix-based monitoring
systems. They do see the occasional missing segments (the same that
we all see), but not the very high segment loss that a minority of
this group have reported (I believe). Sorry if this sounds like
guesswork but I am not based in Darmstadt!

Re: Missing segments

Robert Moore
 

Dear Dave M. and Dave C.
I only get the full Sun between April and mid-September. From now to late March
I will only see the Sun at the bottom of the garden. I'm on a north-facing
slope with high tress to the south, there is a shallow dip in the tree- line
around south which enables me to line up an HRPT dish until late October. The
_only_ line I have on Hotbird is from the place I have my dish. The erector
even tried the top of the chimney, to no avail. The bottom of the garden would
be unsuitable for various reasons including obstruction by my own trees. In my
current 'slot' I have about 5 degrees clearance over the trees.
The mounting pole is on brackets but it is also braced back against the wall
with a five-foot metal pole to give a rigid triangular structure.
The other 'side of the trees' is over the road, half a mile up a hill, through
the woods and the garden of another house. So some of us have no option but to
go high!
What we do for our hobby - anything but chop down trees (or move house)!
Let's wait and see if there is something other than the inadequacies of our
mountings before we (I) start climbing ladders. Plainly a lot of us are
currently having problems. Has anyone kept count of how many of us are still
having serious segment losses?

Robert



Quoting Dave Martin <Dave.Martin@...>:


and to reinforce Dave C's comments -

Our farmhouse has a shelter-belt of trees, and I was loathe to mount a dish
high on the house, so beyond the trees I have a 1.2m dish =at ground level=
on a substantial mount with lots of concrete ballast

As part of monitoring experiments, in the style of a mirror galvanometer, I
affixed a laser diode module to the rim of the dish projected onto a board
and pencil-tracked the deflection - a "good" gale only gave about 15
arc-seconds of movement of the dish

The second hand Channel Master dish I'm using for MSG has good
rib-reinforcement, but the 1m pressed steel dish I was using for Met-7, even
when mounted on a solid steam-pipe mounting, had noticeable flex and I
resorted to a number of wooden struts self-tappered at the rim and running
back/down to the ground to stabilise the rim. Before I stabilised it, I
could see the equivalent of a couple of degrees movement in a good storm !

Also, don't be afraid of a long lead-in with about an 85m (eighty five metre)
of CT100 lead into the house.

Re: Missing segments

Trevor Davies <g0jix@...>
 

Hi

The mystery deepens!

I bought my 88cm dish from Timestep in March 03.
It is mounted at ground level on a metal tube and anchored to the wooden garden fence to limit lateral movement.
It was installed early April using the Status facility in Set4PC to obtain maximum Signal quality,which can vary from 60% - 70%,SNR 9.7 - 10.8 and BER all 0000,s and no ill affect on imagery in any way.
It has not been altered since day one.
I have posted a photo at http://photos.groups.yahoo.com/group/MSG-1/lst titled 'Dishview.jpg' This is the view my dish has and I think it can be said it is not ideal,prior to this photo the trees carried a lot more foliage.
I have,judging from the mail,had results comparable with many and far better than others
I'm not sure this helps,but may save some from premature baldness.

Lateral thinking

Roger Mawhinney <roger@...>
 

We seem to be missing something here.

I've been running a single PC system (Athlon 2200+, 1Gb memory, Raid 0
disks, XP Pro) and never really checked missing segments assuming that I
would naturally miss a lot more than the dedicated 2 PC systems. However,
over the past few days, I've realised that I'm probably on a par with most
users. I'm currently running MSGDataManager, Outlook, Norton Anti-virus,
Office Indexing, Defrag, Climate Prediction and probably a load of other
junk I don't even realise. When I use the PC it's for mostly really serious
Photoshop work as well as the background remote imaging, yet I do not feel I
am seriously disadvantaged in terms of quality and lost segments. Why not?

If it's not the PC, what else would cause serious segment loss? Is it
Eumetsat? Do they give any statistics as to lost or delayed segments?
Perhaps it is time for a bit more investigation away from the obvious over
loaded PC.

You just can't believe specifications, it probably says +/- 1dB somewhere,
or if not, what is the tolerance ? And anyway, manufactures have been known
to just invent figures, who can prove them wrong, or right ?

Yes, that was the way I read it as well. I just didn't want to
think that the card I had just replaced was actually better than its
replacement! Presumably this means that you need at least 1dB
greater SNR with the newer card (or USB version) than with the older
card for the same performance. Perhaps it isn't that simple....
