I'm not sure but would be curious to see what a up linker on this forum thinks.
Because one day I saw signal on my spectrum analyzer pop up and immediately
Tried to lock, and the constellation looked like that
Then about a minute later the up linker Musta gave it some power and the signal went from one spot to four.
( Qpsk) I cuaght the signal before they had set up things in their truck, I guess?
That's my best quess anyway of what those are or could be.

Definitely something odd about the signal.
Crazyscan takes over 30 seconds to even start the constellation diagram.

I can't say for sure, not an uplinker or satellite engineer. But on those signals where everything shows up in one quadrant, they look like something a guy might transmit to keep an amplifier happy while there is no real traffic.
Have seen signals like that in various places for years.

I can lock that one.  Sometimes it locks as 16APSK and sometimes as 32APSK.

lol, kind of. it's still 4k resolution. You can't pack more pixels at "ultra high def" as the same bitrate as a 720p web stream video. lol. Doesn't matter what codec you use. You need more bits for more pixels.

Both of these channels are on another mux on SES 1.  Not sure what they have planned for this mux.

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!
