The benefits would be: Remove potential interference from the PI Remove doubt as to whether the receivers were fighting over a SWM channel issue Get your installation up to "code" Allow you to have it setup so there is less overall "loss" to receivers by removing that 8 way. Rule out everything else to isolate if it's a bad receiver before swapping it out. Add second tuner capability to your R16 (I know it's not very important to you) Also it would be needed in the future for any expansion. Which is another reason I think that they should have done this already. 771a is the receiver not seeing the SWM.
