I realy cannot figure this out!!! I have used the easier to read manual for the 996xt, I have also used the freescan software using the import trunked system from radio reference. I live in Rutherford county NC and the only police department using the viper p25 system is the town of Spindale. I've programmed there channels conventionally as well as digitally, tried the diffrent p25 setups ( p25 standard,single trunked etc.) and still hear nothing. Also it really shouldn't be a range issue I only live about 3 minuets away. If anyone has experience programming the viper p25 into a uniden 996xt please help.
