Hello,
I still do not get E1H-TPG-1 and E1H-TPG-2 data.
Under General Parameters , name E1H-TPG-1 I have          E1H-TPG-2 has
state ---connecting in red                                                         connecting in red 
address ---- 224.223.223.3:7013                                             224.223.223.3:7015
priority --     500                                                                        500
bandwidth -9000000                                                                 8000000
received bytes - 0                                                                     0
packet NAKs -   allowed but disabled                                       allowed but disabled
Are the values shown here correct ?
What to do about packet NAKs allowed but disabled ??
May I stress that despite very cloudy skies I have a SNR of 11.4-11.5 and I do receive Goes 17 TPG-3 data !
I look forward to your advice.
Regards,
Roland

Roland,

have you set the PID's 600 and 601 (needed for HVS-1) within your SR1 receiver?
As I don't use the SR1 I have no knowledge how to do this.
Maybe somone else can help?

Cheers,
Thorsten

Thank you for your continued interest, Thorsten !

I do receive part of the HVS-1 data stream. I get only the Goes-17 TPG-3 stream. No Himawari, no Goes 16, etc.

The best SNR I currently obtain - heavy solid clouds - is around 12 dB.

People say that with a - my - 1.25m dish this figure should at least be around 13dB.

I still ignore why I cant get beyond 12dB. I already have spent much time tinkering - readjusting

my dish to no avail. So be it !

I am going to replace my 1.25m dish by a smaller 1m Gibertini dish in the hope to be able

to better finetune the latter. We will see !

I very much regret the decision to switch from 9A to 10A and at the same time to "swamp" 

Eumetcast with a mountain of partly dubious data. Visibly reduced power plus

an ever growing amount of data really is a very very bad combination for the average

Eumetsat Eumetcast user !

Just my personal opinion, mind you !

Regards,

Roland

Roland,

 

You should be aware that EUMETCast is a professional service meant to distribute data in near real time to Meteorological Institutes, weather services and other professionals. The fact that other interested parties and amateurs are allowed free-of-charge access to this data should be considered a bonus. Nevertheless, if you want to share in the data made available, make sure that you only select the data of your interest. You have almost full control over what you want to receive and what not.

It is not really appropriate to talk about ‘swamping’ and ‘dubious data’. If you have no use for it, don’t take it.

 

Besides, quite some people of the MSG- group have been trying to help you and answer your questions. I can’t help noticing that little is done with the suggestions offered and the stream of similar questions/remarks keeps coming back. Food for thought?

Regards,

Ferdinand

Roland,

Do you have this document which explains the setting up of the SR 1?

Regards,
John.

Thanks for your intervention !

Repeating my precise questions apparently is useless as these are not answered.

(e.g. why do I get E1H-TPG-3 but not E1H-TPG-1 & TPG-, meaning of red warning-reset, etc.)

I will no longer nerve the forum with my problems.

Roland

Roland,

 

The message was not to discourage you; instead to encourage reading the pointers suggested to you before firing again.

 

Suggestions:

  • Read PDF_TD15_EUMETCAST.pdf, which is a good how-to guide
  • Read PDF_DVB_SR1_GUIDE.pdf for details on the SR-1
  • Do a search in David’s web pages to the topic you need more info on

 

Specifically: if you are receiving Goes West without problem (Goes-17) then basically your reception configuration should be OK. Most likely you must in that case review your cast-client-channels_hvs-1.ini file. Is the syntax  correct? Is it not commented out?

Do the entries look like below?

 

#            GOES-16 GLM Level 2; PID 601

[channel]

name=E1H-TPG-1

target_directory=J:\EUMETCast\received\hvs-1\E1H-TPG-1

tmp_directory=J:\EUMETCast\tmp-hvs-1

 

#            Himawari-8 10-minute; PID 601

[channel]

name=E1H-TPG-2

target_directory=J:\ EUMETCast\received\hvs-1\E1H-TPG-2

tmp_directory=J:\EUMETCast\tmp-hvs-1

 

#            GOES-17 netcdf; PID 601

[channel]

name=E1H-TPG-3

target_directory=J:\EUMETCast\received\hvs-1\E1H-TPG-3

tmp_directory=J:\EUMETCast\tmp-hvs-1

 

As far as your reception is concerned: unless you currently have a distorted dish, replacing it with a smaller one will obviously not increase your SNR. Let a professional look at the alignment if you don’t manage to improve signal yourself. Make sure that the dish is fully illuminated. I understand you are using the balcony. Offset dishes are illuminated from higher up than center focus and thus the roof of your balcony may block part of the incoming signal.

 

Good luck/

Ferdinand
