Thanks for letting us know, Robert. I do hope that all goes well for you.

Perhaps set up some remote control software such as AnyDesk for any future occasion?

Hi Douglas

That was my plan yes - Im not sure how the files get moved across but I will sort that out at some stage

Re the issue i asked you about with missing data on VIIRS,NOAA20 and FY3D I emailed OPS and got the following reply

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

Graham,

If using USB there's an element of luck judging by my recent experience, and I find a network connection to be more reliable. I have two PCs which are essentially capture-only, both not this year's model!

BAS:
PC Harstad, https://www.satsignal.eu/mrtg/performance_harstad.php
8 GB memory, i5-4460, no special graphics card, 500 GB HD, 4 GB RAMdisk
2nd network interface for an SR1.
If I were buying today, I might get 16 GB RAM, 128 GB SSD (system) 0.5-2 TB HD as data buffer
Received data is on RAMdisk, and a Robocopy job moves it to the HD every minute
Received data offered as a network share, so the MSG Data Manager etc points to \\Harstad\received - used by PC Penguin.

HVS-1 & HVS-2
PC Lund, https://www.satsignal.eu/mrtg/performance_lund.php
16 GB memory, i5-6400, no special graphics card, 128 GB SSD, 4 TB HD as buffer, 10 GB RAMdisk
TBS6903 PCIe card with "single-cable" operation.
For various reasons:
HVS-2 received on RAMdisk and deleted immediately.
HVS-1 received on RAMdisk and Robocopy moved to HD, and unwanted deleted immediately.
Wanted HVS-1 channels (Metop-A, GOES-16/17) made available as network shares for another PC to receive (PC Penguin), shared over the house 1 Gbps LAN.

SVMC_ files are 600+ MB monsters which, in my view, deserve no place on the BAS!

One advantage of the two PC system is that you can, if you wish, disable updates on the RX PC so that data is continually collected, and the processing PCs can be kept up-to-date with Windows Update without data loss.

I hope all the above is correct.

E&OE

Cheers,
David

Re the issue i asked you about with missing data on VIIRS,NOAA20 and FY3D I emailed OPS and got the following reply

Dear Graham Woolf,

 

We do not see any problem with the data and we are also not aware of problems with SNPP VIIRS, NOAA20 or FY3D.

The files you mentioned are this type: 

SVMC_npp_d20201021_t0012197_e0013439_b46544_c20201021002140000768_eum_ops.h5

 

and 

SVMC_j01_d20201021_t1053534_e1055161_b15154_c20201021110350000946_eum_ops.h5

 Could you please send us the tellicast log files (recv_bas.log and recv_hvs-1.log) in order to check all the files  were disseminated via EUMETCast?

 We hope you have the tellicast log files in verbose mode.

Unfortunately I dont run in verbose mode

Regards

Graham

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

Graham is your intention to receive and save the data only on your Eumetcast computer and use the other computer (across a network ?) to process the datas. For future larger data sets I am thinking along those lines as well although I already have a very good specification back up computer (8 years old) I could use.
Initial quick tests seem to indicate that the occassional losses do not stop.

Douglas.


Re: PC Spec

Graham Woolf
 

For example

There is no point buying an i7 if an i3/i5 would do
Also there is no point buying 32GB of RAM when 16 would do
Do I need three HDD's for the three services or would one big one do

Should I use linux or Windows?

Its these sort of question I would like some advice on as it will only be receiving -it wont have any internet connection

Graham

Re: Silicon Labs CP210x driver.

Hi John,
My impression was that you needed to connect the SR1 to the desired com port (no clashes - I also run a weather station that uses the same sw) and then the port would show up in the device manager.

Hello All,

I'm going round in circles!

Does the SR1 have to be disconnected before you install this software?
The Ayecka SR1 DVB Receiver EUMETCast Guide appears to suggest this.

I run 24/7 and don't want to interrupt the service but Ops suggest that my TC missing packets and SR1 Controller anomalies might be due to using the data link for monitoring.
I have bags of SNR and my computer is not 'stressed' so I shouldn't see missed packets(?).

I have cleared out all my old copies of CP210x - which were 'all over the place,' and just downloaded a fresh copy.
I unzipped the zip file and ran the installer and the Wizard told me that the software/driver was ready to use.
However, it refuses to show in Device Manager Ports (COM & LPT) list.

I'm losing the will to live.

Hello, I'm new to Eumetcast service and related software. Is there any way

there also a way to change remapping in 1080x1920 intead of 1920x1080?
Thanks
===============================

Daniele,

Interestingly Craig Anderson used my original ideas for CLUTs, and my CLUTs
work with some of his software.  The basic CLUT is a 100 (wide) by 256
(tall) 24-bit .BMP file, where the horizontal mapping is the selected
thermal channel -60C to +39C, and the vertical mapping is the brightness
channel 0..255.  You can add whatever colour you want for each combination
of temperature and brightness.  There are downloads from the GeoSatSignal
Web page:

  https://www.satsignal.eu/software/geosatsignal.htm

Look for the name: " Ton Lindemann".

Remapping:  the quickest solution would be to use the 2560 x 1920 mapping,
and crop afterwards in your favourite image processing software.  I could
perhaps add 1080 x 1920 as an extra option later.

Cheers,
David

Group subscription poll #poll-notice

David J Taylor GM8ARV 🏴󠁧󠁢󠁳󠁣󠁴󠁿 🇪🇺
 

The subscription for this group will be due at some point. There is the option of downgrading to a free group, but there will be a $220/year charge should we wish to retain features such as a Files section, and a Photos section which we currently enjoy as a Premium group (it was free to start with). There's a full feature list here:

https://groups.io/static/compare

My feeling is that the features of a Premium level are worthwhile, so I wonder whether you agree? We have over 800 members, so if even a small proportion of those chipped in a small amount (say £/€/$ 5) we could keep the Premium level.

What do you prefer?

Thank you for voting. Results will be available when the poll is closed.

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

Thanks, Christoph. I may do that, although the system is already mixed in that It's an Amateur Radio system (see: Pi-Star if interested) and logging there should be in UTC, all my MRTG logging is in UTC (which is clock time for half the year here!), but the included Dashboard software is in local time, which agrees with the wall clock if I want to know who was last on!

The program is supplied as a pre-built RPi image, to which I add things like NTP and MRTG, so any changes I make would be lost and the next major version. Hence I fiddle the lest, to create the least amount of work in the future.

Most probably it's only relevant when you schedule image processing.
If you have a certain time of sat overhead from filenames it's UTC.
Adding some slack for timelyness (preprocessing by EUMETSAT) it's
still UTC. But the Windows scheduler might only work with local time.

Re: Solar outage.

geojohnt@...
 

David,

Yes, sorry about the RTF - I don't know how I manged to get logs of 'both flavours.'

TW, I got a couple of 12 volt 3 amp mains adaptors from CPC today and the new one for the SR1 runs very much cooler than the old 12 v 2 amp adaptor.

Regards,
John.

+++++++++++++++++++++
 
John,

I had wondered whether the power level was too high, but I don't think so 
at -25 dBm.

Yes, that's why I plot these things.  An offset in days of maximum suggests 
an elevation offset, and one in time an azimuth error (skewed, of course to 
the ecliptic (IIRC)).

Thanks for the text log (but no the RTF one).  I can't see any errors there, 
so perhaps this "not locked" is a sensor error rather than a real issue? 
Would be nice to hear from someone else seeing this error.


Cheers,
David

David,

Normal signal level (SNR?) at that time of day is 13.2 - 13.1 dB.

If you mean Power, then -25.0 dBm.

Interestingly(?) my decrease in SNR was slightly worse by a couple of
decimal points on the day after my closest co-linearity.
Both your WXtrack and Sun Outage Visualiser Simulation agreed on the degree
of co-linearity on both days.
Which might lead one to conclude that my dish elevation is slightly out?
But given that my clear sky SNR with a 1 m dish is usually 13.2 dB +/- 0.1
dB, I don't think there is much wrong with the alignment.
Certainly not enough to adjust the dish to try to gain an extra 0.2 dB SNR.

Attached a screen shot the day after my predicted maximum outage showing
SNR, BS and HVS-1 parameter readings.

And the BS and HVS-1 TC logs for the 6 second period of the SNR showing NO
LOCKED.

Have I said this before(?) I'm beginning to think that this NOT LOCKED
indication every now and again by the SR1 Controller is an anomaly related
to my fairly frequent indication of negative Traffic.

Regards,
John.
