XRIT2PIC.

Douglas Deans
 

As a matter of interest is anyone successfully using XRIT2PIC with Windows 10.
I decided to give the program a try again and despite days of effort, all previews, images etc are empty ie black window.
There is no indication that anything is wrong.
The data I am using works with David's programs, Pytroll/SatPy and EumetcastView so is sound raw data.
Clearly I am missing something.

Any comments would be appreciated.

Regards,
Douglas.


Re: EUTMETCast DVB-S2 Unable to lock

Hello Ernst,

Thanks for your comments.

Yes you are right, I'm sure this is the way professional satellite receivers are configured and makes sense for C-band and Ku-band reception configuration.

And I see the professional Novra receiver configures this way also.

Since the birth of EUMETCast via commercial Ku-band satellites, we have (mostly) used the Skystar 2 card and the DVBWorld receiver, both domestic (and cheap) satellite TV receivers so one - I - have become used to this.
Tuning/configuring, these via the 'IF frequency' would not have been a good idea for the 'general public' and myself.
As is the case today with domestic satellite TV receivers.

I see that TBS cards use the 'satellite frequency' in setting up also.

A question of 'old dog - new tricks?'

>(I checked the other transponders on LyngSat and FlySat of all satellites near Eutelsat 10A. It must be >Hotbird 13°E).

Yes, I too have looked at adjacent satellite frequencies.

Berst wishes,
John.

The SR1 approach might be more universal. Think of L-Band LNBs for EUMETCast Africa with different LO Frequencies.
But of course you basically have to know how an Universal LNB works, what 13 / 18 Volt and 0 / 22 KHz signal changes.

Here is a GNU/Linux tuning file I copied from an archived version of a site I had pre 2014:

Yes, it directly uses the transponder frequencies. Not sure the rest looks more comprehensive to you though :-).

The first line shows that the profile Quentin can lock is meant for the old pre 2014 EUMETCast DVB-S on Eurobird 9°.
It seems this is still around on EUMETSAT's ftp site. Now in 2020 it accidentally fits to "Sky Italia" TV on Hotbird 13°E
(I checked the other transponders on LyngSat and FlySat of all satellites near Eutelsat 10A. It must be Hotbird 13°E).

Re: TBS 5927

David J Taylor GM8ARV 🏴󠁧󠁢󠁳󠁣󠁴󠁿 🇪🇺
 

I have been following some recent mails re the above in particular those
from David.
My own observations re the TBS 5927 over the last 1/2 years is that the
TBS 5925 produces slightly better results ( usually 0 missed and 0
missed/recovered ) which is disappointing given that the TBS 5927 is the
latest USB receiver with the updated hardware.

In the last 48 hours I updated the driver for the TBS 5927 to 1.0.0.7
and unfortunately it appears its performance has deteriorated a little
more, although I intend to test it for a longer period.

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

Ian,

Yes, the older PC I'm replacing had a TBS5925 which could produce 0/0 results, but the age of the PC (required spectre/meltdown patches) and the consequent slow file system produced other losses. I still have the TBS5925, though.

Changing the driver, and relocating the TBS5927 from a USB 3 to a USB 3 port hasn't made a significant difference. As you say, this sort of test requires measurements over days, rather than minutes or hours, unless something is obviously wrong.

Thanks for the report.

Re: EUTMETCast DVB-S2 Unable to lock

geojohnt@...
 

Quentin and Ernst,

Quentin, it seems you do not have David T's WXsat programme which would give you the solar crossing time for your location?
No matter, dish pointer is very useful as you can click and drag the dish pointer to the exact location of your dish and get its accurate location parameters and the satellite's parameters from your location.

Oh, and beware, this programme shows LNB skew looking from behind the dish - not 'from the place where you would be standing to adjust the skew!'

You could then use  https://www.timeanddate.com/astronomy/ with these parameters (and/or Ernst's suggestion) to see the time when the sun crosses your dish.
As Ernst says, you need to be quick and accurate.

Ernst, one thing I find 'annoying' is that the SR1 uses the downconverted (LNB) frequency in setting up not the (as with satellite TV receivers) the 'satellite's transmitted frequency.

I wonder if this is also so with the TBS (and other) receivers?

It's just seems to be another complication (for me) to be overcome.

Regards,
John.

If you want to try the solar trick and do not have software to determine the exact solar position with time you can do this:

1) Go to dishpointer to get the azimuth (NOT the magnetic one).
2) Go to the NOAA solar position calculator. You will have to enter the time a couple of times to approximate your azimuth as close as possible
(there used to be a site of a french guy that did it all automagically and gave the time for azimuth. Does anybody have the URL? Is it still online?)

https://www.esrl.noaa.gov/gmd/grad/solcalc/

3) Set your clock exactly, go to the dish, put the tape on, and wait for the sun ...

Another alternative for overcast skies is to use online dish pointing calculators such as:-

https://www.dishpointer.com/

or

https://www.satsig.net/maps/satellite-tv-dish-pointing-uk-ireland.htm (UK and Ireland only).


A quick Google search will find others.


The advantage of these websites is that they draw the line on a Google Earth map for you so you can see which local features you need to point the dish at, to accurately set it in azimuth.

You don't need to know the azimuth only the satellite that you want to receive.

Using the sun is a good practice. But it includes a couple of things (including having *EXACT* maybe even UTC time).

1) You must know exactly azimuth and elevation of EUTELSAT 10E as seen from your location. (use the dishpointer site).
2) Find out the time the sun crosses this azimuth the day you make your pointing (for elevation use the mechanical scale).
3) As John said: Span a black plastic tape from the top of your dish to thr LNB (a string might not give enough shadow).
4) At the very time the sun crosses your azimuth the shadow of the tape must be exactly in the center line of the dish.
You will not have too much time as the sun is moving fast: 15° per hour makes 4 minutes for 1°, you will have 1 minute!

There is an alterative for overcast sky:

1) If you know exactly the azimuth go to Google Earth at your antenna location (go close, the screen should show about 5km south).
2) Draw a line with this azimuth from your antenna position in the direction of the satellite (you can do that with your browser).
3) This line will cross buildings or other points on the ground that you can identify from the antenna position (1-2km distance)
4) Make a screen copy and/or printout that you can take with you for identification of the points as viewed from the antenna.
5) Put some exact construction of a 90° angle across your dish and aim with your bare eye at the side to the identified point

Above link shows you are watching TV on "Sky Italia" 11977 MHz

You are on Hotbird 13°E, even with a 90cm dish you cannot lock transponders on Eutelsat 10E. Just my 2 cents.

Re: EUTMETCast DVB-S2 Unable to lock

Quentin,

I think you may be pointing at the wrong satellite.

I've just found this on EUMETSAT's website:


D17) How to identify the satellite or transponder on DVB-S2 Ku band
SYMPTOMS
DVB-S2 parameters are correct, there is signal, but no lock and no data.
PROBLEM
Antenna may be pointed to the incorrect satellite and the another transponder is received.
How can I identify the correct transponder is selected?
The following transponders in the vicinity of E10A are locked with a green LED by the SR1 DVB-S2 receiver or may be indicated with a high signal level by other receivers:
16°E   11262 MHz   27.5 MSymbol/s   QPSK 2/3
13°E   11258 MHz   27.5 MSymbol/s   8PSK 3/4
10°E   11262 MHz   33.0 MSymbol/s   8PSK 3/5, 16APSK 2/3 (EUMETCast)
07°E   11262 MHz   30.0 MSymbol/s   8PSK 3/4
Any these transponders can be received at the EUMETCast downlink frequency of 11262.5 MHz, depending on the antenna pointing.
SOLUTION
If the 16 °E or 13 °E position is identified, point the antenna slightly more West.
If the 07 °E position is identified, point the antenna slightly more East.
Move the antenna in very small steps and observe the reception status until the 10 °E position is reached.
++++++++++
I hope the above might be useful.
One trick that Arne van Belle uses and I find is a help, is solar crossing of the dish.
Twice a year of course the sun 'crosses' directly behind the satellite and causes interference for several days - 'solar outage.'
The sun also 'crosses' the dish every day and what Arne suggests is attaching a piece of string from the 'centre' top of the LNB to the top rim of the dish again centrally - if you see what I mean.
Then you find out the time of the solar crossing of the dish for 10 A from your location.
You can do this from David T's WXtrack > View > Solar Outage > Solar Crossing. 
At the solar crossing time at your location for 10 A the shadow of the string should be right down the centre of your dish.

So that might be a useful task?

Re: EUTMETCast DVB-S2 Unable to lock

Quentin P.A. Leroy
 

David,

Indeed, this is what leads me to believe I'm not receiving either transponder C4 or C10, nor basic service nor HVS.

Whenever I try the 1513.000MHz frequency with DVB-S2 standard, ACM or VCM mode, leaving the rest auto, the signal doesn't lock at all.

That's why I tried the 1376.000 MHz, that I found in a configuration file from a eumetsat repository: ftp://ftp.eumetsat.int/pub/OPS/out/user/EUMETCast_Support/EUMETCast_Licence_cd/Windows/DVB_devices/SR1/SR1_Configuration_Files/
This config file was rather minimal in explanations, it only mentioned "EUMETCast DVB-S" for this setting.
It is the way I interpreted your first advice, this look to me like another "channel" I manage lock on, which could be a good first step to understand if the antenna is correctly aligned.

I think that if I could found out what am I listening to at this frequency, it would be a helpful information.

xrit2pic hdf5, also for Pi

R. Alblas
 

xrit2pic now also supports HDF5 for GOES16 and MTG (not launched yet... ).
Available for Linux, Windows and Raspberry Pi, all 32-bits. (Should also run on 64-bits systems.)
For Pi it even runs on a very old (2011) version.

See:
