Can an Apple I-Mac connect to a TV via TBS-6903 using DVB Dream or DVB-S-2 using Elgato eye tv /Virtual Box ? Just guessing  need help. Or do I need to buy a different brand of computer to make this work? Trying to get CBS/ABC on computer and forward to TV.

Tried to get the 4K football feed (Miami Oh and Iowa). Scanned in ok but when I went to watch with DVB viewer, it said no device available for dvbviewer. Then, when I tried again, it was just fine. Software glitch?  Time to process?  got me worried for a minute. 

Nvidia GEforce 1050Ti, tbs 6903.. Windows 7  64bit dual core gzh.. Just looking to see if anyone else experienced that.

I had successfully cross-compiled v4l-updatelee 4.20.0 for my Raspberry Pi 3,
I will list here the pros and cons of using it.

DVB Software  : Enigma2 - blindscan-s2 - blindscan plugin
DVB Hardware : Technisat Skystar USB HD

4097_0_1_0_0_0_0_0_0_0_20190915211411.jpg 
Pros:
- SNR measurement is displayed properly.

4097_0_1_0_0_0_0_0_0_0_20190914195004.jpg

Cons:
- Some Tps which works fine using the stock kernel doesn't work anymore after switching to v4l-updatelee 4.20.0.

For ex:
Frequency 10834V on Hot Bird 13E

Seeking latest opinions/recommendations for DVB-s2 USB (or even PCI) device

Hi All,

I was going to pick back up on my feed monitoring projects and went to screw in the coax onto the F-connector on my TBS 5927 and found that the F-connector barrel was detached from the frame of the PCB mount   it was just spinning in place and if I kept turning it would have broken off the internal wire from the center conductor.

I'll probably get a new connector and solder it on, but I'm also tempted to grab a new receiver if there is anything better (will still fix this one, but could use it secondary).

What I'm looking for is (some combination of) what is best supported by the crazycat and/or v4l drivers, what has working hardware blind scan (tell box to scan a range and it does it internally and reports back rather than relying on software directing it to tune and step through symbol rates manually).

Primary OS I would be using it in is linux, and would probably need open source drivers because I may try to run this from an Arm based Single Board Computer (Khadas VIM3) where I will need to compile the entire OS.

Ability to lock low symbol rates would also be nice, I also like trying to find interesting data and radio feeds.

I have had a lot of trouble with a 240cm fortec star dish and C2-PLL LNBF on a lot of broadcast feeds that seem like they should be plenty strong (I forget what exactly, they were 30Msps HD feeds I think..) .. so wondering if that was a lack of sensitivity in this receiver. I did have a fairly long cable with an inline amp I finally put in between which didn't seem to help much .. I will likely upgrade my coax soon, and if all goes well finally get a much better C-band dish, probably a 12' mesh on H-H motor.

Thanks for reading!

Mike

TBS 5520 and G17-Ku- 11740 and ATSC?

October 9, 2019, 8:08 am

I recently ordered a TBS 5520 from Rick, and today I hooked it up to try, and have a couple questions.

First question is, when I ordered this receiver, from the specs, I saw that it had a separate input for non-USA terrestrial OTA, so I assumed that it would not do USA style ATSC.  However after installing the receiver, I ran the change-mode program for it, and it lists ATSC as an option. Is this receiver actually capable of ATSC??

Second question, since I already had G-17-Ku-V tuned with my PROF-7500, I ran the passthru to new 5520, and did a blind scan.  It locked about 19 transponders on the vertical side of this sat, ie virtually every transponder that showed up on the Crazyscan scan, except for 11740.  It looked like that transponder was about 40 MHz wide, which should be within the 45000 SR limit of the receiver.  When I'd click on that peak, Crazyscan would not show a constellation diagram for 11740, but instead would think for a while, then lock on the 11784 transponder, which is strange in itself because I had the search range on 3 MHz.  I then tried to lock the transponder on the PROF-7500, and it did not jump to 11784, but gave a constellation diagram on 11740 which looked like a completely uniformly filled circle.  From the constellation diagram with the PROF, I thought that perhaps 11740 is something like 32 APSK or higher, and I just don't have anywhere near the S/N to lock it.  I thought also that it might be DVB-S2x, since the scan showed steep sides.  The 5520 should be able to lock S2x, although perhaps the transponder had a higher SR than I estimated?  Or perhaps it's in some other unusual format?
   So my question, does anyone know what format the 11740 transponder is in?
    EDIT1:  Never mind on this question.  I finally did what I should have done before posting, ie looked in Lyngsat.  Apparently 11740 is a Hughesnet internet transponder, so no wonder I can't lock it.  But it's still strange that the 5520 just jumps to 11784 when trying to lock.
   

  I'm going to try a few more satellites to see what I can lock with this receiver, but eventually I may hook up an OTA antenna to the other port, and see if I can get Crazyscan to scan a spectrum in one of the terrestrial modes.

    I'm also curious whether anyone else is using a 5520, and how it is working for them.

EDIT2:  Oh, and I'm still using Crazyscan ver 1.0.2.148 .
Would I need a newer version of Crazyscan to access the full capability of this receiver???

TBS-5520 blind scan and other issues

October 12, 2019, 5:37 am
$

As mentioned in another thread, I recently bought a TBS-5520, mainly to be a backup since a couple of my other computer receivers have begun to fail. My 5927 is still working OK, but my 6903 has lost one port completely, and the other port has lost it's LNB power, which I repaired by running it through a Tru-Spec power inserter, which works fine except that I have to manually flip a switch to change polarity.  Also, my Prof-7500 had failed, but then came back to life, failed again, then came back to life again.  Also, my two 6925 receivers both failed completely.  Anyway, I needed a backup.

    After playing around with using the OTA port of the 5520 as a crude spectrum analyzer, I went back to normal sat viewing, and I must say that the receiver is doing strange things, some of which turned out to be expected, but some I haven't figured out yet.
  The first thing strange was that the Crazyscan spectrum display looks very crude.  I'm assuming that the tuner or BDA procedures on this receiver aren't as sophistocated as those found on other TBS receivers. There are lots of flat spots (both tops of peaks and baseline) suggesting that the RF signal reading doesn't have much dynamic range or something.  Using the newer Crazyscan/streamreader versions Crazycat suggested helps a bit, but the spectrum still looks crude.
  The second issue is rather strange.  Since I generally use Crazyscan to select transponders to play, I found that if there are several relatively low SR signals nearby, if I select one of the signals, it will end up tuning another nearby transponder.  For example, on AMC-21 horizontal, there are 5 SCPC PBS transponders on TP-23 at 12145, 12155, 12163, 12169, and 12175.  If I click over the 12175 peak on the Crazyscan spectrum, it pulls up the 12163 transponder. If I tell it to tune the 12163 signal, it pulls up the 12155 transponder.To tune to the 12175 transponder, I need to tell it to tune to around 12180 or so.  And before anyone suggests that it is because my LNB is off freq, yes it is, but I have compensated for that by adjusting the LOF, and it behaves the same.
  Related to the above, the third issue was blind scan. I first tried the receiver on G-17 Ku, and was initially happy with the blind scan since it found all the Ku signals on that sat except the Hughesnet signal that it shouldn't receive.  However trying blind scans on other satellites revealed some strange problems.  I tried scanning the horizontal side of AMC-21, which only has the above mentioned SCPC PBS signals, along with a bunch of signals in modes that aren't viewable by consumer systems.  On my first attempt, the 5520 came up with nothing at all.  With Crazyscan, I then specified a range that covered only the TP 23 range, ie around 12140-12180.  When done that way, the blind scan quickly came up with the 5 PBS transponders.  So scratching my head, I went back and tried the full scan again, and again NOTHING was found, however I then realized that actually the previous scans had never completed because the scans seem to take forever. In one scan, I let it go for more than an hour, and it was only a bit more than 1/3rd through the scan, so it was never reaching the area where the SCPC tps are found.  When I'd scan using my 6903, it would find 11 transponders, ie the 5 PBS channels and 6 ACM/VCM generic stream transponders. The ACM/VCM generic stream transponders cannot be locked by the 5520, but apparently are severely interferring with the blind scan function of the 5520.  When scanning via either Crazyscan or a version of Crazycat's BLSCAN program, you can observe blind scans going along at a normal rate until they encounter a signal it's not capable of locking, at which point it slows down to a crawl. 
   At this point, with Crazyscan, I decided to only scan from 12060 to 12180 and then do a blind scan, chosen so as to include an ACM/VCM signal at ~12086 and the 5 PBS signals.  On doing this, as expected it proceeded very slowly through the ACM/VCM generic stream for a while, but then skipped over it all the way up to 12145, then at a more normal slow pace finding 12155, 12163, and 12169.  However the strange thing was that it then seemed to get stuck trying to find 12175.  It would get up to a freq just above 12175, then give up, and jump back to ~12163, then work it's way up to 12175 again, fail and jump back to 12163, over and over.  At one point I let it try for about two hours, and it never finished.  I then tried a version of Crazycat's BLSCAN, and it would scan through the first four SCPC transponders, and finish up missing the 12175 transponder.  This was before I did the test described in the 2nd issue above, ie that in order to tune 12175, you apparently need to tune well above 12175, or it will jump back to 12163.
    As it turns out, these symptoms are not a problem with medium or high SRs, as long as you click at a freq higher than the actual freq, and the blind scan will work on satellites that don't have transponders that the 5520 can't tune.  However it could prove to be an adventure to tune specific transponders in an area with several neighboring transponders. 
    I then wanted to see what the 5520 would do with TSREADER directly, ie not going through Crazyscan.  After finding the TSREADER source for the 5520, I gave it a try, and much to my surprise, it worked perfectly typing in the actual freqs/SRs even ignoring the fact that my LNB was ~2 MHz off.
So I'm happy that there should be no issue tuning most transponders with TSREADER.  But at this point,  there seem to be significant issues with the 5520 on Crazyscan. Not sure why TSREADER works fine, but Crazyscan and the Crazycat's streamreader based BLSCAN have problems.
   I think the next step is for me to try a few other PC programs, to see how they behave.  I should have 2 or 3 other programs on my computer if I can find them.
    I'm wondering what programs other users of the 5520 have been using?  There must be some other users on the list since Rick was out of stock temporarily when I ordered mine.
    Anyway, since it works with TSREADER, I'm not unhappy with the receiver, and I'm guessing that perhaps an upgrade to streamreader.dll might eventually fix all the issues.  It's actually fun experimenting with it's quirks. 😉

Streamreader.ini ? what is Frame Mode ?

October 19, 2019, 6:07 pm

  For the past couple days, I've been experimenting with a few things, such as DSS on PROF and TBS receivers, and had been changing a few parameters in the streamreader.ini in the Crazyscan directory.  Today, I tried to lock a DVB-S2 transponder on my (half broken) TBS 6983. The Crazyscan spectrum looked fine, and I locked a DVB-S2 signal with about 14db signal, however when I'd stream to TSREADER, I got nothing but gibberish.  I looked back at the lock on Crazyscan, and although it was 14 db signal, I was getting a very high BER, which seemed strange. I tried re-booting the computer, but that didn't help.  So I assumed that my 6983 had completely died, and switched to my PROF-7500.  Pretty much the same thing there.  Switched to my 5927, and same thing.  I only had one more modern receiver left, my new TBS 5520, so I crossed my fingers, and tried that.  Worked fine.  Actually all 4 worked on DVB-S QPSK transponders, it was just the DVB-S2 8PSK signals that weren't working.
    But why would 3 of my 4 receivers just stop working on 8PSK all of a sudden.  I tried all sorts of things, but couldn't get the first 3 to work.  I had assumed that Crazyscan and TSREADER were OK, because they worked with the 5520.   But eventually, after a couple hours, I decided to look at Streamreader.ini, and I noticed that I had left a couple of the parameters in the mode I was testing, ie the DSS and the Frame Mode.  So I commented out those two settings, and sure enough, the 6983, 5927, and PROF came back to life.  I assume that it wasn't the DSS setting, since previously, I had left that enabled with no problems, so I'm assuming that it was the Frame mode setting that caused the problem. 
  I have no idea of what enabling Frame mode does, and why does it kill 3 of the receivers but not the 4th? Could it be that the 5520 doesn't have a frame mode to be enabled?
   In any event, I'm really happy that I hadn't killed those 3 receivers, but don't understand what happened.

two transponders on G3C-V-C-band

October 21, 2019, 8:04 am

Wasn't sure which category to put this in, but since observations require computer, putting it here.

I think I may have seen one or both of these before, but didn't trust my reception until leaves started falling off trees.

First transponder is approximately at 4195 V.  On my 6983 and 5927, I cannot lock it, however the constellation pattern in Crazyscan shows a square 4x4 pattern of 16 spots, that I assume is a QAM signal.  Since my 5520 is supposed to do QAM in terrestrial modes, thought that perhaps it might somehow be able to make some sense out of the signal, however not only does it not lock, but the constellation pattern just looks like a square but random pattern.  Anyway, just curious if anyone else sees the same thing and might have an idea of what it might be.  Just curious.

Second transponder is at 3832 V 17138 Ks 3/4.   It locks with 12 dB showing CCM and transport stream, so there should be plenty of signal there.  However, when I stream to TSREADER, it shows tons of errors, and thousands of PIDs.  It must be in some strange mode, or possibly it's in generic stream mode, but isn't identifying as such.  Again, just curious what other people are seeing on this transponder and what it mode it might be in.  Just curious as it's not common to see a strong CCM TS signal showing just gibberish.

Just as the header says. Has been working fine in DVBDream but can not initialize hardware wehen trying to use stream reader. BDA works fine, but of course no blind scan. Have uninstalled and reinstalled drivers and DVB Dream same problem. Works fine with EBS Pro. Any Ideads how to get stream reader back in Dream?

dvbsnoop, cygwin, etc ???

January 20, 2020, 12:45 pm

I used to use dvbsnoop on an old computer that I don't use anymore, ie an old  Windows XP computer which had cygwin installed.  I also had a linux version installed on an old RPi that I don't have running right now.
  Anyway, I tried to install cygwin on my current laptop which has win-7 on it. I went to the cygwin web page and download an install file which when I run it, it gives me page which is supposed to have download sites, but there are no sites listed, so I can't get past that page.  I then decided to try to install it on my current XP computer. Downloaded the install file, and it gave me an error saying that cygwin wasn't supported on this version of windows. I tried both the x86 and 64bi versions

   So I gave up with cygwin and decided to try to install on the RPi 3b running Arch Linux.  I tried to find dvbsnoop using pacman, but it said that it couldn't find the program.
    Strange.  It's almost like dvbsnoop doesn't exist anymore or something.

Anyway, I started up the OLD XP computer that had CYGWIN and DVSNOOP, and it still works, but I'd really like to get it to work on either my win-7 or the newer XP computer.  The OLD XP computer is a home edition laptop, while the newer XP computer is an XP Professional both SP3.  I'm going to look through the old computer to see if I have an old installation file there.
   Anyone have any idea why cygwin wouldn't install on my newer computers?

EDIT:  Sorry, I should have tried this before posting question, but I just copied over the whole CYGWIN directory from my old XP computer to my new XP computer, and it seems to work without actually doing any installation.  So maybe I'm all set.  Haven't tried it on a binary file yet. but it looks to be functional.

need VLC help

  I've been using VLC for close to 20 years, but primarily for playing files or via streaming to/from TSREADER and/or other computers.  But I now have a need to have VLC use my BDA DVB-S2 tuning cards as an input, and I just can't seem to get it to work.  I seem to remember having this problem years ago, and I can't remember if I ever got it working or not.

  Anyway, for my attempts, I've been going to Media/Open Capture Device, and entering what I think is the appropriate parameters, but I keep getting failure errors, as shown below:
vlcbda.jpg 
I have tried tuner cards#s from 0 to 5, but none will work.
I've tried adding and removing "000" from the frequency and symbol rates, but same errors.
I've tried using the raw IF LNB freqs instead of the actual freqs, but same results.
I've tried several things in the "Advanced Options", but gave up since that doesn't save parameters.

Anyway, can someone see anything I'm doing wrong? 
Or, can someone suggest a command line including the call to VLC that they use to call a DVB card??

thanks

34.5W/180E French Transponders TS Dump

February 12, 2020, 2:01 pm

Hi everyone, new poster here! A bit of a long shot, but here goes -

I'm interested in a couple of France Télévisions transponders on 34.5°W and 180°E Ku Band. These provide the backhaul for digital terestrial (OTA) TV as well as mainland French public radio in the French overseas territories. I know most people on this forum are located in the US, and two satellites that carry these feeds are receivable in parts of the US. I'm in Europe and outside of the footprints for both!

There are two transponders carrying these feeds which I'm hoping some people on here are able to receive - 

34.5°W - 11594H 30000 2/3 DVB-S2 QPSK - with feeds for the French Caribbean (Martinique/Guadeloupe/St Martin/St Barthélemy/French Guiana) - this one is on the Caribbean beam of Intelsat 35e which looks easily receivable on dishes under 1m (3ft?) in diameter pretty much the whole way up the Eastern half of the USA.

180°E - 11155V 28588 3/4 DVB-S2 8PSK - with feeds for French Polynesia - this one looks easily receivable in the Western USA, especially over California as it's on the "Polynesia + US" beam.

I'm just wondering if there's any chance anyone would be able to record a TS dump of either of those transponders for me? Just of a minute or two of the complete transport stream.

Basically I'm interested in what ancillary data is provided over these links; I've always been curious about these TV/radio backhaul feeds between mainland France and the overseas territories.

I went to Martinique last year and found it pretty crazy that in the middle of the Carribbean you can listen to France Inter on an FM radio with identical RDS data as goes out via the FM network in Paris.
