Hi all,
Well the issue ended up being the end of the arm I repaired. It was off center just enough to affect my horizontal polarity.
Once I removed the repaired end from the scaler and replaced it with wire tie the horizontal polarity returned

Now I just have to make a more permanent repair.
Thanks again so much to all of you who showed a concerted effort to help me solve this issue.
The only issue that remains is that I'm not getting the transponder 4180H 30000 on 101W. Guess I have to tweak that repair a little more. All other horizontal transponders are strong.
Thanks again.
John
