Yes. There are at least three programs that support the Uniden XT models (including the '396XT).
Pro96Com for decoding P25.
Trunk88 for decoding Motorola.
Unitrunker for decoding EDACS, Motorola, and P25.
You do not need to add a discriminator tap for these trunking modes. However, to decode other formats, you will need a tapped radio. If you primarily monitor Motorola trunking, you will be better off with a discriminator tapped radio. The decoded output for Motorola is poor under weak signal conditions. Performance is fine for EDACS and P25.
