Aren't we glad we do open review of concepts? This may in fact be a deal killer for our very lowest power desires for the SMS concept. In fact, the spin modulation may queer the entire deal irrespective of the antenna being on the spin axis or not. It will certainly be worse off the spin axis.
I will work out this out with Frank to get the numbers. DRAT. I knew there was something we were forgetting.
