Don't give up!
Brotherhood -- Don't give up! Once you get your system running, you'll probably find that the solution to your problem was all along just one very minor adjustment away.
You really don't need a signal meter, in my opinion, since you have that function built into your receiver already! If your system is not set up properly, the world's best and most expensive signal meter won't help you one bit!
Probably everyone on this forum has, at one point or another in their FTA experience, suspected that their equipment was faulty, only to discover afterwards that they were not pointing their dish properly, had neglected proper settings for their type of LNBF, had failed to select an active transponder when adjusting their dish, or something similar.
If you're trying to lock onto AMC-4, it helps to know which transponders are ACTIVE when you move your satellite dish back and forth and up and down in search of signal quality. I haven't been on AMC-4 for quite some time, but I suspect that the following transponders are active and sufficiently strong:
Tp 11704, Vertical 2170
Tp 11807, Horizontal 2731
Perhaps someone else from the list can provide a better suggestion on which transponder to use when searching for signal quality...?
Do not use one of the 4-digit transponders (C-band) when you search! I'm not familiar with your receivers, but on mine, the C-band transponders are the ones that come up first, so I have to scroll down to one of the active 5-digit ku-band transponders.
If these transponders are not available in your setup, you can add them through your transponder manager in the receiver setup menu.
Double check your LNBF settings in the setup menu. Do these correspond to your type of Ku-band LNBF (standard, or universal)?
Have your tv screen in sight when you move your dish back and forth so that you can see when the signal quality pops up on screen.
AMC-4 is at 101° W., so you need to be pointing your dish over toward the 180-200° azimuth range. Use a compass to get a general idea where that is. Remember that the elevation marks on your dish and compass readings may be misleading: sometimes you'll need to turn your dish beyond, below, or above where you "think" the satellite should be...
(I noticed that one of your pictures shows a missing R-6 cable on your LNBF; I assume that's just because you had removed it... Silly me, if you are getting signal strength I guess that means the cable is indeed connected!)
Feel free to come back with pointed questions if the above doesn't help. The guys here are quite indulgent and tend to help until your problem is solved.
