Ernst,

 

While creating a script for stacked night-dnb for Noaa-20 or Suomi (see sample working version attached), I do not manage to include the night passes from before midnight.

I would not know how to modify your formulation:

files = glob(segdir + '/' + 'SVDNBC_j01_d' + Yea + Mon + Day + '*_eum_ops.h5')

to include the DNBC files from the evening before, as ‘Day’ is already defined in the file name and the previous day includes not only the evening DN passes, but also the morning ones.

Do you have a suggestion?

 

Cheers,

Ferdinand

The splitters not arrived yet but this is the one https://www.amazon.co.uk/gp/product/B077DW5GVT/ref=ppx_yo_dt_b_asin_title_o05_s00?ie=UTF8&psc=1and it looks like that  no DC block integrated. So  I will fit the DC block right on to the TBS card and then fit the coaxial cable in to the rear of the DC block , then this  cable then goes to the splitter. If i move the HVS-1 to the TRBS card i will need to use both tuner O and tuner 1 in the settings.....although i havent used the BDADataEx software until i can set up the installation of the cables.
Many thanks
regards
Philip

Philip,

first make sure your splitter does not have a DC block integrated. If yes connect the SR1 on the side where DC can flow through to the LNB. As you have a running system
the SR1 will further power the LNB and set the right band and polarisation. On the DC blocked side you can experiment with the TBS card. If you are sure the splitter does
not block DC on either side then fit a DC block right onto the TBS card. In the long run the best system you can setup is taking HVS-1 and HVS-2 with the TBS in its "single
cable mode" and BASIC Service *only* with the SR1 setting the appropriate MODCOD filter. How to do this you find in the SR1 Manual and on David's page as usual ...

Hi again
I have now purchased all the bits for my set up to receive HVS-2.
The attached file shows a diagram of where i think the cables will go to the Ayecka SR1 and TBS6903.     But the F-TypeC DCBlock , i am not sure where this is fitted. Can anyone help please before i connect everything up.
thx
regards
Philip
After that i will use BDADataEx  to configure tuner0 on TBS-6903 and cross fingers it all goes to plan.

David,

That was an interesting link.
I hadn't thought about using silicone grease.
I ordered some F connector boots last autumn and they were 'too small.'
I had to cut a 'split' in them to fit over the F connector - thus exposing the cable entry on one side of the boot.
Not good.

I usually use self amalgamating tape which works well till you need to undo/get to, the connector/cable.
Can alter your dish alignment as you fumble around..

If Philip meant 'what cable should I use.' then CT100 is the 'satellite TV standard cable.'
There is also RG6 - but I don't know anything about this.

CT100 comes in 'silver' aluminium(?) braid and foil or copper braid and foil versions.
I have used both and think copper braided and foil cable is 'better/preferable.'

Regards, 
John.
 
+++++++++++++++++++++++++++++



Generally "F-connector", but I have seen cable size variants so if I was 

being very fussy I would order the connectors from the cable supplier.

Some hints here: http://www.satcure.co.uk/tech/fplugs.htm

Hi All

Have finally got Windows 10 re-installed along with python perl etc etc

Have got BDADataEx running too with my TBS5927 so am now waiting for my 6909X to arrive tomorrow but I dont anticipate too many problems

I also have all my Version 1.0 python scripts running again so will have a look at V3 later in the week

Douglas,
of course you can just use what you have from V1.0. But V3.0 is a leap step forward. You get fine control of overlays like coast lines, borders, rivers, POIs like cities or your station.
You also get additional Satellites like Sentinel-3A/B and can choose from a plenthora of composites. And last but not least the quality of my Python code has been much improved.
To give V3 a GO you do not have to start from scratch. It should be possible just to upgrade the Miniconda3 and Pytroll/Satpy environment you have. You can do this as follows:
Open a Minicoonda3 CMD Window and at the prompt "(base) C:\Users\yourname>" just enter "conda update conda" to get the latest version of conda
Then change into the Pytroll environment with "conda activate pytroll"
The prompt should look now "(pytroll) C:\Users\yourname>"  and a "conda list satpy" will show you the Satpy version number you are working with (write that down for Murphy)
The latest Satpy version is 0.25 today. You update at the above prompt "(pytroll) C:\Users\yourname>" with "conda update satpy" (this may take a while) and you are done!
Then you can give V3.0 scripts a try with your updated version of Miniconda3 and Satpy like either a) or b):
a) Either by renaming your current EMCtools and EMCdata to EMCtoolsV1 and EMCdataV1 and just installing V3 as EMCtools and EMCdata and *copy* the whole coastline stuff from V1 to V3
If you do this the scripts in EMCtoolsV1 will not work anymore due to the renaming of the top directory but everything should work in your new EMCtools and EMCdata (which are now both V3).
You just have to adapt segdir in the V3 scripts. You can keep your V1 stuff as archive for what you have done as long as needed.
b) Or you can let everything as is and install V3 in subdirectories like "C:\V30\EMCtools" and "D:\V30\EMCdata" then *copy* the whole coastline stuff from V1 to V3
You can now work with both versions using the same updated Miniconda3. The only minor problem V3 will still use the pppconfig from V1 as the environment variable is pointing there.
This means that a couple of newly defined areas like 'hawaii', 'japan', etc. are missing. If you never changed your V1 .../pppconfig/areas.yaml you can replace it with V3 .../pppconfig/areas.yaml
You will have to adapt segdir and  toodrp = 'C:\V30' and datdrp = 'D:\V30' in the V3 scripts.
If you want to ditch V3 then
a) delete the (V3)  "C:\EMCtools" and (V3) "D:\EMCdata" and rename the V1 versions back.
b) delete the  "C:\V30 and the "D:\V30     (...that contain (V3) EMCtools and (V3) EMCdata).
Hope this helps
Ernst
P.S. Also be aware that we have now experienced users on V3 like Ferdinand and Hartmut (I suppose Graham will follow soon) that can help you in case of Windows problems.
===================================================================================

Many thanks Ernst. Ferdinand was also good enough to advise me as to what was updated and the nature of the changes. So yes I will do the update and do it properly.
I did not update Miniconda/Pytroll up to now so I will do that by removing the old versions via Control Panel/Programs for a clean install. One thing we have plenty of at the moment is time in the house. The only thing I hope to go out for soon is my vaccination. !

Thanks again Ernst for both the work you have put into this but also your encouragement to the black tea shirt group <smile>.

Best regards,
Douglas.

Ian,

I assumed that you use "ian" as Windows user name. If you open the black CMD window you should see C:\Users\YouWindowsUserName.
Still assuming your username is "ian" then in the black Window you can try > cd Desktop, Enter, and you are in your Folder Desktop. C:\Users\ian\Desktop> dir then Enter should list the files on your Desktop (unless you have deleted your Desktop as well ...). To install Miniconda3 you can also put the downloaded Installer.exe on the Desktop and do as described from there.

You can forget about the "hash" comparison. This is only extra, super security. You probably have a virus scanner anyway.

Regards,
Ernst

I have now completed all your scripts with my own settings, and did not run into any inconvenience. The multiscene addition works very smoothly and the same is true for the night light options for Noaa-20 and Suomi.
There is plenty of room for further tuning to one’s personal interest and automation is easy. In short: an excellent howto for many Eumetcast users who feel reluctant to take the jump. Thanks again for the fresh impulse into the satellite world for both hobbyist and advanced user.
All,
Don’t hesitate and follow the HowTo that Ernst has made available. It is seriously easy to follow and implement, just as is the case with David’s suite of programs, and it brings direct result to your screen. Apart from widening the possibilities to work with the current data, a great advantage is that it opens up a road into the future. The people behind Pytroll/Satpy are continuously expanding the scope of work and improving on what already exists. It is for most people the only way to smoothly transition to MTG and Sentinel 5 onwards without having to spend big money.
So, take a first dip into this fresh water!
Good luck.

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

I echo your words Ferdinand.
However just one question if I may.
Since succeeding with V1, apart from changing/developing scripts etc., I have not updated anything.
Presumably I now need to start again with a new update of Miniconda and Pytroll. That seems to me to be a complete start from scratch. I question the benefits when the arrangement I have at the moment seems to handle all my needs admirably. I am just not sure what the benefits are and if they outweigh all the additional work.

Best regards,
Douglas.

Dear Members



Here comes the Pytroll/Satpy EUMETCast Windows Starter Kit V3.0 (YES 3.0). It should be "Childs Play" to get it working.
I have double checked all the scripts on my Windows 10 Pro 64Bit PC that got the files readonly from a SAMBA share Z:.

My definition of "Childs Play" remains the same as for V1.0:

 0) You know that you have Windows 10 64Bit
 1) You are not completely new to EUMETCast
 2) You read and follow the HOWTO inside (RTFM)
 3) You know where you find your satellite files

All scripts have been developt under Debian 10 GNU/Linux. An almost identical Starter Kit for this OS will follow soon.

Have fun
Ernst

Ferdinand,

thanks for the nice words. I hope indeed that the Club will grow to a size where Windows members can help each other. Don't forgent that we can be part
of an ongoing development of something huge. We will from time to time run into minor problems or bugs and must accept that these are often not the topmost
priorities of the main developers. As an example of such a SatPy bug the coast and grid lines west of London are sometimes missing in 'omerc_bb' areas.

Another problem may arise if your files are not the compressed way I use them due to my 2 PC setup. But Hartmut has already shown that with a minimum
Python such problems can be resolved quite quickly. The possibilities how the user can configure the outcome of *his* pictures are certainly unprecedented.

Have fun,
Ernst
