Dish Network 1000.2 / DVR 722 not seeing 129 satelite

[vt-grh]

I am having no success in aiming my 1000.2 with a DPP LNBF hooked to my Dish DVR 722. I receive adequately strong signals for satelites 110 and 119 (75+ on the point-dish screen). The check switch details shows the same information for both satelite inputs, as shown here:

Status: Connected to a DPP 1K.2 w/Separator, 4 ports

Port 1 DPP 1K.2 110 Even, Odd

Port 2 DPP 1K.2 Good Connection No Signal

Port 3 DPP 1K.2 119 Even, Odd

Port 4 External LNB: None No Connection

I use a Channel Master 1005 IFD to aim the dish, combined with the point dish feature of the receiver.

I am located in 05250 area, and have a very clear aiming location. I have about 120 feet of RG6U to complete the parts list.

My suspicion is that Port 2 should be receiving satelite 119 and Port 3 should be receiving satelite 129. I have seen other postings in this forum with similar problems but no follow ups to suggest plausible solutions.

Can anyone make a suggestion here?

Thanks in advance
