Glitching

[eastof111]

I was watching KTLA news this evening and noticed that there was glitching very similar to the Sundtek tuner on strong signal channels. Namely, a strong signal channel would glitch (KTLA), while other channels with the same signal strength (TVO and City) played perfectly.

Just an observation which makes me wonder if there is a ecm in the stream that might cause this.

My guess for you is signal interference, maybe from another satellite. I had to move my dish almost to 103W before I could get this mux, which could point to an interference issue, my poor dish system or both. My SNR is about 2db lower than yours, but I have a clear, glitch-free picture at the moment.

I can't get my solo2 to scan Ses 1 as it doesn't show up in the list of scanable sats even after I have it set up on tuner B. I also noticed that before a manual or blind scan, several of my c band sats are missing. Any ideas why? Almost seems as if my sat file is corrupted in some way.

Your sat file should be OK.

Post your settings file in etc/enigma2. Post this file ONLY if you have not connected to Facebook or any social media that requires a password using the Solo2. (May need to start a separate thread)

My bad, I was checking the sats on tuner A which I use for ku band. Stupid me, changed to tuner B and they are all there.

Same thing will happen if your satellites.xml file in etc/tuxbox Changes during an update. Be sure to keep up with the sat file that the receiver was set up with!

What about glitching on the 101 mux? Do you have any???

[Costactc]

No glitching issue on KTLA on my solo2 and excellent signal quality:

You can change the quality to db if you want to. The Solo2 will let you do that on most skins.

[Costactc]

How would I do that?

[eastof111]

Depending on the skin, usually, system>extended system>osd settings>settings>swap snr in % with snr in db.

In regards to the glitch, I just found it interesting that it almost replicates the same symptoms as with the atsc glitching.

My other channels on 101 are fine with no glitching. This was my first experience with a solitary glitching channel on 101 since I installed the bud.

As of right now, no glitching on that channel and the signal fluctuates between 12 and 12.2 db.

Thanks East. I found it in user interface-settings. KTLA is solid at 13.7db:

Can you guys check the signal strength with the latest drivers?

The overflow should be fixed already.

[eastof111]

Will load 2015-11-30 19:005:10 and leave it running/recording my usual over night station. Tomorrow will play with other stations to see the results.

Thanks.

It just runs up to 99 and does not go over that amount. SNR in db would be best, but it does not run over 99 percent now. I have many stations on one antenna showing 99.

Also, Glitching and audio chopping should be fixed in Vu+ images with drivers dated 12-1-2015. The foul play by Vu Was Not appreciated.!!!

[eastof111]

Where was the foul play by Vu posted?

Thanks, good to know.

The first set of pictures are of Vix in flash build v.023 dated Nov. 11, 2015 and Sundtek drivers dated Nov. 30, 2015.

126611266212663

Has minor video glitching and audio glitching and/or distortion.

The second set of pictures are of Vix in flash build v. 027 dated Dec. 01, 2015 and the same Sundtek drivers date Nov. 30, 2015.

Still minor video glitching but the audio problems have disappeared.

Third set is ATV in usb open multiboot v. 5.1 dated Nov. 12, 2015 and Sundtek drivers dated Nov. 30, 2015.

Still minor video glitching but the audio problems have disappeared.

Look closely at the last picture you posted. The drivers are dated 12-1.The Vu drivers before 12-1 are bad, down to about May. So you have several months of bad Vu+ usb drivers.

The Sundtek drivers for ATSC have not been changed in some time. As far as I know, the only ATSC change in months has been the recent signal level change which should only be cosmetic.

[eastof111]

I posted the last picture to show that ATV was updated on 12-02 and has the same 12-01 drivers as the latest VIX image and also has the video glitch as VIX. Now both ATV and VIX have the same 12-01 drivers and the sound has been corrected, but both images still have the occasional annoying video glitch.

[el bandido]

I have been using the Sundtek ATSC USB devices for many months and do not have the glitching issue you have unless the signal is being affected by weather. The ATSC market is small, so there is not a lot of users to compare information with. It is doubtful that you have a bad usb device but I guess anything is possible.

It would probably be best to contact Sundtek directly about the glitching, but the data that can be gotten from an internet website is very limited. Many developers are on Skype. A lot can be done with real-time communications set up on Skype, and a computer set up with Team Viewer. A combination like this gives a developer direct access to your equipment, and allows for tests to be made using your equipment. This is about the only way I know to look at issues with the developer and see if it can be decided as to what is causing problems. I know you do not like Skype, but it beats sending smoke signals, and it is real-time communications.

Glad to hear yours are working properly.

[el bandido]

Your device should be able to work properly too if you will take the time and steps needed to check it. Longshots are a bad driver or a bad device. The most likely problem for the occasional glitch besides changes in the atmosphere between receiver and transmit tower is a hardware issue between the usb device and antenna. If you are 100 percent positive that there is no hardware problem, and have taken all necessary steps to rule a hardware issue in the antenna system out, then capture the raw stream for 5-10 minutes and send it to Sundtek. It is doubtful that the driver is damaging the stream for you and not for me, but it could happen. Your usb device should be under warranty, but you might want to check all possible items before declaring it defective and returning it. Maybe even try the device on another antenna system besides your own?

[eastof111]

As mentioned in earlier posts, the current antenna system works fine with two existing tvs (dlp and led) and an old Sonicview. Haven't had the time to devote to contacting Sundtek to try and rectify the problem. If time eventually does permit, I definitely will.
