http://www.newtec.eu/frontend/files/userfiles/files/Whitepaper%20DVB_S2X.pdf

If it is DVB-S2X and it requires the PLS code to be set, then I have a lot more searching to do.

Also, the TBS 6522 isn't compatible with all flavors of ACM/VCM signals.

If the signal is DVB-S2X and ACM/VCM, then that could be why I can't get a lock.

It's a mystery signal, that's for sure.

Yesterday using Transedit to analyze this freq. a audio pid showed but nothing played and just now try again video pid popped up but no video. Is it possible this is like a sat ip in some other form. Does seem to change a lot starting with different numbers also at times numbers come very slow at other times boom rite away.

I didn't not have a lock use 6925 here just used transedit to analyze also Smartdvb you are onto something for sure seem funny 1 time 13.1 next time 12.? like there switching from there leave it to you experts.

Edit:I went back down to check 13.8-9 to 14 db better than yesterday maybe a little short on signal when it goes to 14 may be when I catch video pid. I was able to see 3  times a video pid always with a different number 1 time came the numbers for 101 nasa 101 being the video then 2 below show same audio as nasa.

Rather strange behavior with Transedit and TBS 5925.
I don't get a lock, but if I leave it open long enough, an occasional random pid will show up.  There is only one packet sent with each pid.

Fellow Members, your posts are welcome here! Do not worry about posting everything perfect. Different receivers and LNB's will give you different Frequencies and Symbol Rates. Some set top boxes, PCI cards and USB receivers, Do Not Require all of the same information that others may need. It is not Required to post everything that others may need to tune in a feed. It is just most important to share the find. We can always adjust the Frequency and Symbol Rates and try the various Modulations and FEC's on our own receivers until we get a lock and then give a polite reply with what works for your receiver, as that information might help others as well. We all appreciate the efforts and energy of the Posters!
