Never did get the long story. I added t= he cap, but I had multiple gremlins that all added to my problems. The CAS = wire was the last part changed as I worked through them 1 by 1. Each made i= t better so I would say all of them contributed to a better system.
Just seems RF is a bit of a black art. Fix 1 problem area t= hen it finds another way in.

Thanks Andrew.

So Tracy never explained the =E2=80=9Clong story=E2=80=9D?
Did you add the caps and did they help or not?
I=E2=80=99m thinking not, as you mentioned changing to a better shield to t= he CAS
