These two data muxes on Horizons 2 look to be some type of DVB-S2.  But they lock and unlock every second or so.

11840 H 33000
11880 H 33000

SR is approximate.

What do you think about these two signals?

Anik F2
4000 H 28000
4160 H 28000

They seem to be DVB-S2, but I can't lock them.

I noticed the 4000 freq was there, then gone, then back, now its gone again. I can see both signals on an RF sweep, nice wide signals but the Prof 8000 won't lock onto either of them...are there still ntsc feeds on the c band side of that bird?

Both feeds are there now.  I haven't seen any NTSC in a long time.  Maybe an occasional lottery or hockey feed, but nothing 24/7.

My big dish is tied up at the moment, so I had to make do with something smaller. The CNRs of the 4160 and 4000 are too low for a reliable characterization on my available dish. In several scans I have seen these reported as:

32APSK, 3/4, Pilot On
16APSK, 8/9, Pilot On

I'm leaning toward the 32APSK, but that's mostly because it seems to happen more often on 4000, which has a slightly better CNR, here. There is a low rate one though:

111.1W
3954 H 1000, 32APSK, 3/4, Pilot On

Still stuck on a smaller dish, but the CNRs are getting a little better. The tuner is now more consistently getting partial locks with:

111.1W

4160 H 28000,  32APSK, 3/4, Pilot On, 0.35 Rolloff
4100 H 28000,  32APSK, 3/4, Pilot On, 0.35 Rolloff

Here is another one that causes my Prof 7500 to freak out.

Thats interesting Photoman, my Prof 8000 scans it as DVB-S2 qpsk but the constellation looks like 8PSK and in Transedit when analyzing, the signal jumps from 0-90 repeatedly......just like 16APSK signals. Maybe Pendragon will weigh in with results from his setup.

Its a windows blindscan program in development, I'm a tester. There are still some bugs..... not published yet.

grr windows, that leaves me out, Im anti ms. Either way though Im all in for supporting our hobby, even if I cant use the software, many will and thats a good thing

Is it only supporting the 8000 or the 7500 as well ? Not many 8000 owners out there, well not as many as 7500 users.

TBS has been working on a blindscan app for some time; there are a couple of threads on their forums if you're interested. I'm not the slightest bit involved with them, but they are working with the STV090x demods that also happen to be in the Profs. I've heard that the Prof tuners can also be made to blindscan with the TBS software, which would make some sense. From the looks of this display, they still have some things to iron out.

The STV090x demods have some engineering features built-in, including the ability to generate data for constellation diagrams. I did a quick test a year ago and I think I could get this to work on Linux. But as always, the S2API is not a good match for this.

My blindscan software is typing this as:

3954 H 17692, 8PSK, 3/4, Pilot Off

I'm seeing a CNR of about 13 dB on a 3m with some snow falling on it. That should be plenty for a solid lock, but it's not happening. The demod locks carrier, timing, FEC and sync until the cows come home, but it can't lock on the transport stream. It may not be there, or maybe the framing isn't what the demod expects.

Looks like Prof is getting ready to make 16 and 32aspk tuner cards available, if its not already out.

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!
