Thanks Dave. I know your pretty good at integrating the SMS/500 and I was trying to be succinct. Please chime in because I may have been too brief. One more thing I should have added, when you are done adjusting the SMS increase your delay for the 500 at the receiver by 5 ft more than the physical distance to your favourite spot (2.5ft for the chip in the SMS and 2.5ft for the chip in the 500.)
