Doug,

I talk to him all the time.  If he has only his 900 my radio with him and no other radios on, and he connects his node to his 6 meters in the same box we hear an echo on our remote nodes.  When he does not have them linked together all is fine to us on remote nodes.  No, it isn't because he is listening to himself.

It should not matter if they are in sync since no one generally listens to both at the same time right?

Both operate just fine when separately to connected to another system but when I connect in the second node to the same system everyone hears an echo from me.  I do not have a reverse of that,  in that I don’t have an  echo when both are connected and I am just receiving.
