I am trying to repair a Cushcraft R7000.
It shows high SWR on all bands.
What could be the problem? 
I suspect the CT1 trap which is located at the bottom.
I guess there is a parallel resonant circuit
in the CT1. What is the resonant frequency?
And what are CT2 and CT3 resonant frequencies?
Could someone give me ideas?
