Giovanni,
One thing to mention, and I know that there may be differences between your Viewsat reciever and my Coolsat, but work with me on this subject as I will explain it.
When I am in the DISH SETUP menu of my Coolsat receiver and I am trying to align my dish to satellite 79.0'W, the receiver looks at the very first TP in the list within its memory. Unfortunately, this TP that is listed there is not an active one.
It may be a valid TP, but it is likely a FEED TP and not a consistent broadcast.
We have given you the 11.900 GHz TP as a guide (the one with KTEL channel on it) as a reference. This is a good TP, but you may have to be in a specific mode to detect this TP's signal. On my Coolsat 5K, I have to go to the MANUAL SCAN MENU and select TP 11900 to be able to detect its signal. If I am in the antenna setup menu, the receiver looks at a totally different TP (the one that is first in the list) and since that specific TP is not active, I never see a good indication of signal strength or quality.
Your Viewsat receiver is probably similar in this respect, so you should do your antenna alignment with the receiver set in the MANUAL or TP scan mode, and not in the antenna setup menu.
I hope that I am not confusing you in this regard, but I think that may be your problem. This scenario is true for a Coolsat 4k, 5K nd 6K receiver, but I don't have personal experience with the Viewsats (I believe that is the receiver you have).
Even if I am mistaken regarding your receiver brand, this is still something that you should investigate.
I just scanned satellite AMC 5 @ 79.0'W and I picked up KTEL, WWE KU BACKUP, CNN5.5 and all the NYN channels (10 of them).
KTEL came in on TP 11.901 HORIZONTAL (symbol rate 2.170) and has VPID of 0049 and APID of 0051 and PPID or PCR of 0049.
You might try for the NYN channels on TP 12.177 HORIZONTAL (symbol rate 20.500). These may be mostly encrypted, but are stong signals.
