I just acquired the 996xt and loaded up Freescan and programmed all the sites with frequencies and talk-groups for my area in NE Ohio but cannot get anything on the Ohio MARCS system. I have conventional frequencies working but cannot get anything else. I even downloaded from another 996xt with freescan the same MARCS system I want but when I put it into my scanner it still does not work. I am guessing there is one setting that I am missing but I have been all over the different settings and cannot get it.
