If I remember correctly since the 800 MGHz rebanding you have to change the frequency band plan in the settings when programming the BC996T. I had to do this for a Friend so his BC996T would work with Starcom21. My BC996XT could get the correct frequencies from the CC data stream. My BC996XT Scanner was bought in 2009 and did not reqire the change to the band plan. Here is a link with instruction for the Uniden scanners.

Thanks Vascar. I've been away a few days and appreciate your help. I have the 996T software open now and will try to Understand this and correct it. I assume the band plan is entered once under the Starcom21 system. Thanks again. Greg
