It was the focal distance - and turned out to be a pretty important adjustment in my case.
I am now getting in everything with an average balanced signal quality at or above 70% for nearly every channel, with the highest transponder hitting 85% (only one low transponder coming in at 58% SQ)...Thank You for your help on this issue!
I had to move the LNB focal distance to the shortest possible (adjusted all the way in toward the dish). I never considered trying this before, as I read somewhere - either on this forum or on Glorystar materials (not sure which) that this is 'wrong' positioning of the LNB (and should be mounted in the bracket furthest from dish, not closest..). Since this worked when I tried it, I thought maybe my dish elevation was off, so I pulled the LNB back, and tried readjusting the elevation - NOPE, same low signal quality again. I readjusted the LNB back to the shortest focal distance again and fine tuned the dish, and first repeaked my signal quality for for channels: 901, 106, 113 - and then went on to peak the signal quality for 107, 120, 123 - to peak the problem transponders. I went back and forth with these six channels until I got the results - Rock Solid SQ! I never got strong SQ when fine tuning with the LNB at the long focal distance...go figure...

Glorystar Support - I have one additional issue. I am not able to get the Ant/Sat function to switch between my Satellite input and the incoming coax Ant input (DVD player). I tried hooking up other equipment to the receiver ANT coax and still had the same problem. I think it may be the remote, as the zoom function does not work either, or goes glitchy. The zoom is no big deal, but the Ant/Sat input select is pretty important to me.
Does this sound like something with the remote IR? Or does it sound like receiver firmware/hardware (internal A/B switch)? Is their a way to reset the remote IR with the receiver to test the remote - or test the receiver A/B switch by manually selecting the Ant/Sat function from the receiver panel?
