Underfire, you do know what you are talking about? I think you are getting your NIC mixed up with your NUC and your HPL with your HFOM...go and have a read....there is a huge difference between running a TSO129 NUC/HFOM which IS affect by RAIM and TSO146 gear running HPL. This argument was done to death years ago with Leadsled and T28D.
