I'm using a 996 and 796, it doesn't matter. All the freqs are broadcasting data, with analog voice traffic. Highpockets: You should be able to hear this where you are. I did have the correct base, offset, and spacing (406.0, 380, 12.5) when there was only one freq with CC data, and was able to track it. This is not part of a Smartzone system, it's a single site on the Ft. Dix ranges. FYI, the system at Dix & McGuire is not Smartzone, there is only one site at MAFB.
