Sorry, our posts crossed. Here is a link from NewTec that shows their (5%) Clean Channel Technology

https://www.youtube.com/watch?v=VAcO2YezfZg

AFAIK this was used from DVB-S2 day one in EUMETCast Uplinks and professional NewTec receivers.
DVB-S2X will allow for sharper bandwidth filtering than current DVB-S2 (problem as always is drivers!).

==============================

Ernst,

No problem - it's better to have two explanations than one, especially when they explain things from a different point of view.

Thanks for the NewTec link. With filtering being digital these days, and with chip power ever increasing (more ops per second) I imagine getting sharper filtering may not be too difficult. More power from the satellite is something that many enthusiasts would welcome, though!

Cheers,
David

RollOff means how steep the bandwidth filter prevents from interference by close transponders.
20% is somewhat better (sharper) than 25% but you will probably not see any difference such
as increased power and less lost packets. Originally EUMETSAT was talking about 5% RollOff but
only (Non Standard HW, AFAIK 20% is best for DVB-S2) NewTec receivers can possibly do that.

Ernst

Hello All,

I've been looking at my SR1's status via Telnet and see that the/my Roll Off, # F is set to 25%.

Having been reading the EUMETSAT guide to setting up an SR1 for something else, I see that
their Roll off is set to 20%

So, does this matter?
Does it make any difference?

BTW, I've no idea what Roll Off is.

Regards,
John Tellick.
=======================================

John,

I think it's the sharpness of the filtering. I suspect that (a) the receiver should be the same as or slightly greater than the transmitter (to ensure that all the transmitted bandwidth is received) and that (b) there will be very little difference in practice between 20% and 25%.

I recall asking EUMETSAT the same question many years back and getting a similar response.

Of course, if anyone has better information, do please inform us.

Cheers,
David

If "a few months" is about a year, this change might be of interest:

Hello everyone sorry for the inconvenience.
I reactivated the MSG system after a few months of stand by and I noticed the lack of METOP-C data in the EPS10 folder.
I searched the forum but found no post that could give me any suggestions, I missed some particular changes in the distribution of eumetsat?

Thank's in advance to any!!
Have a nice day!
IZ1KBP, Mario
========================================

Mario,

As you are getting Metop-B you /should/ be getting Metop-C as well. I do wonder whether you need to register separately for Metop-C, but that seems unlikely.

Maybe you are just in a data gap - my last log line reads:

2020-06-30 13:42:40.000 (UTC) created 2020-06-30_1313_M03_08545.hpt

so that's some 45 minutes ago. Metop-C shows as "OK" here:

Mario

Channel "EPS-10"   Metop-B and Metop C  (Basic Service)
Channel "E1H-EPS-10" Metop-A (HVS-1)

That's how the files ar pooring in here.

P.S. EPS-10 versus EPS10 ?

Re: Signal

geojohnt@...
 

Ian,

Yes, I saw from the European users graphs that the SNR did drop back later.

I went out an nudged my dish but couldn't improve my SNR - I see now that this was after the SNR had dropped back.
But I have to say that I wasn't aware on an increase during the '4 hour period.'

The graphs on David's website show that several users saw quite a distinct sustained increase in SNR over that period while others - apparently - saw none, or a minute increase.

I don't understand that.

Regards,
John.

Spoke too soon John and see the signal is back down again after just
over 4 hours. In my case in poor weather 13.1 to 12.5 SNR. At the same
time as the drop in the signal I saw a missed/recovered packet of 5/5
which is quite rare for me, suggesting a station change.

At the risk of repeating myself, it is very annoying that their back up
station has a considerably better signal.

Re: NOAA 19 GAC

I wonder what the issue is with NOAA 19 GAC which appeared to stop mid
morning yesterday 23/06/2020.

NOAA 19 EARS AVHRR is being received so probably not a satellite issue.

Regards
Ian.
======================================

Confirmed that I'm seeing the same here, Ian.

It's showing on the OSSI at EUMETSAT. I haven't received any notices from NOAA, but their e-mail delivery isn't 100% reliable.

Perhaps you might report that to Ops?

David,

Thanks for the gentle reprimand.

In the past I do note any responses to any (unlikely) problems with your beta updates, and then wait for the official update.
But point taken.

As a BTW on the MSG-1 group, does FY-2G and FY-2H only do 1 hourly whole globe imaging?
I couldn't find the answer on the EUMETSAT website.

Regards,
John.
===============================

Yes, as far as I know. Check in the product navigator.

John, using betas is something you may want to reconsider.

As I move further into retirement, the prospect of doing an "official" 
update with all that may entail (e.g. updating the Help which no-one reads 
anyway) becomes less appealing.  As I'm using the beta as my "production" 
environment, I usually feel a high degree of confidence in what I upload as 
a beta version.  You may wish to monitor the Web page:
