Hi, Have you tried to redo the calibration on the erratic subreceiver? It's now been a long time since I did this, but I had to do mine three times before it came out right. The 2 first times I had a dead zone like you do. It's very important to make sure the frequency is spot on as the instructions call for a very narrow bandwidth to be used.
