Subject: [MSG-1] Packet loss

Hello all,

Since the changeover yesterday I am seeing an increase in packet losses
- resulting in more missed segments and a slowly growing 0.fsy

I have tried the familiar switch off and restart - but to no avail

http://www.meteosat.talktalk.net/mrtg/tellicast-jbmain.html

for anyone who cares to have a look.

Cheers

It's strange, James, but I've been wondering about an increase in packet loss rate on a couple of PCs here as well. I don't /think/ that EUMETSAT have been tightening up on
the tolerances of anything, but you never know. If nothing's changed on the PC, perhaps some Windows or other software updates have crept in?

There are some basic points to check (although I'm sure they are already set on your system):

- remove the [*] entry in recv-channels.ini

- ensure that you have a common tmp_directory set in your recv.ini

- RAMdisk in place and working? Adequately sized?

- mstDefrag installed and running?

- no disks too full

- no unprocessed files clogging directories

The key parameter is signal quality rather than strength or SNR. If the skew on the LNB is wrong, or if there is some cross-polarised signal getting in from the other transponder on the same frequency, this will cause the quality to drop and hence increase the missed packet rate. I'm guessing that the LNB developing oscillator noise could have a similar effect.

Cheers,
David

You seem to be alone in this problem. Its either your location or more
likely something amiss with the dish to PC chain. I'd check all joints
links etc if possible.
Hope you can sort it.

Thanks Alan - it is strange. Looking at my other MRTG graphs signal strength and s/n ratio is unchanged, and no BER to speak of. The receive computer does nothing except process, and has no updates beyond SP3 a long time ago for the XP home Windows version. Perhaps a failing computer somehow...

Meteosat 8 got holed a few years ago resulting in a thermal re-balance and the loss of some redundancy, so it can happen.

From EUMETSAT............................


EUMETCast Meteosat 0 degree Multi-Service News

Issued on 15/08/09 at 10:07:29

Seq Nr: 2

News information:

Due to the triggering of a Meteosat-9 safe mode on 15/08/2009 (day 227) at 05:13 UTC, all Meteosat-9 operational services with the exception of LRIT have been swapped to Meteosat-8 with effect from 09:00 15/08/2009 (day 227), Meteorological products will follow when available.

Investigations into the cause of the safe mode triggering are in progress. Once the cause is understood recovery operations of Meteosat-9 will commence and operational services will be resumed. Further announcements will be made as the investigation proceeds.

During this time users will receive SEVIRI, DCP (except IODC) and Met Products on EUMETCast data channels 2 and 3 with the file name and contents labelled as MSG-1.


.....................................


MSG Data Manager users please follow the procedure here:

May I echo Douglas Deans' thanks to EUMETSAT for such a rapid response.

Cheers,
David

Francisco,

With Meteosat-8 being located at 9.5 degrees East, the coverage to the west will not be the same as Meteosat-9 at 0 degrees. However, it may be worth reporting that to EUMETSAT in case they can adjust the HRV scan limits for better coverage in these unusual conditions. Until then, I hope that the coverage from channels 1 and 2 includes the Canary Islands.

David

.. but if you now switch to MSG-1 in the Advanced setup, stop and restart
the MSG Data Manager, you will once again get zero-degree images. The swap
has been done by EUMETSAT.

Yes I have now changed Data Manager to MSG-1 as the FSD data is now
coming
in with MSG-1 on the files. Looks like MSG-2 has had another of its
safe
shutdowns ( hopefully nothing worse ).

Same status here, folks. It looks as if a changeover is in progress.

BTW: with the MSG Data Manager, there should be no need to change
MSG-2/MSG-1 just for the FSD providing that you have Setup, Channel
selection, FSD, Generic naming checked. Of course, a change and restart
/will/ be required should data from MSG-1 start on the full zero-degree
service channels.

Good luck, EUMETSAT.
Yes indeed. Given that the standby satellite has to be re-commanded (as it
is active on RSS), file names to be changed etc. for all the Eumetcast data,
that it happened at approx. 05.00 on a Saturday morning, Eumetsat staff have
to be congratulated on the switch-over.

Regards
Douglas.

Met-9

Ian Deans
 

Re my last mail I now see that the RSS service has stopped so it is almost certain that Met-8 is to take over as the back-up satellite.

On the Eumetsat site the Met-9 status is red.

Regards
Ian.


Re: Meteosat 9 data stopped...

Ian Deans
 

Yes and I notice now that the service admin. messages coming through are
for MSG-1. They are in my receive folder, as Data Manager will not deal
with them unless I change the satellite setting.

Might be a sign that Met-8 is to be used as the back-up satellite with RSS
stopping. Time will tell.

Regards
Ian.

Re: Ricezione MSG con triplo LNB

a_van_belle
 

Hello Tino,

Yes can receive 9, 13 and 19 East using 3 LNBs in one dish.
But it requires a special bracket as this configuration is not a commonly used one.
Look for one like this: http://www.satelliten-shop.com/catalog/product_info.php?products_id=87

You may have problems with 9 and 13 as these are only 4 degrees apart, this means on a 80 cm dish that the LNB feedhorns will touch if they are large diameter.
To use 1 cable to your PC you need a 4 way disecq switch and setup Technisat and Progdvb for this switch and cannot watch TV and Eumetcast at the same time.

Using SatmasterPro demo version you can calculate the required spacing between the LNBs (using "dual feed spacing" twice).

Greetings,
Arne van Belle

Hello to all. Task of having a problem that is common to many: I have received i data MSG from MeteoSat via HB13 for a beautiful one po' of time with a parabola 80cm with double LNB 13/19 + card SS2: all ok (to part some problemino begins them of setup all e' gone ok). Now that e' passed du to Eurobird9 my question e' the following one: I can add a third party lnb to use with EB9 (therefore to arrive to a configuration 9/13/19, centered on 13) and to make to enter in a Diseq to 2 entered cables of lnb 13/19 and dell lnb 9 so as to exit on SS2 with an only one cable with the 3 marks them? I would want to maintain l' lnb it originates them poiche' on the PC of the SS2 I have also ProgDVB x the vision of i channels TV. Thanks dell' aid. Byeeeeee
