Re: TC V2.14.4 and RAMDisk?

David J Taylor GM8ARV 🏴󠁧󠁢󠁳󠁣󠁴󠁿 🇪🇺
 

Hello Group,

I wonder if there are users in the group with a one PC receiving/processing system, receiving all BS and HVS-1 imaging and using a RAMDisk.

As many will know I've at last moved to TC V2.14.4 for BS and for the reception of HVS-1 channels with 'varying degrees of success.'

I'm running:
MDM - MSG-4, IODC, RSS GOES-16, GOES-17, Himawari - and Animator for RSS.
AVHRR Manager, 2 X Metop Manager.

All 24/7.

I have good BS SNR, and 'more than adequate' on HVS-1 from a 1 m dish and Inverto Black Ultra LNB

Now, my single PC system computer - i5-4690K @ 3.5 GHz, 16 GB RAM, 64 bit Windows 10 - appears to have slowed down since having all the extra programmes running in regards of opening and loading data for HRPT Reader and GeoSatSignal.
Not a problem but one now has to wait a little longer.

I noticed since upgrading to the 'latest' TC, that my previous RAMDisk of 997 MB is not being used.
OK, I know that TC V2.14. xxx is designed to do the job of RAMDisk in temp folders, and I see it does just that.

However, I had a look at the 'latest' EUM TD 15 yesterday and see that it has quite a lot of information on configuration and using a RAMDisk.
Not only that, suggesting(?) the use of SSD's against HDD's, for their speed.
Pages 34 - 35.

I know that SSD's are not in favour by some(?) but I wonder if anyone has any comments/experience on 'still' using a RAMDisk and using SSD's in the data path?

Regards,
John Tellick.
=================================

John,

Others have used SSDs successfully, although I haven't here. You may like to check the life expectancy given your expected data flow - I recall one system reported here had three SSDs, one for each service.

My own systems are:

PC Alta: receive and process a selected set of the BAS data. 1000 MB RAMdisk. No HVS processing or reception. 240 GB SSD system disk, two HDs.
https://www.satsignal.eu/mrtg/alta-ramdisk.html

PC Stamsund: receive and process selected BAS with 1300 MB RAMdisk. Process HVS-1 data received over the network from PC Lund. Receive but not process HVS-2 data, it's deleted soon after reception. Two HDs.
https://www.satsignal.eu/mrtg/stamsund-ramdisk.html

PC Kiruna: process selected BAS data received over the network from PC Harstad. Receive all HVS-1 data direct to separate HD (no RAMdisk) with selected image data processed. 256 GB SSD, three HDs. No RAMdisk

PC Harstad: receive-only selected BAS data, temp & received on 4000 MB RAMdisk, moved to HD with Robocopy. Data fed to PC Kiruna. Single 1 TB HD.
https://www.satsignal.eu/mrtg/harstad-ramdisk.html

PC Lund: receive all HVS-1 and HVS-2 data. HVS-1 data temp and received on 10 GB RAMdisk, moved as soon as possible to 4 TB HD using Robocopy, where it is served over the network to PC Stamsund. HVS-2 data temp & received on the same 10 GB RAMdisk, but deleted soon after reception.

https://www.satsignal.eu/mrtg/lund-ramdisk-trees.html

They "just grew" like this! There's quite a lot of data I don't use, but I want to keep receiving all the HVS-1 and HVS-2 data so that I can compare with Arne. We both submit automated daily reports to EUMETSAT. I have TrimTree jobs doing this, which also remove unneeded processed data (e.g. much of the sounder data). It just grew like this.

All of the systems are capable of loss-free reception when conditions are right. Instantaneous signal drop-outs are better handled by the TBS systems, possibly due to a faster AGC response (I've been unable to confirm this), the system most susceptible to missed data due to disk activity is Stamsund, without a separate system disk. All systems running latest Windows-10 (1903) and latest TelliCast.

Arne's system does what you want (all three services), with an 8 GB RAMdisk, but he uses a much more complicated script. My Robocopy/TrimTree method does the same job, as far as I understand.

Your turn, you choose!

Cheers,
David

Re: Dartcom Receiver

Graham Errington
 

Thanks Rob,

I was surprised to find that information is limited on the Dartcom receiver when looking on the internet and I wanted to keep sure I knew what to do with it and was I doing the right thing in buying it.
I have the unit on loan so I can have a play around with it in order to make up my mind, I'm hoping that I will have a turnstile antenna up later this week and at the very least sea if it is receiving the weather satellites okay. 
My other concern was would it have a limited lifespan in relation to the satellites available.

Re: Dartcom Receiver

Hi Graham,

I would have replied sooner but my email was not working. I just reverted back to win 7 from win 10 on all three of my pc's, can't be doing with all the latest systems. I might add that the Dartcom system you were  posting is a system 1 recvr and does not receive all the latest sat frequencies. I have a sat II rcvr but just recently upgraded to the APT-06 as I have the same problem with frequencies and my R2FU got damaged in the house move. If You have any questions I would be happy to help.

Hi to all,
sorry for troubble but I have not found any usefull help,too many topics with the same title , more or less, but I havent found a solution.
This in my situation :
With old tellicast a eku (TC 2.4.4 and old Eku) I read all my subscribed channel, and , under LICENSE, I read , in 4th position, ****.**** etc string.
Now I' have update the eku and tellicast to last downloaded fron eumetsat ftp site.
Start Uku and basic service, click on TEST.EKU.bat and I read , in 4th postion,host key, of the popout window, the ****.*** string.
Open tellicast shell,in log I read may message ,and afther 5/6 sec , I read  'could not join channel  etc etc...'
Under License , my 4th position is empty.
If run HVs-1 service, under license, my 4th position is regular "***.*** etc"
Is there any one with a solution?
thank's in advance to any

From about 16.55 Uk time some MetopA polar wind data (amv)
is incorrectly being sent on channel EPS-10 Basic service. MetopA polar
wind data is as it should be coming through EPS-10 on HVS-1, so I am not
sure if it is duplication, though a quick check suggests it is not.

Thanks for spotting that, Ian. I suggest reporting to Ops if the issue continues.

I have opened the receiver up and it's not exactly the same but quite a few of the components used are the same.

Would you be able to scan what you have and send it to me, it might help.
