Stay as far away from the Scancrap software as possible. You need to do a couple of things;
a. Most folks I know with 396s are using both the Uniden Advanced System Director (UASD for short - available from the Uniden downloads area, which requires a free registration) and/or ARC396 (from BuTel, available from Scanner Master). To be fair, there is up and coming freeware for the 396 called
BcTool ; it's not trunking yet, but I'm willing to bet it will, soon. There are other packages - such as Scan Control, which just came out with its 6.1 release (and a copy/paste function called the 'Data Grabber' for reading RR data...). We have a wiki article on the 396 (as you hit 'wiki' in the blue toolbar, look right for 'digital trunktrackers' in the yellow box- click on that, then on the 396 link and away you go), which should be in your bookmarks. It lists almost all the software that's compatible (including Scancrap, unfortunately....) and a great deal more.
b. There is no such things as banks anymore with the DMA scanners (your 396 is one...) That requires you to think in other terms. Our
DMA FAQ article will get you started, soup to nuts. Everything from what is DMA, links for trunking and 2 very important links - UPMan's Scanner Programming article, and at the bottom, the Easy to read manual for the 330 and 396. Also becoming a paid subscriber will allow you to download data directly from the databases - there's a link for that, too (anything in blue is a link). If you need to set up for trunking and don't understand it, read the Trunking basics and FAQ articles linked there.
c. It's sometimes easiest to start with a predefined file for your area - once you have some software (lots of folks start with the UASD), go to the California forum and ask for a UASD file for your area. It's very important to be specific about the software you are using - file types are not always interchangable one from another. The 396 Yahoo group may also have files for your area - it's worth joining to see. There are numerous California based Yahoo scanning groups as well, and that might be another source.
Lots to read and understand. Go slow and you'll do fine. 73s Mike
