I have a 3x4 multi-switch on port 4 of the diseqc. The 3x4 is so I can use both H and V on the P* LNB. I just hooked this up tonight. It got ONN on 74w, but after that, I tried pointing at AMC9, and then Galaxy28, with no signal whatsoever on either bird. I can usually repoint successfully in less than 5 minutes. This time I was out there for over an hour. Did the 3x4 blow out port 4 on the diseqc or what? I'm not sure what's wrong, but it's not getting any more of my time tonight!
