Thanks for the info, and here is the state of affairs. I switched units and both cut out even on the sub. I noticed this one day while playing music and watching the red and blue light on the receiving unit. So I used a long cord to place the units in direct view of each other and it worked better but still cut out 20' away in direct line of sight. I do use an apple wifi unit and it affects my cordless phones quite a bit. Next week I am going to try it after shutting off the wifi. I am thinking this may be the problem in which case I cannot use them I guess. I will keep posting as things develop as this may also help others and OA.
