Dear Eumetsat
Dear all

Just a big thank you to Eumetsat that managed to improve the EumetCast uplink chain that gave us a couple of simultaneous lost packets all over Europe in the past. This effect seems to be gone since mid January 2011 about when I installed 2 APC Smart UPS for my EumetCast receivers.

An here comes the publicity part: For the last 100 days both my GNU/Linux receivers have not lost a single packet. So another thank you to the community that keeps up making and improving Free Software.

Cheers
Ernst

See http://www.gymalp.ch/~eumetcast receiver links at the bottom.

I had not realised that once you get the red T, that reception was
permanently stopped. If the RF level and frequency still look to be
correct, it could be a network issue - check with a PING 192.168.238.238.

Thank you this ping tip. I will check it in the next red T occasion.

On an 80cm dish here I see about 63% quality, and 8.3dB SNR. Your 54-57%
sounds a little low (as does mine), and you can compare with others here:

I have just a small dish, because the old bigger one was broken by stormy wind. (and I have also a stupidly set extension cable which obviously decrease the signal quality.) Anyway. It is working OK.

Looks like your mail may have done the trick.

Thanks

I sent an e-mail to ops at the back end of last week concerning the
absence of MODIS files - had a reply with a query from them this
morning. I checked and I noticed a few descending pass files came in
about 0300 - but nothing else. Can I take it that I am not alone?

Hello Ian,

Yes I had a reply when I got back in today:

'We had a problem with the server over the weekend, the server has now
been restarted and the files are flowing.'

Still no filter on the out of area files though.

Cheers

Here are my statistics (in a few hours period):

Received Packets on Data Channel: 1653936
Missed Packets before FEC: 40
FEC Recovered Packets: 31
Received Bytes on Data Channel: 1934612000

So I have some missed packets, but otherwise I have not experienced problems with the received images (at least with those ones which I regularly checks) (until T goes red, because from that time no more received file.)
I have 54-57% signal quality in setup4pc.

Korn�l,

Difficult to make a judgement - if that was a receive-only system running XP then I would expect zero missing packets, but my dual-core Vista system with the DVB World box gets about 10 missed and 10 recovered per day. I had not realised that once you get the red T, that reception was permanently stopped. If the RF level and frequency still look to be correct, it could be a network issue - check with a PING 192.168.238.238.

My recent files appear to have ended with:

Dear All, David,

I checked my tellicast log file. these are the last lines:

[]

MSG:2011-04-25 18:35:00.427:Channel "TSL Announcement Channel": Lost message 1367134 (message lost)

.
.

MSG:2011-04-25 18:35:02.721:Channel "TSL Announcement Channel": Lost message 1367143 (message lost)

[]

Another important symptom is that although setup4pc icon is green, its Tranponder Information says: "Network: No Information" instead of "Media network".

Only complete computer restart helps.


Thanks for your Reply!
Korn�l Koll�th

Korn�l,

I recall that when running Setup4PC a second or third time it may not show network information, I would not worry about this.

When you look at the TelliCast HTML shell, Statistics, do you see:

Missed Packets before FEC: 0
FEC Recovered Packets: 0

If you don't have zero packet loss (or at least all missed packets recovered), then you will get missed data, and hence the "message lost" reports. Getting missed packets down to zero can be more of an art than a science, and entails careful configuration of your PC.

Cheers,
David

Help, Index, Command-line operation

As always, blind for the obvious. My wife is sooo right :)

Thanks, cheers,

U.

If my memory serves me right (well, yes, if...), I once saw a descripton of
what command line parameters are available for MSG Manager. The text
file that comes with the package does not disclose that, and a look at the
relating webpage did not really teach me more here. Where have I put it? :)

I guess, -START will do what it says, like for the METOP Manager, or? And
are there any more?

TIA,

Cheers,
U.

Hello John and David,

Even with all software up to date, it is recommended to check your received folder at least once a week.
There are so many data selection options in MSG data manager, you can easily have overlooked one.
And we occasionally see new or trial products accumulate here.

About your temp files, these are failed attempts to compose a file from the FSY files. No space left on your hard disk could also cause this.

Greetings,
Arne van Belle

Actually, with recent versions of the MSG Data Manager there is an option to automatically remove unprocessed files from your &#92;received&#92; tree. On the Setup tab, Options, File controls, RX disk space control, just select a non-zero value for Auto-clean minutes. I would suggest a value of 480 (8 hours) for folk who run on a daily basis, and perhaps 1440 minutes for those on 24 hours a day. The Tools, Housekeeping report menu has display where activity from this option can be seen in the lower panel.

You can also my TrimTree program to clear out many directory trees on the basis of "delete files older than N days" - it's a free (but unsupported) program available here:

http://www.satsignal.eu/software/disk.html#TrimTree

Add it to your night job or login job.

Cheers,
David

All,

Having experienced several gaps in HRIT and AVHRR data this afternoon I
'went looking' and found low Ramdisk capacity - which is usually a suspect.
But also I found a rather large received folder - 733 MB's.
And the temp folder full of empty and 'filled' files.

The files in question in my received folder were:

L-000-MSG2_-MPEF_____-FIRC____000001 plus a date.

These seem to have accumulated since March.

In my temp folder there are many files such as:

4c8fc .....
4c922b .....

Most are 0 KB, several a couple of hundred KB and some many MB's.

Er, they are not much good sitting there clogging things up.

Regards,
John Tellick.

John,

I'm on limited and intermittent access right now, but in case no-one else has commented:

- please keep up to date with the current MSG Data Manager:
http://www.satsignal.eu/software/msg_dm.htm

- please add yourself to the e-mail notifications for updates at the bottom of this page:
http://www.satsignal.eu/software/updates.html

I'm sorry that you missed the announcement, which was on several Yahoo groups. I try not to e-mail users directly, as some would regard it as spam.

Delete the temporary files older than one day. If the RAMdisk is near full, and it's otherwise convenient, I would stop TelliCast, delete all temporary EUMETCast files, delete the *.FSY in the RAMdisk, and restart TelliCast. The temporary files are from incomplete data transfers.

Cheers,
David

David,

Thanks for the advice regarding both problems.
I somehow thought it was a matter of 'you haven't updated your software.'
Some of us never learn?!

I do see the regular notifications of updates from you on the groups but
.....

If the RAMdisk is near
full, and it's otherwise convenient, I would stop TelliCast, delete all
temporary EUMETCast files, delete the *.FSY in the RAMdisk, and restart
TelliCast.

This route sometimes works for me to restore my RAMdisk capacity but often
seems reluctant to 'start up' again.
I find it quicker actually to just close everything down and restart as
this clears the large fsy's and resets the RAMdisk.

Thanks again - off to update and delete unwanted files.

Regards,
John

Thanks Ian for the confirmation - perhaps it is to do with implementing a filter - we hope!!
