LA File
Here is a file for La Cty. It is a Freescan file, you can download Freescan if you don't already have it. The file is a zip file, so per RadioReference, it has to be zipped, so use any unzipping utility 7-zip is a good program to use. Some stuff in te LA area is already or about to go P-25 type II so the 396xt can not decode those. the 436 or the newest Uniden models do. The 396xt has a nations , by state, trunking systems for the Highway Patrols, loaded in the radio but all other frequencies you have to put in. Compared to the 436, its not a big difference.
