yes, those are the data carriers contained over the range of about 25 mhz.

My big Q is which satellite.  Seems too strong for AMC-2 C-band since these carriers have good signal strength when AMC-2 is furthest from its equator crossing, yet these signals seem too variable in strength to be ARSAT-2.  The signals change level over the course of the day by a little bit and you'd think if it's from ARSAT-2 that the signal strength should be very solid.   I suppose just for fun I should take a data carrier on a satellite like G16 C-band and watch it over the course of a day and see if it's usual for it to change in signal strength by about a quarter of a division on my spectrum analyzer screen like what I see from these carriers on AMC-2 or ARSAT-2.  Maybe a little bit of signal strength variability over a day from a solid non-inclined satellite is normal.

I was curious re just how narrow these signals were.  Pulled them up on my $15 SDR receiver.

Looks like a bunch of narrow signals which have about 200KHz bandwidth.  There were a couple with close to double that, but most were 200.  The strange look of the waterfall, was caused by me changing the freq. 

I doubt we'd be locking any 200KHz signals, but a 400KHz might be possible with the 6983.

arsat-2narrow-4.jpg 
The above shows the SDR tuned at around 1336 , which computes to around 3814.  There are a couple of the wider signals there.  Still unlikely that we could lock them though.

I used those sats for NFL too. I upgraded to Ku in 1990.

AFC on K2 was why I never upgraded to Ku. My first dish and feed are C/Ku, from 1986. The Ku LNB, long since upgraded, a 3 lb. beast fatter and taller than most C LNBs, Panasonic, 2.5dB, was bundled with the Chaparral feed.

Today, SES put in an application with the FCC to move AMC-2 from 81° W to 85° W. So ARSAT-2 will soon be the only satellite at 81°.

Also testing 3835 V 10666 S2: Argentina

TV Publica HD - was clear this AM but has gone to scramble
TV Publica SD - FTA
unknown encrypted

Hope this stays because we've seen the Dakar Rally before when on 40.5W (now channel gone from there).

I'm seeing these signals on the North America ku beam:

11807 V 21600

DVB-S2 QPSK
1/4 FEC
Pilot On
ACM/VCM

12162 V 42500
DVB-S2 32APSK
3/4 FEC
Pilot ON
ACM/VCM

There is a very wide signal on the horizontal side at:
11796 H to 11862 H
But I can't lock it.

Here is a link to the Arsat2 footprint:

There is a new mux on Arsat 2 at 81W.

3848 H 13500
DVB-S2 8psk
5/6 FEC
Pilot Off

Currently 5 channels
It appears to be similar to the mux that was on Anik F3.

Cnn Espanol
CNN
HLN
bein Sports
CNN International

There are other unknown channels in the PAT, but not in the stream at this time.

Video is HEVC  720x 240.

Did this just disappear? Had it at 72Q and then poof, nothing.

Yes it's gone.  BLSA shows no signal there at this time.

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!
