Re: dvbreport

David,
after getting the data streaming again, I modified my mrtg.cfg file to
contribute the new results. Unfortunately, dvbreport seems to shoot off the
IP data stream. I first just had it included in mrtg.cfg. Some minutes after I
had started that, the pink T turned crimson. Before that, according to the bit
counter of the dexatek IP-screen, 16 Gbits had passed without an error. I
am not sure how reliable that parameter is.

OK, I started the data flow again (had do it in the Dexatek IP-configuration
screen (btw, today, with the presently used older version, it had found all
PIDs automatically)), and after some minutes, the T became crimson again.
I switched off the perl script - leading to a cw operation of the receiver.

Then I started dvbreport once manually from the dos box. It produced four
correct result lines (72 81 0 0), and two seconds later: crimson T.

My Dexatek.exe is Verison 1.0.0.1, it says. And I have set the IP to
192.168.238.236, since Windows complained that both ~237 and ~239 were
still in use from my previous attempts and asserted to a microsoft a/v
interface.

Of course, ~.236 is set in recv.ini too.

I did not check the dexatek driver version right now, and now it's rather time
to perform a personal axis conversion from upright to relaxed, but I'll check
that tomorrow.

Everthing else seems to run fine. I have deactivated the Skystart PCI card in
the hardware profile for the time being.

Cheers,
U.
Ulrich,

DVBreport.exe tries to set the following parameters for the LNB:

symbol_rate := 27500;
frequency := 11977;
HV := 1;
LNBvalue := 10600;

and if it's returning sensible values for strength and quality it would appear to be working correctly. I'm using it here on two systems:

1 - PC Gemini, Windows Vista 32-bit, SP1, running Dexatek software
where DWUSBAPI.dll in \Windows\System32\ is:

589,824 bytes
Modified: 18 May 2009 at 16:09

2 - PC Alta, Windows-7 64-bit, SP1, running DVB World
where DWUSBAPI.dll in \Windows\SysWOW64\ is:

585,782 bytes
Modified: 19 Dec 2008 at 17:55:28

Neither versions contain version information. However, on system (2) there is a DC block in the LNB feed path, so any wrong polarity or high/low band settings would be ignored.

It sounds as if the release device control function in DVBreport.exe is upsetting the USB box, so I would remove those lines from the MRTG config for now.

Or is it all OK now? I see good data from 08:36 UTC (incorrectly shown by MRTG as "09:36 GMT") here:

http://eumetmon.rummelecke.de/skystar_windbuedel_snr.html

Let's get the missed packets down as the first priority.

Cheers,
David

Receiving again! (was:) Re: Geo usb2 box

Ulrich G. Kliegis
 

My sincere thanks go to all kind souls who spent their time and brain power
and shared their knowledge! Data are flowing again, now through the
Dexatek.

The mrtg configuration does still need a few once overs and taps, but after
installing the working, seasoned drivers, everything went smooth. Strange
that this buggy driver syndrome hit me the second time in a few days, after
the bad mrtg version event. Now, three knocks on wood (my forehead), that
this stays stable. I've still got the feeling that El Toro needs som re-
adjustment for the elevation, but that's something for the next days.

This was the final key:
ftp://ftp.eumetsat.int/pub/OPS/out/user/EUMETCast_Eurobird_migration
/

There are instructions for updating the Dexatek files.

Cheers,
Ulli.

Arne,
thanks for your ever-present readiness to help. I found on one of the CDs I
got with the dexatek box an installation software from 2008, the other from
2007. Both, however, do not know yet about Eurobird 9 and it's TPs. Hitting
"Satellite Update" in the setup window results in a blank list.

The sat list was in the V 3.0 setup. Is it compatible, or do you happen to
know how to teach the dexatek environment what and where EB9 is?

Thanks in advance!

Cheers,U.

Re: Geo usb2 box

Hello Ulrich, David and Ian,

I had lots of issues with V3.0 DVBworld drivers on my Win7 x64 test PC. I now only recommend to use V2.0 driver dated 20080415 !

All newer drivers/software contain goodies for TV watching and smartcard access but did not help in getting data running reliable.
That is why GEO shop (Clive) ships the receivers with a GEO CDROM containing the best drivers, EUMETCast settings and guide.

Dexatek and DVBworld are the same inside but unfortunately Dexatek stopped supporting their box (I cannot find updates on their site).

The old DVBworld driver isn't available for download anymore but I will send a link to Ulrich off-list later.


About removing Tellicast first, on my test PC this was not required. I have installed the DVBworld drivers and software more than 6 times (to find the best working version) and never reinstalled Tellicast.
I can switch between my DVBworld and Skystar any moment now by setting correct transponder and changing recv.ini.

But apart from assigning a different IP like .239 you will have to adapt your firewall (and on Vista you may need to adapt your route) too !
I guess that Tellicast setup may do this for you automatically.

More about twinsat LNB later.

Greetings,
Arne van Belle

There is one close spaced dual-LNB on the market, but it has to match the
geometry of El Toro very closely. I remember that they recommend a single
LNB with multiple outputs for satellites spaced less than 2 degrees apart.

There must be still another reason for the installation stall of the DVB
software. I tried it this morning on a different PC, and it stopped at the same
point. I had the dexatrek box installed there with a software version that
came with it - no idea what version.

Hey, no wonder the PC stalls. What can you expect from an in-stall-ation?

Perhaps you can get your in-stall-ation UP by DOWN-loading the current drivers:

Whut??? We have the first real spring weekend here, sun, 10 centigrades

We had that last week. Don't worry, it won't last!

Thanks, David, for taking the burden of demembering my PC totally right
now. I understood your mentioning of Arne's expansion also as a - should
work - go! Geocast is coming from 10�, so, I looked for twin output LNBs
already.

You guys have some thumbscrews to make people subscribe to your GEO
Mag... :)

Looking ahead (your splitter-setup etc.) - woudl it be wise to have a quad
LNB right now for Eumet- and Geocast? More ummmpphhh?

There are no driver debris and remainders listed - also not in the "show-
suppressed" view. I did something that looked and felt like installing the
DVBNet-driver, but the box still shows up as an audio/video device. Route
Print does not list it either. Some times, I ask myself, is it windows, or me?

Supporting GEO is important as it is the only active organisation left representing Amateurs, they organise quite a few events, and GEO has good contacts within NOAA and EUMETSAT to ensure that the amateur voice is heard, so I make no apologies for inviting people to join - in return for which they also get an excellent Quarterly magazine. Anyone in the hobby should be in GEO:

http://www.geo-web.org.uk/

Don't wait, join today!

It's Arne van Belle's setup which is described in the GEO Quarterly, not mine, but I do have a quad-output LNB ready for my next LNB upgrade. Despite having DC blockers and a DC-isolated splitter (won in the raffle at a recent GEO Symposium), it's annoying when taking down one of the master PCs (controlling the LNB) that the other PCs being fed from that LNB also lose signal, so a quad-LNB would be an improvement, and ideal for your case if you are going for the single, larger dish EUMETCast/ENVISAT solution Arne presented. Note that Arne uses a different arrangement - a close-spaced LNB pair with his Wavefrontier toroidal dish. But other than having two or four feeds, a twin- or quad-LNB would offer no other advantage.

The device having an IP address, and yet not being listed in ROUTE PRINT puzzle me. I wonder if the IP address is really the one for the SkyStar card? I might be inclined to physically remove it.

David

That has certainly not been my experience David. The first two times I
swapped over my Dexatek and SkyStar receiver with Tellicast still loaded I
could not get them working. By removing Tellicast and then re-loading it,
all was working after changing the IP address to fixed. Now if I am
changing the receiver I will remove Tellicast at the same time.

I do agree that the e-token software will be OK.

I had some snow here this morning but it did not lie and it is now turned to
rain. One of the benefits being at the coast.

Regards
Ian.
That sounds strange, Ian. I presume you had stopped TelliCast while changing over? It will be interesting to see what Arne's comments might be (they are at a Ham Fair meeting today).

Snow lying here, a depth of 3-5cm, but with the sun trying to come out, and +4.5C, I hope it will soon be gone. Rain in Barcelona for the final day of F1 testing.

There /should/ be no need to remove either the eToken software or
TelliCast when changing between SkyStar PCI card and the DVB World box.
Just changing the IP should suffice, as Ulrich says. Of course, if you
are having problems, then perhaps there are remnants of installations
which are interfering, and then a clean start might help.

Quite a lot of snow here (180m AMSL) and it's coming your way!

Ulrich,

Just a small point but when you changed over to the Dexatek box I assume you
removed Tellique as well. To be safe if I am ever changing a receiver I
also remove the EKU software.

If you simply change over a receiver with Tellique installed you will have
problems, you must start from scratch and install the receiver before
Tellique and EKU software and remember not to have the EKU
installed when loading its software.

Regards
Ian.
Ian,

You /can/ run both a SkyStar PCI card and a DVB World USB box at the same time - see Arne van Belle's article on page 12 of the latest GEO Quarterly Q.29. Not a member of GEO, you can join here:

http://www.geo-web.org.uk/join.html

and get the GEO Quarterly sent to you regularly. Arne also covers a novel twin-sat LNB concept for those wanting both EUMETCast and ENVISAT from the one dish. Lots of other really good articles as well.

There /should/ be no need to remove either the eToken software or TelliCast when changing between SkyStar PCI card and the DVB World box. Just changing the IP should suffice, as Ulrich says.

Silly question: when you installed the drivers for the box, you did

Re: Geo usb2 box

David J Taylor GM8ARV 🏴󠁧󠁢󠁳󠁣󠁴󠁿 🇪🇺
 

David,
I got pretty far tonight, although again not without some obstacles in the
way, and I am not yet quite there.

Hardware: i-Tek Sphere.
The installation software (incl. driver) on the included CD, started from their
menue, stalled at the time of driver installation (installing drivers, please
wait.... endlessly). The same with the V3.0 software from DVB World.

Uninstall everything, start over again. New hardware found, manual
selection of the DVBS2102USB driver. Driver installation runs through, I'm
Mr. Happy, until - the box appears as an Audio Video device now. Now
install the software only (V. 3.0 from DVB World again), it misses the audio
part (no wonder, I disabled onboard-audio in the BIOS when I set up this
PC, keeping it slim). But it starts, I can configure EB9, have to add all PIDs
manually, 'Testbild' appears in the programme list (this confirms that the
LNB looks at the right spot), but there is no image. Probably because of the
missing audio. No data taffic either, though. Quality about 82 %, strength
about 72%.
Start IP is refused - a warning dialogue (well, monologue): There is a
problem with your DVB interface...
Now, the USB Box is listed as a network device. Setting the IP to
192.168.238.239 (and ~237 as the alternative address) does not help. The
Technisat-card is still in the PC, but the antenna cable leads from the LNB
to the USB-box now.

Any idea, anybody?

Still XP Pro...

Cheers,

U.
Ulrich,

If Testbild is found, you are well on the way. Correct that it has no image or sound. You could have configured PIDs etc from the EUMETSAT EB9A update from their Web site, but perhaps it's no longer available for download. But it only saves a few minutes. I haven't had your problems with drivers, but it's been a long time since I did an XP install with that box - it's either been Vista or Win-7. But I did have a Dexatek or DVB World box on this XP Pro SP3 PC once, so it does work, as you've found after your struggles.

Silly question: when you installed the drivers for the box, you did install the DVBnet drivers as well? I /think/ we have mixed drivers and software from Dexatek and DVB World before, but I'm not sure. On this PC here (which hasn't been used with DVB boxes for a while) I have:

C:&#92;WINDOWS&#92;system32&#92;drivers

07/07/2009 17:06 34,328 DVBNet.sys
08/05/2008 19:33 49,024 dvbusbs2102.sys

C:&#92;Program Files&#92;DVB World&#92;

08/09/2009 23:09 999,424 DVB World.exe

I think you must have the DVBNet.sys driver installed otherwise the box wouldn't appear as a network device. It's not impossible that the lack of on-board audio is the issue, although dozens will probably come back and say is doesn't matter.

It does sound like a network settings issue - I can only suggest checking again. Perhaps even removing the TechniSat card (and noting which slot it's come from).

Oh, one other thing, if you have had multiple attempts there /could/ be a device which is not showing in the Device Manager. Check the "Show hidden devices" option. Also, see:

http://support.microsoft.com/kb/241257
or:
http://www.go4expert.com/forums/showthread.php?t=4229

which explain how to show "not present" devices, as well as "hidden" devices. However, usually those non-present devices simply stop you choosing the IP address they were using.

I hope something there helps!

Cheers,
David
