Port 4, is that the 4th port on the bottom?

He actually meant to say put it in the 3rd port.

Since there are only 4 or 5 local markets on 105 and not for you, I would not waste time trying to peak the SuperDish 105 for all 3 birds; but peak it so that 119 and 110 are strong, and then you will have less rain fade for 119/110.
Hopefully your post also had a typo

and the connections are:
- Port 1 = NC
- Port 2 = 119
- Port 3 = 129 (Instead of Port 2 also = 129)
Although it should work either way, it would be less headaches to
go ahead and swap the 2 cables between Ports 1 and 3, so that it is:
- 1 = 129
- 2 = 119
- 3 = NC
Then you will need to slightly turn the dish so that the LNBF arm is pointing 9 degrees more to the east (left from behind dishpan). That means -
turn the dish mounting bracket on the mast pole less than 1/8", i.e., try moving it about 1/32" to 1/16". Just before you start adjusting the azimuth, throw a heavy rag or aluminum foil over the dual LNBF (105/110). Then when the single LNBF picks up 119, it will be on the correct LNBF. Remove the rag or foil and run a check switch. You may have to run it a couple of times. And you may have to peak for both 119 & 110.
Then your 311 will show:
- 1 = 119
- 2 = 110
- 3 = NC or maybe 105.
With 129 & 119, you probably are not receiving anything on 129, and 119 is just giving you part of your subscription. With 119 & 110, you will get the majority, if not all, of your subscription.
