I had a look at all three sats Noaa_20 (VIIRS), Suomi_NPP (VIIRS), and FY-3D (MERSI) for the last 3 days.
It's quite obvious that the EARS processing/dissemination chain is broken somehow. I'll report that to OPS.

Thanks Ernst. As I said previously it is suspicious that it is (from memory) the 3 satellites that transmit in the 7800 MHz band.

Douglas.

Sorry David,I did not have any files as I was not taking the satellite data as I had no way of using the data in windows.
I will start taking data tomorrow for one day, so I have files available.

Hi Rob and David

Here is one attached

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

Many thanks, Graham. Do you happen to know anything about file names, and what length (minutes/seconds) each file is? I see GEO1K files which are ground location data, I guess.

Cheers,
David

Re: Eumetcast Tuner

Hello

I would like to by Eumetcast Satellite receiver . CAN be any suitable device
I loose my second processing unit during thunderstorm

Br. Esko Petäjä
------------------------------------------------

Esko,

Sorry to hear that! I don't associate Finland with a high thunderstorm risk.

How did the device fail - was it through the power connections, network connections, or the RF input?

I know that some people have had power supply failures (overheating?). If the failure was through the RF connector perhaps there's a lightning arrester you could fit? These should be easily available for the F connector used in satellite TV, but check they are rated for up to 1.7 GHz (satellite TV could be up to 2 GHz).

Re: Double tuner in T1/T2

David J Taylor GM8ARV 🏴󠁧󠁢󠁳󠁣󠁴󠁿 🇪🇺
 

Hello

I am just updating my systems. Is it possible to use double tuner capability of devices to receive from both transponders T1/T2 with same card. ??

TBS-6903/6908 or SR 1

Br. Esko Petäjä
==============================

Esko,

Yes, I'm using a TBS6903 PCIe card in a PC receiving both T1/HVS-1 and T2/HVS-2 (likely it would do BAS as well but I have no need in that PC). It's in the single-cable configuration. Works well, but the TBS IP reception software continually crashed that Windows-10 PC, so I use BDADataEx instead. It doesn't stretch that PC much - it's receive-only supply a limited subset of HVS-1 data (GOES-16/17 and Himawari) over the house network.

https://www.satsignal.eu/mrtg/performance_lund.php

SR1 - one transponder only.

David GM8ARV

Re: Double tuner in T1/T2

Ernst Lobsiger
 

Hello

Double tuner with T1+T2 reception is possible with 1 TBS-6903 even with a single cable.
TBS-6908 is like 2 x TBS-6903 (overkill, up to 4 transponders like T1 or T2 possible).

An SR1 can only receive 1 transponder of the EUMETCast T1 or T2 kind (with ACM/VCM).
So you need 2 SR1 for T1+T2 and 2 LNB cables or 1 LNB cable and a HF power splitter.

Regards
Ernst

The image should have the Isle of Man close to the pass "center": So about half of the expected pass is missing!

That is exactly as I get Ernst. In fact for months prior to that scenario there was a version with just a band across the UK missing and some files for further north.
This has been an issue for a while.

David,

The official HDF4/5 does not work for FY3D and as Douglas has confirmed
EUMETCastView has not been updated for Windows for FY3D

As neither of these programs work I will assume there is little point in
sending any files.

Many thanks for your offer of help.

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

Ian,

Remember that Windows now has a built-in subsystem for Linux, so perhaps that may be the best route?

https://docs.microsoft.com/en-us/windows/wsl/install-win10

It's relatively easy to install. Then you can have the best of both worlds!

Cheers,
David

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

Ian,

All my work with HDF-5 is from scratch, so I was wandering whether I could at least read the files and produce an image. That's why I asked.

However, even if the official HDF-5 reader can't read the files it suggests they are not in strict HDF-5 format! I thought that was why all the new data was moving to HDF-5 as everyone could read it!

David

Maybe the HDF4/5 official viewer software would work, or EUMETCastView?
I don't take those files, so if you could send me a sample around local noon I can take a look.  No promises, mind!
