You would need to get some software - and the choice of software is dependent on what scanner you have. It sounds like you have either the BCD396T, BCD396XT, BCD996T or BCD996XT - if that's right,
FreeScan - (which as the name implies, is freeware) and a USB-serial cable (since PCs these days don't have serial ports) would be needed. In the download process, you would choose to get only fire and law enforcement stuff. (By the way, anything in blue both here and in our wiki is a link)
Uniden sells their USB-1 cable, and other manufacturers would likely also work.
Before you jump into anything, I'd highly recommend reading up on the scanner, and the technology (known as Dynamic Memory Allocation or DMA) so you can fully understand how to program it, as this is completely different from the older 'bank' style of programming. We have an extensive wiki section on this site that has a number of useful articles. To start, go to the blue toolbar under the Scanner Master logo, float your mouse over
Wiki and select
FAQs. From there, go to the bottom and select the
Uniden DMA FAQ. At the bottom of this, there are links for the 'Easier to Read' online manuals which are a better read than the Uniden offering. Even if you have the XT models, if you understand the older T model scanners, it's a short logical jump to the XTs.
The FreeScan user guide is also hosted in our wiki. Select
Software from the wiki pulldown, then FreeScan User Guide.
Time for a little light reading, hi 73 Mike
