I've encountered some very strange behavior on IA6 Ku.
I have 3 FTA devices, 2 set-top boxes (DMT1050 and Globecast) and 1 Twinhan 1020A.
Using my DMT1050, I try to connect to IA6 Ku for TV Azteca. Of course, I'll try the stronger transponder first: 11864V, SR 3515, the one with the University Network. Lock this TP easily.
But when I try the TV Azteca transponder: 12076V SR 8741, I get very strong signal, but the quality stays at 50% (on the DMT, it means it's getting close but no cigar), no luck locking it no matter what I tried. Tweaking the dish, turning the LNB, nothinig.
Getting very frustrated (I've tried this for weeks), so I decide to try the same thing on the Globecast receiver. To my surprise, I can lock the Azteca transponder easily, but no matter what I do, I can't lock the Univeristy Network transponder, which is supposed to be the stronger TP.
So I try it on my Twinhan, same result as the DMT1050, lock on the University Network, no luck on the Azteca.
I try this without any DiSeqc switch, just straight LNB to receiver connection.
Now this is very strange. Does anyone have similar experience?
