Giftmacher,

if you havn't found BDADataEx yet, look here:

More or less everybody under Windows uses CrazyCat's BdaDataEx. I'm under GNU/Linux. No idea where you get the latest version. Search this list.

Ernst

Hi all, is there any better IP tool than TBS IP? Both versions I tried crashes to desktop after few hours of use.

Dear All

I am pleased to report 30 days performance figures of my GNU/Linux receiver Kallisto. It's a Fujitsu Celsius Xeon with a TBS-6909X receiving all 3 services using a RAM disk.
We had a rather dry November and Kallisto has not lost a single packet. I cannot remember to have had such figures ever since we changed from DVB-S to DVB-S2 in 2014.

Cheers,
Ernst


P.S. Please compare:

It's not enough to use only BAS by starting just a BAS client. You have to set a MODCOD filter to prevent HVS-1 from even reaching your PC.
Missing keys are often due to an EKU problem. Put the receiver and EKU in USB2 sockets. Maybe try different USB2 sockets (rear and front).

The LNB contains a down-converter from the 11 GHz signal to a 1.5 GHz (approx) signal, so cable intended for "satellite TV" will be fine.

Maybe a somewhat more advanced Python code like

try:
   layers, height, width = new_scn[composite].shape
except:
   height, width = new_scn[composite].shape

would cover both multi channel composites and single channel "composites".
That's something to be tested for the HOWTO 2.0 somewhere in the future ...

I wouldn't have got the str bit either but I think I have a working script

Douglas

Thanks - it would be great to see your script too

If you use one of my latest scripts with automatic annotation and logos on the left side of the image you might run into an additional problem with 1 channel only. There is a script line "layers, height, width = new_scn[composite].shape" (credits Christian Peters) where I only use the "height" to automagically scale the annotation and logos. In case of a single channel there is no "layers" and this must read "height, width = new_scn[composite].shape". But Python will tell you anyway ...

Good luck
Ernst

Hi Ernst
I need a bit of help please if you wouldnt mind
I have looked through all the reader and composite files and the satpy documentation but I cant find out what I want to do
I want to process just a single METOP channel whether it be visual or infra-red in its raw format so no composites
I have tried this     composite = '4' to process channel 4 data but it doesnt seem to work
What do I need to do do to get a single channel
Regards
Graham

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

Graham I have a script that gives me this image.
I will post it direct later when I get time but you will have to adjust for your own directories/files etc.

Metop uses the 'avhrr_l1b_eps' reader. Under ..satpy/etc/readers/avhrr_l1b_eps.yaml
you see the datasets (channels) you can expect. You can either try by name or
by center wavelength. composite = '4' or composite = 10.8 should work. The later
will fail when assembling the final image file name (because it's not of type
string). In this case change the file naming to ...+str(composite)+ .... Here are
two examples from Metop-B. It's from yesterday, There is no UK data from today yet.

Best regards
Ernst

Ok, since I have no other coaxial cable, I have tried the RAMdisk according to this article

Your first step should be to disable the HVS-1, and get the BAS working properly first. Any errors in the HVS can affect the BAS.

The RAMdisk we now tend to use in a different way.

Weak signal or other errors. Could be a wobbly dish.

Maybe the repeater USB cable isn't best idea. Most of the pictures are incomplete.

I think it more likely to be one of the PC issues I mentioned, but try a longer RF lead as a test. The RF gain is in the LNB, so longer cables can be tolerated.
