Jay,
That's a very interesting point about the 4G puck....do you mean modulating
data over side-lobes? To your point, I as a subscriber would have no way
every knowing that unless of course I hooked up my specanny and started to
try to decode the sidelobes....I imagine most folks don't do that ( if
thats how one would even go about it )
