If I understand you correctly you do not have the receivers tied together but are actually unhooking one and hooking up another everytime. Have you tried parking the dish on the same sat prior to switch? In other words before unhooking the receiver park the dish on G10R. Now when you unhook the other receiver do the same. An alternative potential solution would be to utilize the loop thru on the receivers and chain them together using only one to drive the dish.
