You can program the scanner to alert when you receive, a Channel or Unit ID, a Close Call hit, an ID is transmitted with an Emergency Alert, or a Tone-out hit. For each alert in the scanner, you can select from 9 different tone patterns, 15 volume settings, 7 colors (white, blue, red, yellow, magenta, green, cyan), and 2 flash patterns. With this scanner you can program in your frequencies by connecting the scanner to a computer. Below is a freeware program which works with several Uniden scanners including the Bearcat UBC3500XLT. The software runs on Windows 2000, XP, Vista & Windows 7: I use DSD+ to decode the control channel data to see what channel numbers it sends the calls to and then try and find that voice channels frequency by using another analog scanner to listen which frequency gets active with DMR signalling, and enter the channel number divided by 2 in the scanner.

This scanner can receive both civilian and military aircraft transmissions as well as receiving many more frequencies such as emergency, marine, amateur (ham radio) and other communications. Independent Alert Tone Volume – lets you set the volume level of the following tones: Key Beep, Emergency Alert, Channel Alert, and Close Call Alert.

The official UBC3500XLT Manual can be a bit difficult to understand, however there is another 'easier to understand' manual online. The links to both these manuals are below: Allows you to organize your Systems into Favorites Lists. The scanner will scan multiple Favorites Lists and Full Database at the same time. I've read that it only does either a Service Search or (what sounds like 1 only) Limit Search. Is it possible to setup multiple limit search ranges as with custom search on the Uniden? Or maybe you can edit the Service Searches?

This sensitive hand-held scanner comes complete with an antenna, rechargeable batteries and an AC adaptor. The frequency range is 25-1300MHz (with gaps) and has a maximum of 2,500 (typically 1,600) channels. See specification below. It will take some effort to get all the scanner settings dialed in but I'm sure you will be able to do it if you first log all control channels and then all voice channels and their color codes and preferable also the system id and channel numbers.BCT15, BCT15X, UBC800XLT, UBC3500XLT, BR330T, UBR330T, BCD996T, BCD996XT, BCD996P2, BCD396T, BCD396XT nacl1 wrote:The 3500XLT is not particularly user friendly for inputting data, requiring constant turning of the selector knob to find alpha numerics. The easiest way is to take advantage of the ability to connect to your PC or Mac. Get a connection cable. Mine came with a serial port connector, so I had to add a serial/USB adaptor.
