Are talking about the add-on's listed on the Titanium website? If so those are not required add-on's, they are suggestions for different situations. Also I have never seen a job where I needed every one. I have been a satellite dish tech for many years, and I carry all kinds of stuff on the truck. Every situation is different. Most of the time you install things and they just work. There are times however that for whatever reason you have interference or noise on a line. Most recently it was the fact that the dish was installed the next lot over from an AM radio tower, pumping out some serious wattage. Had to install bypass capacitors on everything! Other times just one or two caps here and there will usually do the trick. If proper shielded cable is used and only tied to earth ground on one side or the other, most issues are not there to begin with or will go away when done properly. These suggestions are suggestions that would apply to ANY controller and not just the ASC1. Just ask a buddy of mine that lives down the road, he is a retired C-Band tech. Installed thousands of C-Band dishes. He also taught me a lot of tricks that I never thought of. You have a very unique problem here. Hard to troubleshoot over the computer, and not knowing the whole story. If one of us could be at your house, we might see something that you would not even think about. Like a commercial transmitter near by or something.
