I have 2 CW600s receivers hooked up on first floor and a Pansat 2500a and a Pansat 3500s in the Basement one at Bar and one in a room in the Basement. Well my problem is when any 1 Cw600s is on with all the channels working on Echo 8.6 it well knock out all the premium stations on any of the other receivers but if I turn the CW600s receivers off both Pansat receivers run Great with all the Premium stations working but if you start anyone of the CW600s receivers up it well knock down the Pansat receivers with a weak signal on all the Premium stations. I am at a loss with this. Any Ideas People?????????????????
